自动化运维——saltstack 、ansible
一、自动化运维介绍
传统运维：传统运维效率低，大多工作需要人工完成，工作繁琐，容易出错，每日重复做相同的事情，没有标准化流程，脚本过多，不方便管理。
自动化运维:解决上面所有问题。
常见自动化运维工具:
- Puppet：基于rubby开发，c/s架构，支持多平台，可管理配置文件、用户、cron任务、软件包、系统服务等。分为社区版和企业版，企业版支持图形化配置。
- Saltstack：基于Python开发，c/s架构，支持多平台，比Puppet轻量，在远程执行命令时非常快捷，配置和使用比puppet容易，能实现puppet几乎所有的功能。
- Ansible：更加简洁的自动化运维工具，不需要在客户端上安装客户端软件，基于Python开发的。可以实现批量操作系统配置、批量程序的部署、批量执行命令。
二、saltstack安装与启动
saltstack介绍文档：
saltstack操作方式
- 使用salt-ssh远程执行，类似ansible，
- 支持c/s模式
现在按照c/s模式使用，需要准备三台台机器：
| hostname | IP | 功能 |
|---|---|---|
| ying01 | 192.168.112.136 | master |
| ying02 | 192.168.112.138 | minion |
| ying03 | 192.168.112.139 | minion |
先分别在ying01、ying02、ying03上，设置hosts
# vim /etc/hosts三台机器都设置一样192.168.112.136 ying01192.168.112.138 ying02192.168.112.139 ying03
在ying01上：
安装repo仓库，然后安装 salt-master 和salt-minion包
[root@ying01 ~]# yum install -y https://repo.saltstack.com/yum/redhat/salt-repo-latest-2.el7.no[root@ying01 ~]# yum install -y salt-master salt-minion
编辑配置文件
[root@ying01 ~]# vim /etc/salt/minion#master: salt 改为 master: ying01
开启salt-master服务，并查看进程以及监听端口
[root@ying01 ~]# systemctl start salt-master； systemctl start salt-minion //开启salt-maste和minion服务[root@ying01 ~]# ps aux |grep saltroot 8784 4.0 0.7 313768 21396 ?

Sl 12:21 0:03 /usr/bin/python /usr/bin/salt-master[root@ying01 ~]# netstat -lntp|grep pythontcp 0 0 0.0.0.0:4505 0.0.0.0:* LISTEN 36619/python tcp 0 0 0.0.0.0:4506 0.0.0.0:* LISTEN 36628/python
- 监听端口4505 作用是 发布消息；也就是zeromq.x86_64 0:4.1.4-7.el7，这个包的端口。
- 监听端口4506 作用是salt-master和salt-minion通信
ying02、ying03上:
安装repo仓库，然后安装salt-minion包(注意：客户端只安装minion包)
[root@ying02 ~]# yum install -y https://repo.saltstack.com/yum/redhat/salt-repo-latest-2.el7.no[root@ying02 ~]# yum install -y salt-master salt-minion
编辑配置文件
[root@ying02 ~]# vim /etc/salt/minion#master: salt 改为 master: ying02 //ying03机器应写ying03
开启salt-minion服务，并查看进程；（注意：服务端没有监听端口，只在服务端）
[root@ying02 ~]# systemctl start salt-minion[root@ying02 ~]# ps aux |grep saltroot 5978 0.7 1.1 313768 21396 ? Ss 12:14 0:00 /usr/bin/python /usr/bin/salt-minionroot 5981 3.3 2.2 567256 42456 ? Sl 12:14 0:01 /usr/bin/python /usr/bin/salt-minionroot 5989 0.0 1.0 403992 20088 ? S 12:14 0:00 /usr/bin/python /usr/bin/salt-minionroot 6068 0.0 0.0 112720 980 pts/0 S+ 12:15 0:00 grep --color=auto salt
ying03和ying02机器，作为客户端，操作步骤一样；
三、saltstack配置认证
master端和minion端通信：
- 需要建立一个安全通道，传输过程需要加密，所以得配置认证，也是通过密钥对来加密解密的。
认证的过程：
- minion在第一次启动时会在/etc/salt/pki/minion/下生成minion.pem和minion.pub，其中.pub为公钥，它会把公钥传输给master。
- master第一次启动时也会在/etc/salt/pki/master下生成密钥对，当master接收到minion传过来的公钥后，（通过salt-key工具接受这个公钥）就会在/etc/salt/pki/master/minions/目录里存放刚刚接受的公钥，同时客户端也会接受master传过去的公钥，把它放在/etc/salt/pki/minion目录下，并命名为minion_master.pub
- 通信过程需要借助salt-key工具来实现。
- salt-key命令用法
参数 作用 -a 后面跟主机名，认证指定主机 -A 认证所有主机 -r 跟主机名，拒绝指定主机 -R 拒绝所有主机 -d 跟主机名，删除指定主机认证 -D 删除全部主机认证 -y 省略掉交互，相当于直接按了y
在ying02、ying03上，salt-minion服务启动下，/etc/salt/pki/minion/生成私钥和公钥
[root@ying02 ~]# ls /etc/salt/pki/minion/ //minion端的私钥和公钥minion.pem minion.pub[root@ying02 ~]# cat /etc/salt/pki/minion/minion.pub //minion端的公钥-----BEGIN PUBLIC KEY-----MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA7KYLLEjj/ScVG3Tn7AdsTdiXrZyKffzqzT94i6brSuZpJ8CF0C5O4GxeX3lTmlzjG2bBJuJKabijbIITG5Xop8cJh3G2f2g3vpOXo22pBGS6qHIhSp82KkPv6DK0BxwtcltLcLiR1jEcGJRdfMaIXA7R9Yn5+9seyZwaJ1XFfhFURLWcn5lARgBPlDFVh2AZZRkGE0R9s5QSVpeoymVu/i1piY36jKAE6+X2Fs3k6tIHDToeewPBPMkS/kBA0gu+yHDIM+aPsf6C6we1+uDj7IUxBGnyaEKt7iSVjkIbcfq5279L6t0DKAJ/w0nu2N7FFolyROt8CvEkmXVl+Ojr5wIDAQAB-----END PUBLIC KEY-----[root@ying02 ~]# ^C[root@ying02 ~]# ls /etc/salt/pki/minion/minion.pem //minion端的私钥文件/etc/salt/pki/minion/minion.pem
在ying01上，/etc/salt/pki/master下生成密钥对
[root@ying01 ~]# ls /etc/salt/pki/master/master.pem master.pub minions minions_autosign minions_denied minions_pre minions_rejected[root@ying01 ~]# ls -l /etc/salt/pki/master/minions //因为没有和minion相连，所以此时目录为空总用量 0[root@ying01 ~]# ls -l /etc/salt/pki/master/master.pem //master私钥文件-r-------- 1 root root 1678 9月 6 22:40 /etc/salt/pki/master/master.pem[root@ying01 ~]# cat /etc/salt/pki/master/master.pub //master公钥文件 -----BEGIN PUBLIC KEY-----MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAsOluTrUZxwa2YHWeJl9AVRCMW0eyYYPhHCbt+dkKsFY9HYOHfWqdcgGg8ZZwelBbHeEbZOqRXM7ofPucm5z9124+Wp65kgKJpdSmfwFmge+ZZ38uYoQYG2QUDPIaefAk95DquGpTLXLz9BA3YC/KiKEffkM4jS0CgyWD4191Wdmt79/VkO0nK3/QQrtAg3SXAOo2P5JEhrJE0wyk2U0jiF0t+hV9WJ9/ENdYjirq6R9leT/qp3ZoounboyIIqbEdjVzhGxahtOaoPz5Js6e3vbvun2H5/GYzSHkPQcUAub7Uh+O2smN6c7P7svVK8Hmkf0RlQD+Sy/FDkt1G1jaXZwIDAQAB-----END PUBLIC KEY-----[root@ying01 ~]#
现在用salt-key工具认证ying02、ying03机器；salt-key -a hostname
[root@ying01 ~]# salt-key -a ying02 //认证ying02The following keys are going to be accepted:Unaccepted Keys:ying02Proceed?

重新认证主机，可以salt-key -A，但是必须在三台机器上重启： systemctl restart salt-minion
[root@ying01 ~]# systemctl restart salt-minion //注意ying02、ying03机器也要重启 salt-minion服务[root@ying01 ~]# salt-key -AThe following keys are going to be accepted:Unaccepted Keys:ying01ying02ying03Proceed?

四、saltstack远程执行命令
salt '*' test.ping：测试所有认证主机是否存活
[root@ying01 ~]# salt '*' test.ping ying02: Trueying03: Trueying01: True
注意：这里的*必须是在master上已经被接受过认证的客户端，可以通过salt-key查到，通常是我们已经设定的id值。也可以指定一个认证用户，比如 salt 'yin01' test.ping
salt '*' cmd.run "命令" ： 在所有认证用户上执行命令
[root@ying01 ~]# salt '*' cmd.run "hostname" //显示所有机器的主机名ying03: ying03ying02: ying02ying01: ying01[root@ying01 ~]# salt '*' cmd.run "tail -n2 /etc/passwd" //显示所有主机下/etc/passwd文件最后两行内容ying03: nginx:x:997:995:Nginx web server:/var/lib/nginx:/sbin/nologin mongod:x:996:994:mongod:/var/lib/mongo:/bin/falseying02: tss:x:59:59:Account used by the trousers package to sandbox the tcsd daemon:/dev/null:/sbin/nologin git:x:1001:1001::/home/git:/usr/bin/git-shellying01: gitlab-psql:x:991:987::/var/opt/gitlab/postgresql:/bin/sh gitlab-prometheus:x:990:986::/var/opt/gitlab/prometheus:/bin/sh [root@ying01 ~]# salt 'ying01' cmd.run "hostname" //只打印ying01ying01: ying01[root@ying01 ~]# salt 'ying02' cmd.run "hostname" ying02: ying02[root@ying01 ~]# salt 'ying*' cmd.run "hostname" //支持正则，通配符ying03: ying03ying01: ying01ying02: ying02[root@ying01 ~]# salt 'ying0[23]' cmd.run "hostname" //显示02、03ying03: ying03ying02: ying02
salt -L 'ying01,ying03' cmd.run "hostname" 显示指定多个用户，中间用逗号隔开
[root@ying01 ~]# salt -L 'ying01,ying03' cmd.run "hostname" ying01: ying01ying03: ying03
salt -E 'ying[0-9]+' cmd.run "hostname" -E 可以使用正则
[root@ying01 ~]# salt -E 'ying[0-9]+' cmd.run "hostname"ying01: ying01ying02: ying02ying03: ying03[root@ying01 ~]# salt -E 'ying0[0-9]' cmd.run "hostname"ying02: ying02ying01: ying01ying03: ying03[root@ying01 ~]# salt -E 'ying[0-9]' cmd.run "hostname"ying03: ying03ying02: ying02ying01: ying01[root@ying01 ~]# salt -E 'ying(02|03)' cmd.run "hostname"ying03: ying03ying02: ying02[root@ying01 ~]#
五、saltstack – grains
grains是在minion启动时收集到的一些信息，比如操作系统类型、网卡ip、内核版本、cpu架构等。
- 默认grains配置
在master端ying01上，列出ying02机器上grains项目名字
[root@ying01 ~]# salt 'ying02' grains.ls ying02: - SSDs - biosreleasedate - biosversion - cpu_flags - cpu_model - cpuarch - disks - dns - domain - fqdn - fqdn_ip4 - fqdn_ip6 - gid - gpus - groupname - host - hwaddr_interfaces - id - init - ip4_gw - ip4_interfaces - ip6_gw - ip6_interfaces - ip_gw - ip_interfaces - ipv4 - ipv6 - kernel - kernelrelease - kernelversion - locale_info - localhost - lsb_distrib_codename - lsb_distrib_id - machine_id - manufacturer - master - mdadm - mem_total - nodename - num_cpus - num_gpus - os - os_family - osarch - oscodename - osfinger - osfullname - osmajorrelease - osrelease - osrelease_info - path - pid - productname - ps - pythonexecutable - pythonpath - pythonversion - saltpath - saltversion - saltversioninfo - selinux - serialnumber - server_id - shell - swap_total - systemd - uid - username - uuid - virtual - zfs_feature_flags - zfs_support - zmqversion
salt 'ying02' grains.items 列出ying02机器上grains项目以及值
[root@ying01 ~]# salt 'ying02' grains.items //篇幅关系，只列出部分ying02: ---------- SSDs: biosreleasedate: 07/31/2013 biosversion: 6.00 cpu_flags: - fpu - vme - de - pse - tsc - msr - pae
salt 'ying02' grains.item dns 列出ying02机器上grains中dns项目及其值
[root@ying01 ~]# salt 'ying02' grains.item dnsying02: ---------- dns: ---------- domain: ip4_nameservers: - 119.29.29.29 ip6_nameservers: nameservers: - 119.29.29.29 options: search: sortlist:[root@ying01 ~]# salt 'ying02' grains.item hwaddr_interfaces //同样列出hwaddr_interfaces项目的值ying02: ---------- hwaddr_interfaces: ---------- ens33: 00:0c:29:c6:2c:24 ens37: 00:0c:29:c6:2c:2e lo: 00:00:00:00:00:00
- 自定义grain文件
在客户端ying02上新建vim /etc/salt/grains文件，并重启salt-minion服务
[root@ying02 ~]# vim /etc/salt/grainsrole: nginx env: test[root@ying02 ~]# systemctl restart salt-minion.service
salt '*' grains.item role env ：列出role、env项目的值
[root@ying01 ~]# salt '*' grains.item role envying02: ---------- env: test role: nginxying03: ---------- env: test role: httpdying01: ---------- env: role:[root@ying01 ~]# salt '*' grains.item feng //feng无定义此项目，所以显示无ying02: ---------- feng:ying03: ---------- feng:ying01: ---------- feng:
六、saltstack – pillar
pillar和grains不一样，是在master上定义的，并且是针对minion定义的一些信息。像一些比较重要的数据（密码）可以存在pillar里，还可以定义变量等
- 加载saltstack配置文件中的pillar
在master主机（ying01）修改/etc/salt/master文件，加载pillar配置
[root@ying01 ~]# vim /etc/salt/master#pillar_roots: //去掉#号# base: //去掉#号# - /srv/pillar //去掉#号
重启salt-master服务，创建在配置文件（master文件）定义的目录。
[root@ying01 ~]# systemctl restart salt-master[root@ying01 ~]# mkdir /srv/pillar
- 自定义配置自定义pillar
切换到此目录下，创建子配置test.sls文件，这个文件salt不会直接加载需要创建，引导文件
[root@ying01 ~]# cd /srv/pillar[root@ying01 pillar]# vim test.sls conf: /etc/123.conf
创建引导文件top.sls
[root@ying01 pillar]# vim /srv/pillar/top.slsbase: 'ying02'： //在ying02机器下 - test //加载test配置
当更改完pillar配置文件后，我们可以通过刷新pillar配置来获取新的pillar状态
[root@ying01 pillar]# salt '*' saltutil.refresh_pillar //刷新ying02: Trueying01: Trueying03: True[root@ying01 pillar]# salt '*' pillar.item confying02: ---------- conf: /etc/123.conf ying01: ---------- conf:ying03: ---------- conf:
- top文件可以添加多个子配置文件
分别创建test2.sls 、test2.sls子配置文件
[root@ying01 pillar]# vim test2.sls zzz: /date/test2[root@ying01 pillar]# vim test3.sls qqq: /tmp/test3
在把上面2个子配置文件，添加到top文件
[root@ying01 pillar]# vim top.sls base: 'ying02': - test - test1 'ying03': - test2 - test3
查看项目 www、conf、zzz、qqq
[root@ying01 pillar]# salt '*' saltutil.refresh_pillarying02: Trueying03: Trueying01: True[root@ying01 pillar]# salt '*' pillar.item www conf zzz qqqying03: ---------- conf: qqq: /tmp/test3 www: zzz: /date/test2ying02: ---------- conf: /etc/123.conf qqq: www: /date/123 zzz:ying01: ---------- conf: qqq: www: zzz:
- 可以把多个子配置文件写在一个子配置里
比如在test4中，创建3个项目，相当于包含3个子配置文件
[root@ying01 pillar]# vim test4.sls AAA: /tmp/test3BBB: /tmp/okCCC: /tmp/nba[root@ying01 pillar]# vim top.sls //把test4添加到引导文件top.sls中base: 'ying02': - test - test1 'ying03': - test2 - test3 'ying01': - test4
刷新测试，test4中项目都会列出来
[root@ying01 pillar]# salt '*' saltutil.refresh_pillar //刷新配置文件[root@ying01 pillar]# salt '*' pillar.item AAA BBB CCCying01: ---------- AAA: /tmp/test3 BBB: /tmp/ok CCC: /tmp/nbaying03: ---------- AAA: BBB: CCC:ying02: ---------- AAA: BBB: CCC:
七、saltstack安装配置httpd
在master主机（ying01）修改/etc/salt/master文件，加file_roots配置
[root@ying01 ~]# vim /etc/salt/master # file_roots: //去掉#号# base: //去掉#号，前面2个空格# - /srv/salt/ //去掉#号，前面4个空格
重启salt-master服务，创建在配置文件（master文件）定义的目录。
[root@ying01 ~]# systemctl restart salt-master[root@ying01 ~]# mkdir /srv/salt[root@ying01 ~]# cd /srv/salt/
创建top引导文件，意思是 在所有主机上加载httpd模块
[root@ying01 salt]# vim /srv/salt/top.slsbase: '*': //星号，代表所有认证主机 - httpd //加载httpd模块
新建httpd模块配置文件
[root@ying01 salt]# vim httpd.slshttpd-service: //id的名称，可以自定义 pkg.installed: //包安装函数 - names: //加载服务名称； 如果要安装一个服务，写成： -names: httpd 不用换行 - httpd //要加载的服务1 - httpd-devel //要加载的服务2 service.running: //来保证指定的服务启动的函数 - name: httpd //启动服务的名称是 httpd - enable: True //ture 表示开机启动，
查看3台机器是否安装httpd服务；系统服务都在这个目录下：/lib/systemd/system
[root@ying01 salt]# ls /lib/systemd/system |grep httpd //ying01机器httpd服务httpd.service[root@ying02 ~]# ls /lib/systemd/system |grep httpd //ying02上没有此服务[root@ying03 ~]# ls /lib/systemd/system |grep httpd //ying02上没有此服务
在ying01上给ying02安装httpd服务
[root@ying01 salt]# salt-key //认证的主机Accepted Keys:ying01ying02ying03Denied Keys:Unaccepted Keys:Rejected Keys:[root@ying01 salt]# salt 'ying02' state.highstate //state.highstate会加载/srv/salt/top.sls中模块
在执行 salt 'aming-02' state.highstate 执行过程会比较慢，因为ying02客户端上在yum install httpd httpd-devel；在master执行命令的时候，机器会在后台安装，此时到ying02上可以看到yum、httpd进程，说明httpd服务正在通过mater机器
[root@ying02 ~]# ps aux |grep yumroot 26256 2.5 1.5 328292 28268 ? Sl 10:45 0:00 /usr/bin/python /usr/bin/yum --quiet --assumeyes check-update --setopt=autocheck_running_kernel=falseroot 26284 0.0 0.0 112720 980 pts/0 S+ 10:45 0:00 grep --color=auto yum[root@ying02 ~]# ps aux |grep yumroot 26323 44.7 3.8 517040 71984 ?

几分钟后，在master上出现执行结果反馈的信息
[root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: httpd-service Function: pkg.installed Name: httpd Result: True Comment: All specified packages are already installed Started: 11:12:04.700830 Duration: 880.223 ms Changes: ---------- ID: httpd-service Function: pkg.installed Name: httpd-devel Result: True Comment: All specified packages are already installed Started: 11:12:05.581273 Duration: 28.955 ms Changes: ---------- ID: httpd-service Function: service.running Name: httpd Result: False //有错误 Comment: Running scope as unit run-27315.scope.

从上面信息，可以看出 service.running 模块加载有问题，那说明是httpd启动有问题
到客户端ying02上，查看日志信息
[root@ying02 ~]# cat /var/log/salt/minion |grep httpd2018-09-09 10:50:24,722 [salt.loaded.int.module.cmdmod:753 ][ERROR ][26156] Command '[u'systemd-run', u'--scope', u'systemctl', 'start', u'httpd.service']' failed with return code: 1Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.
打开端口查看，我们发现httpd启动所需要的80端口，被nginx占用，停止nginx服务
[root@ying02 ~]# netstat -lnptActive Internet connections (only servers)Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 535/rpcbind tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1023/nginx: master tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 836/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1064/master tcp 0 0 0.0.0.0:10050 0.0.0.0:* LISTEN 867/zabbix_agentd tcp 0 0 192.168.112.138:27017 0.0.0.0:* LISTEN 1151/mongod tcp 0 0 127.0.0.1:27017 0.0.0.0:* LISTEN 1151/mongod tcp6 0 0 :::111 :::* LISTEN 535/rpcbind tcp6 0 0 :::22 :::* LISTEN 836/sshd tcp6 0 0 ::1:25 :::* LISTEN 1064/master tcp6 0 0 :::10050 :::* LISTEN 867/zabbix_agentd [root@ying02 ~]# /etc/init.d/nginx stopStopping nginx (via systemctl): [ 确定 ]
现开启httpd服务
[root@ying02 ~]# systemctl start httpd[root@ying02 ~]# netstat -lnpt |grep httpdtcp6 0 0 :::80 :::* LISTEN 28117/httpd [root@ying02 ~]# ps aux |grep httpdroot 28117 0.0 0.2 224020 4996 ?

OK，成功启动，说明在用salt远程安装的时候，应该把注意客户机已开启的服务对即将进行的安装，是否产生干涉；
再运行一次，检测
[root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: httpd-service Function: pkg.installed Name: httpd Result: True Comment: All specified packages are already installed Started: 11:52:08.191272 Duration: 988.077 ms Changes: ---------- ID: httpd-service Function: pkg.installed Name: httpd-devel Result: True Comment: All specified packages are already installed Started: 11:52:09.179540 Duration: 25.382 ms Changes: ---------- ID: httpd-service Function: service.running Name: httpd Result: True Comment: Service httpd has been enabled, and is in the desired state Started: 11:52:09.205649 Duration: 187.809 ms Changes: ---------- httpd: TrueSummary for ying02------------Succeeded: 3 (changed=1)Failed: 0------------Total states run: 3Total run time: 1.201 s
如果给所有认证主机安装，只需要把ying02改为*
[root@ying01 salt]# salt-key Accepted Keys:ying01ying02ying03Denied Keys:Unaccepted Keys:Rejected Keys:[root@ying01 salt]# salt '*' state.highstate
如果部分安装，那么就把不安装 取消认证
[root@ying01 salt]# salt-key Accepted Keys:ying02ying03Denied Keys:Unaccepted Keys:ying01Rejected Keys:[root@ying01 salt]# salt '*' state.highstate
注意：state.highstate会读取所有环境（包括base环境）的top.sls文件，并且执行top.sls文件内容里面定义的sls文件，不在top.sls文件里面记录的sls则不会被执行；
八、 配置管理文件
创建test.sls文件，写入以下语句；
[root@ying01 salt]# pwd/srv/salt[root@ying01 salt]# vim test.slsfile_test: //配置文件名称，可以自定义 file.managed: - name: /tmp/ying.com //定义name属性 - source: salt://test/123/1.txt //定义来源目录， salt：// == /srv/salt/（master配置文件里面设置） - user: root //定义所有者属性 - group: root //定义组属性 - mode: 600 //定义文件权限
file_test 的含义，把指定目录下1.txt文件，同步到ying.com这个文件；修改1.txt文件内容，ying.com文件内容和其保持一致；并且指定gid、uid，以及权限；
创建test.sls文件中，定义的目录、文件
[root@ying01 salt]# mkdir -p test/123/ //创建连级目录[root@ying01 salt]# touch test/123/1.txt //新建1.txt文件[root@ying01 salt]# tree.├── httpd.sls├── test│ └── 123│ └── 1.txt├── test.sls└── top.sls2 directories, 4 files
编辑top.sls文件，定义运行环境以及需要运行sls
[root@ying01 salt]# vim top.slsbase: '*': - test
针对认证主机ying02 加载top文件
[root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: file_test Function: file.managed Name: /tmp/ying.com Result: True //运行成功 Comment: File /tmp/ying.com updated Started: 23:50:10.716486 Duration: 428.142 ms Changes: ---------- diff: New file Summary for ying02------------Succeeded: 1 (changed=1)Failed: 0------------Total states run: 1Total run time: 428.142 ms
1.txt文件里面为空，所以在yong02机器上ying.com问价也为空；
[root@ying02 ~]# ls -lt /tmp/ying.com-rw------- 1 root root 0 9月 9 23:50 /tmp/ying.com
把1.txt写入内容
[root@ying01 salt]# echo "AAAAAAAA" >> ./test/123/1.txt [root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: file_test Function: file.managed Name: /tmp/ying.com Result: True Comment: File /tmp/ying.com updated Started: 23:54:30.173156 Duration: 70.924 ms Changes: ---------- diff: --- +++ @@ -0,0 +1 @@ +AAAAAAAASummary for ying02------------Succeeded: 1 (changed=1)Failed: 0------------Total states run: 1Total run time: 70.924 ms
客户端ying02上，/tmp/ying.com内容和1.txt保持一致；
[root@ying02 ~]# ls -lt /tmp/ying.com-rw------- 1 root root 9 9月 9 23:54 /tmp/ying.com[root@ying02 ~]# cat /tmp/ying.comAAAAAAAA
九、配置管理目录
继续创建test_dir.sls文件
[root@ying01 salt]# pwd/srv/salt[root@ying01 salt]# vim test_dir.sls file_dir: file.recurse: - name: /tmp/testdir - source: salt://test/123 //同步123目录 - user: root - file_mode: 640 //文件权限 - dir_mode: 750 //目录权限 - mkdir: True //ture为自动创建目录 - clean: True //master删除文件或者目录，客户端上也一样
编辑tops.sls文件，把test_dir模块写入；
[root@ying01 salt]# vim top.sls base: '*': - test - test_dir
针对认证主机ying02 加载top.sls文件
[root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: file_test Function: file.managed Name: /tmp/ying.com Result: True Comment: File /tmp/ying.com is in the correct state Started: 19:29:26.543760 Duration: 211.749 ms Changes: ---------- ID: file_dir Function: file.recurse Name: /tmp/testdir Result: True Comment: Recursively updated /tmp/testdir Started: 19:29:26.755899 Duration: 155.935 ms Changes: ---------- /tmp/testdir/1.txt: ---------- diff: New file mode: 0640Summary for ying02------------Succeeded: 2 (changed=1)Failed: 0------------Total states run: 2Total run time: 367.684 ms
到客户端ying02上查看，有/tmp/testdir目录生成，及其目录下1.txt生成
[root@ying02 ~]# ls -ld /tmp/testdir //目录权限为750drwxr-x--- 2 root root 19 9月 10 19:29 /tmp/testdir[root@ying02 ~]# ls -l /tmp/testdir //文件权限为640总用量 4-rw-r----- 1 root root 9 9月 10 19:29 1.txt[root@ying02 ~]# tree /tmp/testdir//tmp/testdir/└── 1.txt
那么在master（ying01）上，在123目录下创建1个子目录456
[root@ying01 salt]# mkdir test/123/456[root@ying01 salt]# tree.├── httpd.sls├── test│ └── 123│ ├── 1.txt│ ├── 2.txt│ └── 456├── test_dir.sls├── test.sls└── top.sls3 directories, 6 files[root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: file_test Function: file.managed Name: /tmp/ying.com Result: True Comment: File /tmp/ying.com is in the correct state Started: 19:39:28.107455 Duration: 72.394 ms Changes: ---------- ID: file_dir Function: file.recurse Name: /tmp/testdir Result: True Comment: The directory /tmp/testdir is in the correct state Started: 19:39:28.180151 Duration: 77.957 ms Changes: Summary for ying02------------Succeeded: 2Failed: 0------------Total states run: 2Total run time: 150.351 ms
到客户端ying02上查看，在/tmp/testdir目录却没有456目录生成；
[root@ying02 ~]# tree /tmp/testdir//tmp/testdir/├── 1.txt└── 2.txt0 directories, 2 files
注意：如果source对应的目录里有空目录（456）的话，客户端上不会创建该目录(456);
在master(ying01)机器上，在456目录下创建8.txt文件，使其目录不wei空；
[root@ying01 salt]# touch test/123/456/8.txt[root@ying01 salt]# tree.├── httpd.sls├── test│ └── 123│ ├── 1.txt│ ├── 2.txt│ └── 456│ └── 8.txt├── test_dir.sls├── test.sls└── top.sls3 directories, 7 files[root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: file_test Function: file.managed Name: /tmp/ying.com Result: True Comment: File /tmp/ying.com is in the correct state Started: 19:41:22.171153 Duration: 56.488 ms Changes: ---------- ID: file_dir Function: file.recurse Name: /tmp/testdir Result: True Comment: Recursively updated /tmp/testdir Started: 19:41:22.227945 Duration: 202.525 ms Changes: ---------- /tmp/testdir/456: ---------- /tmp/testdir/456: New Dir /tmp/testdir/456/8.txt: ---------- diff: New file mode: 0640Summary for ying02------------Succeeded: 2 (changed=1)Failed: 0------------Total states run: 2Total run time: 259.013 ms
此时在客户端ying02上，/tmp/testdir/目录下有456目录及其子文件生成；
[root@ying02 ~]# tree /tmp/testdir//tmp/testdir/├── 1.txt├── 2.txt└── 456 └── 8.txt1 directory, 3 files
十、配置管理远程命令
[root@ying01 salt]# vim shell_test.slshell_test: cmd.script: - source: salt://test/1.sh - user: root
[root@ying01 salt]# vim test/1.sh#!/bin/bashtouch /tmp/111.txtif [ ! -d /tmp/1233 ]then mkdir /tmp/1233fi
[root@ying01 salt]# vim top.sls base: '*': - shell_test
[root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: hell_test Function: cmd.script Result: True Comment: Command 'hell_test' run Started: 21:12:27.077124 Duration: 73.007 ms Changes: ---------- pid: 13157 retcode: 0 stderr: stdout:Summary for ying02------------Succeeded: 1 (changed=1)Failed: 0------------Total states run: 1Total run time: 73.007 ms
在客户端ying02上,检测在/tmp/下是否有1233目录，111.txt生成
[root@ying02 ~]# ls -lt /tmp/总用量 4drwxr-xr-x 2 root root 6 9月 10 21:12 1233 //有生成-rw-r--r-- 1 root root 0 9月 10 21:12 111.txt //有生成drwxr-x--- 3 root root 43 9月 10 19:41 testdirsrwx------ 1 mongod mongod 0 9月 10 13:37 mongodb-27017.sockdrwx------ 3 root root 17 9月 10 13:35 systemd-private-0b08a1b2dc044a57b06946b4bcf525b4-chronyd.service-euzZsidrwx------ 3 root root 17 9月 10 13:35 systemd-private-0b08a1b2dc044a57b06946b4bcf525b4-vmtoolsd.service-Ijaqtzdrwx------ 3 root root 17 9月 10 13:35 systemd-private-0b08a1b2dc044a57b06946b4bcf525b4-vgauthd.service-TolUVQ-rw------- 1 root root 9 9月 9 23:54 ying.com
[root@ying01 salt]# vim top.sls base: '*': - cron_test
十一、配置管理计划任务
- 创建计划任务
定义cron_test.sls配置文件
[root@ying01 salt]# vim cron_test.slscron_test: cron.present: - name: /bin/touch /tmp/111.txt - user: root - minute: '*' - hour: 20 - daymonth: '*' - month: '*' - dayweek: '*'
创建top.sls 引导文件
[root@ying01 salt]# vim top.sls base: '*': - cron_test
针对主机ying02，进行状态刷新
[root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: cron_test Function: cron.present Name: /bin/touch /tmp/111.txt Result: True Comment: Cron /bin/touch /tmp/111.txt added to root's crontab Started: 21:37:39.312465 Duration: 297.174 ms Changes: ---------- root: /bin/touch /tmp/111.txtSummary for ying02------------Succeeded: 1 (changed=1)Failed: 0------------Total states run: 1Total run time: 297.174 ms
在主机ying02上，查看计划任务
[root@ying02 ~]# crontab -l# Lines below here are managed by Salt, do not edit# SALT_CRON_IDENTIFIER:/bin/touch /tmp/111.txt* 20 * * * /bin/touch /tmp/111.txt
编辑 cron_test.sls配置文件，把minute 改为58分
[root@ying01 salt]# vim cron_test.slscron_test: cron.present: - name: /bin/touch /tmp/111.txt - user: root - minute: '58' //修改此计划 - hour: 20 - daymonth: '*' - month: '*' - dayweek: '*'
再次对ying02刷新状态
[root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: cron_test Function: cron.present Name: /bin/touch /tmp/111.txt Result: True Comment: Cron /bin/touch /tmp/111.txt updated Started: 21:48:49.306192 Duration: 312.716 ms Changes: ---------- root: /bin/touch /tmp/111.txtSummary for ying02------------Succeeded: 1 (changed=1)Failed: 0------------Total states run: 1Total run time: 312.716 ms
在主机ying02上，查看计划任务，发现计划任务更改，试验成功
[root@ying02 ~]# crontab -l# Lines below here are managed by Salt, do not edit# SALT_CRON_IDENTIFIER:/bin/touch /tmp/111.txt58 20 * * * /bin/touch /tmp/111.txt
- 删除此计划
把配置文件中 cron.present: 改为 cron.absent: 表示取消任务
[root@ying01 salt]# vim cron_test.slscron_test: cron.absent: - name: /bin/touch /tmp/111.txt
刷新状态
[root@ying01 salt]# salt 'ying02' state.highstateying02:---------- ID: cron_test Function: cron.absent Name: /bin/touch /tmp/111.txt Result: True Comment: Cron /bin/touch /tmp/111.txt removed from root's crontab Started: 21:53:00.019619 Duration: 167.855 ms Changes: ---------- root: /bin/touch /tmp/111.txtSummary for ying02------------Succeeded: 1 (changed=1)Failed: 0------------Total states run: 1Total run time: 167.855 ms
此时在ying02上，查看计划任务列表，已经为空，说明计划列表删除
[root@ying02 ~]# crontab -l# Lines below here are managed by Salt, do not edit[root@ying02 ~]#
十二、 saltstack – 其它常用命令
- 拷贝master上的文件到客户端：cp.get_file
[root@ying01 salt]# salt -L 'ying02,ying03' cp.get_file salt://test/123/1.txt /tmp/aaa.txtying02: /tmp/aaa.txtying03: /tmp/aaa.txt
在客户端ying01、ying02上查看复制的结果；
[root@ying02 ~]# ls -l /tmp/aaa.txt -rw-r--r-- 1 root root 9 9月 11 12:03 /tmp/aaa.txt[root@ying03 ~]# ls -l /tmp/aaa.txt -rw-r--r-- 1 root root 9 9月 11 12:03 /tmp/aaa.txt
- 拷贝master上的目录到客户端：cp.get_dir
[root@ying01 salt]# salt 'ying0[23]' cp.get_dir salt://test/123/ /tmp/ying03: - /tmp//123/1.txt - /tmp//123/2.txt - /tmp//123/456/8.txtying02: - /tmp//123/1.txt - /tmp//123/2.txt - /tmp//123/456/8.txt
在客户端端查看复制结果
[root@ying02 ~]# ls -la /tmp/123总用量 12drwxr-xr-x 3 root root 43 9月 11 12:13 .drwxrwxrwt. 16 root root 4096 9月 11 12:13 ..-rw-r--r-- 1 root root 9 9月 11 12:13 1.txt-rw-r--r-- 1 root root 9 9月 11 12:13 2.txtdrwxr-xr-x 2 root root 19 9月 11 12:13 456
- 显示存活的minion
[root@ying01 salt]# salt-run manage.up- ying01- ying02- ying03
- 批量执行脚本，命令行下执行master上的shell脚本
[root@ying01 salt]# salt '*' cmd.script salt://test/1.shying02: ---------- pid: 19885 retcode: 0 stderr: stdout:ying03: ---------- pid: 4331 retcode: 0 stderr: stdout:ying01: ---------- pid: 34919 retcode: 0 stderr: stdout:
十三、salt-ssh使用
salt-ssh不需要对客户端做认证，客户端也不用安装salt-minion，它类似pssh/expect
编辑roster文件，添加以下机器的内容
[root@ying01 salt]# vim /etc/salt/roster ying01 host: 192.168.112.136 user: root passwd: ssss1234ying02 host: 192.168.112.138 user: root passwd: ssss1234ying03 host: 192.168.112.139 user: root passwd: ssss1234
第一次执行的时候会自动把本机的公钥放到对方机器上，然后就可以把roster里面的密码去掉
[root@ying01 salt]# salt-ssh --key-deploy '*' -r 'w' ying03: ---------- retcode: 0 stderr: stdout: root@192.168.112.139's password: 12:41:34 up 12:42, 1 user, load average: 0.00, 0.01, 0.05 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0 192.168.112.1 11:49 27:10 0.04s 0.04s -bashying02: ---------- retcode: 0 stderr: stdout: root@192.168.112.138's password: 12:41:34 up 12:42, 1 user, load average: 0.00, 0.01, 0.05 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0 192.168.112.1 11:49 27:18 0.12s 0.12s -bashying01: ---------- retcode: 0 stderr: stdout: root@192.168.112.136's password: 12:41:34 up 12:42, 1 user, load average: 0.20, 0.06, 0.08 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0 192.168.112.1 11:49 14.00s 11.02s 1.11s /usr/bin/python /usr/bin/salt-ssh --key-deploy * -r w[root@ying01 salt]#
删除登录密码
现在再编辑roster文件，把个机器的密码取消；
[root@ying01 salt]# vim /etc/salt/roster ying01: host: 192.168.112.136 user: rootying02: host: 192.168.112.138 user: rootying03: host: 192.168.112.139 user: root~
再执行命令，能够成功，说明公钥已经推送到各个客户端上
[root@ying01 salt]# salt-ssh --key-deploy '*' -r 'w' ying01: ---------- retcode: 0 stderr: stdout: 12:46:48 up 12:47, 1 user, load average: 0.04, 0.05, 0.06 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0 192.168.112.1 11:49 8.00s 2.11s 0.11s /usr/bin/python /usr/bin/salt-ssh --key-deploy * -r wying03: ---------- retcode: 0 stderr: stdout: 12:46:48 up 12:47, 1 user, load average: 0.05, 0.03, 0.05 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0 192.168.112.1 11:49 2:32 0.04s 0.04s -bashying02: ---------- retcode: 0 stderr: stdout: 12:46:48 up 12:47, 1 user, load average: 0.00, 0.01, 0.05 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0 192.168.112.1 11:49 2:32 0.12s 0.12s -bash
