saltstack 自动化运维神器（四）salt-ssh

        satlstack号称自动化运维的利器，那么saltstack能不能实现自身的批量部署呢？如果你也有这样的疑问，那么就更要看这篇文章了。答案当然是肯定的啦！saltstack可以利用salt-ssh来实现自身的批量部署。首先看待salt-ssh，很容易想到它是一个依赖 ssh 来进行远程命令执行的工具，这样做的好处是你不必在客户端安装minion程序，就可以实现远程命令的执行，而且salt-ssh支持salt的绝大部分功能。

10.10.10.4      salt-master    os：redhat6.5            master
10.10.10.5      compute1     os：redhat6.5            minion
10.10.10.6      compute2     os：redhat6.5            minion
10.10.10.7      manager01   os：redhat6.5            minion
10.10.10.8      horsizon       os：redhat6.5            minion

1、配置roster状态文件

[root@salt-master ~]# cat /etc/salt/roster 
compute1:
  host: compute1       //主机名
  user: root           //用户名
  passwd: salt_passwd  //密码
  port: 22             //端口
  timeout: 3           //超时次数
compute2:
  host: compute2
  user: root
  passwd: salt_passwd
  port: 22
  timeout: 3
[root@salt-master ~]# salt-ssh '*' test.ping
compute1:
    True
compute2:
    True
manager01:
    True

## 需要注意的是，由于salt-ssh并没有继承salt的zeroMQ，所以执行起来要慢的多，-r选项可以执行系统命令

[root@salt-master salt]# salt-ssh '*' -r 'uptime'
compute1:
    ----------
    retcode:
        0
    stderr:
        
    stdout:
         12:47:26 up  3:37,  0 users,  load average: 0.00, 0.00, 0.00
        
compute2:
    ----------
    retcode:
        0
    stderr:
        
    stdout:
         12:47:26 up  3:35,  0 users,  load average: 0.00, 0.00, 0.00

2、使用salt-ssh部署

OK，那现在我们可以通过salt-ssh开始部署minion的部署。

[root@salt-master salt]# vim epel/
salt_install.sls  test.sls          
[root@salt-master salt]# vim epel/salt_install.sls 

clear_yum:
  cmd.run:
    - name: yum clean all   //清除一下yum缓存

cache_yum:
  cmd.run:
    - name: yum makecache  //重新生成最新的yum缓存

salt_install:
  pkg.installed:
    - name: salt-minion   //指定安装的软件包

[root@salt-master salt]# salt-ssh compute2 state.sls epel.salt_install
compute2:
    ----------
    cmd_|-cache_yum_|-yum makecache_|-run:
        ----------
        __run_num__:

        changes:
