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__: 1 changes: ---------- pid: 10311 retcode: 0 stderr: This system is not registered to Red Hat Subscription Management.
