saltstack远程执行命令.md

saltstack 支持在master上向client 远程执行命令,并显示命令执行的结果

命令格式:


salt '<操作目标>'  <方法> [参数]

示例

  • 示例1 ping检查agent

*:代表所有minion主机;test:模块; ping:test模块的一个方法,这里的单引号也可以使用双引号

[root@stack-master ~]# salt '*'  test.ping

stack-master:

    True

stack-node01:

    True

stack-node02:

    True

  • 示例2 执行命令

使用cmd.run远程执行命令,cmd是模块,run是cmd模块的一个方法

[root@stack-master ~]# salt '*'  cmd.run "free -m"

stack-master:

                 total       used       free     shared    buffers     cached

    Mem:          1877        670       1207          0         28        225

    -/+ buffers/cache:        415       1461

    Swap:         4095          0       4095

stack-node01:

                 total       used       free     shared    buffers     cached

    Mem:          1877        377       1499          0         27        223

    -/+ buffers/cache:        126       1751

    Swap:         4095          0       4095

stack-node02:

                 total       used       free     shared    buffers     cached

    Mem:          1877        377       1499          0         28        223

    -/+ buffers/cache:        125       1751

    Swap:         4095          0       4095



针对<操作目标> saltstack 提供了多种方法对client(id)进行过滤

  • 普通匹配

匹配所有 '*'

匹配单个  'minion_id'

  • 正则匹配

使用-E ,--pcre 进行正则匹配


[root@stack-master ~]# salt -E '^stack-node\w+'  cmd.run "free -m"

stack-node01:

                 total       used       free     shared    buffers     cached

    Mem:          1877        377       1499          0         27        223

    -/+ buffers/cache:        126       1751

    Swap:         4095          0       4095

stack-node02:

                 total       used       free     shared    buffers     cached

    Mem:          1877        377       1499          0         28        223

    -/+ buffers/cache:        125       1751

    Swap:         4095          0       4095

  • 列表匹配

-L,--list,以主机id名列表的形式进行过滤,格式与Python的列表相似,即不同主机id 名称使用逗号分隔


[root@stack-master ~]# salt -L 'stack-node01,stack-node02'  cmd.run "free -m"

stack-node02:

                 total       used       free     shared    buffers     cached

    Mem:          1877        376       1501          0         28        223

    -/+ buffers/cache:        123       1753

    Swap:         4095          0       4095

stack-node01:

                 total       used       free     shared    buffers     cached

    Mem:          1877        378       1499          0         28        223

    -/+ buffers/cache:        126       1751

    Swap:         4095          0       4095

  • IP匹配

-S,--ipcidr,根据被控主机的IP地址或IP子网进行匹配


[root@stack-master ~]# salt -S 172.16.202.0/24  cmd.run "free -m"

stack-master:

                 total       used       free     shared    buffers     cached

    Mem:          1877        676       1201          0         30        225

    -/+ buffers/cache:        420       1457

    Swap:         4095          0       4095

stack-node01:

                 total       used       free     shared    buffers     cached

    Mem:          1877        378       1498          0         28        223

    -/+ buffers/cache:        126       1751

    Swap:         4095          0       4095

stack-node02:

                 total       used       free     shared    buffers     cached

    Mem:          1877        376       1500          0         28        223

    -/+ buffers/cache:        123       1753

    Swap:         4095          0       4095
