02 . SaltStack高级用法(Python API)

Python API简单使用

第一条命令

/usr/bin/salt默认使用的接口是LocalClient，该接口只能在salt master上使用

>>> import salt.client
>>> local = salt.client.LocalClient()
>>> local.cmd('*','cmd.run',['hostname'])
{'slave': 'slave'}

逐条返回结果

>>> ret = local.cmd_iter('*','test.ping')
>>> for i in ret:
...     print i
... 
{'slave': {'retcode': 0, 'ret': True}}

检查minion服务器信息

>>> local.cmd('*','cmd.run',['hostname'])
{'slave': 'slave'}
>>> local.cmd('*','cmd.run',['ifconfig'])
{'slave': 'ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

>>> local.cmd('*','cmd.run',['crontab -l'])
{'slave': 'no crontab for root'}
>>> local.cmd('*','cmd.run',['df -h'])

控制minion的服务

>>> local.cmd('*','service.stop',['nginx'])
{'slave': True}
>>> local.cmd('*','service.status',['nginx'])
{'slave': False}
>>> local.cmd('*','service.start',['nginx'])
{'slave': True}
>>> local.cmd('*','service.status',['nginx'])
{'slave': True}
