02 . SaltStack高级用法(Python API)

/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'}

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

>>> local.cmd('*','cmd.run',['hostname'])
{'slave': 'slave'}
>>> local.cmd('*','cmd.run',['ifconfig'])
{'slave': 'ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500\n        inet 192.168.43.234  netmask 255.255.255.0  broadcast 192.168.43.255\n        ether 00:0c:29:92:1c:db  txqueuelen 1000  (Ethernet)\n        RX packets 57041  bytes 70741421 (67.4 MiB)\n        RX errors 0  dropped 0  overruns 0  frame 0\n        TX packets 39561  bytes 4756727 (4.5 MiB)\n        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0\n\nlo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536\n        inet 127.0.0.1  netmask 255.0.0.0\n        loop  txqueuelen 1  (Local Loopback)\n        RX packets 4  bytes 340 (340.0 B)\n        RX errors 0  dropped 0  overruns 0  frame 0\n        TX packets 4  bytes 340 (340.0 B)\n        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0'}
>>> local.cmd('*','cmd.run',['crontab -l'])
{'slave': 'no crontab for root'}
>>> local.cmd('*','cmd.run',['df -h'])

>>> 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}
