salt Rosters

salt除了支持Master 和Minion方式之外，还支持SSH; SSH方式因为没有minion主动连接master，所以需要维护 roster，提供master可以操作的对象;roster的配置文件默认在:/etc/sat/roster

[root@linux-node1 ~]# cat /etc/salt/roster
# Sample salt-ssh config file
#web1:
#  host: 192.168.42.1 # The IP addr or DNS hostname
#  user: fred         # Remote executions will be executed as user fred
#  passwd: foobarbaz  # The password to use for login, if omitted, keys are used
#  sudo: True         # Whether to sudo to root, not enabled by default
#web2:
#  host: 192.168.42.2

linux-node1.oldboyedu.com:
  host: 192.168.74.20
  port: 22
  user: root

linux-node2.oldboyedu.com:
  host: 192.168.74.32
  port: 22
  user: root
# priv: /root/.ssh/id_rsa

如果在roster的配置文件中没有写入私钥文件或者密码,第一次操作的时候，需要写入密码

[root@linux-node1 ~]# salt-ssh '*' test.ping  -i

之后就可以正常操作了

[root@linux-node1 ~]# salt-ssh '*' test.ping
linux-node1.oldboyedu.com:
    True
linux-node2.oldboyedu.com:
    True
[root@linux-node1 ~]# salt-ssh '*' cmd.run 'uptime'

[root@linux-node1 ~]# salt-ssh '*' state.sls salt.init_repo   #和salt的操作相同
