saltstack（master迁移）

环境：http://www.cnblogs.com/zzzhfo/p/6126223.html

在添加一台master

把master的/etc/salt目录下的pki打包 上传至第二台master的/etc/salt目录下；然后修改minion端/etc/hosts 把salt 指向新的master、重启服务。

• 打包文件

[[email protected] salt]# tar -czf pki.tar.gz pki
[[email protected]-server salt]# ls
master  pki  pki.tar.gz
使用lrzsz下载到本地
[[email protected]-server salt]# sz pki.tar.gz 

新的master主机操作
使用lrzsz上传到/etc/salt下
[[email protected]-server02 salt]# rz
[[email protected]-server02 salt]# tar -xzf pki.tar.gz
[[email protected]-server02 salt]# /etc/init.d/salt-master start
Starting salt-master daemon:

• 修改minion的hosts

[[email protected] salt]# salt ‘*‘ cmd.run ‘grep salt /etc/hosts‘
salt-client-02:
    192.168.119.132   salt
salt-minion-01:
    192.168.119.132   salt
[[email protected]-server salt]# salt ‘*‘ cmd.run "sed -i ‘s#132#129#‘ /etc/hosts"      #改为新的master的IP
salt-client-02:
salt-minion-01:
[[email protected]-server salt]# salt ‘*‘ cmd.run ‘grep salt /etc/hosts‘
salt-client-02:
    192.168.119.129   salt
salt-minion-01:
    192.168.119.129   salt

• 重启服务

[[email protected] salt]# salt ‘*‘ service.restart salt-minion
salt-minion-01:
    True
salt-client-02:
    True

查看minion服务是否正常

[[email protected]02 /]# ps -ef | grep salt
root      1459     1  0 08:36 ?        00:00:00 /usr/bin/python2.6 /usr/bin/salt-minion -d
root      1464  1154  0 08:36 pts/0    00:00:00 grep salt
[[email protected]-minion-01 /]# ps -ef | grep salt
root      1418     1  1 01:27 ?        00:00:00 /usr/bin/python2.6 /usr/bin/salt-minion -d
root      1423  1176  0 01:27 pts/1    00:00:00 grep salt

在新的master主机上测试

[[email protected] salt]# salt ‘*‘ test.ping
salt-client-02:
    True
salt-minion-01:
    True
