1，建立master端和client端的正常连接

#master
yum -y install  epel-release
yum -y install satl-master
sed -i 's/#auto_aucept： False/auto_accept： True/g' /etc/salt/master
/etc/salt-maser restart


#minion
yum -y install  epel-release
yum -y install satl-master
sed -i 's/salt:  master/salt: 192.168.1.130/g'
/etc/init.d/satl-minion restart

#master
salt-key    # 等待2分钟就有客户端的key过来了
salt '*' test.ping

2，模拟客户端修改主机名

1，minion端停止服务
/etc/init.d/salt-minion stop
2，master端删除对应的key
salt-key -d jack.com      # jack.com 为该 minion端的ID
3，minion端修改主机名
sed  -i 's/HOSTNAME=jack.com/HOSTNAME=tom.com/g' /etc/sysconfig/network
hostname tom.com
4，minion端删除原来的ID
rm -f /etc/salt/minion_id
rm -rf /etc/salt/pki
5,minion端启用服务
/etc/init.d/salt-minion restart
6,master端上查看新接收的ID
salt-key  # 等待2分钟
satl 'tom.com' cmd.run  'hostname'
