Salt Master报错:Minion did not return. [No response]

在salt master端执行salt ‘*’ test.ping时，某一节点出现如下报错：
Minion did not return. [No response]

登陆到这一节点查看minion的日志，发现如下的问题：

1 $ tail -f /var/log/salt/minion
2 The master may need to be updated if it is a version of Salt lower than 2015.5.3, or
3 If you are confident that you are connecting to a valid Salt Master, then remove the master public key and restart the Salt Minion.
4 The master public key can be found at:
5 /etc/salt/pki/minion/minion_master.pub
6 2015-11-23 23:30:02,645 [salt.crypt                               ][ERROR   ][3530] The Salt Master has cached the public key for this node, this salt minion will wait for 10 seconds before attempting to re-authenticate
7 2015-11-23 23:30:05,108 [salt.crypt                               ][ERROR   ][3586] The Salt Master has cached the public key for this node, this salt minion will wait for 10 seconds before attempting to re-authenticate

minion大概的意思就是，minion端拿到的key与master端的不符，验证无法通过。
解决方法是删除minion端的key，再重新与master进行连接和认证。

 1 $ cat pki/minion/minion_master.pub 
 2 -----BEGIN PUBLIC KEY-----
 3 MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAtzq0AjuyQsVEgsx692GN
 4 ... ...
 5 7fbuudp4yu5vcYcqksKIFcm0J3E+OR+rx/NUIHt0ZL8HLxcSn4Si/S6dVp/vE7Oc
 6 swIDAQAB
 7 -----END PUBLIC KEY-----
 8 [root@localhost salt]# rm -fr pki/minion/minion_master.pub
 9 
10 [root@localhost salt]# service salt-minion restart
11 Stopping salt-minion daemon:                               [  OK  ]
12 Starting salt-minion daemon:                               [  OK  ]
13 salt-key -A　　　　　　##重新加载key

至此，master与minion端的通信正常。
