    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
    8 2015-11-23 23:30:15,136 [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
    9  

    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。
