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

1. 查看minion端的日志信息
[root@iZbp150ikdomqe3b32qaubZ salt]# cat /var/log/salt/minion

[root@iZbp150ikdomqe3b32qaubZ salt]# systemctl restart salt-minion.service
[root@iZbp150ikdomqe3b32qaubZ salt]# cat /var/log/salt/minion 
2018-05-26 18:03:22,963 [salt.utils       ][ERROR   ][21937] DNS lookup of 'salt' failed.
2018-05-26 18:03:22,963 [salt.minion      ][ERROR   ][21937] Master hostname: 'salt' not found. Retrying in 30 seconds

2018-05-26 18:07:23,176 [salt.minion      ][ERROR   ][21937] Master hostname: 'salt' not found. Retrying in 30 seconds
2018-05-26 18:07:30,020 [salt.crypt       ][ERROR   ][22002] The Salt Master has cached the public key for this node, this salt minion will wait for 10 seconds before attempting to re-authenticate

根据报错信息分析：
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。

2. 删除minion端的salt-master秘钥信息
[root@salt-slave-node1 minion]# pwd
/etc/salt/pki/minion
[root@salt-slave-node1 minion]# ls
minion_master.pub  minion.pem  minion.pub
[root@salt-slave-node1 minion]# rm -rf minion_master.pub 

3. 重新验证秘钥测试
[root@iZwz9bhan5nqzh979qokrkZ pki]# salt-key -L
