salt-minion关于以下公钥无法验证错误的处理备忘

1. 进入调试模式: salt-minion -l debug
[DEBUG   ] Reading configuration from /etc/salt/minion
[DEBUG   ] Configuration file path: /etc/salt/minion
[INFO    ] Setting up the Salt Minion "本机主机名"
[DEBUG   ] Created pidfile: /var/run/salt-minion.pid

[DEBUG   ] Loaded minion key: /etc/salt/pki/minion/minion.pem
[CRITICAL] The Salt Master has rejected this minion's public key!
To repair this issue, delete the public key for this minion on the Salt Master and restart this minion.
Or restart the Salt Master in open mode to clean out the keys. The Salt Minion will now exit.

2.删除 /etc/salt/minion配置文件在重启调试模式

3. 再次更改/etc/salt/minion中的master id后解决。
