Saltstack认证时出现错误：Minion did not return. [No response]

出现的错误

原因可能有一下

1.master端/etc/salt/pki/minion目录下的minion_master.pub与minion端/etc/salt/pki/minion目录下的minion_master.pub内容不一致

2.minion启动有延时（等十几秒即可）

解决：

1.在minion端把/etc/salt/pki/minion目录下的minion_master.pub删除

rm -rf /etc/salt/pki/minion/minion_master.pub

2.重启salt-minion

systemctl restart salt-minion.service 

3.重启salt-master

systemctl restart salt-master.service 

4.在master端重新认证

salt-key -L
salt-key -A

5.检查

salt '*' test.ping
