我在撒盐小爪时遇到一些错误：
Error while bringing up minion for multi-master. Is master at salt-server00001.nix.us.companyworld.company.com responding?
2019-10-16 11:57:27,935 [salt.minion ][ERROR ][34679] Error while bringing up minion for multi-master. Is master at usazrcncm10286.nix.us.kworld.kpmg.com responding?
2019-10-16 11:57:37,990 [salt.crypt ][ERROR ][34679] The masters sent its public-key signature, but signature verification is not enabled on the minion. Either enable signature verification on the minion or disable signing the public key on the master!
2019-10-16 11:57:37,990 [salt.crypt ][CRITICAL][34679] The Salt Master server's public key did not authenticate!
The master may need to be updated if it is a version of Salt lower than 2017.7.2, or
If you are confident that you are connecting to a valid Salt Master, then remove the master public key and restart the Salt Minion.
我没有设置多主机。
我已经接受了盐主服务器上服务器的密钥。
我已经打开了防火墙上的盐端口。
但是盐服务器仍然没有响应。
这是我的盐版本报告：

为什么我会看到此问题以及如何解决？
答案 0 :(得分：2)
在/var/log/salt/minion
然后，发出salt '*' service.status并检查主服务器是否正在运行。
检查盐主服务systemctl status salt-master
在我的情况下，盐大师无法启动：

尝试使用systemctl start salt-master重新启动服务。
如果错误仍然存在，请在主服务器上运行netstat -lnp，然后查看Salt端口是否在那里并正在监听。
就我而言，一段时间后，我重新发出了启动salt-master服务的命令，该服务联机：
