在引导阶段进行或禁用mysql自动升级

我发现mysql总是在启动阶段尝试自动升级：

sudo journalctl -b -l | grep  mysql

我每次都会显示mysql在os引导阶段尝试采取的所有行动，mysql尝试升级但失败，现在轮到我解决问题了，哪一个是最好的--在引导阶段创建或禁用mysql自动升级？如何帮助mysql自动升级？

您最好的方法是让

root

用户使用

unix\u socket

身份验证进行打包，这样它就可以安全地进行更新

ALTER USER root@localhost IDENTIFIED VIA unix_socket

如果需要root用户，您可以作为unix root用户运行

mysql

，并进行身份验证。对于日常管理，创建您自己的用户

CREATE USER showkey@localhost IDENTIFIED VIA unix_socket

参考：

或使用密码：

CREATE USER showkey@localhost IDENTIFIED VIA mysql_native_password USING PASSWORD('pwd') 

然后向该用户授予：

 GRANT ALL ON *.* TO showkey@localhost WITH GRANT OPTION

在我的电脑上尝试了这两种方法。 创建新用户是没有用的

CREATE USER showkey@localhost IDENTIFIED VIA unix_socket
GRANT ALL ON *.* TO showkey@localhost WITH GRANT OPTION

问题仍然存在，引导日志与以前相同，可能是因为在引导时使用root执行了自动升级脚本，它与新创建的用户

showkey

这是使mysql成为unix根用户并通过身份验证的正确方法

CREATE USER showkey@localhost IDENIFIED VIA unix_socket

重新启动我的电脑，然后检查引导日志

sudo journalctl -b |grep   mysql

在

CREATE USER中丢失showkey@localhost通过unix_套接字识别
