通过 cat /var/log/mysqld.log | grep password 命令查看数据库的密码

通过 mysql -uroot -p 敲回车键进入数据库登陆界面

通过 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root'; 命令来修改密码

通过 exit; 命令退出 MySQL，然后通过新密码再次登陆

.通过以下命令，进行远程访问的授权

createuser'root'@'%'identifiedwithmysql_native_passwordby'root';grantallprivilegeson*.*to'root'@'%'withgrantoption;flushprivileges;

通过 ALTER USER 'root'@'localhost' IDENTIFIED BY 'root' PASSWORD EXPIRE NEVER;

命令修改加密规则，MySql8.0 版本 和 5.0 的加密规则不一样，而现在的可视化工具只支持旧的加密方式。

通过 flush privileges; 命令刷新修该后的权限

通过以下命令，关闭 firewall(防火墙）

systemctlstopfirewalld.service;systemctldisablefirewalld.service;systemctlmaskfirewalld.service;
