mysql 恢复用户

Posted 2021-02-04

[[email protected] ~]# systemctl stop mysqld
[[email protected] ~]# mysqld_safe --skip-grant-table & #跳过授权表，直接就可以登录mysql
注：一个非常有用的mysql启动参数—— --skip-grant-tables。顾名思义，就是在启动
mysql时不启动grant-tables，授权表 --skip-networking是不让别的用户远程登陆
[[email protected] scripts]# mysql #登录MySQL
#往mysql库的user表中插入root用户
mysql> grant all on . to [email protected]‘localhost‘; #这条命令不需要执行，直接执行下面的命令
mysql> flush privileges;

在数据库里执行，把以下的内容粘贴复制进去
insert into mysql.user values (‘localhost‘,‘root‘,PASSWORD(‘123‘),
‘Y‘,
‘Y‘,
