mysql查看并修改初始密码

Posted 2023-02-15 Java小周

查看初始密码：

grep 'temporary password'  /var/log/mysqld.log

修改初始密码：

SET PASSWORD = PASSWORD('123456');

ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;

flush privileges;

如修改不了，可修改密码策略：

set global validate_password.policy=0;  #设置为弱口令
set global validate_password.length=1;  #密码最小长度为1

开启远程访问权限

use mysql;

select host,user from user;

update user set host = '%' where user = 'root';

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';

flush privileges;
