Mysql5.7如何修改root密码_MySQL

May 27, 2016 pm 01:45 PM

版本更新,原来user里的password字段已经变更为authentication_string

版本更新 缘故,好多网上的教程都不适用了,甚至连官网的文档也不是能够顺利操作的。

如果 MySQL 正在运行,首先杀之:


killall -TERM mysqld。
Copy after login


运行


mysqld_safe --skip-grant-tables &
Copy after login


如果此时不想被远程连接:


mysqld_safe --skip-grant-tables --skip-networking &
Copy after login


使用mysql连接server

更改密码:


update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';
Copy after login


*特别提醒注意的一点是,新版的mysql数据库下的user表中已经没有Password字段了

而是将加密后的用户密码存储于authentication_string字段


mysql> flush privileges;
mysql> quit;
Copy after login


修改完毕。重启


killall -TERM mysqld。
mysqld_safe &
Copy after login


然后mysql就可以连接了

但是此时操作似乎功能不完全,还要alter user...


alter user 'root'@'localhost' identified by '123';
Copy after login


网文说酱紫也可以:

set password for 'root'@'localhost'=password('123');
cp mysql.server /etc/init.d/mysql
chmod +x /etc/init.d/mysql
chkconfig --add mysql
Copy after login
