Default skip-grant-tables:非常有用的mysql启动参数

介绍一个非常有用的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。有什么用呢?当然是忘记管理员密码后有用。
操作方法:
1、杀掉原来进行着的mysql:
rcmysqld stop
或者:
service mysql stop
或者:
kill -TERM mysqld
2、以命令行参数启动mysql:
/usr/bin/mysqld_safe --skip-grant-tables &
3、修改管理员密码:
use mysql;
update user set password=password('yournewpasswordhere') where user='root';
flush privileges;
exit;
4、杀死mysql,重启mysql
