Linux下恢复MySQL管理员密码

1、向mysqld server 发送kill命令关掉mysqld server(不是 kill -9),存放进程ID的文件通常在MYSQL的数据库所在的目录/var/lib/mysql中。

# killall -TERM mysqld

2、使用--skip-grant-tables参数来启动 mysqld。

# /usr/bin/safe_mysqld --skip-grant-tables

路径不一定都一样，可以用locate找一下。
3、然后就可以无密码登录到mysqld server ，此时Mysql的密码和刚安装时一样，，都是为空。现在我们可以使用mysqladmin来改变mysql的密码了。

#mysqladmin -u root -p password newpassword

4、载入权限表，使用下面的命令

# mysqladmin flush-privileges

linux
