今天在接收一台MySQL服务器的时候发现忘记MySQL的root用户的密码,查找资料发了各种文档里面也没有root用户密码,因此需要修改root用户密码。首先确认服务器出于安全的状态,也就是没有人能够任意地连接MySQL数据库。因为在重新设置MySQL的root密码的期间,MySQL数据库完全出于没有密码保护的状态下,其他的用户也可以任意地登录和修改MySQL的信息。最安全的状态是到服务器的Console上面操作,并且拔掉网线。1、修改MySQL的登录设置: 在[mysqld]的段中加上的skip-grant-tables # sed -i "/mysqld/askip-grant-tables " /etc/my.cnf2、重新启动mysqld # service mysqld restart Shutting down MySQL. SUCCESS! Starting MySQL. SUCCESS!3、登录并修改MySQL的root密码 # /usr/bin/mysql Welcome to the MySQL monitor. Commands end with ; or g.
