[数据库]Centos 下 mysql root 密码重置


重置mysql密码的方法有很多,官网也提供了很方便的快捷操作办法,可参考资料 resetting permissions 。本文重置密码的具体步骤如下:

一、停止MySQL(如果处于运行状态)

#service mysqld stop输出Shutting down MySQL.                    [ OK ]

关于 #service mysqld stop 命令,可参考 CENTOS 6.5 平台离线编译安装 Mysql5.6.22。

二、启动MySQL_safe,如此以来便可不用密码登录MySQL

# mysqld_safe --skip-grant-tables &输出类似Starting mysqld daemon with databases from /var/lib/mysqlmysqld_safe[6025]: started

三、登录MYSQL

# mysql -u root输出Welcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 1 to server version: 4.1.15-Debian_1-logType 'help;' or '\h' for help. Type '\c' to clear the buffer.mysql>

 

四、设置新密码

mysql> use mysql;mysql> update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';mysql> flush privileges;mysql> quit

五、停止MySQL

# /etc/init.d/mysql stop输出Stopping MySQL database server: mysqldSTOPPING server from pid file /var/run/mysqld/mysqld.pidmysqld_safe[6186]: ended[1]+ Done          mysqld_safe --skip-grant-tables

六、启动MySQL并测试新密码是否正确

# /etc/init.d/mysql start# mysql -u root -p
