1.修改MySQL的登陆设置:
在[mysqld]的段中加上一句:skip-grant-tables
例如:
[mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock skip-grant-tables
保存而且退出vi。
2.从新启动mysqld
# ./home/mariadb/bin/mysqld restart Stopping MySQL: [ OK ] Starting MySQL: [ OK ]
3.登陆并修改MySQL的root密码
# ./home/mariadb/bin/mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 to server version: 3.23.56 Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql> USE mysql ; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> UPDATE user SET Password = password('new-password') WHERE User = 'root' ; Query OK, 0 rows affected (0.00 sec) Rows matched: 2 Changed: 0 Warnings: 0 mysql> flush privileges ; Query OK, 0 rows affected (0.01 sec) mysql> quit Bye
4.将MySQL的登陆设置修改回来
