mysql 忘記root密碼的解決辦法
1、修改MySQL的登錄設置：
# vim /etc/my.cnf
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
保存並且退出vi。
2、重新啟動mysqld
# service mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]
3、登錄並修改MySQL的root密碼
mysql -uroot -p 按回車直接進入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 ;
Database changed
mysql> UPDATE user SET authentication_string = password ( ‘new-password‘
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
4、將MySQL的登錄設置修改回來
# vim /etc/my.cnf
將剛才在[mysqld]的段中加上的skip-grant-tables刪除
保存並且退出vim
5、重新啟動mysqld
# service mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]
6、使用密碼進行登錄。
