密码忘记修改

1.

2．修改MySQL的登录设置： 
# 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 
保存并且退出vi。

3．重新启动mysqld 
# service mysqld restart 
Stopping MySQL: [ OK ] 
Starting MySQL: [ OK ]

4．登录并修改MySQL的root密码 
# 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 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

2.

set password for root@localhost = password(‘123456‘);

如果报错需要先执行

flush privileges;

 

 

mysql 全目录可执行

 ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql

如果换用户无法访问，检查有无访问链接路径的权限
