MySQL login password forgot the solution

MySQL login password forget, in fact, the solution is very simple, just need to add a line "skip authorization Table" parameter selection in MySQL main configuration file my.cnf!

Add the following line in MY.CNF:
[Email protected] ~]# VIM/ETC/MY.CNF
........
Skip-grant-tables //Skip Authorization Form

Then restart the MySQL service, you can login without password
[Email protected] ~]#/etc/init.d/mysqld restart

Reset Password After login
[[email protected] ~]# MySQL
Mysql> select Host,user,password from Mysql.user;
+--------------------+------+-------------------------------------------+
| Host | user | password |

Comment The line that you added in My.cnf again, and then restart MySQL
[Email protected] ~]# VIM/ETC/MY.CNF
........
#skip-grant-tables

[Email protected] ~]#/etc/init.d/mysqld restart

[Email protected] ~]# mysql-p123456

MySQL login error is as follows:
[Email protected] ~]# mysql-p123456
ERROR 2002 (HY000): Can ' t connect to local MySQL server through socket '/var/lib/mysql/mysql.sock ' (111)

[[email protected] ~]# ps-ef|grep MySQL

The current Mysql.sock file path is/usr/local/mysql/var/mysql.sock,

Workaround: Do a soft link
[Email protected] ~]# Ll/usr/local/mysql/var/mysql.sock
Rwxrwxrwx. 1 mysql mysql 0 Nov 12:55/usr/local/mysql/var/mysql.sock
[Email protected] ~]# rm-f/var/lib/mysql/mysql.sock
[Email protected] ~]# ln-s/usr/local/mysql/var/mysql.sock/var/lib/mysql/mysql.sock

That would be fine.
[Email protected] ~]# mysql-p123456
