Method Four

The method is as follows: 1, turn off the MySQL service/etc/init.d/mysqld stop 2, use the –skip-grant-tables option to start the MySQL service, you can modify the/etc/inin.d/mysqld script startup location to add this option, VI/ Etc/init.d/mysqld
The method is as follows:

1, turn off MySQL service
/etc/init.d/mysqld stop

2, using the –skip-grant-tables option to start the MySQL service, you can modify the/etc/inin.d/mysqld script startup location to add this option,
Vi/etc/init.d/mysqld

Add--skip-grant-tables in the following statement to run the startup
/usr/bin/mysqld_safe--skip-grant-tables--datadir= "$datadir"--socket= "$socketfile"
--log-error= "$errlogfile"--pid-file= "$mypidfile"

Adding--skip-grant-tables means skipping permission table authentication when you start the MySQL service. After booting, the root of the connection to MySQL does not require a password

3, restart the MySQL service
/etc/init.d/mysqld start

4. Change the password of root user;

mysql> Update Mysql.user Set Password=password (' 123456 ') where user=root;
mysql> flush Privileges;
Mysql> quit

5. Restart MySQL, you can log in with the new password.

Mysql

Mysql-u root–p
Enter Password: 123456

6, turn off MySQL service
/etc/init.d/mysqld stop

7, modify the 2nd step of the modified/etc/init.d/mysqld, so that it remains the same, that is, cancel the--skip-grant-tables statement
8, restart the MySQL service

/etc/init.d/mysqld start
