How can I forget the root password of mysql in linux?

1. First confirm that the server is in a secure state, that is, no one can connect to the MySQL database at will. Because during the resetting of the MySQL root Password, the MySQL database is completely out of the password-free status, other users can also log on and modify the MySQL information at will. You can use MySQL to disable External ports and stop Apache and all user processes to achieve quasi-security of the server. The safest status is to operate on the server Console and unplug the network cable.

2. Modify MySQL Logon Settings:

# vi /etc/my.cnf 

In the [mysqld] section, add skip-grant-tables.
For example:

[mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock skip-grant-tables 

3. Restart mysqld

# /etc/init.d/mysqld restart Stopping MySQL: [ OK ] Starting MySQL: [ OK ] 

4. log on to and modify the MySQL root Password

# /usr/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 

5. Modify the MySQL Logon Settings.

# vi /etc/my.cnf 

Delete the skip-grant-tables added to the [mysqld] section.

6. Restart mysqld

# /etc/init.d/mysqld restart Stopping MySQL: [ OK ] Starting MySQL: [ OK ]
