Requirements :-

  1. Need sudo access on Linux system.

Instructions :-

Step 1 : Stop Currently Running MySQL Service

First thing that we need to stop running MySQL service

sudo service mysql stop

Step 2: Creating The Required Directory

create a /var/run/mysqld directory to be used by MySQL process to store and access socket file

sudo mkdir -p /var/run/mysqld

sudo chown mysql:mysql /var/run/mysqld

Step 3: Manually Start MySQL Service

In this method, you stop the server and start it by specifying –skip-grant-tables, which will not load the grant tables. You can connect to the server as root without a password and set the password.

Since the server runs without grants, it is possible for users from other networks to connect to the server. So –skip-grant-tables automatically enables –skip-networking, which does not allow remote connections

sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &

Step 4: Take MySQL Databases Access Without Password

mysql> USE mysql; 

Reading table information for completion of table and column names

Database changed

mysql> UPDATE user SET authentication_string=PASSWORD("********") WHERE User='root';

Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 1

mysql> UPDATE user SET plugin="mysql_native_password" WHERE User='root';

Query OK, 0 rows affected (0.01 sec)
Rows matched: 1  Changed: 0  Warnings: 0

mysql> quit

Step 6: Kill The MySQL Service

After updating root password we need to kill that MySQL process (which is started by us).

sudo pkill mysqld

Step 7: Start MySQL Service

Start the MySQL service using following command

sudo service mysql start

Step 8: Login With New Password

Login to MySQL server with new password of root user.

mysql -uroot -p********
