# Change Password

# Change MySQL root password in Linux

To change MySQL's root user password:

Step 1: Stop the MySQL server.

  • in Ubuntu or Debian:
    `sudo /etc/init.d/mysql stop`
  • in CentOS, Fedora or Red Hat Enterprise Linux:
    `sudo /etc/init.d/mysqld stop`
  • Step 2: Start the MySQL server without the privilege system.

    sudo mysqld_safe --skip-grant-tables &

    or, if mysqld_safe is unavailable,

    sudo mysqld --skip-grant-tables &

    Step 3: Connect to the MySQL server.

    mysql -u root

    Step 4: Set a new password for root user.

    ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
    SET PASSWORD FOR 'root'@'localhost' = PASSWORD('new_password');

    Note: The ALTER USER syntax was introduced in MySQL 5.7.6.

    Step 5: Restart the MySQL server.

  • in Ubuntu or Debian:
    `sudo /etc/init.d/mysql stop`
    `sudo /etc/init.d/mysql start`
  • in CentOS, Fedora or Red Hat Enterprise Linux:
    `sudo /etc/init.d/mysqld stop`
    `sudo /etc/init.d/mysqld start`
  • # Change MySQL root password in Windows

    When we want to change root password in windows, We need to follow following steps :

    Step 1 : Start your Command Prompt by using any of below method :

    Perss Crtl+R or Goto Start Menu > Run and then type cmd and hit enter

    Step 2 : Change your directory to where MYSQL is installed, In my case it's

    C:\> cd C:\mysql\bin

    Step 3 : Now we need to start mysql command prompt

    C:\mysql\bin> mysql -u root mysql

    Step 4 : Fire query to change root password

    mysql> SET PASSWORD FOR root@localhost=PASSWORD('my_new_password');

    # Process

    1. Stop the MySQL (mysqld) server/daemon process.
    2. Start the MySQL server process the --skip-grant-tables option so that it will not prompt for a password: mysqld_safe --skip-grant-tables &
    3. Connect to the MySQL server as the root user: mysql -u root
    4. Change password:
    • (5.7.6 and newer): ALTER USER 'root'@'localhost' IDENTIFIED BY 'new-password';
    • (5.7.5 and older, or MariaDB): SET PASSWORD FOR 'root'@'localhost' = PASSWORD('new-password); flush privileges; quit;
    1. Restart the MySQL server.

    Note: this will work only if you are physically on the same server.
