Modify the MySQL administrator password

Change the MySQL root password

NOTE: When setting a new password, avoid the use of special characters or quotes, as this can sometimes cause issues when accessing the database through shell scripts.

You can modify the MySQL password using the following command at the shell prompt. Replace the NEW_PASSWORD placeholder with the actual password you wish to set.

$ /opt/bitnami/mysql/bin/mysqladmin -p -u root password NEW_PASSWORD

Reset the MySQL root password

If you don’t remember your MySQL root password, you can follow the steps below to reset it to a new value:

  • Create a file in /tmp/mysql-init with the content shown below (replace NEW_PASSWORD with the password you wish to use).

    If your stack ships MySQL v5.7.x or MySQL v8.x, use this content:


    If your stack ships MySQL v5.6.x or earlier, use this content:

    UPDATE mysql.user SET Password=PASSWORD('NEW_PASSWORD') WHERE User='root';

    TIP: Check the MySQL version with the command /opt/bitnami/mysql/bin/mysqladmin --version or /opt/bitnami/mysql/bin/mysqld --version

  • Stop the MySQL server:

    $ sudo /opt/bitnami/ctlscript.sh stop mysql
  • Start MySQL with the following command:

    If your stack ships MySQL v8.x, use this command:

    $ sudo /opt/bitnami/mysql/bin/mysqld_safe --pid-file=/opt/bitnami/mysql/data/mysqld.pid --datadir=/opt/bitnami/mysql/data --init-file=/tmp/mysql-init --lower_case_table_names=1 2> /dev/null &

    If your stack ships an older version of MySQL, use this command:

    $ sudo /opt/bitnami/mysql/bin/mysqld_safe --pid-file=/opt/bitnami/mysql/data/mysqld.pid --datadir=/opt/bitnami/mysql/data --init-file=/tmp/mysql-init 2> /dev/null &
  • Restart the MySQL server:

    $ sudo /opt/bitnami/ctlscript.sh restart mysql
  • Remove the script:

    $ rm /tmp/mysql-init
