Modify the MySQL administrator password

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/ 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/ --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/ --datadir=/opt/bitnami/mysql/data --init-file=/tmp/mysql-init 2> /dev/null &
  • Restart the MySQL server:

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

    $ rm /tmp/mysql-init
