Modify the default MariaDB administrator password

NOTE: We are in the process of modifying the configuration for many Bitnami stacks. On account of these changes, the file paths and commands stated in this guide may change depending on whether your Bitnami stack uses MySQL or MariaDB. To identify which database server is used in your stack, run the command below:

 $ test -d /opt/bitnami/mariadb && echo "MariaDB" || echo "MySQL"

The output of the command indicates which database server (MySQL or MariaDB) is used by the installation, and will allow you to identify which guides to follow in our documentation for common database-related operations.

Change the MariaDB root password

You can modify the MariaDB password using the following command at the shell prompt:

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

Reset the MariaDB root password

NOTE: Depending on the version you have installed, you may find the MariaDB files at /opt/bitnami/mysql

If you don’t remember your MariaDB 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):

    • For versions lower than 10.4:

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

    • For version 10.4 and higher:

        ALTER USER root@'%' IDENTIFIED VIA mysql_native_password USING PASSWORD("NEW_PASSWORD");
  FLUSH PRIVILEGES;

  • Stop the MariaDB server:

      $ sudo /opt/bitnami/ctlscript.sh stop mariadb

  • Start MariaDB with the following command:

      $ sudo /opt/bitnami/mariadb/bin/mysqld_safe --defaults-file=/opt/bitnami/mariadb/conf/my.cnf --init-file=/tmp/mysql-init 2> /dev/null &

  • Restart MariaDB:

      $ sudo /opt/bitnami/ctlscript.sh restart mariadb

  • Remove the init script:

      $ rm /tmp/mysql-init
