Modify the default MariaDB administrator password

NOTE: We are in the process of modifying the file structure and configuration for many Bitnami stacks. On account of these changes, the file paths stated in this guide may change depending on whether your Bitnami stack uses native Linux system packages (Approach A), or if it is a self-contained installation (Approach B). To identify your Bitnami installation type and what approach to follow, run the command below:

 $ test ! -f "/opt/bitnami/common/bin/openssl" && echo "Approach A: Using system packages." || echo "Approach B: Self-contained installation."

The output of the command indicates which approach (A or B) is used by the installation, and will allow you to identify the paths, configuration and commands to use in this guide. Refer to the FAQ for more information on these changes.

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';
    • For version 10.4 and higher:

        ALTER USER root@'%' IDENTIFIED VIA mysql_native_password USING PASSWORD("NEW_PASSWORD");
  • Stop the MariaDB server:

      $ sudo /opt/bitnami/ stop mariadb
  • Start MariaDB with the following command:

    • For Bitnami installations following Approach A (using Linux system packages):

        $ sudo /opt/bitnami/mariadb/bin/mysqld_safe --defaults-file=/opt/bitnami/mariadb/conf/my.cnf --init-file=/tmp/mysql-init 2> /dev/null &
    • For Bitnami installations following Approach B (self-contained installations):

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

      $ sudo /opt/bitnami/ restart mariadb
  • Remove the init script:

      $ rm /tmp/mysql-init
