Modify the default MariaDB administrator 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

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
