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.
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):
UPDATE mysql.user SET Password=PASSWORD('NEW_PASSWORD') WHERE User='root'; FLUSH PRIVILEGES;
Stop the MariaDB server:
$ sudo /opt/bitnami/ctlscript.sh 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 &
$ sudo /opt/bitnami/ctlscript.sh restart mariadb
Remove the init script:
$ rm /tmp/mysql-init
