Change the database password

MySQL

If your database is running in a Docker container, log into it by running:

docker exec -it <container_id> bash

Enter the MySQL CLI by running:

mysql -u<root_mysql_user> -p<old_password>

To change the password for MySQL 5.7 and above, run:

mysql> SET PASSWORD FOR 'root' = PASSWORD('new_password');
mysql> FLUSH PRIVILEGES;

To change the password for older versions (before 5.7), run:

mysql> ALTER USER '<mysql_user>'@'localhost' IDENTIFIED BY '<mysql_password>';
mysql> FLUSH PRIVILEGES;

PostgreSQL

If your database is running in a Docker container, log into it by running:

docker exec -it <container_id> bash

Once inside the container, change the password with:

psql --user <postgresql_user>
\password
\q
