If everything goes well, then you should see the following output: mysql -u root -p Enter password: Welcome to the MySQL monitor. If you have not set a password for the user root, do not use the parameter ‘-p’. If your MySQL or MariaDB server has set a password, then you call the program as follows: Copy mysql -u root -p Once you are logged in to your server, you simply use mysql-binary to login. If you have not yet created a new user who has the rights to create new databases, use the user ‘root’. If you are logged on to the server, you can simply log on to your MySQL or MariaDB server.

Relational databases (MySQL, PostgreSQL, Oracle and similar), and so-called non-relational databases, also called no-SQL databases. There are actually only two large areas of databases.

It takes caching work off the database, which is vital for scaling to a larger number of logged-in users. Object Cache provides an alternative caching backend. Because the database also handles many queries for normal page requests, it is the most common bottleneck causing increased load-times. Most website frameworks like Drupal and WordPress use the database to cache internal application objects which can be expensive to generate (menu trees, filter results, etc.), and to keep cached page content.
