Question 1

How do I install MariaDB on a VPS?

Accepted Answer

On Ubuntu/Debian: "sudo apt install mariadb-server". Run "sudo mysql_secure_installation" for initial security setup. MariaDB is a drop-in MySQL replacement - existing MySQL applications work without changes.

Question 2

Is MariaDB better than MySQL?

Accepted Answer

MariaDB offers better performance in many benchmarks, more storage engines, and is truly open-source. MySQL has more enterprise features. For most web applications, they perform identically. MariaDB is the default in many Linux distributions.

Question 3

Can I migrate from MySQL to MariaDB?

Accepted Answer

Yes, MariaDB is binary-compatible with MySQL. You can usually stop MySQL, install MariaDB, and start it with existing data files. For safety, export with mysqldump and import into MariaDB. Most applications work without code changes.

Question 4

How do I optimize MariaDB for small VPS?

Accepted Answer

Set innodb_buffer_pool_size to 128-256MB, reduce max_connections to 50-100, disable performance_schema, and configure key_buffer_size for MyISAM tables. These settings work well for 1-2GB RAM instances.
