Here’s a quick guide on how to migrate from MySQL to MariaDB:
1. Back up your data: This protects you from data loss in case something goes wrong. Use the standard `mysqldump` tool to create a backup of your database.
```
mysqldump -u [username] -p [database_name] > backup.sql
```
1. Install MariaDB: You can install MariaDB server from MariaDB’s official website. Choose the right version for your operating system and follow the installation instructions.
1. Stop MySQL Server: This action depends on your operating system. If you’re using a Unix-like environment, use the command:
\`\`\`
/etc/init.d/mysql stop
\`\`\`
For a system using systemd you can try:
\`\`\`
systemctl stop mysql
\`\`\`
The exact command can vary based on your specific system configuration.
1. Uninstall MySQL: Uninstalling your current version of MySQL server is usually not necessary as MariaDB is “drop-in” replacement, which means it should work without needing to remove MySQL. However, if you want to start fresh, you can uninstall MySQL.
1. Start MariaDB Server: Starting the MariaDB server typically uses the same commands as starting the MySQL server:
\`\`\`
/etc/init.d/mariadb start
\`\`\`
or
\`\`\`
systemctl start mariadb
\`\`\`
1. Load the backup data: Use the MySQL client (which should now be MariaDB) to load the backup data:
\`\`\`
mysql -u [username] -p [database\_name] < backup.sql
\`\`\`
After this procedure, your previous MySQL database should be fully functioning with MariaDB.
Remember to always modify `[username]` and `[database_name]` with your actual data.
Keep in mind that while MariaDB is designed to be a drop-in replacement for MySQL, there may still be minor differences based on specific configurations or versions. Always test your application thoroughly after the migration to make sure everything works as expected. Always perform these actions on Test environment before moving to production.
