Step-by-Step Guide
1 Install MySQL
Install MySQL using your package manager. On Ubuntu use apt install mysql-server. The service starts automatically after installation.
Pro Tips:
- Note the temporary root password if generated
- MySQL 8.0 uses caching_sha2_password by default
2 Secure the Installation
Run mysql_secure_installation immediately after install. This sets root password, removes test database, and disables remote root login.
Pro Tips:
- Use strong root password
- Keep root access local only
3 Create Databases and Users
Create a separate database and user for each application. Grant only necessary privileges using GRANT statements.
Pro Tips:
- Never use root for applications
- Use GRANT . WITH GRANT OPTION sparingly
4 Configure for Production
Tune innodb_buffer_pool_size, enable slow query log, and set up automated backups using mysqldump or Percona XtraBackup.
Pro Tips:
- Set buffer pool to 70-80% of available RAM
- Test your backup restoration process
