Upgrading MySQL/MariaDB with Governor (cPanel's database management system) over multiple versions can be a complex process that requires careful planning and execution. Here's a step-by-step guide to help you through the process:
Note: Before you start, make sure to take a backup of your databases and configurations to avoid any data loss in case something goes wrong.
-
Review System Requirements:
- Make sure your server meets the requirements for the target MySQL/MariaDB versions.
-
Check Compatibility:
- Verify that your applications and scripts are compatible with the target MySQL/MariaDB versions.
-
Check Release Notes:
- Review the release notes for each version you plan to upgrade through. Look for any special considerations or steps required for each version.
-
Upgrade Path:
- Identify the upgrade path. For example, if you're upgrading from MySQL 5.6 to MySQL 8.0, you'll need to go through intermediary versions like 5.7 first.
-
Backup Databases:
- Take a complete backup of all your databases using tools like
mysqldump
or cPanel's backup features.
- Take a complete backup of all your databases using tools like
-
Backup Configuration Files:
- Make copies of important configuration files like
my.cnf
for MySQL ormy.cnf.d/server.cnf
for MariaDB.
- Make copies of important configuration files like
-
Upgrade MySQL/MariaDB:
-
Begin the upgrade process from the oldest version to the newest. For example, if you're upgrading from MySQL 5.6 to MySQL 8.0, follow these steps: a. Upgrade from MySQL 5.6 to MySQL 5.7. b. Upgrade from MySQL 5.7 to MySQL 8.0.
-
For MariaDB, follow a similar process based on your current version and the target version.
-
-
Update System Packages:
- Ensure that your system's package manager is up to date.
-
Update cPanel/WHM:
- If you're using cPanel/WHM, make sure it's updated to the latest version that supports the target MySQL/MariaDB version.
-
Verify Services:
- After each upgrade, verify that MySQL/MariaDB services start correctly and that your applications and websites are working as expected.
-
Check for Incompatibilities:
- Test your applications and scripts to make sure they work properly with the new MySQL/MariaDB version. Some functions and queries may behave differently.
-
Reconfigure:
- Review and, if necessary, adjust your configuration files (e.g.,
my.cnf
) to accommodate any changes introduced in the new MySQL/MariaDB versions.
- Review and, if necessary, adjust your configuration files (e.g.,
-
Monitor Performance:
- Keep an eye on server performance and monitor for any unusual behavior or resource consumption.
-
Security Considerations:
- Review and update your security configurations to account for any changes or new features introduced in the upgraded versions.
-
Documentation and Cleanup:
- Document the upgrade process and any configuration changes made. Clean up any temporary files or backups used during the upgrade process.
-
Final Testing:
- Perform thorough testing to ensure that all applications and services are functioning as expected with the upgraded MySQL/MariaDB version.
Remember that this process can be complex, and it's crucial to proceed with caution. If you're unsure about any step, it's recommended to seek assistance from a qualified server administrator or cPanel support.
