MySQL and other popular database servers are notoriously prone to crashes.
But there’s no easy way to restore a database that’s gone down.
Luckily, there’s a lot you can do.1.
Make sure your MySQL database is up-to-date.
If you’re using MySQL 5.5 or newer, you can create a recovery file in the database’s /etc/mysql/restore.conf file.
This file allows you to make changes to the database that might help fix the problem.
The file can be created by following these steps:2.
Start a new database.
Open a terminal window, navigate to the MySQL database directory, and run:3.
Delete the backup files you created in step 2.4.
Restore the database by running the following commands:5.
Create a recovery log.
Start by running:6.
Copy the following into the recovery log:7.
Edit the log with your favorite text editor.
For example, you could use vim or nano.
You can change the name of the file to something more specific.
For instance, you might want to name it recovery.log.
