How to secure MySQL?
Here are some tips for securing your MySQL server.
- Set the Root password and delete the test database: in CentOS/RedHat run the command
- Review your current MySQL users and remove unused credentials.
- Using Passwords directly in the CLI, this shows on the process list and in shell history.
- When adding MySQL users try not to use wildcards for hostname values.
