Ubuntu Linux: Disable Apparmor For Specific Profile / Service Such As Mysqld Server

AppArmor is a security framework for Linux that allows administrators to specify the permissions that applications and services have on the system. To disable AppArmor for a specific profile or service, such as the mysqld server, you can follow these steps:

1. Determine the name of the AppArmor profile for the mysqld service. You can do this by running the following command:

sudo aa-status

This will display a list of the AppArmor profiles that are currently loaded on the system. Look for the mysqld service in the list and note the name of the corresponding AppArmor profile.

2. Disable the AppArmor profile for the mysqld service by running the following command:

sudo aa-disable mysqld

Replace mysqld with the name of the AppArmor profile for the mysqld service that you determined in step 1.

This will disable the AppArmor profile for the mysqld service.

3. Restart the mysqld service to apply the changes. You can do this by running the following command:

sudo systemctl restart mysqld

The AppArmor profile for the mysqld service should now be disabled.

Keep in mind that disabling the AppArmor profile for a service can potentially compromise the security of the system. It is recommended to carefully consider the consequences of disabling AppArmor before doing so.

For more information on AppArmor and how to manage AppArmor profiles on Ubuntu Linux, you can refer to the Ubuntu documentation or the man pages for the aa-status and aa-disable commands.
