Want to make dealing with SELinux considerably easier? Learn about three semanage commands that will help you accomplish this while not disabling the critical security system in this quick tutorial.

I get it--SELinux is challenging, and when your applications or services are prevented by the security layer, your first inclination is to set it to either Disabled or Permissive. In a time when security is at a premium, you can't afford to make that change, else you risk the security of your entire system or your network. You don't want that.

Instead of putting everything at risk, why not make use of a tool that can help you out? That tool is semanage, which is the SELinux policy management tool. With semanage, you can adjust file contexts, port contexts and booleans, which will go a long way to help you make things workable, while not disabling the security system.
