Mention SELinux Booleans: Save 3 Hours of My Life. #3252

Issue

Many people using this guide (me) will be coming from CentOS 7. If you're installing a LAMP stack, there's a 98% chance you plan to connect to outside APIs from PHP scripts on your website: PayPal, Stripe, etc.

If you follow the guide as published, all those calls will fail with "network error 7". The reason is that you forgot to do this in the section about dealing with SELinux:

setsebool httpd_can_network_connect 1

Without that setting, the httpd process can't establish any outbound connections. Your users will waste three hours trying to figure out why.

Suggested Fix

You should modify the guide to add this to the "Dealing with SELinux" section because this requirement is new on CentOS 8.
