For some quite years I have been managing WEB servers for hosting with the command line. It was driving me crazy, but I haven't found yet a friendly solution. Later, in one of my past jobs, I was introduced to cPanel. It was not a good experience. I can tell that cPanel, first it is not free, it has an easy installer but the way it is though it is not the best for a Linux guy. cPanel (when I tested) bundles its own Apache and other software, so security fixes rely on cPanel guys, not on your distro updates. cPanel web interface is awful, too many ports opened! To find a single option you need to go into many menus as possible.
After a while, I discovered ISPConfig and while testing I started liking it. It uses system RPM's, it can run on a VPS or bare metal box and configurations are very easy to follow. As any management software, installing is not a short or easy task. You can look and you will find long documents on how to configure ISPConfig, you may need to download some source tarballs and compile manually; in order to make this easier for everyone, I have developed these RPMs for Centos 6 and 7, and I have published them for your happiness in the OKay repository. Please read my short guide on how to configure it fast.
And yes, It works in CentOS 6 and 7. Some people still use CentOS 6 for an unknown reason.
Following my guide, you can install ISPConfig in 5 minutes.
FusionPBX has a way to allow authentication with key. This way you will be able to log into your WEB console with a GET parameter. Something like this:
This authentication is very useful when you want to code your own REST API or to have a backdoor.
If you have FusionPBX 4.2, or an early version of 4.4 (before August 2018), the way to enable is as follows:
If you have updated to Fusion 4.4 and your last update is after August 2018, follow these steps:
Next time you add or edit a user, you will find a new field where you can put your key.
