Hello to everybody, ISPConfig 3.x developer confirmed to me in this thread that there is no way for CentOS 7 to integrate ruby into ISPConfig. https://www.howtoforge.com/community/threads/centos-7-how-to-ruby-in-ispconfig-3-x.82012/ Anyone please have some functional instructions on how to support ruby on CentOS 7? Any alternative in the form of passenger and puma for apache? I can also pay a small amount of thanks for the instructions. Thank you all for your reactions.
