ISPConfig3 502 Bad Gateway

Just follow the installation tutorial from beginning to end. For Debian 9, the tutorial is: https://www.howtoforge.com/tutorial...-9-stretch-apache-bind-dovecot-ispconfig-3-1/

The tutorial installs the latest version automatically, which is 3.1.13p1 as of today.

 

Please read the tutorial again:

https://www.howtoforge.com/tutorial...-stretch-apache-bind-dovecot-ispconfig-3-1/3/

it nowhere states that you should run ./install.sh. The tutorial says to run:

php -q install.php

 

Why do you use sudo? Do you see sudo anywhere in the Debian tutorial? Come on, is it so complicated to simply copy/paste commands from a tutorial to your shell window one after another?

 

What is so complicated in following a copy/paste tutorial one step after another? The things you posted as errors today were no commands from the guide, so I have no Idea what you are doing. I can only say that you nowhere do what is written in the install docs as the commands you executed are not in that tutorial. And in case you used the guide, then you must have left many steps out from the tutorial because beside using sudo (which is nowhere mentioned), you must have missed installing PHP before you start the ispconfig installer, but PHP is clearly installed in step 10 of the tutorial, so you can not have run the commands from step 10 if php is missing in step 21 and all the chapters before chapter 21 are required too.

I posted you the link to the install guide several times now:

You start with an empty and clean Debian 9 server. The tutorial as 21 steps (chapters) on 3 pages. You start with chapter 1 on page 1:

https://www.howtoforge.com/tutorial...-9-stretch-apache-bind-dovecot-ispconfig-3-1/

and follow it until the end. Then you do everything that is shown on page 2:

https://www.howtoforge.com/tutorial...-stretch-apache-bind-dovecot-ispconfig-3-1/2/

and finally you do all the steps on page 3:

https://www.howtoforge.com/tutorial...-stretch-apache-bind-dovecot-ispconfig-3-1/3/

But maybe it's not the right thing for you to use Linux or administrate a hosting server. Server administration means that you are responsible for that system and when you even fail to copy/paste commands to install it (or type them in instead), then Linux server management might not be the right thing for you in general or you should start with a smaller setup e.g. install a small LAMP system and practice basic Linux commands first.

 

You start at the beginning, of course, like in any tutorial that you would use to install something. See my post #41, I'll cite:

 

Works fine here. maybe a problem of your server to connect to the package server. Try it again and if it still fails, then check if you block any outgoing connections in s firewall in front of the server.

 

The server must be able to connecdt via http and https to apscatalog.com
