If I have correctly understood your question, you have a website already running on your server and you would like to install GitStack on the side. I think there are two ways to do it, a hard way and an easy way.

The hard way: You will try add and configure the web application on your existing apache installation. You can get some hints on the GitStack developer wiki ( https://github.com/smart-mobile-software/gitstack/wiki/GitStack-Development-environment-setup ). If you succeed, you might struggle to update you existing installation to the next version. If you do not succeed, you might break your current webserver.

The easy way: Make GitStack run on the port 8080 instead of the port 80. You have to edit the file : C:\GitStack\apache\conf\httpd.conf and replace :
Listen 80 by Listen 8080. Then restart GitStack from the services panel.

We should add an option in the future to let the user choose the port number.

I strongly advise that you create a Windows Restore Point before making any change to your system.

I have tried to reinstall GitStack, but Apache is not installed correctly and no service is created, even if the former installation was unistalled and the remaining directory removed. A total show stopper :(

Hello Erling,

Could you create a ticket on : https://github.com/smart-mobile-software/gitstack/issues?direction=desc&labels=&milestone=&page=1&sort=created&state=open with the exact scenario to reproduce the bug (steps, operating system, etc.) ?

Thank you.

GitStack 1.3 is now friendly with other Apache installations. This solution now works with GitStack 1.3 :
Edit of the file C:\GitStack\apache\conf\httpd.conf and replace : Listen 80 by Listen 8080.
Then restart GitStack from the services panel.
