xampp not able to start it's apache service

[abhijit_mohanta]

I need to run another instance (apart from xampp) of apache on my system.
When I m starting xampp with port changed(changed httpd.conf to listen on different port).
I am getting error "another instance of httpd daemon" running.How should I start xampp.

I've looked for some solutions to your problem, unfortunately they require you to build your own Apache/PHP from source. Since the few methods I've read are slightly different, I suggest Googling it and look for the way that suits your needs best.

Although I'm not certain why you would need multiple instances of apache running, a band-aid fix could be to setup a Virtual Machine (Like Virtual Box) and install a (CLI) linux distro and run your secondary web server from that. It's probably not too helpful if you need both servers up all the time, it's just a suggestion.

I'm guessing you've already installed the other instance of Apache, correct?

Try stopping it, which you should be able to do using apache2ctl stop.
Then start XAMPP, which should be /opt/lampp/lampp start.

If XAMPP starts without any problems, check to see if you can access it via http://localhost/ .
If so, somewhere you've missed setting the ports correctly, because it's still accessing it on port 80.

Otherwise, you should have to enter http://localhost:1234/ , with 1234 being the new port number you specified.
If this works and port 80 didn't, I'm not sure what would be conflicting, because in theory it should work.

I haven't ever tried running two Apache servers simultaneously, so that's about all I can think for it to be.

If you need a page to be available on a different port, you might aught to look into configuring a VirtualHost in your settings file to listen on the other port instead of trying to run another instance of Apache.

You can have an Apache server that listens on multiple ports and based on what port the traffic comes in on, you can tell it what page to display. This would make more sense, unless you have a specific reason for doing it the way you're trying to do it.

I was struggling with this despite having changed the settings in httpd.conf and everywhere I could find reference to port 80, xampp still refused to start up with the "another daemon" message. I then did the obvious thing and looked at the ./lampp start up script. It contains a test to see if the port is in use before starting Apache and the test is hardcoded to port 80. So it doesn't matter what you change on the config, lampp will not start.

Simply edit the lampp startup script. The testport call is round line 191 change the port number from 80 to your desired port number and away you go.
