Fix XAMPP Apache Not Starting Because Port 80 In Use

by 2014-11-26 Blog Comments

xampp apache serverThe most common cause for the XAMPP Apache server not starting issue is because the default port no 80 may already be in use by another program like Skype, Teamviewer etc.  For example, in my previous blog post with the solution for XAMPP and Windows User Account Control warning message issue, Mr. Shankar Paul said his new XAMPP Apache was not working. He had got the below message from XAMPP which says the Port 80 in use by another program.

Solutions 1: Stop Conflicting Program And Start XAMPP Apache Server

If you carefully read this XAMPP message, you’ll see they give a solution – to uninstall/disable or reconfigure the blocking program. For example most common programs for Apache not starting is Skype. If that is the case quit/stop Skype and run Apache and see. I have also heard other programs like Teamviewer, Microsoft Internet Server etc. also use port 80 and block Apache from starting.

However this is not best solution. If today one program is blocking Apache from starting up, tomorrow another program (or even a service like windows web publishing service etc.) can use the same port and block Apache from running.

Solutions 2: Change Default Port 80,443 of XAMPP Apache Server

So, the best solution like EL.Web.ID and Geethika says, is to reconfigure the XAMPP Apache server to listen and use different port numbers. Here is how you do it:

1) First, you need to open the Apache “httpd.conf” file and configure it to use/listen on a new port no.

setup xampp apache
To open httpd.conf file, click the “Config” button next to Apache “Start” and “Admin” buttons. In the popup menu that opens, click and open httpd.conf

2) Within the httpd.conf file search for “listen”. You’ll find two rows with something like;

#Listen 12.34.56.78:80
Listen 80

Change the port no to a port no. of your choice (e.g. port 1234) like below

#Listen 12.34.56.78:1234
Listen 1234

3) Next, in the same httpd.conf file look for “ServerName localhost:” Set it to the new port no.

ServerName localhost:1234

4) Save and close the httpd.conf file.

5) Now click the Apache config button again and open the “httpd-ssl.conf” file.

6) In the httpd-ssl.conf file, look for “Listen” again. You may find:

Listen 443

Change it to listen on a new port no of your choice. Say like:

Listen 1443

7) In the same httpd-ssl.conf file find another line that says, “<VirtualHost _default_:443>”. Change this to your new port no. (like 1443)

7) Also in the same httpd-ssl.conf you can find another line defining the port no. For that look for “ServerName”. you might find something like:

ServerName www.example.com:443 or  ServerName localhost:433

Change this ServerName to your new port no.

8) Save and close the httpd-ssl.conf file.

9) Finally, there’s just one more place you should change the port no. For that, click and open the “Config” button of your XAMPP Control Panel. Then click the, “Service and Port Settings” button. Within it, click the “Apache” tab and enter and save the new port nos in the “main port” and “SSL port” boxes. Click save and close the config boxes.

That should do the trick. Now “Start” Apache and if everything goes well, your Apache server should start up.

You will also see the Apache Port/s no in the XAMPP control panel has change to the new port IDs you set 🙂

Using XAMPP Apache Server After Port No. Change

If you follow solution 2 and change the Apache port no, you will have to append the new port number to the URL when you connect to the Apache server. For example, previously if you typed localhost, you will now have to type localhost:1234.

    1. Hi Piravinthb, d
      Did you get a “port in use” error message before? Because this solutions is for if you get the “port 80 in use” kind of error message. If you get no error messages then it can be due to any no of problems. If you can post more details about your situation and how you arrived at this point then maybe I or another reader here can help you.

  12. This worked great! But for some reason can’t get phpMyAdmin to work now? I keep getting a #2002 error? Do I have to change anything with this or MySQL now that I changed the localhost path for Apache?

    1. Hi Mohammad,
      If XAMPP is not working tryout installing WAMP server. WAMP package files download size is only 38 MP so much smaller than XAMPP but can do the same development work like php systems, wordpress theme dev etc. But note you might encounter the same error. So before installing quit skype, teamviewer or any other software that might be use the port 80.

  151. I can get to my xampp folder on localhost, but when I try to access any other directory I have within my htdocs folder, there’s some sort of redirect taking place: so I type: localhost:1337/mydirectory, and get redirected to: localhost/mydirectory (without the port number).. which then obviously gives me nothing but a blank screen…

  153. Hi Aksam,
    Great remedy, Thank you so much.
    I have changed only my httpd.config to port 8080 in Listen and localhost lines as you suggest and everything works fine with Bitmani under Windows 10. Have NOT changed http-ssl.config and Service Setting which remain 80 and 443 respectively. Using Apache 2.4.
    I do have one concern though; could this cause an issue when uploading my website to remote host server?

    Thanks in advance,
    Rob

  165. The best way to solve this problem is:

    1. Open a CMD prompt and type in command: net stop was /y

    2. Run Dialog Box (press keys Win+R) .. then type: services.msc

    3. Scroll down to: World Wide Web Publishing Service Double click on it and click STOP (if this service status is Started)

    4.Start Apache again with XAMPP 🙂
