Unable to connect to localhost in browser after installing XAMPP successfully

xampp localhost 12.04 apache2

31,722

According to the output of netstat, the Apache webserver fails to open the listening port. You should download the newest version of XAMPP and follow the instructions on the site.

If XAMPP is ran with default configuration, the output should look something like this:

whisperity@localdomain:~$ sudo netstat -tlnp

I have successfully installed XAMPP 1.5.3 following this guide on Ubuntu 12.04 and it started with no errors.
```
$ sudo /opt/lampp/lampp start

Starting XAMPP for Linux 1.5.3a...
XAMPP: Starting Apache with SSL (and PHP5)...
XAMPP: Starting MySQL...
XAMPP: Starting ProFTPD...
XAMPP for Linux started.
```
But when I open http://localhost/ or http://127.0.0.1/ in Firefox I get the Unable to connect error.

After I turned out to be unsuccessful, I changed the port in httpd.conf as described here from 80 to 81 and attempted to open http://localhost:81/ and http://127.0.0.1:81/, but I got the same result.

Edit

The output of netstat -tlnp:

  Please post the output of sudo netstat -tlnp so we can see the open ports.

  You are using a very old version of xampp its up to version 1.8.0 now.http://localhost should be all thats needed from default web browser

  i realised the oldness of it after i installed (just copy pasted the instructions). i need it to do some quick testing on a web app i'm working on, but if no quick fix is to be found i will try to upgrade and see if that does it. still... i found it to be an issue an just in case it may occur later again, is good to learn a few extra things.

  @user60333 yes, i did test the localhost/xampp/index.php and 127.0.0.1/xampp/index.php

I'm having trouble downloading the latest version (poor connection), and i'm trying another way since that's waht i'm really interested in.

@claudia The problem is with Apache's configuration (that's why the listener daemon does not start) files (/opt/lampp/etc/httpd.conf and /opt/lampp/etc/extra/httpd-*.conf), not PHP.

Welcome to Ask Ubuntu! These appear to be instructions to fix a similar problem on Windows rather than this problem on Ubuntu. If that is not the case, I recommend copy-editing this post for grammar and sentence structure to clarify what exactly you are recommending.
