XAMPP won't start Apache on Mac OS X 10.10.3 Yosemite

Question

I had a local XAMPP stack running on my Macbook Pro fine for weeks (OS X Yosemite 10.10.3, XAMPP 5.5.24). Then, I spent some time trying to install a library, in which I somehow messed up the installation of XAMPP. Now Apache does not start up at all anymore. This is what I tried.

Start up Apache

$ sudo /Applications/XAMPP/xamppfiles/xampp startapache
XAMPP: Starting Apache...fail.
XAMPP:  Another web server is already running.

$ sudo /Applications/XAMPP/xamppfiles/xampp stopapache
XAMPP: Stopping Apache...not running.

So I try to find which web server is already running.

Zombie apaches

I check for zombie apaches.

$ sudo lsof | grep AMP | grep apache
$ ps -x | grep apache
 7980 ttys000    0:00.00 grep apache
$ ps -x | grep AMP
 7990 ttys000    0:00.00 grep AMP

So I don't see any webserver running.

Skype

I close Skype. Still the same problem.

Other listeners on port 80

I checked for other listeners on port 80, as suggested in mnfc's answer.

Kill other listeners on port 80

I wanted to kill the existing httpd processes. I first closed all other applications, including Firefox. When I try to kill them using sudo killall httpd or sudo kill 1227, they don't disappear. I still cannot start my Apache server then.

Complete fresh installation

I uninstalled XAMPP completely, removed the directory, and reinstalled XAMPP from the installation package. I rebooted my Macbook. Still the same problem.

XAMPP Manager OS X

Where can I find these logs? If they are the files in `/Applications/XAMPP/logs`, they are all empty. — physicalattraction, May 04 '15 at 06:20

After months of trying, I finally got it working. I found the solution here: disable OSX's built-in Apache server.

sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist

You should check for other processes bound on a TCP socket to port 80.

netstat -atp tcp | grep -i "listen"

Achive Internet connections (including servers)

While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes. – Fazer87 Apr 30 '15 at 14:52
Spot on. The reason we ask that you include relevant information is that the Apple SO page you linked to could be deleted, changed, spammed/deformed.. which would not only kill that answer, but yours too. Also, you now get recognition for making effort insteaf of just being smart enough to copy/paste :) – Fazer87 Apr 30 '15 at 15:00
You mean i now get recognition because i actually did copy/paste :D sorry for OT though – mnfc12 Apr 30 '15 at 15:06
Thanks for the answer. I indeed had checked that already, but forgot to mention that in my post. I have added it now. Unfortunately, that did not give me any clue for a process that is blocking my Apache server. :-( – physicalattraction May 04 '15 at 06:17
There is something, which listen. See line: tcp46 0 0 *.http *.* LISTEN – Romeo Ninov May 04 '15 at 06:23
It's as Romeo Ninov said. Now find out which process is listening: lsof -i -P | grep -i "listen" – mnfc12 May 04 '15 at 11:41
I find it hard to understand the output of lsof, see my original post. Should I look at this line: `Dropbox 281 erwin 27u IPv4 0x45f774a12399b65b 0t0 TCP *:17500 (LISTEN)`? – physicalattraction May 04 '15 at 12:31
that's not the line we're looking for. What's the output of this: `lsof -i :80` – mnfc12 May 04 '15 at 14:34
I have added the output in the OP. Again, I don't really understand the output of that command. – physicalattraction May 05 '15 at 06:54
The important part we were looking for is in columns 6, 7, 8 (TCP *:80 LISTEN). If we found a match we could identify the process by its PID/command. According to your netstat output there's already a process listening on TCP port 80 (http). `tcp46 0 0 *.http *.* LISTEN ` Since we didn't find the process we were looking for in that output, i guess the process does not belong to your user. Try running it as root. `sudo lsof -i -P | grep -i "listen"` The output i'm expecting should look like this `root 12u IPv4 0x45f774a12399b65b 0t0 TCP *:80 (LISTEN)` – mnfc12 May 05 '15 at 09:59
First of all: @mnfc12, thanks for your trouble! Really appreciate it. I indeed find now a listener: `httpd`. I have added the output in the OP. This seems to be the exact web server that I am trying to start up! How could this process still be running, even after I completely removed XAMPP and restarted my computer? – physicalattraction May 05 '15 at 15:38
This must be another httpd executable that's launched on startup. At this point I'm not sure how to track down the program on Mac OS since I use Linux. [How do I get the full path...](http://stackoverflow.com/questions/14805896/how-do-i-get-the-full-path-for-a-process-on-os-x/14805977#14805977) If you know its location you, you might be able to find out when/why you've installed it on your machine. However you can also just skip this part, kill the process by its id and start xampp. This is no clean solution but since you should only use XAMPP for testing anyway, it could be sufficient. – mnfc12 May 06 '15 at 10:50
I tried to kill the processes, but they come back by itself. I still cannot start the Apache webserver. – physicalattraction May 27 '15 at 09:45
Have a look in `System Preference`s anything related to `Web Sharing`... disable this and it may stop the `httpd` service that keeps respawning – Kinnectus May 27 '15 at 09:52
I don't find `web sharing`, I do find `internet sharing`. That is already disabled, like all other `sharing` options. – physicalattraction May 27 '15 at 12:32

for anyone looking for an answer to start any server on Xamps(Been digging on this for way too long).

Do it via the terminal: I found this link definitely helped:

http://daplo.net/solved-mac-os-x-xampp-mysql-server-is-not-starting/

mysql-sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

Apache- sudo /Applications/XAMPP/xamppfiles/bin/ftpdctl start

Hope that helps.

Cheers

This is a tangential answer to OP's question, which was about Apache not starting. I would also be surprised if `ftpdctl` started Apache... – bertieb Mar 29 '17 at 14:06
