Apache2 says no sockets available

[segner]

I'm trying to get Apache2 running. When I start it I get this error:

no listening sockets available, shutting down
Unable to open logs

I've done a lot of searching and can't find much. Most people seem to get this message in conjunction with error 98 (Address already in use....) But what is especially bothersome to me is that it did work briefly and stopped without me changing the config files. I figure some other process must be the culprit, but I don't know how to find out what.

Any ideas?

Thanks

This usually happens when Apache is already running and possibly crashed. The result being that there is a dud process holding onto port 80.

Investigate with 'ps -e' and kill all running instances of httpd, then try to run it again:
$ sudo ps -e
$ sudo killall httpd

'Hope that helps!

Thanks for the help. Unfortunately there weren't any httpd processes to be killed. Furthermore, I get the error no matter what port I tell Apache to listen to.

Apache now runs as 'apache2' so that's what you need to be checking for.

You are attempting to start it as root?

Check the output of sudo lsof -i :<port> where <port> is the port you're using (presumably 80) - this will show if anything else is already listening on it.

I take it from the wording in your post that it's never worked?

Thanks Matthew,

Yes, I am attempting to start it as root. Here is the command and result:

$ sudo /etc/init.d/apache2 start
* Starting web server apache2 no listening sockets available, shutting down
Unable to open logs

I checked the output of sudo lsof -i:80. It doesn't print anything.

No, Apache2 did start several times and served the page I was tinkering with for a short time. Since being restarted it has always failed.

Post your Apache config (apache2.conf) and all files in /etc/apache2/sites-enabled/ and we can take a look.

If you could elaborate on this 'tinkering' it may also help! ;)

hmm.... usually that errors means something is sharing the port 80.
This is probably irrelevant, but have you installed apache and apache2 together? however, lsof -i should have said something... yea, configs would be nice to look at.

So what I'm trying to do is make a webpage with some TV shows on it available to my local network so that the Wii can play them. I had it working briefly. While I was messing with the filetypes that I wanted the videos in and showing it off to my buddy it stopped working.

When it was working the ServerName may have been SegnerOne, which is the name of my computer or it could have been my IP address, I can't remember. Both names produce the same error now, though. The config files are pretty much the defaults.

Thanks,

John

I figured it out. I had accidentally removed the Listen directive. oops.
