[SOLVED] Apache start error

[youaredoome0]

When i enter sudo apache2ctl start, after having shut down the server, i get the following error:
httpd not running, trying to start
(13): make_sock: could not bind to address [::]:80
no listening sockets available, shutting down
Unable to open logs
Apache apparently does not start after this message.

[astrotech226]

There are some other things you are missing without using the init scripts. What happens if you try to start it up this way after rebooting?

sudo /etc/init.d/apache2 start

[youaredoome0]

I get the same error message(s) plus a red [Fail] message.

[astrotech226]

Hmm... What about this:

apache2ctl configtest

[MJN]

You might also want to see if anything else is already listening on port 80 (as the error message suggests something is) with sudo lsof -i :80

Mathew

[youaredoome0]

Tried configtest, it says the config is fine.
When I tried lsof, it just went to the next terminal line, and didn't display anything.
Is there another command I could try to check this?

[faulkes]

Check /var/log/apache2/error_log as well as /var/log/messages for any additional indications as to why the server isn't able to start.

Faulkes

[MJN]

Has it ever worked?

What do you mean by 'having shut down the server'? The web server? The server? Assuming the former, was Apache running beforehand?

So many questions, but we really need more info to go on.

Mathew

[youaredoome0]

Apache was running, but my changes to the config had no effect. I stopped the server using sudo apache2ctl stop and I got those errors when I tried to use sudo apache2ctl start.
The server worked after the initial installation, but every Apache restart attempt has failed.

[MJN]

Ah okay.

It might not make any difference but, as Astroweb says, you really ought to be using the init.d scripts (i.e. sudo /etc/init.d/apache2 start|stop|restart) as not only do these scripts sometimes perform additional sanity checks/controls but they are the standard way of controlling services hence are a good practice to get into across the board.

What happens when you try sudo /etc/init.d/apache2 stop (... then start)? Quite possibly no difference, but let's at least be using a common base.

Mathew

[youaredoome0]

I don't see anything in the error logs that's different.
I tried using the init.d scripts, got the same result.
There may be some problem with port binding, maybe I'll look for stuff on port binding.

[MJN]

Just noticed the IPv6 reference in the error. It is trying to bind to an IPv6 socket and failing, however we shouldn't even be trying (unless you're using IPv6 which I suspect you're not)

Can you post your config? In particular, the NameVirtualHost directive may need setting to *:80 (without any [] brackets the * means only IPv4 addresses, 80 is obviously port 80).

Mathew

[youaredoome0]

I'm confused. The main config file is apache2.conf and there is another file called /sites-available/default. NameVirtualHost is in the default file, ServerName is used in the same file, having something to do with virtual hosts, but when i was getting Could not determine the server's fully qualified domain name, using 127.0.1.1 for ServerName in the error message, putting a ServerName in the apache2.conf fixed it.

[MJN]

This is just how Debian/Ubuntu split the configuration - it resides in multiple files but is all collated into one by various Include directives in the 'master' file /etc/apache2/apache2.conf. You are meant to use this latter file for server-wide configuration, and the files in sites-available/ for more specific config for each site that you host.

What is your NameVirtualHost directive set to? Post your site config (sites-available/default) if you're not sure.

apache2.conf:
# Based upon the NCSA server configuration files originally by Rob McCool.

# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation
# (available at <URL:http://www.apache.org/docs/mod/core.html#lockfile>);

ServerRoot "/etc/apache2"

# The LockFile directive sets the path to the lockfile used when Apache
# is compiled with either USE_FCNTL_SERIALIZED_ACCEPT or
# USE_FLOCK_SERIALIZED_ACCEPT. This directive should normally be left at
# its default value. The main reason for changing it is if the logs
# directory is NFS mounted, since the lockfile MUST BE STORED ON A LOCAL
# DISK. The PID of the main server process is automatically appended to
# the filename.

LockFile /var/lock/apache2/accept.lock

# PidFile: The file in which the server should record its process
# identification number when it starts.

# We recommend you leave this number high, for maximum performance.

This file is symlinked into sites-enabled.
The webserver worked before, but when I tried to restart it, it stopped working. Is it possible that the port is somehow tied to a process no longer running? How would I check this?

[MJN]

Where did that Listen *:80 directive come from? Did you put it in? What do you have in /etc/apache2/ports.conf? (it should already have the listening ports defined, and hence repeating it here will cause exactly this problem)

Mathew

P.S. Hide your e-mail address listed in the config - you don't want it being scraped off this site by a spambot.

The ports file just says Listen 80, should I remove the Listen from default?

[MJN]

Yes.

It now works. Thank you all.
