apache error (probably mine)
 
OK, I'll humble myself. Its probably a PEBKAC error, but this is what I'm getting when trying to load Apache2. (first time setting up a server)

Code:

(13): make_sock: could not bind to address [::]:80
no listening sockets available, shutting down
Unable to open logs

How do I fix it?

vdhussa 12-03-2007 12:50 AM

Can you post your config file. What address have you bound apache to? Also check if the user from which apache is launched has the required permissions

j-ray 12-03-2007 02:15 AM

did you start it as root? if not do so.The default socket is bound to port 80 and so needs root privileges to be created. If you change the config file to make the apache listen on port 8080 i. e. you can start it as normal user...

Anvil 12-03-2007 02:32 AM

.. also, you might want to check that there isn't already an instance running that's blocking the port.

ps -ef | fgrep httpd

is it possible that apache is trying to bond to ipv4 address and ipv6 - but the server doesn't have ipv6 enabled ??

also run netstat -ntl to see what tcp ports are currently being listened on

the couldn't open logs does however imply a permissions problem

phantom_cyph 12-03-2007 04:47 PM

Running in root, I get this:

Quote:

phantom@lightseeker:~$ sudo apache2
(98): make_sock: could not bind to address [::]:80
no listening sockets available, shutting down
Unable to open logs
phantom@lightseeker:~$

or...
Quote:

phantom@lightseeker:~$ netstat -ntl

Took care of that part...

Now, I'm getting more errors.

Code:

phantom@lightseeker:/etc/apache2$ sudo apache2
Syntax error on line 54 of /etc/apache2/httpd.conf:
Cannot load /etc/apache2/mods-available/actions.load into server: /etc/apache2/mods-available/actions.load: invalid ELF header
phantom@lightseeker:/etc/apache2$

Here is my httpd.conf file (a friend's with a few mods, which i haven't finished cause it won't load my initial ones).

Code:

#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned. 
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/httpd/foo.log"
# with ServerRoot set to "@@ServerRoot@@" will be interpreted by the
# server as "@@ServerRoot@@//var/log/httpd/foo.log".

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to point the LockFile directive
# at a local disk.  If you wish to share the same ServerRoot for multiple
# httpd daemons, you will need to change at least LockFile and PidFile.
#
ServerRoot "/etc/apache2"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen *:80

Ahaah :) Something's already got IPV6 port 80.

Now try (as root)
netstat -nap | fgrep ":80"

This will reveal what app has port 80 open.
