[gentoo-user] Dead apache (cannot listen)

Somewhere in the update to 2.2.4-r12, listening got lost.  I tried to follow
instructions,
but apparently failed.

Here's what happens (minus a MaxClients warning that doesn't look like a
show-stopper):

treat init.d # ./apache2 start
 * Starting apache2 ...
(98)Address already in use: make_sock: could not bind to address
64.166.164.49:80
no listening sockets available, shutting down
Unable to open
logs
[ !! ]
treat init.d #

So it got my instructions to listen, but failed.

Looking at 'netstat --inet -l' does not show any listeners or open sockets
on port 80.

What else should I look at?

you should look at your vhost configs. take an example of the current 
default_vhost config and make sure to keep the -D DEFAULT_VHOST 
in /etc/conf.d/apache2
Ive had the same problem with one of my servers and after using the default 
thiggie it worked fine.

Thanks for top-posting  :o)

This is still a bit mysterious for me.  I've tried to do what you said, but
apache still fails to start because it cannot
open a listening port.  Here's what I've figured out about what I have:
/etc/conf.c/apache2 contains
    APACHE2_OPTS="-D DEFAULT_VHOST -D INFO -D LANGUAGE -D MANUAL -D SSL -D
SSL_DEFAULT_VHOST -D USERDIR"
to which I contributed only USERDIR -- the other stuff came with the
ebuild.  Maybe I should drop the SSL stuff since my server has
no https stuff (It does have htaccess and htpasswd stuff, but I think that's
different).  In any event, removing the SSL stuff does not change
the problem.

Everything else in that file is commented out, which I take to mean that
default values are used.  Among the defaults is
#CONFIGFILE=/etc/apache2/httpd.conf
and that file contains
   Include /etc/apache2/vhosts.d/*.conf
      And /etc/apache2/vhosts.d/  includes
         00_default_ssl_vhost.conf    and   00_default_vhost.conf

My 00_default_vhost.conf:

Thats not a vhost configuration, so it's a bit confusing why your trying 
to use Gentoo's default vhost config file and making non vhost configs 
and I bet it isn't liking the missing:

NameVirtualHost *:80 (You will have to check the apache2 doc for the 
VirtualIP version of NameVirtualHost)

<VirtualHost *:80>

If you want to make a non vhost configuration, then do so from the 
ground up, don't mix vhost and non vhost unless you want a mess.

The reason you get :80 already bound, is because your configuration bind 
twice to the same IP. It's Apache itself that bind twice and bails on 
the second attempt.

Not having used this configuration layout in years, I would guess 
ServerName is the one creating the listening socket, maybe because it's 
placed before Listen.

A workaround has been found (see below).

As may be obvious by now, I don't understand much about configuring apache.
I just used what dropped in when I installed Gentoo around 2003, and tried
to adapt as time and updates came along.  My needs are fairly simple: a
basic server on a single IP plus localhost, using the default port 80.
Static and CGI pages only, no secure applications.  Users (only me,
actually) have a page in public_html.  I intend to use mod_python
eventually, or write my own module, but that's for later.

I have not a clue how to build a configuration "from the ground up", and I'm
hoping to not have to learn.  Since it would be a singleton excercise, I
would just forget it anyway in the midst of many other things that claim my
attention.

Workaround:
In any event, making ServerName come after Listen, or commenting it out
completely, do not change the symptoms at all.  However, commenting out all
Listen lines does allow apache to start.  It seems you're right and apache
is colliding with itself, but I don't know why, as I don't see any other
Listen directives.  This is at best a stopgap because apache's now listening
promiscuously, which I do not like at all.

I'm hoping for more help, but my fallback is to save my config files,
unmerge apache completely, re-emerge it and see if the default configuration
can be made to work right.  That might turn out to be a lot of work, for
which read a lot of time.

I was sure I checked for duplicate Listen directives, but I missed one.
Fixing that allowed apache to start.
As pennance, I hunted down all my tailorings and put them in a single
include file.  In the process I wound
up eliminating a bunch of other duplications.  Hopefully things will be more
sane soon.

But not right away -- but I'll start another thread for that.
