Hi
I am using fedora 11. i am getting following error while starting the apache. there is not virtual host. I am using the main apache server. My systems networking is fine. Samba and other applications are working fine.


# apachectl -t
[Thu Aug 13 17:22:01 2009] [crit] (22)Invalid argument: alloc_listener: failed to get a socket for (null)
Syntax error on line 134 of /etc/httpd/conf/httpd.conf:
Listen setup failed


Help!

You have a syntax error on line 134 of /etc/httpd/conf/httpd.conf .

Sorry but i am not a novice in Apache. 132 line in apapche's httpd.conf is

Listen 80

i tried both configuration like

Listen IP:80
Listen 80

it gives same error.

Having the same issue on a new Fedora 11 instance on Rackspace's cloud server. Any solutions?

It says 134 but you gave us 132?

I'm having the exact same issue using slicehost if you have a solution let me know I'll be sure to post mines if I find out.

This error occurs in the APR support library when the httpd process attempts to create a socket. The source is:

svn.apache.org/repos/asf/httpd/httpd/tags/2.1.8/server/listen.c

It appears that the APR library that is current on Fedora 11 is not compatible with the httpd release.

Here is the initial configuration I had, which was producing the error:

httpd-2.2.11-8.i586
httpd-tools-2.2.11-8.i586
httpd-devel-2.2.11-8.i586
apr-util-1.3.9-1.fc11.i586
apr-util-devel-1.3.9-1.fc11.i586
apr-devel-1.3.8-1.fc11.i586
apr-util-ldap-1.3.9-1.fc11.i586
apr-1.3.8-1.fc11.i586

It is possible to use yum to downgrade:

yum downgrade apr apr-util -y
yum install httpd -y

This leaves the following packages installed:

httpd-tools-2.2.11-8.i586
httpd-2.2.11-8.i586
apr-util-ldap-1.3.9-1.fc11.i586
apr-1.3.3-4.fc11.i586
apr-util-1.3.9-1.fc11.i586

Apache httpd will now start.

Installing the development libraries, such as apr-devel or httpd-devel, will undo this, and return it to a non-working installation. There appears to be some dependency issues here.

If you need the development libraries, here's an approach that seems to work:

yum install apr apr-util apr-devel apr-util-devel apr-util-ldap -y
yum downgrade apr apr-util apr-devel apr-util-devel apr-util-ldap -y
yum install httpd-devel -y

Thank for your reply . i have already done these things...........

Hmm - didn't work for me either...

Found this on another Forum - seems to work...

Fedora has pushed out a new version of APR that fixes the issue. You have to enable the testing repo to update it properly.

The fix is in comment #10 at this link:
