Question

Apache Bind problems - Will 'Listen 80' but not to specific IPs, how to bind to specific IPs?

Asked by: bill78uk

Hello!
I am trying to bind my Apache2 to specific IP addresses. Currently in the apache conf I have:

Listen 80
and then in my virtual hosts config I have:

NameVirtualHost 80.xx.xx.15:80
NameVirtualHost 80.xx.xx.17:80

<VirtualHost 80.xx.xx.15:80>


When I change the Listen part to :

Listen 80.xx.xx.15:80
Listen 80.xx.xx.17:80


Shutdown the server, check that nothing is running on port 80, and restart I get the error message:

(98)Address already in use: make_sock: could not bind to address 80.xx.xx.15:80 no listening sockets

and Apache exits. I have no other Listen's elsewhere in the code (I do have a ServerName outside of the Virtualhost, if that makes a difference?). I change it back to Listen 80 and it works again no problem! I'm limited to experiment too much, as it's a live server.

What could be the problem? Please help!

Hi, Apache2 is running on Debian.  The /sbin/ip addr command doesnt work, but the contents of /etc/network/interfaces is:

==========================

auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 80.xx.xx.14
        netmask 255.255.255.0
        network 80.xx.xx.0
        broadcast 80.xx.xx.255
        gateway 80.xx.xx.1
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 80.xx.xx.20
        dns-search xx.co.uk

iface lo:1 inet static
        address 80.xx.xx.15
        netmask 255.255.255.255

iface lo:2 inet static
        address 80.xx.xx.16
        netmask 255.255.255.255

iface lo:3 inet static
        address 80.xx.xx.17
        netmask 255.255.255.255

==========================

I have been successfully using the IP addresses for VirtualHosts for the last year, so the machine is responding to those IPs.  Is there something more I have to do to bind them specifically?

 

by: samriPosted on 2007-10-04 at 14:51:00ID: 20018197

Assuming that all interfaces are up and running (80.xx.xx.14,15,16,17):

Try to do "ping" to all the configured IP address and make sure it is alive.

Then

the directive

Listen 80
NameVirtualHost *:80

should be sufficient.

You have it backwards; this is how we do it in our web farm for hundreds for virtual hosts:

Listen xx.xxx.xxx.xxx:80
Listen xx.xxx.xxx.xxx:8080

then vhosts sections are in the format:

<VirtualHost *:80 *:8080>
ServerName my.domain.com
 ####otherstuff
</VirtualHost>
