Hi I want to run multiple instances of apache2 on different ports. Can some one guide me.

You don't want multiple instances of apache, you want multiple virtual servers on different ports. For example (from the above documentation link):

Code:

Listen 80
Listen 8080

NameVirtualHost 172.20.30.40:80
NameVirtualHost 172.20.30.40:8080

<VirtualHost 172.20.30.40:80>
ServerName www.example.com
DocumentRoot /www/domain-80
</VirtualHost>

<VirtualHost 172.20.30.40:8080>
ServerName www.example.com
DocumentRoot /www/domain-8080
</VirtualHost>

<VirtualHost 172.20.30.40:80>
ServerName www.example.org
DocumentRoot /www/otherdomain-80
</VirtualHost>

<VirtualHost 172.20.30.40:8080>
ServerName www.example.org
DocumentRoot /www/otherdomain-8080
</VirtualHost>

Dear Mace,

Thanks for your reply. I am aware of the virtual hosts. The problem here is I am accesing the server on the lan using IP address. Also the need for this is I have different versions of cgi-bins to be run on different ports. I have connecting taomcat server (multiple) to which the requests will be passed based on the port it has been received.

To summarise I need a set up where
1. Multiple tomcats running on different ports
2. Requestes to these is passed by apache.

As all the apps on each of the tomcat is different I need a seperate apache2.

So I am trying to run multiple apaches on different ports whihc will have a one to one realation with tomcats.

Please let me know which is the best way I can take.

Thanks

If virtual hosts are not acceptable, then you need to run virtual systems. The lightest weight and simplest way is UML (User Mode Linux). The more common method these days is via Xen or VMWare.

Dear Mace,

After going through this I felt it may not be necessary to run multiple apaches. I will try to use Virtual hosts and try to fix my problem. As I said earlier I access the machine on IP in LAN. Not very sure how to configure the virtual hosts.

Thanks

What if we want to run multiple instances for different things and didn't want one to affect the other and only have one box? Currently I'm trying to run 2 apache instances but keep having issues regarding:

# /usr/sbin/apache2 -f /etc/apachetmp/apache2.conf -k start
(98)Address already in use: make_sock: could not bind to address 192.168.2.151:80
no listening sockets available, shutting down
Unable to open logs

This currently is not bound to anything as far as I know...the other instance uses .150.

Any ideas?

you can definitely run multiple versions/instances of apache, as long as they're listening on different IP/port. Just make sure the Listen directive has a proper a.b.c.d:e address/port combo, and the DocumentRoot's of the instances serve out different content. I've ran a setup like that (one apache for one ip/dns entry, and another apache for a whole variety of ip-, port-, and name-based vhosts) for over 5yrs and it worked great, first on 1.3.x, then on 2.0.x

Great then you can probably help here:

Do you know why this would occur when using Listen Directive?

WASPDEVDebian01:/etc/apache2# /usr/sbin/apache2 -k start
(98)Address already in use: make_sock: could not bind to address 192.168.2.150:80
no listening sockets available, shutting down
Unable to open logs

Do you know any mods that would prevent this from functioning properly?

Any further assistance you can provide would be greatly appreciated.

Thanks

it's apparently trying to start another instance on teh same ip/port. set the Listen directives to different ip/ports and you will be fine.
