Topic: Multiple Apache servers on on single Linux box redhat

[srinureddy.etta@gmail.com]

Hi
I need to configure multiple Apache Web Servers on redhat server.
I have copied and extracted Apache 2.2 into redhat server and extracted but not able to install because I don't understand setting prefix. Please let me explain about prefix configuration and how to set it. At the same time I would like to know is it possible to setup 4 Apache Web Servers on same machine if possible then how to.
Can we set up different versions of Apache HTTP Servers?


Thanks

Why you need different servers? Can't you use vhosts?

If you have to use different webservers, you can't do that out of the box, you have to compile apache yourself.

[srinureddy.etta@gmail.com]

I need to install because I am setting cluster environment on same machine like two dispatchers for aem and two Web Servers for Weblogic.
Could you let me know how it can be done, I mean any doc or link

[James Blond]

I don't know aem, but for weblogic you can use two vhosts to different backends.

Could you tell me how multiple apache instances are installed on Redhat enterprise linux

[James Blond]

As I said, you have to compile it yourself. http://mariobrandt.de/archives/apache/compling-apache-2-4-on-ubuntu-or-debian-519/

Only change the paths for each installation.

Could you let me know what what paths you are talking about in the post and do i need to make any other changes to start two servers and at the same time does it work for redhat.

Thanks

I talk about --prefix=/opt/apache2 the install path

[srinureddy.etta@gmail.com]

I have compiled and installed the Apache2.4.10 in /opt/apache21 and tried starting the severer using apachectl -k start.
below is the error:

>>Passing arguments to httpd using apachectl is no longer supported.
You can only start/stop/restart httpd using this script.
If you want to pass extra arguments to httpd, edit the
/etc/sysconfig/httpd config file.
AH00548: NameVirtualHost has no effect and will be removed in the next release /etc/httpd/conf/httpd.conf:82
httpd (pid 20028) already running

httpd out of the box i have installed, is that causing the problem?

Please let me know should i remove out of the box installation.

[James Blond]

for apachectl just use

apachectl start
or use
httpd -k start

Remove the line 82 it is no longer needed.

The following is the error

AH00534: httpd: Configuration error: More than one MPM loaded.

[James Blond]

Please post your config at http://apaste.info/ So I can have a look at it.

[srinureddy.etta@gmail.com]

I have submitted please look at it

http://apaste.info/sKR

[James Blond]

Hm, you changed the config at lot.
However I can't see the module you try to load because of

Include conf.modules.d/*.conf

So I think you load there multiple MPMs. Since it is possible to load different MPMs in 2.4

[srinureddy.etta@gmail.com]

What is the problem.
I Have installed Apache using out of the box (yum install httpd) and then compiled and installed.
The second one I am not able to start because it says httpd is already running.

[James Blond]

Do you use the same port and or the same IP?

[srinureddy.etta@gmail.com]

Hi
I am using the same ip but different port.

[James Blond]

if you don't mind, but the acutal error message would help a lot Just copy it from the shell.
