[users@httpd] Apache, Jboss and mod_jk
Hello!
I'm trying to find the solution of my problems in Nabble, but my search
isn't good.
I'm working with Jboss 4.2.3.GA, Apache 2.2.9 and mod_jk, everything working
on Fedora 8.
I would like to create a cluster of two computers and a loadbalancer based
on Apache.
I had no problems creating the cluster: my computers communicate and share
applications.
I installed Apache and it works, showing the Test Page.
Then I tried to configure the web server with mod_jk. I downloaded the
binary version of mod_jk and I followed the guide that I found on
http://www.jboss.org/file-access/default/members/jbossas/freezone/docs/Clustering_Guide/beta500/html_single/index.html#clustering-http-modjk
The only thing that I modified on configuration was the names of nodes in
workers.properties (I wrote the ip address of each node).
Therefore, after the configuration, I started Jboss on both machines, then
Apache (which is on one of two computers), then I tried to access to my
application, deployed on both Jboss instances, following the link
http://<ip-address>/application/<name-of-application>
What I see on my browser is a "404 not found" error, because Apache looks
for the application in /var/www/html/<name-of-application>
The same thing happens if I try to access to jmx-console of JBoss.
What I think is that the module mod_jk is not loaded and not working
correctly (in the log folder, mod-jk.log does not appear!)
I even tried to compile the sources of mod_jk and use this version of
module, but it doesn't work and it gives me the same error!
Any comments to help me?
Thanks guys!

Ciao Davide!
My application works on JBoss.
It's a html page which invokes a servlet.
If I try my application visiting http://<ip-address>:8080/<my-application>,
it works!
apachectl configtest returns "Syntax OK" and in error_log file, i can find
only the error "File does not exist", because Apache looks for my
application in /var/www/html, instead forwarding the request to JBoss.

Ok, I found what's wrong!
Following what André said, I looked for other file called "httpd.conf" in my
computer and I found some files under the folder /etc/httpd.
Here there aren't all the files of Apache, but there is the httpd.conf which
is working with Apache.
So I need to modify this file, first of all!
Therefore, my question is: is it normal this way of distributing the
configuration file in different folders?
Why not connecting Apache with the httpd.conf that you can find in the
Apache folder (/usr/apache2/conf)?
I'm sorry if these questions are maybe trivial, but I try to understand! =)
Thanks

Hi André
The version of Apache isn't an Apache "packaged" for Fedora.
I downloaded the .tar.gz version from http://httpd.apache.org and then I
configured and installed it!
The installation created the folder /usr/apache2, specified with the command
"./configure --prefix=/usr/apache2".
I start, restart and stop Apache with the command:
apachectl start
apachectl restart
apachectl stop
and I see the result in the access_log and error_log, that are in the folder
/var/log/httpd.
I modify and add other files for the configuration of mod_jk in the folder
/usr/apache2.
I try to find if I have other configuration files in this computer...

Well then, it looks like none of these instructions are being read by
Apache when it starts. If only part of them were being read, then Apache
would write error messages to its error log, and probably refuse to start.
Are you sure that the files that you *think* are the configuration files
for Apache, really are ?
I am asking that because if I understand correctly, you used an Apache
"packaged" for Fedora, but the mod_jk part was done "by hand" following
separate instructions, so maybe the files you are modifying are not the
ones your Apache is really using.
How do you start/restart Apache ?

Hello André
I think that mod_jk is not loaded in Apache!
I have no message in the log referred to the module.
Following the guide of JBoss about the configuration of mod_jk, at the end
of httpd.conf I added this line:
Include conf/mod-jk.conf
and then I created in the same folder the file "mod-jk.conf" where I loaded
the module with the line:
LoadModule jk_module modules/mod_jk.so
where "modules" is the folder in Apache (/usr/apache2/modules) and then, in
the file, there are the other options about mod_jk.log and something else.

First, make sure that the mod_jk module is really being loaded in
Apache. When it is, you should normally see it in the first message
that Apache write to its "error" log when it starts, as follows :
[Wed Sep 17 03:58:10 2008] [notice] Apache/2.2.3 (Debian) DAV/2
SVN/1.4.2 mod_jk/1.2.18 PHP/4.4.4-8+etch4 mod_ssl/2.2.3 OpenSSL/0.9.8c
mod_perl/2.0.2 Perl/v5.8.8 configured -- resuming normal operations
see the "mod_jk" part ?
Now, I don't know Fedora and where it puts things, but in order to load
a module in Apache, some Apache configuration file must have a line like
LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so
do you see that anywhere ?

Did you "mounted" your application? What does apachectl configtest
returns? Any info in the error_log file?

I already do it in my "mod-jk.conf" file.
I have a line like this:
JkMount /application/* loadbalancer
But it doesn't work!

RE: [users@httpd] Apache, Jboss and mod_jk
Posted by Deepak Gupta <d....@mpstechnologies.com>.
Hi,
You need to JkMount your URLs from Apache to Jboss add this in your
mod-jk.conf or httpd.conf
JkMount /__application__/* loadbalancer

Subject: [users@httpd] Apache, Jboss and mod_jk
Hello!
I'm trying to find the solution of my problems in Nabble, but my search
isn't good.
I'm working with Jboss 4.2.3.GA, Apache 2.2.9 and mod_jk, everything working
on Fedora 8.
I would like to create a cluster of two computers and a loadbalancer based
on Apache.
I had no problems creating the cluster: my computers communicate and share
applications.
I installed Apache and it works, showing the Test Page.
Then I tried to configure the web server with mod_jk. I downloaded the
binary version of mod_jk and I followed the guide that I found on
http://www.jboss.org/file-access/default/members/jbossas/freezone/docs/Clust
ering_Guide/beta500/html_single/index.html#clustering-http-modjk
The only thing that I modified on configuration was the names of nodes in
workers.properties (I wrote the ip address of each node).
Therefore, after the configuration, I started Jboss on both machines, then
Apache (which is on one of two computers), then I tried to access to my
application, deployed on both Jboss instances, following the link
http://<ip-address>/application/<name-of-application>
What I see on my browser is a "404 not found" error, because Apache looks
for the application in /var/www/html/<name-of-application>
The same thing happens if I try to access to jmx-console of JBoss.
What I think is that the module mod_jk is not loaded and not working
correctly (in the log folder, mod-jk.log does not appear!)
I even tried to compile the sources of mod_jk and use this version of
module, but it doesn't work and it gives me the same error!
Any comments to help me?
Thanks guys!
