Apache workers.properties help please.

[andrewboyd]

Hi All,
I'm using JBoss portal 2.4.0 final and Apache/2.0.52 (Red Hat) Server.

I followed the instructions found in the wiki http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingMod_jk1.2WithJBoss

as best as I could for my single server but I'm getting a 404 error when trying to access /web-console and /jmx-console. Here is my workers.properties:

# Define list of workers that will be used
# for mapping requests
# The configuration directives are valid
# for the mod_jk version 1.2.18
#
#worker.list=loadbalancer,status
# since myDomain only has one server at this time
worker.list=node1

# Define Node1
# modify the host as your host IP or DNS name.
worker.node1.port=8009
worker.node1.host=node1.myDomain.com
worker.node1.type=ajp13
worker.node1.lbfactor=1
# worker.node1.connection_pool_size=10 (1)

# since myDomain only has one server at this time comment out node2
# Define Node2
# modify the host as your host IP or DNS name.
#worker.node2.port=8009
#worker.node2.host= node2.myDomain.com
#worker.node2.type=ajp13
#worker.node2.lbfactor=1
# worker.node1.connection_pool_size=10 (1)

# Load-balancing behaviour
worker.loadbalancer.type=lb
#worker.loadbalancer.balance_workers=node1,node2
worker.loadbalancer.balance_workers=node1

# Status worker for managing load balancer
#worker.status.type=status

I replaced my real domain with myDomain just in this posting.

I also commented out node2 from the wiki example since I only have one server. I also commented out the worker.status.type=status.

I have installed mod_jk version 1.2.18

rpm -Uvh mod_jk-1.2.18-1.rhel4.bjd.i386.rpm

My uriworkermap.properties file is straight from the wiki:

# Simple worker configuration file
#

# Mount the Servlet context to the ajp13 worker
/jmx-console=loadbalancer
/jmx-console/*=loadbalancer
/web-console=loadbalancer
/web-console/*=loadbalancer

I added jvmRoute to my JBOSS_HOME/server/inetMillionaire/deploy/jbossweb-tomcat55.sar/server.xml

<Engine name="jboss.web" defaultHost="localhost" jvmRoute="node1">

and I made sure that the jbossweb-tomcat55.sar/META-INF/jboss-service.xml is set to use JK

<attribute name="UseJK">true</attribute>

Anyone see what I've done wrong?

Thanks in advance,

Andrew

Its still not working but a little bit of sleep has helped me see at least one mistake.

I did not have the loadbalancer in my worker.list but I referenced it in my uirworkermap.properties

so now my workers.properties looks like:

worker.list=loadbalancer,status


# Define Node1
# modify the host as your host IP or DNS name.
worker.node1.port=8009
worker.node1.host=node1.howibecameaninternetmillionaire.com
worker.node1.type=ajp13
worker.node1.lbfactor=1
# worker.node1.connection_pool_size=10 (1)

# since inetMillionaire only has one server at this time comment out node2
# Define Node2
# modify the host as your host IP or DNS name.
#worker.node2.port=8009
#worker.node2.host= node2.howibecameaninternetmillionaire.com
#worker.node2.type=ajp13
#worker.node2.lbfactor=1
# worker.node1.connection_pool_size=10 (1)

# Load-balancing behaviour
worker.loadbalancer.type=lb
#worker.loadbalancer.balance_workers=node1,node2
worker.loadbalancer.balance_workers=node1

# Status worker for managing load balancer
worker.status.type=status

Any ideas?

Thanks,

Andrew

I was looking at my mod-jk.conf:

# Load mod_jk module
# Specify the filename of the mod_jk lib
LoadModule jk_module modules/mod_jk.so

# Where to find workers.properties
JkWorkersFile conf/workers.properties

# Where to put jk logs
JkLogFile logs/mod_jk.log

# Set the jk log level [debug/error/info]
JkLogLevel info

# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

# JkOptions indicates to send SSK KEY SIZE
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories

# JkRequestLogFormat
JkRequestLogFormat "%w %V %T"

# Mount your applications
JkMount /application/* loadbalancer

# You can use external file for mount points.
# It will be checked for updates each 60 seconds.
# The format of the file is: /url=worker
# /examples/*=loadbalancer
JkMountFile conf/uriworkermap.properties

# Add shared memory.
# This directive is present with 1.2.10 and
# later versions of mod_jk, and is needed for
# for load balancing to work properly
JkShmFile logs/jk.shm

# Add jkstatus for managing runtime data
<Location /jkstatus/>
JkMount status
Order deny,allow
Deny from all
Allow from 127.0.0.1
</Location>

This line looks like it is not correct:

# Mount your applications
JkMount /application/* loadbalancer

I don't have a /application/ directory does anyone know if this is wrong or what I should have this set to?

Thanks,

Andrew

change this line

worker.node1.host=node1.howibecameaninternetmillionaire.com

to

worker.node1.host=howibecameaninternetmillionaire.com

i am not sure but before 2 weeks i make the same configuration and it works

[andrewboyd]

Thanks for the reply golanbln. I tried your suggestion but still no luck.

[andrewboyd]

Ok I checked out the Apache error.log and saw:

File does not exist: /var/www/html/web-console

The /var/www/html is set as my document root.

I just tried to set my JBOSS_HOME/server/myServer/deploy as DocumentRoot. It did not work. But I think we're getting closer.

The error log says:
File does not exist: /srv/website/mySite/app-server/jboss-portal/server/myServer/deploy/web-console

Do I need to set the document root to something or am I going down the wrong path?

Any suggestions?

Thanks,

Andrew

Did you do Step #3 from http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingMod_jk1.2WithJBoss ?

The "File does not exist" log sounds like it's not picking up that web-console is handled by mod_jk. Your uriworkersmap.properties looks OK, as does the mod-jk.conf, so I wonder if it's just Step #3 missing.

[andrewboyd]

Thanks Bstansberry!

Its not totaly working but missing Step #3 (the smallest step) seems to be what my road block was. Now I'm getting

"The server encountered an internal error or misconfiguration and was unable to complete your request."

thanks again,

Andrew

[andrewboyd]

Thanks to Bstansberry for pointing out I missed step #3.

I put the Document Root back to what it was and I followed the advice of golanbln and removed the node1 from worker.node1.host=node1....

And I can now get to the web-console.

Thanks everyone!

Andrew
