Request not redirecting to the server in the cluster.. Help
I have configured loadbalancer as belows and I the request are not redirecting to the correct servers. Please help me on this.
We have 2 jboss machines running on
1) 10.239.20.193 Port 8080
2) 10.239.96.181 Port 8080
We have installed Apache with mod_jk in another machine (10.239.19.149)
and have done the following configurations:
Configuration changes in JBoss Node 1 (10.239.20.193 Port 8080)
a) In server/all/deploy/jbossweb-tomcat55.sar/server.xml
we have modified the jvmRoute tag in <Engine tag to "node1"
b) Modified the useJK in the /server/all/deploy/jbossweb-tomcat55.sar/META-INF/jboss-service.xml to true
true
Configuration changes in JBoss Node 2 (10.239.96.181 Port 8080)
a) In server/all/deploy/jbossweb-tomcat55.sar/server.xml
we have modified the jvmRoute tag in <Engine tag to "node2"
b) Modified the useJK in the /server/all/deploy/jbossweb-tomcat55.sar/META-INF/jboss-service.xml to true
true
Configuration changes in Load balancer machine:
a) Modified httpd.conf
Included the following block at the end:
# Include mod_jk's specific configuration file
Include conf/mod-jk.conf
b) Create mod-jk.conf with the following contents:
# 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 /ppm/* 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
c) Created uriworker.properties with the following contents:
# Simple worker configuration file
# Mount the Servlet context to the ajp13 worker
/jmx-console=loadbalancer
/jmx-console/*=loadbalancer
/web-console=loadbalancer
/web-console/*=loadbalancer
d) Created worker.properties with the following contents:
# Define list of workers that will be used
# for mapping requests
worker.list=loadbalancer,status
# Define Node1
# modify the host as your host IP or DNS name.
worker.node1.port=8080
worker.node1.host=10.239.20.193
worker.node1.type=ajp13
worker.node1.lbfactor=1
worker.node1.cachesize=10
# Define Node2
# modify the host as your host IP or DNS name.
worker.node2.port=8080
worker.node2.host=10.239.96.181
worker.node2.type=ajp13
worker.node2.lbfactor=1
worker.node2.cachesize=10
# Load-balancing behaviour
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=node1,node2
worker.loadbalancer.sticky_session=1
#worker.list=loadbalancer
# Status worker for managing load balancer
worker.status.type=status
When we try to hit the apache mod-jd with the following url we get the output in the log file as
