Jboss apache integration

Apache JBOSS integration

1) Download mod_jk module from

http://www.gtlib.gatech.edu/pub/apache/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.28/i586/

2) Copy mod_jk-1.2.28-httpd-2.2.X.so to /opt/apacheconf

3) Edit the httpd.conf and add the following line

Include /opt/apacheconf/mod-jk.conf

4) Create /opt/apacheconf/mod-jk.conf file with the following content

LoadModule jk_module /opt/apacheconf/mod_jk-1.2.28-httpd-2.2.X.so

JkWorkersFile /opt/apacheconf/workers.properties

JkLogFile /opt/apachelogs/mod_jk.log

JkLogLevel info

JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

JkOptions +ForwardKeySize +ForwardURICompatUnparsed -ForwardDirectories

JkRequestLogFormat "%w %V %T"

JkMountFile /opt/apacheconf/uriworkermap.properties

JkShmFile /opt/apachelogs/jk.shm

<Location /jkstatus>

JkMount status

#Order deny,allow

#Deny from all

#Allow from 127.0.0.1

</Location>

5) Create /opt/apacheconf/uriworkermap.properties file with the following content

# Simple worker configuration file

# Mount the Servlet context to the ajp13 worker

/jmx-console=loadbalancer

/jmx-console/*=loadbalancer

/web-console=loadbalancer

/web-console/*=loadbalancer

/testWeb/*=loadbalancer

!/testWeb/images/*=loadbalancer

6) Create /opt/apacheconf/workers.properties file with the following content

worker.list=loadbalancer,status

# Define Node1

# modify the host as your host IP or DNS name.

worker.node1.port=8009

worker.node1.host={jboss-server-ip-address goes here}

worker.node1.type=ajp13

worker.node1.lbfactor=1

worker.node1.prepost_timeout=10000 #Not required if using ping_mode=A

worker.node1.connect_timeout=10000 #Not required if using ping_mode=A

worker.node1.ping_mode=A #As of mod_jk 1.2.27

# worker.node1.connection_pool_size=10 (1)

# 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.node2.prepost_timeout=10000 #Not required if using ping_mode=A

#worker.node2.connect_timeout=10000 #Not required if using ping_mode=A

#worker.node2.ping_mode=A #As of mod_jk 1.2.27

# 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

The above configuration is to test with one app server functionally.

7) Update /opt/apacheconf/httpd-vhosts.conf with JkMount

Listen 9080

NameVirtualHost *

<VirtualHost *>

ServerName {server-name}

ServerAlias {alias}

JkMount /testWeb loadbalancer

JkMount /testWeb/* loadbalancer

</VirtualHost>

8) Update the following line to include jvmRoute in /opt/jboss-eap-5.0/jboss-as/server/default/deploy/jbossweb.sar/server.xml

<Engine name="jboss.web" defaultHost="localhost" jvmRoute="domain-name-goes-here">

9) Restart Apache and JBOSS server

10) Test the web server URL http://{domain-name}/testWeb/test.jsp
