Apache load balancing using mod_jk

Considering you have two tomcat server's and both are configured and port 8009 is listened by ajp in tomcat.

Download the module from http://tomcat.apache.org/download-connectors.cgi

Sample Version http://apache.mirrors.hoobly.com/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.40-src.tar.gz

#tar -xvf tomcat-connectors-1.2.37-src.tar

# cd tomcat-connectors-1.2.32-src/native/

# which usr/sbin/apxs

# ./configure --with-apxs=/usr/sbin/apxs --enable-api-compatibility

# make

# make install

after completed this activity you will get mod_jk.so file in /usr/lib64/httpd/modules/mod_jk.so

or else copy the modules to apache's module directory.

 

if get it , going well

Installation part has been completed, let's start configuration part

4. Open httpd.conf file and add end of line.

# vi /etc/httpd/conf/httpd.conf

JkWorkersFile "/etc/httpd/conf/worker.properties"
JkLogFile "/var/log/httpd/mod_jk.log"
JkRequestLogFormat "%w %V %T"
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

The below two lines in the virtualhost.

JkMount / loadbalancer
JkMount /status status

Content of the worker.properties

cat /etc/httpd/conf/worker.properties
worker.list=loadbalancer,status

worker.template.type=ajp13
worker.template.connection_pool_size=50
worker.template.socket_timeout=1200

worker.node2.reference=worker.template
worker.node1.port=8009
worker.node1.host=54.86.231.61
worker.node1.type=ajp13
worker.node2.jvm_route=node1

worker.node2.port=8009
worker.node2.host=54.86.17.252
worker.node2.type=ajp13
worker.node2.jvm_route=node2

worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=node1,node2
#worker.loadbalancer.sticky_session=TRUE

to check the status

worker.status.type=status

 

 

 

Tomcat-Static-Unicast-Clustering

Tomcat needs to be configured to allow for setup of cluster of two nodes over unicast. Following is section of my ${LIFERAY_HOME}/tomcat-6.0.32/conf/server.xml on server1 (replace node1 with node2 and swap location of IP_ADDRESSES and change unique_id to anything 16 bit long other than{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,2}, on server.xml in server2) which allowed for this. IP_ADDRESSES here refer to private ip addresses of server1 and server2 respectively.
