 Liferay JBoss Master/Slave Failover Mode Configuration

 

 

1Prepare software

1.1Apache 2.2 httpd-2.2.22-win32-x86-openssl-0.9.8t.msi

1.2LF JBoss(2 instances) 

1.3mod_jk.so tomcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zip

 

 

2mod_jk.so

2.1Rename to mod_jk.so and copy to %APACHE_HOME%/modules directory

 

2.2Load the mod_jk.so connector

Modify %APACHE_HOME%/conf/httpd.conf file, add below line to bottom line.

LoadModule jk_module modules/mod_jk.so

 

2.3Configure mod_jk for cluster nodes.

Modify “httpd.conf” file, add below lines to bottom line. 

JkWorkersFile conf/workers.properties

JkLogFile logs/mod_jk.log

JkMount /* loadbalancer

 

2.4Need to create a file named workers.properties in conf directory. And add below lines in it.

# Define list of workers that will be used

# for mapping requests

worker.list=loadbalancer,status

 

# Define Master

worker.master.host=10.25.153.107

worker.master.port=8009

worker.master.type=ajp13

worker.master.lbfactor=1

worker.master.cachesize=10

worker.master.cache_timeout=600

worker.master.socket_timeout=5

worker.master.recycle_timeout=20

worker.slave.prepost_timeout=1

worker.master.recovery_options=0

worker.master.connection_pool_timeout=5

worker.master.ping_mode=A

worker.master.ping_timeout=500

worker.master.connect_timeout=500

 

# Define prefered failover node for master

worker.master.redirect=slave

 

# Define Slave

worker.slave.host=127.0.0.1

worker.slave.port=8009

worker.slave.type=ajp13

worker.slave.lbfactor=1

worker.slave.cachesize=10

worker.slave.cache_timeout=600

worker.slave.socket_timeout=60

worker.slave.recycle_timeout=100

worker.slave.prepost_timeout=50

worker.slave.recovery_options=0

worker.slave.connection_pool_timeout=60

worker.slave.ping_mode=A

worker.slave.ping_timeout=20000

worker.slave.connect_timeout=20000

 

#Disable slave for all requests except failover

worker.slave.activation=disabled

 

# Load-balancing behaviour

worker.loadbalancer.type=lb

worker.loadbalancer.balance_workers=master,slave

worker.loadbalancer.sticky_session=1

 

# Status worker for managing load balancer

worker.status.type=status

 

 

3Configure JBoss to Cluster node.

3.1In file standalone/configuration/standalone.xml, add content as grew part below

<subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" instance-id="master" native="false">

            <configuration>

                <jsp-configuration development="true"/>

            </configuration>

            <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>

            <connector name="ajp" protocol="AJP/1.3" scheme="http" socket-binding="ajp"/>

            <virtual-server name="default-host" enable-welcome-root="false">

                <alias name="localhost"/>

                <alias name="example.com"/>

            </virtual-server>

        </subsystem>

 

3.2Add interface for specific ip

Add gray part as below, and change xxx.yyy.aaa.bbb to your jboss server ip.

<interfaces>

        <interface name="management">

            <inet-address value="${jboss.bind.address.management:127.0.0.1}"/>

        </interface>

        <interface name="public">

            <inet-address value="${jboss.bind.address:127.0.0.1}"/>

        </interface>

        <interface name="unsecure">

            <inet-address value="${jboss.bind.address.unsecure:127.0.0.1}"/>

        </interface>

        <interface name="specific-ip-interface">

            <inet-address value=" xxx.yyy.aaa.bbb "/>

        </interface>

</interfaces> 

 

3.3Change below gray part according to the interface added above.

 

<socket-binding-group name="standard-sockets" default-interface="specific-ip-interface" port-offset="${jboss.socket.binding.port-offset:0}">

<socket-binding name="management-native" interface="specific-ip-interface" port="${jboss.management.native.port:9999}"/>

<socket-binding name="management-http" interface="specific-ip-interface" port="${jboss.management.http.port:9990}"/>

<socket-binding name="management-https" interface="specific-ip-interface" port="${jboss.management.https.port:9443}"/>

<socket-binding name="ajp" port="8009"/>

 

 

4Configure Portal portal-ext.properties

cluster.link.enabled=true

lucene.replicate.write=true

 

5Test cluster server

5.1Visit URL http://localhost, you will see apache server default page.

5.2Visit URL http://localhost/c/portal/login twice with two browsers, you will see 

the same page which response by master node as below.

 

5.3Shut down master node, observe the page from salve node as below.
