JBoss 6 Cluster

Jboss6 Cluster

Download apache2.2 from the Apache website,

Download mod_jk.so and put it in the % apache_home % \ modules directory.

Add include CONF/mod-jk.conf to the end of httpd. conf file under % apache_home % \ conf

 

 

Create the workers. properties file in the % apache_home % \ conf directory.

The content is as follows:

# 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 = 8009
Worker. node1.host = 172.22.71.133
Worker. node1.type = ajp13
Worker. node1.lbfactor = 1

# Define node2
# Modify the host as your host IP or DNS name.

# The following port corresponds to the AJP port in the jobss6 % jboss_home % \ Server \ All \ deploy \ jbossweb. Sar server. xml file, not 8080
Worker. node2.port = 8009
Worker. node2.host = 172.22.71.119
Worker. node2.type = ajp13
Worker. node2.lbfactor = 1

# 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

 

Create the file uriworkermap. properties in the directory % APACHE_HOME % \ conf.

The content is as follows:

/Jmx-console = loadbalancer
/Jmx-console/* = loadbalancer
/Web-console = loadbalancer
/Web-console/* = loadbalancer

 

Create mod_jk.conf in the % APACHE_HOME % \ conf directory.

The content is as follows:

# 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/* 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 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>

 

Apache configuration is complete

 

 

Configure jboss6

In the server. xml file under the % JBOSS_HOME % \ server \ all \ deploy \ jbossweb. sar directory, modify the content:

Original content:

<! -- A http/1.1 Connector on port 8080 -->
<Connector protocol = "HTTP/1.1" port = "$ {jboss. web. http. port}" address = "$ {jboss. bind. address }"

RedirectPort = "$ {jboss. web. https. port}"/>

<! -- Add this option to the connector to avoid problems
. NET clients that don't implement HTTP/1.1 correctly
RestrictedUserAgents = "^. * MS Web Services Client Protocol 1.1.4322. * $"
-->

<! -- A ajp 1.3 Connector on port 8009 -->
<Connector protocol = "AJP/1.3" port = "$ {jboss. web. ajp. port}" address = "$ {jboss. bind. address }"
RedirectPort = "$ {jboss. web. https. port}"/>

 

Modify to: note that the following port 8009 is the port on the APACHE node above .. It took a long time to figure it out.

<! -- A http/1.1 Connector on port 8080 -->
<Connector protocol = "HTTP/1.1" port = "$ {jboss. web. http. port}" address = "$ {0.0.0.0 }"

RedirectPort = "$ {jboss. web. https. port}"/>

<! -- Add this option to the connector to avoid problems
. NET clients that don't implement HTTP/1.1 correctly
RestrictedUserAgents = "^. * MS Web Services Client Protocol 1.1.4322. * $"
-->

<! -- A ajp 1.3 Connector on port 8009 -->
<Connector protocol = "AJP/1.3" port = "$ {jboss. web. ajp. port}" address = "$ {0.0.0.0 }"
RedirectPort = "$ {jboss. web. https. port}"/>

 

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

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

JvmRoute = "node1" is the node name.

 

In the META-INF file under the % JBOSS_HOME % \ server \ all \ deployers \ jbossweb. deployer \ war-deployers-jboss-beans.xml directory, modify the content:

Original content:

<Property name = "useJK"> true </property>
<! --
<Property name = "useSessionPassivation"> false </property>
<Property name = "passivationMaxIdleTime">-1 </property>
<Property name = "passivationMinIdleTime">-1 </property>
-->

 

To:

<Property name = "useJK"> true </property>
<Property name = "useSessionPassivation"> true </property>
<Property name = "passivationMaxIdleTime">-1 </property>
<Property name = "passivationMinIdleTime">-1 </property>

 

That is, do not open comments to set false to true.

 

Configure several other jboss servers
