Pre-requisite:
|
||
|
|
--------------
|
||
|
|
1. jedis-2.8.0.jar (Available in - http://central.maven.org/maven2/redis/clients/jedis/2.8.0/jedis-2.8.0.jar)
|
||
|
|
2. commons-pool2-2.2.jar (Available in - http://central.maven.org/maven2/org/apache/commons/commons-pool2/2.2/commons-pool2-2.2.jar)
|
||
|
|
3. commons-logging-1.1.jar (Available in - http://central.maven.org/maven2/commons-logging/commons-logging/1.1.1/commons-logging-1.1.1.jar)
|
||
|
|
Note: Download all the above three jars and move it into tomcat/lib directory
|
||
|
|
|
||
|
|
|
||
|
|
Steps to be done,
|
||
|
|
-----------------
|
||
|
|
1. Add Tomcat system property "catalina.home"
|
||
|
|
catalina.home="TOMCAT_ROOT_LOCATION"
|
||
|
|
example: c:/ranjith/apache-tomcat-8.0.32
|
||
|
|
|
||
|
|
2. Download the TomcatRedisSessionManager-1.1.jar
|
||
|
|
Available in -
|
||
|
|
|
||
|
|
3. Move the downloaded jar (TomcatRedisSessionManager-1.1.jar) to tomcat/lib directory
|
||
|
|
$catalina.home/lib/TomcatRedisSessionManager-1.1.jar
|
||
|
|
example: c:/ranjith/apache-tomcat-8.0.32/lib/TomcatRedisSessionManager-1.1.jar
|
||
|
|
|
||
|
|
4. Extract downloaded jar (TomcatRedisSessionManager-1.1.jar) to configure redis data cache credentials in "RedisDataCache.properties" file and move the file to $catalina.home/conf directory
|
||
|
|
$catalina.home/conf/RedisDataCache.properties
|
||
|
|
example: c:/ranjith/apache-tomcat-8.0.32/conf/RedisDataCache.properties
|
||
|
|
|
||
|
|
5. Add the below two lines in $catalina.home/conf/context.xml
|
||
|
|
<Valve className="com.r.tomcat.session.management.RequestSessionHandlerValve" />
|
||
|
|
<Manager className="com.r.tomcat.session.management.RequestSessionManager" />
|
||
|
|
|
||
|
|
6. Verify the session expiration time in $catalina.home/conf/web.xml
|
||
|
|
<session-config>
|
||
|
|
<session-timeout>EXPIRATION TIME IN MINUTES</session-timeout>
|
||
|
|
</session-config>
|
||
|
|
|
||
|
|
Note:
|
||
|
|
-----
|
||
|
|
* This clustering implementation supports, both redis single node and cluster environment based on the RedisDataCache.properties configuration.
