Configuring Tomcat for memcached persisted sessions on Ubuntu

gistfile1.txt

1. Get the memcached session persistence JAR files.

wget http://repo1.maven.org/maven2/de/javakaffee/msm/memcached-session-manager/1.8.2/memcached-session-manager-1.8.2.jar
wget http://repo1.maven.org/maven2/de/javakaffee/msm/memcached-session-manager-tc7/1.8.2/memcached-session-manager-tc7-1.8.2.jar
wget http://repo1.maven.org/maven2/net/spy/spymemcached/2.11.1/spymemcached-2.11.1.jar

2. Copy those files into the Tomcat lib folder.

sudo cp memcached-session-manager-* /usr/share/tomcat7/lib
sudo cp spymemcached-* /usr/share/tomcat7/lib

3. Configure Tomcat's context.xml file.

/etc/tomcat7/context.xml:

<!-- The contents of this file will be loaded for each web application -->
<Context>

    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>

    <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
             memcachedNodes="tomcat-sessions.ark24w.cfg.euw1.cache.amazonaws.com:11211"
             requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" />

    <!-- Uncomment this to disable session persistence across Tomcat restarts -->
    <!--
    <Manager pathname="" />
    --> 

    <!-- Uncomment this to enable Comet connection tacking (provides events
         on session expiration as well as webapp lifecycle) -->
    <!--
    <Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />
    -->

</Context>

4. Restart Tomcat
