SSL support requires the following steps (see the SSL Config HOWTO in the Tomcat 5 documentation bundle for more detailed instructions): * If your JDK version 1.3 or prior, download and install JSSE 1.0.2 or later, and put the JAR files into "$JAVA_HOME/jre/lib/ext". * Execute: %JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA (Windows) $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA (Unix) with a password value of "changeit" for both the certificate and the keystore itself. By default, DNS lookups are enabled when a web application calls request.getRemoteHost(). This can have an adverse impact on performance, so you can disable it by setting the "enableLookups" attribute to "false".

So when running a cluster, only make sure that you have webapps in there that need to be clustered and remove the other ones. A cluster has the following parameters: className = the fully qualified name of the cluster class name = a descriptive name for your cluster, can be anything mcastAddr = the multicast address, has to be the same for all the nodes mcastPort = the multicast port, has to be the same for all the nodes mcastBindAddr = bind the multicast socket to a specific address mcastTTL = the multicast TTL if you want to limit your broadcast mcastSoTimeout = the multicast readtimeout mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes tcpListenAddress = the listen address (bind address) for TCP cluster request on this host, in case of multiple ethernet cards. auto means that address becomes InetAddress.getLocalHost().getHostAddress() tcpListenPort = the tcp listen port tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS has a wakup bug in java.nio. Set to 0 for no timeout printToScreen = true means that managers will also print to std.out expireSessionsOnShutdown = true means that useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called. false means to replicate the session after each request. false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager) <% HashMap map = (HashMap)session.getAttribute("map"); map.put("key","value"); %> replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'. * Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication. * Synchronous means that the thread that executes the request, is also the thread the replicates the data to the other nodes, and will not return until all nodes have received the information. * Asynchronous means that there is a specific 'sender' thread for each cluster node, so the request thread will queue the replication request into a "smart" queue, and then return to the client. The "smart" queue is a queue where when a session is added to the queue, and the same session already exists in the queue from a previous request, that session will be replaced in the queue instead of replicating two requests. This almost never happens, unless there is a large network delay. --> <!-- When configuring for clustering, you also add in a valve to catch all the requests coming in, at the end of the request, the session may or may not be replicated. A session is replicated if and only if all the conditions are met: 1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND 2. a session exists (has been created) 3. the request is not trapped by the "filter" attribute The filter attribute is to filter out requests that could not modify the session, hence we don't replicate the session after the end of this request. The filter is negative, ie, anything you put in the filter, you mean to filter out, ie, no replication will be done on requests that match one of the filters. The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to. filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI ending with .gif and .js are intercepted. The deployer element can be used to deploy apps cluster wide. Currently the deployment only deploys/undeploys to working members in the cluster so no WARs are copied upons startup of a broken node. The deployer watches a directory (watchDir) for WAR files when watchEnabled="true" When a new war file is added the war gets deployed to the local instance, and then deployed to the other instances in the cluster. When a war file is deleted from the watchDir the war is undeployed locally and cluster wide --> <!-- <Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" managerClassName="org.apache.catalina.cluster.session.DeltaManager" expireSessionsOnShutdown="false" useDirtyFlag="true" notifyListenersOnReplication="true"> <Membership className="org.apache.catalina.cluster.mcast.McastService" mcastAddr="228.0.0.4" mcastPort="45564" mcastFrequency="500" mcastDropTime="3000"/> <Receiver className="org.apache.catalina.cluster.tcp.ReplicationListener" tcpListenAddress="auto" tcpListenPort="4001" tcpSelectorTimeout="100" tcpThreadCount="6"/> <Sender className="org.apache.catalina.cluster.tcp.ReplicationTransmitter" replicationMode="pooled" ackTimeout="15000"/> <Valve className="org.apache.catalina.cluster.tcp.ReplicationValve" filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.*\.html;.*\.css;.*\.txt;"/> <Deployer className="org.apache.catalina.cluster.deploy.FarmWarDeployer" tempDir="/tmp/war-temp/" deployDir="/tmp/war-deploy/" watchDir="/tmp/war-listen/" watchEnabled="false"/> </Cluster> --> <!-- Normally, users must authenticate themselves to each web app individually.
