Hello friends, I am working on a server-configuration in which I would like to setup load-balancing with fail-over. Unfortunately, I am not having much luck with the process. I will be posting my updated config, so it is easier to understand. Kindly have a look.
First Tomcat's server.xml : <Connector port="443" enableLookups="false" protocol="HTTP/1.1" >> SSLEnabled="true" maxThreads="200" compression="force" >> compressionMinSize="1024" scheme="https" secure="true" clientAuth="false" >> sslProtocol="TLS" >> keystoreFile="keystore.jks" keystorePass="PASSWORD" URIEncoding="utf-8" >> compressableMimeType="text/html,text/xml,text/plain,text/css,text/ >> javascript,application/x-javascript,application/javascript" >> /> >> // I didn't remove the above connector, as I didn't knew how to use SSL >> with load-balancing and fail-over. >> > >> <Connector port="8010" protocol="AJP/1.3" redirectPort="443" >> URIEncoding="utf-8" >> compressableMimeType="text/html,text/xml,text/plain,text/css,text/ >> javascript,application/x-javascript,application/javascript" >> /> >> > <Engine name="Catalina" defaultHost="localhost" jvmRoute="server1"> > > <Host name="localhost" appBase="webapps" > unpackWARs="true" autoDeploy="true"> > <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" > channelSendOptions="8"> > > <Manager className="org.apache.catalina.ha.session.DeltaManager" > expireSessionsOnShutdown="false" > notifyListenersOnReplication="true"/> > > <Channel > className="org.apache.catalina.tribes.group.GroupChannel"> > <Membership > className="org.apache.catalina.tribes.membership.McastService" > address="228.0.0.4" // What kind of address is > this? > port="45564" > frequency="500" > dropTime="3000"/> > <Receiver > className="org.apache.catalina.tribes.transport.nio.NioReceiver" > address="148.251.151.18" > port="4000" > autoBind="100" > selectorTimeout="5000" > maxThreads="6"/> > > <Sender > className="org.apache.catalina.tribes.transport.ReplicationTransmitter"> > <Transport > className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/> > </Sender> > <Interceptor > className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/> > <Interceptor > className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/> > </Channel> > </Cluster> </Host> > Second tomcat config : > > <Connector port="443" enableLookups="false" protocol="HTTP/1.1" > SSLEnabled="true" maxThreads="200" compression="force" > compressionMinSize="1024" scheme="https" secure="true" > clientAuth="false" sslProtocol="TLS" > keystoreFile="keystore.jks" keystorePass="PAssword" > URIEncoding="utf-8" > compressableMimeType="text/html,text/xml,text/plain,text/css,text/ > javascript,application/x-javascript,application/javascript" > /> > <Connector port="8011" protocol="AJP/1.3" redirectPort="443" > URIEncoding="utf-8" > compressableMimeType="text/html,text/xml,text/plain,text/css,text/ > javascript,application/x-javascript,application/javascript" > /> <Engine name="Catalina" defaultHost="localhost" jvmRoute="server2"> > // The cluster config same as above, only the above stuff has changed. > workers.properties : worker.list=loadbalancer > worker.server1.port=8010 > worker.server1.host=localhost > worker.server1.type=ajp13 > > worker.server2.port=8011 > worker.server2.host=localhost > worker.server2.type=ajp13 > > worker.server1.lbfactor=1 > worker.server2.lbfactor=1 > > worker.loadbalancer.type=lb > worker.loadbalancer.balance_workers=server1,server2 > worker.loadbalancer.method=B > worker.balancer.sticky_session=true > 000-defaults in sites-enabled JkMountCopy On > <Proxy balancer://mycluster> > BalancerMember ajp://localhost:8010 route=server1 connectiontimeout=10 > BalancerMember ajp://localhost:8011 route=server2 connectiontimeout=10 > > ProxySet stickysession=JSESSIONID|jsessionid > Order Deny,Allow > Deny from none > Allow from all > > </Proxy> > > <VirtualHost *:80> > ProxyRequests off > > ProxyPass /balancer-manager ! > ProxyPass / balancer://mycluster/ > ProxyPassReverse / balancer://mycluster/ > </VirtualHost> > > <Location /balancer-manager> > SetHandler balancer-manager > > Order Deny,Allow > Deny from none > Allow from all > </Location> > This added in apache2.conf : JkWorkersFile /etc/apache2/workers.properties > > JkMount /* loadbalancer > Now, when both the tomcat versions are online, then I have no issues, but as soon as one tomcat goes down, then the whole setup dies. What am I doing wrong. Also, if I remove connector for 443, should I also remove the redirectPort in AJP connector. Kindly let me know. Thank you.
