Tomcat負載均衡及session共享
阿新 • • 發佈：2020-10-09
使用mod_proxy負載均衡：
[[email protected]conf]#vimhttpd.conf //引入配置檔案 include/usr/local/apache/conf/http-proxy.conf [[email protected]conf]#vimhttp-proxy.conf //新增以下內容 ProxyRequestsOff <proxybalancer://lbcluster1> BalancerMemberajp://192.168.1.115:8009loadfactor=10route=TomcatA BalancerMemberajp://192.168.1.116:8009loadfactor=10route=TomcatB ProxySetlbmethod=bytraffic </proxy> <VirtualHost*:80> ServerAdmin[email protected] ServerNamewww.w4ya.com ProxyViaOn ProxyPass/balancer://lbcluster1/stickysession=jsessionid ProxyPa***everse/balancer://lbcluster1/ </VirtualHost> <proxy*> Requireallgranted <proxy> <Location/> Requireallgranted </Location> <VirtualHost*:80> ServerNamewww.w4ya.com <Location/manager> SetHandlerbalancer-manager Requireallgranted </Location> </VirtualHost>
使用mod_jk實現負載均衡：
//引入配置檔案 [[email protected]conf]#vimhttpd.conf include/usr/local/apache/conf/jk.conf //新建並編輯vimjk.conf為如下內容： [[email protected]conf]#vimjk.conf LoadModulejk_modulemodules/mod_jk.so JkWorkersFile/usr/local/apache/conf/workers.properties JkLogFilelogs/mod_jk.log JkLogLeveldebug JkShmFilelogs/jk.shm JkMount/*dragon JkMount/status/stat 新建並編輯workers.properties，新增如下內容： [[email protected]conf]#vimworkers.properties worker.list=dragon,stat1 worker.TomcatA.type=ajp13 worker.TomcatA.host=192.168.1.115 worker.TomcatA.port=8009 worker.TomcatA.lbfactor=5 worker.TomcatB.type=ajp13 worker.TomcatB.host=192.168.1.116 worker.TomcatB.port=8009 worker.TomcatB.lbfactor=5 worker.dragon.type=lb worker.dragon.sticky_session=1 worker.dragon.balance_workers=TomcatA,TomcatB worker.stat1.type=status [[email protected]conf]#/usr/local/apache/bin/apachectl-t SyntaxOK [[email protected]conf]#/usr/local/apache/bin/apachectlstart
修改tomcat的server.xml，新增叢集配置:
<ClusterclassName="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="8"> <ManagerclassName="org.apache.catalina.ha.session.DeltaManager" expireSessionsOnShutdown="false" notifyListenersOnReplication="true"/> <ChannelclassName="org.apache.catalina.tribes.group.GroupChannel"> <MembershipclassName="org.apache.catalina.tribes.membership.McastService" address="222.222.0.1"//公共iP port="45564" frequency="500" dropTime="3000"/> <ReceiverclassName="org.apache.catalina.tribes.transport.nio.NioReceiver" address="192.168.1.1115"//tomcat本地主機，單網絡卡時也可以auto port="4000" autoBind="100" selectorTimeout="5000" maxThreads="6"/> <SenderclassName="org.apache.catalina.tribes.transport.ReplicationTransmitter"> <TransportclassName="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/> </Sender> <InterceptorclassName="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/> <InterceptorclassName="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/> </Channel> <ValveclassName="org.apache.catalina.ha.tcp.ReplicationValve" filter=""/> <ValveclassName="org.apache.catalina.ha.session.JvmRouteBinderValve"/> <DeployerclassName="org.apache.catalina.ha.deploy.FarmWarDeployer" tempDir="/tmp/war-temp/" deployDir="/tmp/war-deploy/" watchDir="/tmp/war-listen/" watchEnabled="false"/> <ClusterListenerclassName="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/> <ClusterListenerclassName="org.apache.catalina.ha.session.ClusterSessionListener"/> </Cluster>
在tomcat的網站目錄新建目錄WEB-INFO，並且編輯web.xml,在複製進去。
[[email protected]conf]#mkdir/var/www/html/WEB-INFO [[email protected]conf]#cp/usr/local/tomcat/conf/web.xml/var/www/html/WEB-INF/ [[email protected]conf]#vim/var/www/html/WEB-INF/web.xml //在<web-app>之間新增 <distributable/>
