Solaris下安装配置httpd server与tomcat负载均衡

一。下载所需软件

         apache-tomcat-6.0.18.tar.gz

         mod_jk-1.2.27-httpd-2.2.6.so

         httpd-2.2.6.tar.gz

         jdk-1_5_0_16-solaris-sparc.sh

         jdk-1_5_0_16-solaris-sparcv9.sh

 

二。自解压安装java环境

        运行jdk-1_5_0_16-solaris-sparc.sh和jdk-1_5_0_16-solaris-sparcv9.sh

 

三。解压apache-tomcat-6.0.18.tar.gz，复制两个tomcat实例（同一台主机），比如apache-tomcat-6.0.18-1和apache-tomcat-6.0.18-2，把tomcat实例2的服务端口修改成与tomcat实例1不冲突的端口值

        <Server port="8006" shutdown="SHUTDOWN">

        <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8444" />

        <Connector port="8010" protocol="AJP/1.3" redirectPort="8444" />

 

四。安装配置httpd

        解压httpd-2.2.6.tar.gz，然后配置编译安装

        ./configure --prefix=/usr/local/httpd2.2.6 --enable-so --enable-mods-shared=most

        make

        make install

        把mod_jk-1.2.27-httpd-2.2.6.so复制到modules目录下，修改conf/httpd.conf文件

        LoadModule    jk_module  modules/mod_jk-1.2.27-httpd-2.2.6.so
        JkWorkersFile /usr/local/httpd2.2.6/conf/workers.properties

        JkShmFile        /usr/local/httpd2.2.6/conf/mod_jk.shm

        JkLogFile        /usr/local/httpd2.2.6/conf/mod_jk.log

        JkLogLevel    info

        JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

        JkMount  /*.jsp router
        JkMount  /*/servlet/* router

 

        workers.properties内容如下

        worker.list=router
        worker.router.type=lb
        worker.router.balance_workers=worker1,worker2
        worker.router.sticky_session=true

 

        worker.worker1.type=ajp13
        worker.worker1.host=localhost
        worker.worker1.port=8009
        worker.worker1.lbfactor=1
        

        worker.worker2.port=8010
        worker.worker2.host=localhost
        worker.worker2.type=ajp13
        worker.worker2.lbfactor=1

五。另外可以把两个tomcat组成一个cluster，实现会话复制共享

        tomcat实例1

            <Engine name="Catalina" defaultHost="localhost" jvmRoute="work1">

 

                Cluster节点内容

                  <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"
                        port="45564"
                        frequency="500"
                        dropTime="3000"/>
            <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                      address="auto"
                      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>

          <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
                 filter=""/>
          <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

          <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
                    tempDir="/tmp/war-temp/"
                    deployDir="/tmp/war-deploy/"
                    watchDir="/tmp/war-listen/"
                    watchEnabled="false"/>

          <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
          <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
     </Cluster> 

        tomcat实例2

        <Engine name="Catalina" defaultHost="localhost" jvmRoute="work2">

 

                Cluster节点内容

                  <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"
                        port="45564"
                        frequency="500"
                        dropTime="3000"/>
            <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                      address="auto"
                      port="4001"
                      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>

          <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
                 filter=""/>
          <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

          <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
                    tempDir="/tmp/war-temp/"
                    deployDir="/tmp/war-deploy/"
                    watchDir="/tmp/war-listen/"
                    watchEnabled="false"/>

          <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
          <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
     </Cluster>  
        

        然后在需要会话复制共享的应用的web.xml里加入<distributable/>，表示 Tomcat 要为此 Web 应用复制 Session
