apche+tomcat集群配置方法

2013-12-24 08:37:01 来源:kejihao

操作系统:Debian6.0 (192.168.225.129 虚拟机1台)

软件版本:Apache-2.2.16, Tomcat-6.0.35

1.安装软件

>apt-get install update

*安装Apache

>apt-get install apache2

*安装Tomcat

>wget http://apache.etoak.com/tomcat/tomcat-6/v6.0.35/bin/apache-tomcat-6.0.35.tar.gz

>tar zxvf apache-tomcat-6.0.35.tar.gz

>mv apache-tomcat-6.0.35 /user/local/tomcat

>cp /usr/local/tomcat /usr/local/tomcat2

*安装mod_jk

>apt-get install libapache2-mod-jk

2.配置2个Tomcat

现在/usr/local目录中已经有2个tomcat目录了,需要更改tomcat2的端口,防止端口冲突。

>nano /usr/local/tomcat/conf/server.xml

有3处的默认端口需要更改:

1.<Server port="8004" shutdown="SHUTDOWN"> 我更改为8003

2.<Connector port="8080" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443" />

更改为7080

3.<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

更改为7009,其中redirectPort 8443不需要更改

o.另外还需要在<Engine>配置中加入<Cluster>配置

<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"

selectorTimeout="5000"

maxThreads="6"/>

<!-- timeout="60000"-->

<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"/>

<Interceptor className="org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor"/>

</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>

<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"      selectorTimeout="5000"      maxThreads="6"/>            <!-- timeout="60000"-->            <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"/>            <Interceptor className="org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor"/>        </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>

x.最后2个tomcat都需要改变<Engine的 jvmRoute属性分别为tomcat1和tomcat2,以对应之后worker.properties中的名字。

3.配置Apache以jk方式和tomcat集群

安装完成后apache的主目录为/etc/apache2,安装完mod-jk之后,mods-enabled里面会多一个jk.load

创建文件 /etc/apache2/mods-enabled/jk.conf

>nano /etc/apache2/mods-enabled/jk.conf

JkWorkersFile /etc/apache2/workers.properties

JkShmFile /var/log/apache2/mod_jk.shm

JkLogFile /var/log/apache2/mod_jk.log

JkLogLevel info

创建文件 /etc/apache2/workers.properties

>nano /etc/apache2/workers.properties

worker.list=controller1

worker.tomcat1.port=8009

worker.tomcat1.host=localhost

worker.tomcat1.type=ajp13

worker.tomcat1.lbfactor=1

worker.tomcat2.port=7009

worker.tomcat2.host=localhost

worker.tomcat2.type=ajp13

worker.tomcat2.lbfactor=1

worker.controller1.type=lb

worker.controller1.sticky_session=1 #可选项0,1

worker.controller1.balance_workers=tomcat1,tomcat2

更改/etc/apache2/sites-enabled/000-default文件

在</VirtualHost>之前添加

JkMount /* controller1

(controller1对应workers.properties中的名字)

配置完成之后先后启动tomcat和apache。

测试:

2个tomcat部署相同的应用:即首页index.jsp显示各自tomcat名称tomcat1和tomcat2

通过80端口访问应用,刷新几次,tomcat1和tomcat2轮流显示。
