所需組件包
jdk-1_5_0-linux-i586-rpm.bin ----Jkd
apache-tomcat-5.5.27.tar.gz ---Tomcat
httpd-2.0.63.tar.gz ---Apache
jakarta-tomcat-connectors-jk-1.2.1-src.tar.gz ---Apache和Tomcat連接器
安裝
1、 安裝Tomcat，Apache , mod_jk 上一篇文章已經講解
文件配置
配置
1、 修改Apache2/conf/httpd.conf文件
在最後加入
LoadModule jk_module modules/mod_jk.so
JkWorkersFile "conf/workers.properties"
JkLogFile "logs/mod_jk.log"
JkLogLevel Info
JkMount /*. workers
2、在apache2/conf/目錄下新建workers.properties文件內容如下
worker.list=workers,tomcat1,tomcat2
#========tomcat1========
worker.tomcat1.type=ajp13
worker.tomcat1.port=8009 #ajp13 端口號，在tomcat下server.xml配置,默認8009
worker.tomcat1.host=localhost #tomcat的主機地址，如不為本機，請填寫ip地址
worker.tomcat1.lbfactor=1
worker.tomcat1.fail_on_status=-500,-503,404
#========tomcat2========
worker.tomcat2.type=ajp13
worker.tomcat2.port=8010
worker.tomcat2.host=localhost
worker.tomcat2.lbfactor=1
worker.tomcat2.fail_on_status=500,503,-404
#========controller,負載均衡控制器========
worker.workers.type=lb
worker.retries=5
worker.workers.balance_workers=tomcat1,tomcat2
worker.workers.sticky_session=true
worker.workers.sticky_session_force=false
3、解決沖突，如果在同一台電腦上部署多個Tomcat 就要修改Tomcat端口, < xmlnamespace prefix ="o" ns ="urn:schemas-microsoft-com:office:office" />
找到tomcat/conf/server.xml文件 中如下地方
<Server port="8005" shutdown="SHUTDOWN">
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
修改為
8005 -------> 8015
8080 ------> 8081
8009------.>8019
注：<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
中的端口要與workers.properties文件中的worker.tomcat2.port=8019 配置一致
4 配置Session復制
1》分別找到每個Tomcat/conf/server.xl中
<Engine name="Catalina" defaultHost="localhost">
修改為
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">
2》分別在每個Tomcat/conf/server.xml的
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">
標簽中加入
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="6">
<!--
<Manager className="org.apache.catalina.ha.session.BackupManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"
mapSendOptions="6"/>
-->
<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"
