Apache+tomcat集群的整合配置

tar zxvf tomcat-connectors-1.2.28-src.tar.gz

cd tomcat-connectors-1.2.28-src/native

./configure --with-apxs=/usr/local/apache/bin/apxs --with-java-home=/usr/local/jdk

make ; make install

在/usr/local/apache/modules/ 下会产生mod_jk.so文件，然后修改apache配置文件:

vi /usr/local/apache/conf/httpd.conf

------------------------------------------------------------------------------------------------

LoadModule jk_module modules/mod_jk.so

JkWorkersFile conf/workers.properties

JkShmFile logs/mod_jk.shm

JkLogFile logs/mod_jk.log

JkLogLevel info

JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories

JkMount /* controller

JkUnMount /*.htm controller

jkUnMount /*.html controller

------------------------------------------------------------------------------------------------

更改DocumentRoot 为tomcat的部署目录

建立JK配置文件：

vi /usr/local/apache/conf/workers.properties

------------------------------------------------------------------------------------------------

workers.java_home=/usr/local/jdk

ps=/

worker.list=controller

worker.tomcat1.port=端口号

worker.tomcat1.host=IP地址

worker.tomcat1.type=ajp13

worker.tomcat1.lbfactor=1

worker.tomcat2.port=端口号

worker.tomcat2.host=IP地址

worker.tomcat2.type=ajp13

worker.tomcat2.lbfactor=1

worker.controller.type=lb

worker.controller.balance_workers=tomcat1,tomcat2

worker.controller.sticky_session=1

------------------------------------------------------------------------------------------------

修改web应用里面WEB-INF目录下的web.xml文件，加入标签

<distributable/>

直接加在</web-app>之前就可以了

做tomcat集群必须需要这一步，否则用户的session就无法正常使用。
