Apache HttpServer与Tomcat的整合见上篇：

http://blog.csdn.net/supercrsky/article/details/8295023

一.配置Tomcat

这里用两个tomcat，直接在已安装目录再复制一个，命名为tomcat2。

#cp -r /opt/tomcat/ tomcat2

进入tomcat2目录，编辑 conf/server.xml，修改默认端口。

#vi conf/server.xml

1.  将

<Server port="8005" shutdown="SHUTDOWN">

改成

<Server port="9005" shutdown="SHUTDOWN">

2.将

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" /> 

修改成：

<Connector port="9090" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="9443" /> 

3. 找到：

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

改成

<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">

同时把tomcat2中此处内容改成

<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">

4.找到

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

改成

<Connector port="9009" protocol="AJP/1.3" redirectPort="8443" />

5.找到

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" />

把注释取消掉。

二．配置HTTP Server

1.检查是否启动了https，确保下面这句已经被注释。

#Include conf/extra/httpd-ssl.conf

2.找到我们在最文件最下面添加的VirtualHost节点，将其更改为： 

<VirtualHost *>
DocumentRoot /usr/local/www/
<Directory "/usr/local/www/composite">
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>
<Directory "/usr/local/www/composite/WEB-INF">
         Order deny,allow
         Deny from all
</Directory>
ServerAdmin localhost
DocumentRoot /usr/local/www/
ServerName localhost
DirectoryIndex index.html index.htm index.jsp index.action
ErrorLog logs/shsc-error_log.txt
CustomLog logs/shsc-access_log.txt common

JkMount /*WEB-INF controller
JkMount /*j_spring_security_check controller
JkMount /*.action controller
JkMount /servlet/* controller
JkMount /*.jsp controller
JkMount /*.do controller
</VirtualHost>

4. 编辑conf/workers.properties将内容修改为：

worker.list = controller
#tomcat1
worker.tomcat1.port=8009       
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor=1
#tomcat2
worker.tomcat2.port=9009     
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor=1
#========controller========
worker.controller.type=lb
worker.controller.balance_workers=tomcat1,tomcat2
worker.lbcontroller.sticky_session=0
worker.controller.sticky_session_force=true
worker.connection_pool_size=3000
worker.connection_pool_minsize=50
worker.connection_pool_timeout=50000

这句非常重要worker.list = controller，如果不加httpd会无法启动，查看日志报错：

Could not find a worker for worker name=controller

如果是横向集群，将worker.tomcat1.host或worker.tomcat2.host更改为对应的机器IP即可。

三．部署并测试

 确保项目里的WEB-INF/web.xml文件，在</web-app>之前加入了

 <distributable/>

 将工程分别部署到/usr/local/www，/opt/tomcat/webapps，/opt/tomcat2/webapps

 分别启动tomcat1和tomcat2，顺序无所谓，最后启动HTTP Server

#/opt/tomcat/bin/startup.sh

#/opt/tomcat2/bin/startup.sh

#/usr/local/httpd2.2/bin/apachectl start

启两个Firefox，分别访问我们的工程，这里是:http://localhost/composite

观察/opt/tomcat/logs/与/opt/tomcat2/logs/下对应的日志，

我们发现tomcat1和tomcat2已经分别处理了一个客户端请求。
