软件版本
apache-tomcat-5.5.27.zip
httpd-2.0.63.tar.gz
mod_jk-1.2.28-httpd-2.0.X.so
涉及到的文件存放路径
apache home = /usr/local/apache
相关配置文件路径在/usr/local/apache/conf 目录下
httpd.conf、mod_jk.conf、vhost、workers.properties
ofbiz安装目录
swg_home = /usr/local/swg
zbb_home = /usr/local/zbb
原理：
apache侦听80端口；通过VirtuHost实现一个ip绑定多个域名；通过更改java端口来实现一台机器上启动多个ofbiz；通过ajp13模块与tomcat协议通信
apache配置
1,install apache
./configure --prefix=/usr/local/apache/ --enable-so
make
make install
2,install mod_jk
将mod_jk-1.2.28-httpd-2.0.X.so拷贝至 /usr/local/apache/modules/mod_jk.so
ofbiz配置
编辑 /usr/local/swg/startofbiz.sh 和 stopofbiz.sh 为其指定java路径
编辑 /usr/local/zbb/startofbiz.sh 和 stopofbiz.sh 为其指定java路径
export JAVA_HOME=/usr/local/swg/jdk1.5
export JAVA=$JAVA_HOME/bin/java
指定ajp13通信使用的端口
tomcat默认为8009，如果在一台机器上运行多个tomcat（ofbiz）那么就要更改相应的端口，我们只关心8009的更改情况，其他端口交给开发人员更改。
配置ajp13的文件是: /usr/local/swg/framework/base/config/ofbiz-containers.xml
测试
在自己电脑的hosts文件中添加
192.168.254.212 www.zbb1.com
192.168.254.212 www.swg1.com
在浏览器中分别输入 http://www.zbb1.com http://www.swg1.com 即可看到相应的内容。
