Tomcat 5 + Apache 2 + mod_jk 2 实现虚拟主机

把这段代码保存为 /etc/rc.d/init.d/tomcat ，然后运行 [code:1:141851c2a4]chkconfig --add tomcat[/code:1:141851c2a4]即可把tomcat 添加为系统服务自动随系统启动了。这个脚本会在runlevel 3/4/5三种模式自动启动。注意这段脚本是为tomcat5创建的，如果你用tomcat4，则需要在另一个tomcat.sh的基础上修改。

5.编译和设置mod_jk
windows版本的mod_jk可以直接从 jakarta.apache.org 下载binary版本，linux下只好下载源代码编译了。从 http://jakarta.apache.org 下载 jakarta-tomcat-connectors-jk2-src-current.tar.gz 解压，然后 [code:1:141851c2a4]cd /jakarta-tomcat-connectors-jk2-2.0.2-src/jk/native2
./buildconf.sh[/code:1:141851c2a4]然后运行
[code:1:141851c2a4]./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-Java-home=/usr/local/j2sdk1.4.2-04[/code:1:141851c2a4]
(具体路径按照你实际的调整)
运行
[code:1:141851c2a4]make jk2-build-apxs
cd server/apache2
make -f Makefile.apxs install[/code:1:141851c2a4]
其实这个软件包本来有ant的配置文件，用ant编译可能会简单一些，但是要另外装ant，而且里面有些模块不是ant本身native的功能，还要为ant加装相应的功能模块，所以这里就略过，下次有时间再发一个ant的应用。

这样，你的mod_jk总算是装好了，现在开始进入配置阶段，其实，配置很简单了

6.设置虚拟主机
比如，我现在有虚拟主机 vhosts.vicp.net 希望把jsp和servlet都转到tomcat去，而其他的文件比如html页面，图片等等仍然用apache解析。
Tomcat设置：
修改 tomcat/conf/server.xml，在 <Engine></Engine>里面再增加一个<host/>，
[code:1:141851c2a4]<Host name="vhosts.vicp.net" debug="0"
appBase="/opt/jakarta-tomcat-4.1.12-LE-jdk14/webapps/struts-example"
