多个tomcat同一个apache,使用jk建立关系时常出错！

多个项目，放在独立的tomcat上，并没有实现负载，要求实现静态化交给apache处理。

配置了3个tomcat通过jk和apache建立关系：

1. tom1存放项目名：d1
2. tom2存放项目名：news
3. tom3存放项目名：root

环境：（一台win2003服务器，，zip版本5.5.26的tomcat装了3个，，jk是1.2.26的，apache2.2.×）

我的实现方式：

每个tomcat根目录下写个bat脚本，用于同一个机器上启动多个tomcat

D:\Program\Tomcat5.5.26\startup_proname.bat

set CATALINA_HOME=D:\Program\Tomcat5.5.26
bin/startup.bat
（此处只写一个tomcat的配置server.xml就不多说了，其他的也如此）

贴出我的配置文件，一共5个：

• mod_jk.conf
• workers2.properties
• uriworkermap-d1.properties
• uriworkermap-news.properties
• uriworkermap-root.properties 
• httpd-vhosts.conf

#
# Virtual Hosts
#
# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at 
# <URL:http://httpd.apache.org/docs/2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# Use name-based virtual hosting.
#
NameVirtualHost *:80

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.

最后一个配置了，强调：我这里是3个项目分别用了3个tomcat，主要工程root实现了二级域名，其他两个功能有相应的域名

现在运行了2，3天时间发现偶尔会有异常，打不开现象，重启下影响不大，不过不知道原因很痛苦！

好久没处理这两篇问题文章了，今天一并解决下，作个结尾：

几位提示得都很对，
1.使用mod_proxy简单方便，期间观察很不错，比jk好多了（现在想知道谁把那东西搞得那么烦）！
2.ServerName demo.com  到http://www.demo.com就是把没有www开头得地址转换到站点地址www开头，这里面有个小小得问题，就是不能和泛域名放到一个 VirtualHost 里面，单独写个VirtualHost 放到配置文件最底下，原因是让所有满足*.demo.com先匹配，没有匹配到继续向下，是个线形顺序！

2 楼 robbin 2008-11-04  

apache的rewrite不用变，加两条mod_proxy的配置就行了。类似这样：

ProxyPass / ajp://localhost:8080/
ProxyPassReverse / ajp://localhost:8080/

1 楼 theone 2008-10-29  

废掉mod_jk，改用mod_proxy_ajp
