对于java应用服务器，常用的一般为tomcat、jboss、resin。
一. 概述
经常会有这种情况：
1、一台服务器上，跑多个java应用
2、网站负载高，需要采用负载均衡（轮询）的方式来解决
一般用多个java应用服务器软件，或者用一个采用集群的方式；
二. 跑多个项目，或者做balance的方法
方法一：再安装一个resin，指向不同的项目目录
在安装完毕之后：
修改resin.conf里面的http port、cluster port和web-app目录；启动，就ok了。
方法二：只安装一个resin，使用不同的配置文件，指向不同的项目目录。方法二的配置相对复杂些。
1.安装好一个resin之后，cp resin.conf resin1.conf,分别修改另个resin，找到找到配置文件中的<!-- define the servers in the cluster -->,修改负载均衡配置,需要设置服务的ID、IP和port。 resin.conf修改为：
<server id="yk" address="127.0.0.1" port="6800"/>
resin1.conf 修改为：
<server id="yk1" address="127.0.0.1" port="6801"/>
resin2.con修改为：
<server id="yk2" address="127.0.0.1" port="6802"/> 注：其中修改http port,web-app 目录，jvm参数、最大线程数的修改，根据需要去调整。
2.拿部署的配置跟我的配置对比下：
[yangkai@mp2 conf]$ diff resin.conf webresin
84c84
< <cluster id="app-tier"> ---
> <cluster id="app-1">
107c107
< <jvm-arg>-Xmx256m</jvm-arg> ---
> <jvm-arg>-Xmx3096m</jvm-arg>
130c130
< <thread-max>256</thread-max> ---
> <thread-max>20480</thread-max>
149c149
< <server id="yk" address="127.0.0.1" port="6800"/> ---
> <server id="a" address="127.0.0.1" port="6801"/>
269a270 >
<stdout-log path="${resin.home}/log/stdout-cms.log" timestamp="[%Y-%m-%d %H:%M:%S.%s]" rollover-period="1D"/>
300c301
< <web-app id="/" root-directory="/home/yangkai/dir"/> ---
> <web-app id="/" root-directory="/data/touchcms"/>
[yangkai@mp2 conf]$ 其中84行的没必要修改。其中配置文件中，主要修改的，也就这些参数。
3.启动过程

三、小结
1.使用resin版本很重要，上面是使用resin3.1.8测试的结果，使用reisn3.0.*就不行，前者的http.sh是40行，后者是84行；前者的resin.conf是正常的，后者里面找不到：
<cluster id="app-tier"> <!-- 设置集群上下文的根, 相对于server.root --> <root-directory>.</root-directory> 也没有：
<!-- define the servers in the cluster --> 配置起来很麻烦。。。
2.其中如果对于方法的操作，resin的其启动与关闭，必须全部一起操作，否则就不会成功。这个是我测试的结果，开始我也以为不影响，调试了几个小时，最后发现是这个问题。也许是因为我某个地方配置不正确，谁知道请告诉我下，谢谢。
四、问题
关于性能上的问题，是使用一个resin使用不同的配置文件做集群性能好，还是安装多个resin性能好？如网站执行效率，服务器资源消耗等方面。
