一个Resin配置多个集群应用[linux环境]

主要原理：通过一个RESIN配置多个WEB应用，实际上也就是利用resin做分发，分别将请求分发到RESIN配置的多个端口，（每一个端口类似另外启动一个RESIN）.

我用的是resin-pro-3.0.22_bl

假设现在配置：一个web-a 作为转发服务，然后配置两个app-a.sh和app-b.sh

web-a.sh

./bin/httpd.sh -conf ./conf/WebA.conf -server web-a -Xmn100M -Xms312M -Xmx512M -XX:PermSize=64M -XX:MaxNewSize=256m -XX:MaxPermSize=128m -Djava.awt.headless=true

红色部分表示运行的文件，然后加载/conf/WebA.conf文件

 

app-a.sh

./bin/httpd.sh -conf ./conf/APP-tier_log.conf -server app-a  -Xmn100M -Xms312M -Xmx512M  -XX:PermSize=64M -XX:MaxNewSize=256m -XX:MaxPermSize=128m -Djava.awt.headless=true

 

红色加粗地方文件：

WebA.conf 系统的转发配置文件

启动方式：

我的resin路径：usr:/resin-pro-3.0.22_bl

root$:cd usr:/resin-pro-3.0.22_bl/

root$:./web-a.sh

 

然后启动

root$:./app-a.sh

root$:./app-b.sh

 

然后就可以开始访问你的WEB页面了
