想实现更多的应用服务添加相应的service即可，注意service name不能相同，端口不能相同。
此时还没有弄完，首先在应用服务的根目录下找到WEB-INF文件夹，修改该目录下web.xml中的参数webAppRootKey的值，使得两个应用服务中的值不同就可以。如下：
<context-param>
<param-name>webAppRootKey</param-name>
<param-value>cnet2.webroot</param-value> //修改这个值。
</context-param>
然后，在加大JVM的对大小。可以通过修改tomcat目录下的bin目录中的catalina.bat文件。添加如下参数：（参数仅供参考）Xms是最小堆大小，Xmx是最大堆大小，一般修改这两个参数就ok了。
set JAVA_OPTS=-Xms512m -Xmx1300m -server -XX:PermSize=64M -XX:MaxPermSize=128m
set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=16688 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false
