由于技术研发部在开发三期业务时没有考虑到与二期业务的兼容性，为了保证三期业务上线时不影响二期用户客户端的使用，需要在同一tomcat下部署两个工程。但由于这两个工程之间需要相互调用，据博主测试这两个工程如果再同一端口下运行时总会有一个工程无法正常请求另一个工程的业务（研发部门未经测试直接交付实施上线【太可怕了】），所以在部署业务时，笔者为了保证业务按时上线采用了在一个Tomcat配置多个端口号以对应不同服务完成业务的正常交付。

一、在Tomcat下配置多个服务，用不同的端口号。下面以增加1个端口号为例。具体实施步骤如下所示：

第一步、修改 vi /webapp/tomcat6/conf/server.xml文件

具体修改内容如下：

<?xml version='1.0' encoding='utf-8'?>
<Server port="8005"shutdown="SHUTDOWN">
    <Resourcename="UserDatabase" auth="Container"
             type="org.apache.catalina.UserDatabase"
             description="User database that can be updated and saved"
             factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
             pathname="conf/tomcat-users.xml" />
 </GlobalNamingResources>
  <Servicename="Catalina">
    <Connectorport="8080" protocol="HTTP/1.1"
              connectionTimeout="20000"
              redirectPort="8443" />
      <RealmclassName="org.apache.catalina.realm.UserDatabaseRealm"
            resourceName="UserDatabase"/>
      <Hostname="localhost" appBase="webapps"
           unpackWARs="true" autoDeploy="true"
           xmlValidation="false" xmlNamespaceAware="false">
<Context path=""  docBase="/webapp/tomcat6/webapps/sdmp/"reloadable="true" ></Context>
      </Host>
    </Engine>
  </Service>
<!—此次向下开始添加新的端口服务-->
  <!-- add byfengzhanhai on 2013 -->
  <Servicename="Catalinai">
<!—service name 必须要修改成与原servicename不一致-->
    <Connectorport="8090" protocol="HTTP/1.1"
              connectionTimeout="20000"
               redirectPort="8443" />
<!—端口号 必须修改-->
    <Connectorport="8010" protocol="AJP/1.3"redirectPort="8443" />
      <RealmclassName="org.apache.catalina.realm.UserDatabaseRealm"
            resourceName="UserDatabase"/>
      <Hostname="localhost" appBase="webapp"
           unpackWARs="true" autoDeploy="true"
           xmlValidation="false" xmlNamespaceAware="false">
<!—appBase name 必须要修改-->
<Context path=""  docBase="/webapp/tomcat6/webapp/mbp/"reloadable="true" ></Context>
<!—docBase 调整至相应appBase属性 保证前方代理访问端口号自动调整到该服务-->

      </Host>
    </Engine>
  </Service>
</Server>
<!--注意Service name、Engine name、appBase，端口号别忘了修改，以免重复无法启动 -->
第二步、在/webapp/tomcat6创建相应的部署目录 
 [root@localhosttomcat6]# mkdir webapp
 同时将工程发布到的新建的部署目录 中
 第三步、创建配置文件目录和配置文件 1）进入相应目录
 [root@localhost tomcat6]# cd /webapp/tomcat6/conf
2）创建目录
 [root@localhost conf]# mkdir Catalinai
3）拷贝配置文件
[root@localhostconf]# cp -r ./Catalina/localhost/ ./Catalinai
4）验证以上操作的正确性
[root@localhostconf]# cd Catalinai/
 [root@localhost Catalinai]# cd localhost/
[root@localhostlocalhost]# pwd
/webapp/tomcat6/conf/Catalinai/localhost
[root@localhostlocalhost]# ls
host-manager.xml  manager.xml
第四步、重启tomcat服务并验证相应端口服务已经正常运行
1)      lsof–i:8080
2)      lsof–i:8090
如果返回相应java进程则证明配置无误。
二、附tomcat前端Nginx代理相关的调整和配置
