1、修改../tomcat/conf/server.xml，原有代码如下：

<Service name="Catalina"> <Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/> <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"/> <Engine defaultHost="localhost" name="Catalina"> <Realm className="org.apache.catalina.realm.LockOutRealm"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> </Realm> <Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true"> <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t "%r" %s %b" prefix="localhost_access_log." suffix=".txt"/> </Host> </Engine> </Service> |
2、添加新端口号，代码如下：
注意修改Service name; Connector port; Engine name; Host appBase
1 <Service name="Catalina1"> 2 3 <!--The connectors can use a shared executor, you can define one or more named thread pools--> 4 <!-- 5 <Executor name="tomcatThreadPool" namePrefix="catalina-exec-" 6 maxThreads="150" minSpareThreads="4"/> 7 --> 8 9 10 <!-- A "Connector" represents an endpoint by which requests are received 11 and responses are returned.

3、创建目录
a. 创建需要部署的目录../Tomcat/webapps1,并将需要部署的项目拷贝至该目录；
b. 创建配置文件目录../Tomcat/conf/Catalina1/localhost
4、修改项目代码
在我尝试的过程中发现一个比较容易出错的地方，就是最好修改web.xml和log4j.properties配置文件。
其中web.xml文件，需要添加webAppRootKey，代码如下：
|
1
2
3
4
5
|
//上层节点是web-app<context-param> <param-name>webAppRootKey</param-name> <param-value>mos_ms.root</param-value> </context-param> |
log4j.properties，修改log4j.appender.org.apache.log4j.DailyRollingFileAppender.File的值，代码如下：
|
1
2
3
|
//具体位置自定义，但是需要在${catalina1.home}中log4j.appender.A=org.apache.log4j.DailyRollingFileAppender log4j.appender.A.File=${catalina1.home}/logs/GYL_log/PurePro_ |
5、做好相应的改动
启动tomcat，webapps目录和webapps1目录的应用都会启动，可以根据不同的端口进行访问里面的项目；假设项目名称是MyApp，对于上述改动那么我们就可以使用以下地址访问：http://localhost:8080/MyApp 或者 http://localhost:8090/MyApp。
