Tomcat目录下的结构如图：
第一步：Tomcat默认空间webapps，中已经存在一个项目了，此时要增加一个项目运行可以将原本webapps目录copa一份，
改名为webapp1(或者其他看实际情况)，然后，将webapp1目录中原来的项目清除，加入你要部署的新项目
第二部：更改conf中的配置文件：server.xml
<?xml version='1.0' encoding='utf-8'?>
<Server port="8005" shutdown="SHUTDOWN"> <Listener className="org.apache.catalina.startup.VersionLoggerListener" /> <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" /> <Listener className="org.apache.catalina.core.JasperListener" /> <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" /> <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" /> <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" /> <GlobalNamingResources> <Resource name="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> <!-- 第一个项目 --> <Service name="Catalina"> <!-- 此端口为8087，其他项目端口不能有冲突 --> <Connector port="8087" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> <Engine name="Catalina" defaultHost="localhost"> <Realm className="org.apache.catalina.realm.LockOutRealm"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> </Realm> <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true"> <!-- 配置：项目名，项目路径 --> <Context docBase="testOne" path="/opt/tomcat7/webapps" reloadable="true" /> <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> </Host> <Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIpHeader="X-Forwarded-For" protocolHeader="X-Forwarded-Proto" protocolHeaderHttpsValue="https" /> </Engine> </Service> <!-- 第二个项目 --> <Service name="Catalina"> <!-- 此端口为8089，其他项目端口不能有冲突 --> <Connector port="8089" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> <Engine name="Catalina" defaultHost="localhost"> <Realm className="org.apache.catalina.realm.LockOutRealm"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> </Realm> <Host name="localhost" appBase="webapps1" unpackWARs="true" autoDeploy="true"> <!-- 配置：项目名，项目路径 --> <Context docBase="testTwo" path="/opt/tomcat7/webapps1" reloadable="true" /> <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> </Host> <Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIpHeader="X-Forwarded-For" protocolHeader="X-Forwarded-Proto" protocolHeaderHttpsValue="https" /> </Engine> </Service> </Server>第三部：重启Tomcat即可完成此时，
访问第一个项目的路径为：localhost:8087/testOne
访问第二个项目的路径为：localhost:8089/testTwo
附：
了解下tomcat的几个主要端口：
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="60000"
redirectPort="8443" disableUploadTimeout="false"
executor="tomcatThreadPool" URIEncoding="UTF-8"/>
其中8080为HTTP端口，8443为HTTPS端口。<Server port="8005" shutdown="SHUTDOWN">
8005为远程停服务端口 <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> 8009为AJP端口，APACHE能过AJP协议访问TOMCAT的8009端口。
