Tomcat目錄下的結構如圖：

第一步：Tomcat預設空間webapps，中已經存在一個專案了，此時要增加一個專案執行可以將原本webapps目錄copa一份，

改名為webapp1(或者其他看實際情況)，然後，將webapp1目錄中原來的專案清除，加入你要部署的新專案

第二部：更改conf中的配置檔案：server.xml

<?xml version='1.0' encoding='utf-8'?>
<Server port="8005" shutdown="SHUTDOWN">

              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>
  <!-- 第一個專案 -->

    <!-- 此埠為8087，其他專案埠不能有衝突 -->

        <Context docBase="testOne" path="/opt/tomcat7/webapps" reloadable="true" />
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"

      </Host>  
      <Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIpHeader="X-Forwarded-For"
             protocolHeader="X-Forwarded-Proto" protocolHeaderHttpsValue="https" />
    </Engine>
  </Service>
  <!-- 第二個專案 -->

    <Connector port="8089" protocol="HTTP/1.1"

    <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：專案名，專案路徑 -->
        <Context docBase="testTwo" path="/opt/tomcat7/webapps1" reloadable="true" />        
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"

      </Host>
      <Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIpHeader="X-Forwarded-For"
             protocolHeader="X-Forwarded-Proto" protocolHeaderHttpsValue="https" />
    </Engine>
  </Service>
 
</Server>

第三部：重啟Tomcat即可完成

此時，

訪問第一個專案的路徑為：localhost:8087/testOne

訪問第二個專案的路徑為：localhost:8089/testTwo
