使用不同端口再tomcat部署两个相同项目

1.通过不同的端口来访问不同的目录

先看图：

就是上图画圈的地方，webapps复制两个，命名可以自己随便写名字，我是以端口命名。

第二，就是修改conf文件下的server.xml

<?xml version='1.0' encoding='utf-8'?>

<Server port="8054" shutdown="SHUTDOWN">
  <!-- Security listener. Documentation at /docs/config/listeners.html
  <Listener className="org.apache.catalina.security.SecurityListener" />
  -->
  <!--APR library loader. Documentation at /docs/apr.html -->
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <!--Initialize Jasper prior to webapps are loaded. Documentation at /docs/jasper-howto.html -->
  <Listener className="org.apache.catalina.core.JasperListener" />
  <!-- Prevent memory leaks due to use of particular java/javax APIs-->
  <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>


  <Service name="Catalina">


    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="9543" />

   
    <Connector port="8909" protocol="AJP/1.3" redirectPort="9543" />

    <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">

        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />
    <Context path="/route" reloadable="true" docBase="/home/develop/tomcat-7.0.54/flatrass"/>
      </Host>   
    </Engine>
    </Service>
 
     <Service name="Catalina">
     <!--把port改成8081-->
    <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="9543" />
 
    <Connector port="8909" protocol="AJP/1.3" redirectPort="9543" />
    <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"   ---这里要修改为修改后的webapps名称
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />
        <Context  path="/route" reloadable="true" docBase="/home/develop/tomcat-7.0.54/flatrasweats"/>
      </Host>
    </Engine>
  </Service>
</Server>

1.1上面主要的是复制一份 <service>并修改访问的端口和访问的目录

2.使用不同的webAppRootKey来区分相同的项目

 项目A，B(B 是A 的复制)

若把A，B工程同时部署到tomcat下，会发生只能访问A，B工程中的其中一个，而另一个会出现404错误(或者无法访问)，此时可参照如下方法解决：

步骤1：找到工程下的web.xml文件

步骤2：修改webAppRootKey的属性，使得两工程的不一致便可

A工程的webAppRootKey属性如下：

<context-param>
<param-name>webAppRootKey</param-name>
<param-value>mywebtest.root1</param-value>
</context-param>

B工程的webAppRootKey属性如下：

<context-param>
<param-name>webAppRootKey</param-name>
<param-value>myweb.root1</param-value>
</context-param>

请注意，若A，B工程的web.xml文件下没有此属性，则加上便可。
