多开Tomcat，以及Tomcat把服务器上的硬盘路径映射成虚拟

以下我们来配一个8081tomcat

<!-- A "Connector" represents an endpoint by which requests are received
         and responses are returned. Documentation at :
         Java HTTP Connector: /docs/config/http.html
         Java AJP  Connector: /docs/config/ajp.html
         APR (HTTP/AJP) Connector: /docs/apr.html
         Define a non-SSL/TLS HTTP/1.1 Connector on port 8080
    -->
    <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8444" />

<!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8010" protocol="AJP/1.3" redirectPort="8444" />

如果想把服务器上的硬盘路径映射成虚拟路径，需要在<Host>里面配<Context>

<Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
            
            <Context path="/files" docBase="D:\wechat\files" reloadable="true" debug="0"></Context>
            <Context path="/images" docBase="D:\wechat\images" reloadable="true" debug="0"></Context>

        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->

        <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html
             Note: The pattern used is equivalent to using pattern="common" -->
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

      </Host>
