tomcat一个端口配置多个项目

在server.xml中增加host节点

<Host name="localhost"  appBase="webapps"   <!--这是默认的--->
            unpackWARs="true" autoDeploy="true">

        <!-- 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>

     <Host name="sin2x.com" appBase="/data/www/apps/sin2x"    <!--C盘host文件需要添加解析到 'sin2x.com' --->
            unpackWARs="true" autoDeploy="true">
        <Context path="" docBase="ROOT" reloadable="true"/>   <!--docBase可以写绝对路径，即已‘/’开头，不写绝对路径则从appBase路径开始算--->

            <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
                        prefix="sin2x.com_access_log" suffix=".txt"   <!--指定日志-->
                        pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>
