同一个tomcat配置多个host

方法1，不需要修改context

在conf/server.xml添加host

<Host name="msg.xxx.com"  appBase="msg.xxx.com"
            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>

在tomcat里面添加msg.xxx.com文件夹，项目命名为ROOT就可以了。

方法2,需要同时配置context(本人没有配置成功)

<Host name="www.a.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
                <Context path="" docBase="root/tomcat/a" />
                <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="a_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
            </Host>
<Host name="www.b.com"  appBase="webapps1"
            unpackWARs="true" autoDeploy="true">
                <Context path="" docBase="/home/tomcat/b" />
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="b_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>
