Tomcat 多个虚拟主机配置方法

conf/server.xml

移除注释内容后，类似内容如下：

<Server>
  ……
  ……
  ……
  <Service name="Catalina">
    <Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
    <Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
             resourceName="UserDatabase"/>
      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
      </Host>
    </Engine>
  </Service>
</Server>

多个虚拟主机的配置，即增加 <service> 或 <host> 标签段。

一、端口方式：<Service>

在</Service>与</Server>之间增加

      </Host>
    </Engine>
  </Service>
  
  <!-- 虚拟主机：端口方式  须修改三个地方： Service name / Connetor port / Host appBase
　　　　　　　　appBase可为相对路径，也可为绝对路径
  -->
  
  <Service name="Catalina2">
    <Connector port="6038" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="6444" />
    <Connector port="6010" protocol="AJP/1.3" redirectPort="6444" />
    <Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
                    resourceName="UserDatabase"/>
      <Host name="localhost"  appBase="webapps2"
                    unpackWARs="true" autoDeploy="true"
                    xmlValidation="false" xmlNamespaceAware="false">
      </Host>
    </Engine>
  </Service>
</Server>

http://localhost:8080/

http://locathost:6037/

二、域名方式：<Host>

 在</Host>与</Engine>之间增加

      </Host>
      <!--虚拟主机：域名方式，需修改 Host name/appBase
      -->
      <Host name="a.b.c"  appBase="webapps2"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
      </Host>
    </Engine>
  </Service>
</Server>

http://locathost:8080/

http://a.b.c:8080/
