tomcat配置域名

1.1、测试环境说明：

Linux版本：7.6

IP地址：10.11.220.123/24

Tomcat版本：tomcat-8.5.37(端口号为8080)

Jdk版本：1.8.0_202

1.2、配置tomcat server.xml 文件(Engine组件，标红的部分是需要修改的内容)：

  <!--For clustering, please take a look at documentation at:

      /docs/cluster-howto.html  (simple how to)

      /docs/config/cluster.html (reference documentation) -->

  <!--

  <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

  -->



  <!-- Use the LockOutRealm to prevent attempts to guess user passwords

       via a brute-force attack -->

  <Realm className="org.apache.catalina.realm.LockOutRealm">

    <!-- This Realm uses the UserDatabase configured in the global JNDI

         resources under the key "UserDatabase".  Any edits

         that are performed against this UserDatabase are immediately

         available for use by the Realm.  -->

    <Realm className="org.apache.catalina.realm.UserDatabaseRealm"

           resourceName="UserDatabase"/>

  </Realm>



  <Host name="www.tomcat8080.com"  appBase="webapps"

        unpackWARs="true" autoDeploy="true">

  <!-- 真实使用的虚拟目录，域名也是你指定的域名 -->



    <!-- 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" />

  <!-- <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127.0.0.1" deny=""/> -->

  </Host>



  <Host name="VirtualHost"  appBase="VirtualHostDir"

        unpackWARs="true" autoDeploy="true">

  </Host>

  <!-- 建立一个虚假的虚拟目录VirtualHostDir，这个目录是不存在的，当访问IP地址或其他域名，将被转向到访问这个虚拟空目录上。VirtualHostDir目录如果不存在会自动创建 -->

提示：tomcat在启动的情况下修改server.xml 文件后需要重启tomcat实例使配置生效。

2、在widows电脑的C:\Windows\System32\drivers\etc\hosts文件中添加解析记录如下：

10.11.220.123 www.tomcat8080.com
