我正在尝试在我们的 unix 机器上安装一个 Tomcat 服务器（远程访问），该服务器将用于测试项目。

我用过Tomcat 5.0.25（因为我们的产品使用的是相同的版本）。

现在我不想通过 Apache 运行它，而只想直接访问 tomcat。

所以我已经部署了 Tomcat 并配置了 server.xml（见下文），但是当我启动它时，我无法使用这个 URL 看到 tomcat 5 欢迎页面：global.int.com:9082

<?xml version='1.0' encoding='utf-8'?>

<Server port="9007" shutdown="SHUTDOWN">

  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener"
            debug="0"/>
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener"
            debug="0"/>

  <!-- Global JNDI resources -->
  <GlobalNamingResources>

    <!-- Test entry for demonstration purposes -->
    <Environment name="simpleValue" type="java.lang.Integer" value="30"/>

    <!-- Editable user database that can also be used by
         UserDatabaseRealm to authenticate users -->
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
       description="User database that can be updated and saved">
    </Resource>
    <ResourceParams name="UserDatabase">
      <parameter>
        <name>factory</name>
        <value>org.apache.catalina.users.MemoryUserDatabaseFactory</value>
      </parameter>
      <parameter>
        <name>pathname</name>
        <value>conf/tomcat-users.xml</value>
      </parameter>
    </ResourceParams>

  </GlobalNamingResources>

  <Service name="Catalina">

    <!-- An Engine represents the entry point (within Catalina) that processes

    <!-- You should set jvmRoute to support load-balancing via AJP ie :

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

      <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
             resourceName="UserDatabase"/>

      <!-- Define the default virtual host
           Note: XML Schema validation will not work with Xerces 2.2.
       -->
      <Host name="localhost"  appBase="webapps"

            xmlValidation="false" xmlNamespaceAware="false">

      </Host>
    </Engine>
  </Service>
</Server>

我可以看到 Tomcat 正在运行，Catalina.out 说：

Jan 27, 2012 8:21:56 PM org.apache.coyote.http11.Http11Protocol start INFO: Starting Coyote HTTP/1.1 on http-9082 Jan 27, 2012 8:21:56 PM org.apache.jk.common.ChannelSocket init INFO: JK2: ajp13 listening on /0.0.0.0:9020 Jan 27, 2012 8:21:56 PM org.apache.jk.server.JkMain start INFO: Jk running ID=0 time=1/14 config=/home/tomcat/tomcat5_fcl_uat/conf/jk2.properties Jan 27, 2012 8:21:56 PM org.apache.catalina.startup.Catalina start INFO: Server startup in 2173 ms

和命令 lsof -i TCP显示：

java 29923 tomcat 5u IPv6 373023 TCP *:9082 (LISTEN)

我不知道为什么我看不到 tomcat 页面。我在端口 9081 上运行了另一个 Tomcat 服务器，我们可以使用 url 访问它global.int.com:9081 ，上面的 server.xml 是它的副本，除了端口号被更改。谁能给我一个关于事情在哪里分崩离析的提示。谢谢

更新2：

远程桌面wget -S的结果：

以下是wget -S在LocalHost 机器上的结果：

更新3：结果iptables -L -v -n：

  106  5920 ACCEPT     tcp  --  *      *       10.0.0.0/8           0.0.0.0/0           tcp dpt:8080
    6   312 ACCEPT     tcp  --  *      *       10.0.0.0/8           0.0.0.0/0           tcp dpt:8180
    0     0 ACCEPT     tcp  --  *      *       10.0.0.0/8           0.0.0.0/0           tcp dpt:9080

如果我错了，请纠正我 - 但上面的结果显示了我无法访问 tomcat 的原因，因为我已将端口 9082 分配给 tomcat 并且该端口在上面的列表中不存在。

中使用的所有端口号server.xml都是唯一的（我已经仔细检查过）。关于为什么我无法看到 Tomcat 主页以及如何修复它的任何建议？

原来这是阻止传入连接的防火墙问题。iptables -L -v -n（在 Linux 上）有助于揭示实际问题。有关详细信息，请参阅文章下方的评论。
