网上查找关键词 严重: Unable to start cluster.
org.apache.catalina.tribes.ChannelException: java.lang.IllegalArgumentException: java.net.UnknownHostException: auto; No faulty members identified. 后查找到 可能原因是server.xml文件出错了，于是尝试修改如下：

  <ReceiverclassName="org.apache.catalina.tribes.transport.nio.NioReceiver"
  address="auto"     //把这个改为localhost或都自己的ip都可以；如果用auto的话，在vmware里会与主机的实际ip产生冲突，原因不知道是什么，呵呵。
  port="4000"
  autoBind="100"
  selectorTimeout="5000"
  maxThreads="6"/>

参考文章：http://www.linuxidc.com/Linux/2011-08/39833.htm
修改后重启Tomcat

重启后可以看到虽然还是有报错，但是错误明显少了很多，于是输入 http://localhost:10001进行验证（10001为自己设置的端口）
依然不成功，想了想恍然大悟，可能是防火墙没关
service iptables status查看防火墙状态，果然是防火墙没关
service iptables stop
再次验证 哈哈！ 成了
友情提示：经常会忘关防火墙，所以有问题多想想防火墙有没有关
此问题还需再研究 但是目前暂时算解决了吧
