老师你好
我把日志的等级调到DEBUG后

zookeeper.out 的输出并没有变化

然后我用zkcli.sh 连接了下错误还是之前的报错
找不出问题

老师牛逼 ,我正打算问你是不是这个原因呢。我在操作的时候，无论怎么修改，原来的那个inet就一直都是172.0.01 修改不了然后我就自己google了下解决办法 sudo -i , 然后 dhclient -v 下然后

ifconfig 的界面就变成

然后就可以上网了是这里影响了吗

对不起老师耽误您时间了。没学过计算机网络不知道网段的意思，把ip设成跟自己电脑一个ip所以不行，非常感谢您耐心的解答，万分感谢

有个问题我有点好奇，那个IP是199.233的这个好像是我录课网络内网的IP，难道你的真正使用IP也是这个？你这个IP的话，Linux上能上网不

IP 那个问题我po在上面了字数不够

你连接的时候加上参数让他使用hadoop000，别走localhost

hadoop 的ip 也是一个效果的
