回复： zookeeper 连接失败

Question

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

[hadoop@hadoop000 bin]$ ./zkCli.sh

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

  你看看你的IP是多少，然后再看看你的zk的日志IP是多少。明显你的机器的IP和hostname没改对。。。这么基础的Linux错误。。。学大数据之前建议Linux基础先抓抓。否则寸步难行

• 提问者 weixin_慕码人2413128 #2

  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

Answer 3

Michael_PK 2020-07-16 13:07:28

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

• 提问者 weixin_慕码人2413128 #1

  IP 那个问题我po在上面了 字数不够

Answer 4

Michael_PK 2020-07-16 12:57:07

你连接的时候加上参数让他使用hadoop000，别走localhost

• 提问者 weixin_慕码人2413128 #1

  hadoop 的ip 也是一个效果的
