[GitHub] [incubator-dolphinscheduler] nboding opened a new issue #2409: [BUG] zk中masters注册ip127.0.0.1
nboding opened a new issue #2409: [BUG] zk中masters注册ip127.0.0.1
URL: https://github.com/apache/incubator-dolphinscheduler/issues/2409
*For better global communication, please give priority to using English description, thx! *
**Describe the bug**
bug : zookeeper masters znode list ip address is 127.0.0.1，instead of wanted ip eth0 or eth1
chinese describe：zk中注册的master信息ip地址是127.0.0.1，而不是配置的域名所对应或者解析的ip地址。官网文档中建议在/etc/hosts中注释掉127.0.0.1这条解析，我觉得不合适。
**To Reproduce**
Steps to reproduce the behavior, for example:
1、zookeeper znode info：
[zk: localhost:2181(CONNECTED) 6] ls /dolphinscheduler/masters
[127.0.0.1]
2、ds install_config info：
installPath=/usr/local/dolphinscheduler
deployUser=dolphinscheduler
ips=ds1
sshPort=60022
masters=ds1
workers=ds1
alertServer=ds1
apiServers=ds1
3、/etc/hosts info
$cat /etc/hosts
127.0.0.1 localhost hadoop1
10.3.57.15 ds1 hadoop1
**Expected behavior**
A clear and concise description of what you expected to happen.
**Screenshots**
If applicable, add screenshots to help explain your problem.
**Which version of Dolphin Scheduler:**
1.2.1
**Additional context**
**Requirement or improvement
- Please describe about your requirements or improvement suggestions.
bug fix try:
1、confirm hostname
$hostname
hadoop1
2、hostname -i
127.0.0.1 10.3.57.15
3、edit /etc/hosts,delete hadoop1 from 127.0.0.1 record
$cat /etc/hosts
127.0.0.1 localhost
10.3.57.15 ds1 hadoop1
4、hostname -i
10.3.57.15
it is ok
chinese describe:
hostname命令返回的服务器主机名，hostname -i 返回的是服务器主机名在/etc/hosts中所有匹配的ip地址 所以我把/etc/hosts中127.0.01中的主机名删掉，只保留内网ip的解析就可以了，没必要把127.0.0.1整条注释掉, 只要hostname命令返回值 在/etc/hosts中对应的内网ip正确就可以，ds程序肯定是取了第一个值，我理解上ds程序不应该用hostname -i 取值这样有点问题，因为好多公司服务器的主机名都是运维配置的，感觉还是直接取配置文件的域名解析的返回ip更准确，或者znode中存域名信息而不是ip addr。

问下楼主，你是如何配置实现注册到zk的是ip的？我找了文档，也没找到相关配置。我这里只能注册hostname过去，这样导致的问题是，在k8s集群里部署，master跟worker无法通讯
