本文主要是介绍cdh集群迁移 ip更改，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
#---1.修改每个用户的hosts
vi /etc/hosts
#127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.6.10.20 dip001
172.6.10.21 dip002
172.6.10.22 dip003
172.6.10.23 dip005
172.6.10.24 dip006
172.6.10.25 dip007
#分发到每个节点
for i in {2,3,5,6,7} ;do scp /etc/hosts dip00$i:/etc ;done
--2修改node对应ip
登录mysql的scm库，修改hosts表
use scm；
update HOSTS set ip_address = '172.6.22.15' where name='dip0001';
update HOSTS set ip_address = '172.6.22.16' where name='dip0002';
update HOSTS set ip_address = '172.6.22.17' where name='dip0003';
update HOSTS set ip_address = '172.6.22.18' where name='dip0004';
update HOSTS set ip_address = '172.6.22.20' where name='dip0005';
update HOSTS set ip_address = '172.6.22.21' where name='dip0006';
update HOSTS set ip_address = '172.6.22.11' where name='dip0007';
--3修改每台cloudera-scm-agent的配置文件 server_host到cloudera-scm-server的ip
vi /etc/cloudera-scm-agent/config.ini
server_host=172.6.22.15
#--4重启cm客户端服务
systemctl restart cloudera-scm-agent
#--5重启cm主节点的server服务
systemctl restart cloudera-scm-server
#--6进入172.6.10.20:7180页面，重启cdh集群和cloudera management服务
