CDH6集群迁移（IP地址更改）操作文档

1、更改IP地址：

vi /etc/sysconfig/network-scripts/ifcng-ens33

2、更改host:

vi /etc/hosts

3、server节点上修改MySQL数据库，

mysql -u root -p
use scm;
select * from HOSTS;
update HOSTS set ip_address= ‘172.31.134.100’ where host_id=1;
update HOSTS set ip_address= ‘172.31.134.101’ where host_id=2;
update HOSTS set ip_address= ‘172.31.134.104’ where host_id=3;
update HOSTS set ip_address= ‘172.31.134.103’ where host_id=4;
update HOSTS set ip_address= ‘172.31.134.102’ where host_id=5;

4、更改agent配置

vi /etc/cloudera-scm-agent/config.ini

5、更改yum仓库地址

如果yum仓库用的是IP地址，那就要改一下（改server节点即可，保险起见最好每个节点都改一下）：
vi /etc/yum.repos.d/cloudera-manager.repo
yum clean all
yum makecache

6、检查ntp配置

检查server地址是否需要更改
vi /etc/ntp.conf
