cdh集群ip更改

#—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) = (‘172.6.10.20′) where name=’dip001’;
update hosts set (ip_address) = (‘172.6.10.21′) where name=’dip002’;
update hosts set (ip_address) = (‘172.2.10.22′) where name=’dip003’;
update hosts set (ip_address) = (‘172.6.10.23′) where name=’dip005’;
update hosts set (ip_address) = (‘172.6.10.24′) where name=’dip006’;
update hosts set (ip_address) = (‘172.6.10.25′) where name=’dip007’;

–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=172.6.10.20

#–3重启元数据库mysql 
sysytemctl start mysqld

#–4启动server
/etc/init.d/cloudera-scm-server restart

#–5重启每个节点的agent

for i in {1,2,3,5,6,7} ; do ssh dip00$i ‘/etc/init.d/cloudera-scm-agent restart’;done

#–6进入172.6.10.20:7180页面，重启cdh集群和cloudera management服务
