# 修改ip #

开始是在公司使用桥接模式，回到家使用无线网段变了，遂改掉IP,CDH中还是配置的原来的IP，需要改掉

## 停服务 ##

[root@node01 ~]# service cloudera-scm-agent stop
    [root@node01 ~]# service cloudera-scm-server stop

## 进入mysql修改元数据ip ##

mysql -u root -p123

MariaDB [cm]> select host_id, host_identifier, name, ip_address from HOSTS;
    +---------+--------------------------------------+--------+--------------+
    | host_id | host_identifier                      | name   | ip_address   |
    +---------+--------------------------------------+--------+--------------+
    |       1 | 912f0256-f551-4b04-b314-0f7506c8ece7 | node01 | 192.168.1.81 |
    |       2 | aafbe8a2-44a5-43b0-8b8b-b789cfed2f56 | node02 | 192.168.1.82 |
    |       3 | 187eb2a6-1c71-4614-82f3-21ca82105e07 | node03 | 192.168.1.83 |
    +---------+--------------------------------------+--------+--------------+

## 修改各主机的ip（分别修改各主机的ip） ##

MariaDB [cm]> update HOSTS set ip_address='192.168.206.81' where host_id='1'
        -> ;
    Query OK, 1 row affected (0.00 sec)

    MariaDB [cm]> update HOSTS set ip_address='192.168.206.82' where host_id='2'

    MariaDB [cm]> update HOSTS set ip_address='192.168.206.83' where host_id='3';

    # Port that the CM server is listening on.
    server_port=7182

## 重启服务 ##

[root@node01 ~]# systemctl start cloudera-scm-agent.service
    [root@node01 ~]# systemctl restart cloudera-scm-server
