[CDH] modify the default port 7180 of cloudera manager in cdh/cdp environment

Preface

Recently, it has been built in cooperation with the downstream CDP Cluster of environment , Because the testing party is the cloud environment , And require the Internet web Port can only be used 10000 above , therefore cloudera-manger default 7180 Need modification , because CM web The interface cannot be opened , So you can only modify the metabase , The metabase I use here is MySql.

Modification method

1. Sign in mysql database

mysql -h 15.5.4.51 -uroot -p

2. Switch database (CM Metabase of )

mysql> use scm;

Be careful ： Everyone's name , The names are inconsistent , Just use your own .

3. see configs_containers Table data

select * from configs_containers;

give the result as follows ：

+---------------------+-------------------------+-------------+-------------------+
| CONFIG_CONTAINER_ID | OPTIMISTIC_LOCK_VERSION | CONFIG_TYPE | CONFIG_GENERATION |
+---------------------+-------------------------+-------------+-------------------+
|                   1 |                       1 | ALL_HOSTS   |                 0 |
|                   2 |                      18 | SCM         |                 3 |
+---------------------+-------------------------+-------------+-------------------+

Record CONFIG_TYPE = SCM Of CONFIG_CONTAINER_ID value , I'm here for 2.

4. Yes config Table new http_port To configure

Be careful ： stay CDP Environment , http_port The default value of 7180, stay config There is no such record in the table . So we need to directly add , Another is to pay attention CONFIG_CONTAINER_ID To work with configs_containers Table corresponding upper . Otherwise, foreign key conflicts will be reported .

newly added http_port

INSERT INTO `CONFIGS` (`CONFIG_ID`, `ATTR`, `VALUE`, `CONFIG_CONTAINER_ID`) VALUES (635, 'http_port', '17180', 2);

Check whether the addition is successful

mysql> select * from CONFIGS where ATTR='http_port';
+-----------+---------+-----------+-------+------------+---------+---------------------+-------------------------+----------------------+
| CONFIG_ID | ROLE_ID | ATTR      | VALUE | SERVICE_ID | HOST_ID | CONFIG_CONTAINER_ID | OPTIMISTIC_LOCK_VERSION | ROLE_CONFIG_GROUP_ID |
+-----------+---------+-----------+-------+------------+---------+---------------------+-------------------------+----------------------+
|         635 |    NULL | http_port | 17180  |       NULL |    NULL |                   2 |                       0 |                 NULL |
+-----------+---------+-----------+-------+------------+---------+---------------------+-------------------------+----------------------+
1 row in set (0.00 sec)

5. Restart after modification cloudera-scm-server

systemctl restart cloudera-scm-server

6. Check whether the port has been modified successfully

netstat -tunlp|grep `ps -ef|grep cloudera-scm-server |grep -v grep |awk '{print $2}'`

Modification successful ！
