The GBase 8a MPP Database Operation Management System (GDOM) is a B/S architecture tool designed to provide full lifecycle operation and maintenance (O&M) support for the GBase 8a MPP database. It offers a range of functionalities including cluster management, host management, health checks, and alerts, all aimed at reducing customer O&M costs, improving efficiency, and ensuring 24/7 operation of the cluster.
GDOM Environment Setup Checklist
| Server | Installed Components | Node Type | Remarks |
|---|---|---|---|
| 10.0.0.211 | nginx, gdom-service | Deployment | |
| 10.0.0.212 | haproxy | Installation | Optional |
| 10.0.0.213 | mysql | Installation | |
| 10.0.0.214 | mysql | Installation | Optional |
| 10.0.0.215 | Redis, RocketMQ | Installation |
Note: Node Types
- Deployment Node: This is where the GDOM installation package is deployed. GDOM installation, service start/stop, uninstallation, and status queries are all managed from this node. It is the special installation node for managing GDOM services.
- Installation Node: This is the server for installing GDOM components. For high availability configuration, if deploying with a single node, ignore the optional nodes.
1. Unpacking the Installation Package
1.1. On the 10.0.0.211 machine, use the root user to unpack the package:
[root@nginx_gdom-service /opt]# tar -xf GDOM-v3.0.0-build1.2.tar.gz
2. Set Up User Trust
2.1. Prerequisite: Configure demo.options to specify the servers requiring mutual trust.
Edit demo.options:
vim /opt/GDOM-v3.0.0-build1.2/demo.options
Example configuration:
gdomRoot=/opt/gdom
gdomService=10.0.0.211
gdomServicePort=8080
user=gdom
gdomDb=10.0.0.213,10.0.0.214
gdomDbPort=3306
gdomDbUrl=
gdomDbUser=root
gdomDbPwd=1
gdomDbHa=10.0.0.212
gdomDbHaPort=3307
gdomDbHaMonitorPort=8811
gdomDbHaMonitorAdmin=admin
gdomDbHaMonitorPwd=admin
gdomNginx=10.0.0.211
gdomNginxPort=8810
gdomNginxUrl=
gdomRedis=10.0.0.215
gdomRedisPort=7481
gdomRedisDb=0
gdomRedisUrl=
gdomMq=10.0.0.215
gdomMqPort=9876
gdomDashBoardPort=9898
gdomMqUrl=
2.2. Execute on all machines:
useradd gdom
passwd gdom
su - gdom
ssh-keygen -t rsa -P ''
ssh-copy-id *.*.*.*
3. Set Up Auto Start (Optional)
3.1. On the deployment machine:
[root@nginx_gdom-service ~]# vim /etc/rc.local
Add the following configuration:
#!/bin/sh -e
/opt/GDOM-v3.0.0-build1.2/gdomStart.sh -a
exit 0
Explanation:
-
/opt: The parent directory where the GDOM installation package is unpacked. -
GDOM-v3.0.0-build1.2: The directory where the GDOM installation package is unpacked. -
gdomStart.sh -a: The one-click start script for GDOM.
4. GDOM Deployment
4.1. Note: Ensure that the user has permission to operate on the GDOM root directory on all nodes.
On all machines, execute:
mkdir /opt/gdom
chown -R gdom.gdom /opt/gdom
4.2. On the deployment machine, run the installation script:
[root@nginx_gdom-service /opt/GDOM-v3.0.0-build1.2]# su - gdom
[gdom@nginx_gdom-service /opt/GDOM-v3.0.0-build1.2]# sh gdomInstall.sh -a
5. Start GDOM Service
5.1. On the deployment machine, start the service:
[gdom@nginx_gdom-service /opt/GDOM-v3.0.0-build1.2]$ sh gdomStart.sh -a
5.2. After starting the service, access the browser:
- URL:
http://10.0.0.211:8810 - Default Username:
admin - Default Password:
admin123
To stop the service:
sh gdomStop.sh -a
To check the service status:
sh gdomStatus.sh -a

gdomMqUrl=
Note: MySQL, Redis, RocketMQ, and Nginx are optional components.
If the user’s environment already has these components, configure their URL properties in demo.options. Regardless of whether they are newly installed or already present, the ports need to be configured.
For the best results, it is recommended to do a fresh installation to avoid conflicts with existing middleware.
With GDOM, you can ensure efficient O&M operations, simplified management, and seamless service monitoring for your GBase 8a deployment. Happy managing!
