Deploy Dashboard Enterprise Edition¶
This topic will introduce how to deploy Dashboard Enterprise Edition in detail.
Prerequisites¶
Before deploying Dashboard Enterprise Edition, you must do a check of these:
- Select and download Dashboard Enterprise Edition of the correct version. For information about the version correspondence between Dashboard Enterprise Edition and NebulaGraph, see Version compatibility.
-
MySQL and SQLite are supported to store Dashboard metadata. To use MySQL, make sure that the environment of MySQL is ready and a MySQL database named as
dashboard
is create. Make sure the default character set of the database isutf8
.Note
To store Dashboard metadata using SQLite, there is no need to configure the SQLite environment because SQLite is built-in to Dashboard.
-
Before the installation starts, the following ports are not occupied.
Port Description 7005 The port through which Dashboard Enterprise Edition provides the web service. 9091 The port of the prometheus service. 9200 The port of the nebula-stats-exporter service. 9093 The port of the Alertmanager service, used to receive Prometheus alerts and then send them to Dashboard. 9100 The port of the node-exporter service. The node-exporter is automatically deployed on the target machine after a cluster is created or imported. It is used to collect the source information of machines in the cluster, including the CPU, memory, load, disk, and network.
Enterpriseonly
You can apply online for Dashboard Enterprise Edition free trial. NebulaGraph Dashboard Enterprise Edition is available exclusively through our Enterprise Edition package and is not sold separately. Contact us for details.
Deploy Dashboard Enterprise Edition with TAR¶
Installation¶
-
Select and download the TAR package according to your needs. It is recommended to select the latest version.
-
Use
tar -xzvf
to decompress the TAR package.tar -xzvf nebula-dashboard-ent-<version>.linux-amd64.tar.gz -C <install_path>
For example:
tar -xzvf nebula-dashboard-ent-3.5.0.linux-amd64.tar.gz -C /usr/local/
-
Enter the extracted folder and modify the
config.yaml
file in theetc
directory to set theLicenseManagerURL
parameter to the host IP and port number9119
where the License Manager (LM) is located and to set the relevant configuration.Name: dashboard-api Host: 0.0.0.0 # Specifies the address segment that can access Dashboard.

Start Dashboard.
You can use the following command to start the Dashboard with one click.
cd /usr/local/nebula-dashboard-ent/scripts sudo ./dashboard.service start all
Or execute the following commands to start prometheus, webserver, nebula-stats-exporter and alertmanager services to start Dashboard.
cd scripts sudo ./dashboard.service start prometheus # Start prometheus service sudo ./dashboard.service start webserver # Start webserver service sudo ./dashboard.service start exporter # Start nebula-stats-exporter service sudo ./dashboard.service start alertmanager # Start alertmanager service
Note
If you change the configuration file after starting Dashboard, you can run dashboard.service restart all
in the scripts
directory to synchronize the changes to the Dashboard client page.

-
Run the following commands to view the status of and start all the services.
sudo systemctl list-dependencies nebula-dashboard.target # View the status of all the services. sudo systemctl start nebula-dashboard.target # Start all the services.
You can also view, start, and stop a single service.
sudo systemctl {status|stop|start} {nbd-prometheus.service|nbd-alert-manager.service|nbd-stats-exporter.service|nbd-webserver.service}
Uninstallation¶
To uninstall Dashboard Enterprise Edition, run the following command.
sudo dpkg -r <package_name>
Manage services in Dashboard¶
The following section presents two methods for managing the Dashboard service. It's important to note that these methods are not interchangeable. For instance, you can't start the service using the dashboard.service
script and then use the systemctl
command to stop it.
-
You can use the
dashboard.service
script to start, restart, stop, and check the Dashboard services.sudo <dashboard_path>/scripts/dashboard.service [-v] [-h] [-version] <start|restart|stop|status> <prometheus|webserver|exporter|gateway|all>
Parameter Description dashboard_path
Dashboard installation path. -v
Display detailed debugging information. -h
Display help information. -version
Display the Dashboard version. start
Start the target services. restart
Restart the target services. stop
Stop the target services. status
Check the status of the target services. prometheus
Set the prometheus Service as the target service. webserver
Set the webserver Service as the target service. exporter
Set the exporter Service as the target service. gateway
Set the gateway Service as the target service. all
Set all the Dashboard services as the target services. For example, if Dashboard is installed in the current directory, you can manage its services using the following commands:
sudo /dashboard/scripts/dashboard.service start all # Start Dashboard. sudo /dashboard/scripts/dashboard.service stop all # Stop Dashboard. sudo /dashboard/scripts/dashboard.service status all # Check Dashboard status. sudo /dashboard/scripts/dashboard.service restart all # Restart Dashboard.
-
If you installed Dashboard using RPM or DEB packages, you can manage the service using systemd. You can start, view, restart and stop the service using the
systemctl
command.sudo systemctl start nebula-dashboard.target # Start all service. sudo systemctl status nebula-dashboard.target # Check Dashboard status. sudo systemctl restart <nbd-prometheus.service|nbd-alert-manager.service|nbd-stats-exporter.service|nbd-webserver.service> # Restart service respectively. sudo systemctl stop <nbd-prometheus.service|nbd-alert-manager.service|nbd-stats-exporter.service|nbd-webserver.service> # Stop service respectively.
For example, to stop the Prometheus service, run the following command:
sudo systemctl stop nbd-prometheus.service
View logs¶
-
Users who manage services using
dashboard.service
can view the Dashboard Enterprise Edition logs in thelogs
directory.For example:
cat logs/prometheus.log
The descriptions of the log files are as follows.
Log file Description alertmanager.log
Alertmanager service log. nebula-stats-exporter.log
nebula-stats-exporter service log. prometheus.log
Prometheus service log. br
Backup and restore service log. webserver.log
Dashboard service log. It takes effect only when the Log.Mode
in the Dashboard configuration isconsole
.access.log
Access log. It takes effect only when the Log.Mode
in the Dashboard configuration isfile
.error.log
Error log. It takes effect only when the Log.Mode
in the Dashboard configuration isfile
.severe.log
Severe log. It takes effect only when the Log.Mode
in the Dashboard configuration isfile
.slow.log
Slow log. It takes effect only when the Log.Mode
in the Dashboard configuration isfile
.stat.log
Statistic log. It takes effect only when the Log.Mode
in the Dashboard configuration isfile
.
-
Users managing services with systemd can access the logs for each Dashboard Enterprise Edition service through
journalctl
.journalctl -u {nbd-prometheus.service|nbd-alert-manager.service|nbd-stats-exporter.service|nbd-webserver.service} -b
For example, to view the logs of the Prometheus service:
journalctl -u nbd-prometheus.service -b
