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 is utf8.

    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

  1. Select and download the TAR package according to your needs. It is recommended to select the latest version.

  2. 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/

  3. Enter the extracted folder and modify the config.yaml file in the etc directory to set the LicenseManagerURL parameter to the host IP and port number 9119 where the License Manager (LM) is located and to set the relevant configuration.

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 the logs 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 is console.
    access.log Access log.
    It takes effect only when the Log.Mode in the Dashboard configuration is file.
    error.log Error log.
    It takes effect only when the Log.Mode in the Dashboard configuration is file.
    severe.log Severe log.
    It takes effect only when the Log.Mode in the Dashboard configuration is file.
    slow.log Slow log.
    It takes effect only when the Log.Mode in the Dashboard configuration is file.
    stat.log Statistic log.
    It takes effect only when the Log.Mode in the Dashboard configuration is file.

  • 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
