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

  No SQLite environment is required when using SQLite to store Dashboard metadata.

• Before the installation starts, the following ports are not occupied.

  Port	Description
  7005	The port through which Dashboard Enterprise Edition provides the web service.
  9090	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 aumatically 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.
