# Deploy NebulaGraph Exchange

Download the NebulaGraph Exchange package and deploy its Spark environment. Run the commands below on the Linux machine that will run NebulaGraph Exchange.

## Prerequisites

- An x86-64 or ARM64 Linux machine.
- Java 8 installed, with the `java` and `tar` commands available, as required by [Spark 2.4.7](https://archive.apache.org/dist/spark/docs/2.4.7/).

Check the Java version:

````
java -version

````

Continue once the version is `1.8.x`.

## Download the package

Current version: 5.3.0. [Download the package](https://dev-docs.nebula-graph.io/downloads/exchange/5.3.0/nebula-graph-exchange-5.3.0.tgz), or run:

````
curl -fL -o nebula-graph-exchange-5.3.0.tgz \
  "https://dev-docs.nebula-graph.io/downloads/exchange/5.3.0/nebula-graph-exchange-5.3.0.tgz"

````

The package includes dependencies for both x86-64 and ARM64. To check file integrity, download its [SHA-256 checksum file](https://dev-docs.nebula-graph.io/downloads/exchange/5.3.0/nebula-graph-exchange-5.3.0.tgz.sha256sum.txt) and follow [Verify a package](https://dev-docs.nebula-graph.io/v5.3.2/utilities/#verify-download).

## Steps

1. 

Extract the package in the download directory:

````
tar -xzf nebula-graph-exchange-5.3.0.tgz

````

The extracted directory contains these files:

````
nebula-graph-exchange/
├── deploy.sh  # The script for deploying NebulaGraph Exchange and required dependencies
├── start.sh  # The script for starting NebulaGraph Exchange
├── stop.sh  # The script for stopping NebulaGraph Exchange
├── import.sh  # The script for importing data
├── export.sh  # The script for exporting data
├── monitor.sh  # The script for monitoring the import or export process
├── nebula-exchange-5.3.0.jar # The NebulaGraph Exchange JAR package
├── cli-5.3.0.jar # The JAR package of the CLI tool
├── scala-2.12.11.tgz  # The Scala package
├── spark-2.4.7-bin-hadoop2.7.tar.gz  # The Spark package
├── jdk-8u431-linux-x64.tar.gz # The JDK package for x64 architecture
├── jdk-8u431-linux-aarch64.tar.gz # The JDK package for ARM architecture
├── README.md  # The README file
└── template/  # The configuration templates for different data sources

````

2. 

Enter the extracted directory and deploy Spark with `cli-5.3.0.jar`. Replace the example IP `192.168.8.113` with the IP address of the Linux machine:

````
cd nebula-graph-exchange
java -jar cli-5.3.0.jar -deploy -i 5 -c 2 -ip 192.168.8.113 -port 1077 -webPort 1088

````

The following table lists the command-line options:

 | Option | Alias | Description | Required | Default value
 | `-deploy` | - | Whether to deploy the Spark server. | No | N/A
 | `-instance` | `-i` | The number of worker instances on each machine. | No | `5`
 | `-cores` | `-c` | The number of cores for each worker instance. | No | `60`
 | `-ip` | - | The local IP of the Spark server. If not specified, the IP is automatically obtained. | No | N/A
 | `-port` | - | The port of the Spark server. | No | `1077`
 | `-webPort` | - | The port of the web UI for the Spark server. | No | `1088`
 | `-h` | - | Whether to print help information. | No | N/A

The following message is displayed if the setup is successful:

````
Setup completed successfully!
