Deploy Studio

This topic describes how to deploy Studio locally by Docker, RPM, and tar package.

Note

You can also try some functions online in Studio.

RPM-based Studio

Prerequisites

Before you deploy RPM-based Studio, you must confirm that:

  • If your Linux distribution is CentOS, install lsof and Node.js of versions above v10.16.0+.

    Note

    node and npm should be installed in /usr/bin/ directory. Avoid the situation that the node command cannot be found during RPM installation. For example, the default directory of nodejs12 is in /opt/rh/rh-nodejs12, you can use following commands to build soft link:

    $ sudo ln -s /opt/rh/rh-nodejs12/root/usr/bin/node /usr/bin/node
    $ sudo ln -s /opt/rh/rh-nodejs12/root/usr/bin/npm /usr/bin/npm
    
  • Before the installation starts, the following ports are not occupied.

    Port Description
    7001 Web service provided by Studio.
    8080 HTTP service provided by Nebula HTTP Gateway.

Install

  1. Select and download the RPM package according to your needs. It is recommended to select the latest version. Common links are as follows:

    Installation package Checksum Nebula version
    nebula-graph-studio-3.1.0-1.x86_64.rpm nebula-graph-studio-3.1.0-1.x86_64.rpm.sha256 v2.6.1
  2. Use sudo rpm -i <rpm> to install RPM package.

    For example, install Studio 3.1.0, use the following command:

    sudo rpm -i nebula-graph-studio-3.1.0-1.x86_64.rpm
    

    When the screen returns the following message, it means that the PRM-based Studio has been successfully started.

    egg started on http://0.0.0.0:7001
    nohup: Add the output to "nohup.out"
    
  3. When Docker-based Studio is started, use http://ip address:7001 to get access to Studio.

    Note

    Run ifconfig or ipconfig to get the IP address of the machine where Docker-based Studio is running. On the machine running Docker-based Studio, you can use http://localhost:7001 to get access to Studio.

    If you can see the Config Server page on the browser, Docker-based Studio is started successfully.

    The Config Server page shows that Docker-based Studio is started successfully

Uninstall

Users can uninstall Studio using the following command:

sudo rpm -e nebula-graph-studio-3.1.0-1.x86_64

Exception handling

If the automatic start fails during the installation process or you want to manually start or stop the service, use the following command:

  • Start the service manually
    bash /usr/local/nebula-graph-studio/scripts/rpm/start.sh
    
  • Stop the service manually
    bash /usr/local/nebula-graph-studio/scripts/rpm/stop.sh
    

If you encounter an error bind EADDRINUSE 0.0.0.0:7001 when starting the service, you can use the following command to check port 7001 usage.

lsof -i:7001

If the port is occupied and the process on that port cannot be terminated, you can use the following command to change Studio service port and restart the service.

 //Open the configuration file
 $ vi config/config.default.js

 //Change the port number
 ...
     config.cluster = {
         listen: {
             port: 7001, // Modify this port number and change it to any one currently available
             hostname: '0.0.0.0',
         },
     };
 ...

 //Restart npm
 $ npm run start

tar-based Studio

Prerequisites

Before you deploy tar-based Studio , you must do a check of these:

  • The Linux distribution is CentOS, installed lsof and Node.js of version above v10.16.0+.

    Note

    node and npm should be installed in /usr/bin/ directory. Avoid the situation that the node command cannot be found during RPM installation. For example, the default directory of nodejs12 is in /opt/rh/rh-nodejs12, you can use following commands to build soft link:

    $ sudo ln -s /opt/rh/rh-nodejs12/root/usr/bin/node /usr/bin/node
    $ sudo ln -s /opt/rh/rh-nodejs12/root/usr/bin/npm /usr/bin/npm
    
  • Before the installation starts, the following ports are not occupied.

    Port Description
    7001 Web service provided by Studio
    8080 Nebula-http-gateway, Client's HTTP service

Install

  1. Select and download the tar package according to your needs. It is recommended to select the latest version. Common links are as follows:

    Installation package Studio version
    nebula-graph-studio-3.1.0-1.x86_64.tar.gz 3.1.0
  2. Use tar -xvf to decompress the tar package.

    tar -xvf nebula-graph-studio-3.1.0-1.x86_64.tar.gz
    

Procedure

Note

The root directory nebula-graph-studio has two installation packages: nebula-graph-studio and nebula-importer. You need to deploy and start the services separately on the same machine to complete the deployment of Studio.

  1. Deploy and start nebula-http-gateway.

    $ cd nebula-http-gateway
    $ nohup ./nebula-httpd &
    
  2. Deploy and start nebula-graph-studio.

    $ cd nebula-graph-studio
    $ npm run start
    

    Caution

    Studio 2.6.1 version is not dependent on nebula-importer, so the installation and deployment procedure is different from Studio v3.0.0.

  3. When tar-based Studio is started, use http://ip address:7001 to get access to Studio.

    Note

    Run ifconfig or ipconfig to get the IP address of the machine where Docker-based Studio is running. On the machine running Docker-based Studio, you can use http://localhost:7001 to get access to Studio.

    If you can see the Config Server page on the browser, Docker-based Studio is started successfully.

    The Config Server page shows that Docker-based Studio is started successfully

Stop Service

You can use kill pid to stop the service:

$ kill $(lsof -t -i :8080) # stop nebula-http-gateway
$ cd nebula-graph-studio
$ npm run stop # stop nebula-graph-studio

Docker-based Studio

Prerequisites

Before you deploy Docker-based Studio, you must do a check of these:

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

    Port Description
    7001 Web service provided by Studio
    8080 Nebula-http-gateway, Client's HTTP service

Procedure

To deploy and start Docker-based Studio, run the following commands. Here we use Nebula Graph v2.6.1 for demonstration:

  1. Download the configuration files for the deployment.

    Installation package Nebula Graph version
    nebula-graph-studio-v3.tar.gz v2.6.1
  2. Create the nebula-graph-studio-v3 directory and decompress the installation package to the directory.

    mkdir nebula-graph-studio-v3 && tar -zxvf nebula-graph-studio-v3.gz -C nebula-graph-studio-v3
    
  3. Change to the nebula-graph-studio-v3 directory.

    cd nebula-graph-studio-v3
    

  4. Pull the Docker image of Studio.

    docker-compose pull
    
  5. Build and start Docker-based Studio. In this command, -d is to run the containers in the background.

    docker-compose up -d
    

    If these lines are returned, Docker-based Studio v3.x is deployed and started.

    Creating docker_client_1   ... done
    Creating docker_web_1      ... done
    Creating docker_nginx_1    ... done
    
  6. When Docker-based Studio is started, use http://ip address:7001 to get access to Studio.

    Note

    Run ifconfig or ipconfig to get the IP address of the machine where Docker-based Studio is running. On the machine running Docker-based Studio, you can use http://localhost:7001 to get access to Studio.

    If you can see the Config Server page on the browser, Docker-based Studio is started successfully.

    The Config Server page shows that Docker-based Studio is started successfully

Next to do

On the Config Server page, connect Docker-based Studio to Nebula Graph. For more information, see Connect to Nebula Graph.
