Getting started with remote developmentProfessional

Launch JetBrains Gateway and connect to a remote server

1. Download and install the JetBrains Gateway launcher.

   Alternatively, you can access JetBrains Gateway from the welcome screen of your IDE through the Remote Development option.

2. In the Remote Development wizard, click Connect via SSH.

   

   note

   You can also click Connect to Remote Host with a Link and enter a link that you previously generated to connect either to a Code With Me session or to a remote server.

3. On the next page of the wizard, specify the SSH configuration through which you want to connect to a remote server.

   

   Alternatively, click to open the SSH Configurations dialog and configure the SSH settings.

   In the SSH Configurations dialog, add the following information:

   

   • Host: specify the address of your remote server.

   • Port: specify the SSH port, which defaults to 22.

   • Local port: specify the outgoing port.

     For example, TCP 10.101.0.1:50705->13.49.137.87:22 (ESTABLISHED).

   • User name: specify the name of a user on a remote server.

   • Authentication type: select one of the following authentication methods:

     • Password: to access the host with a password. To save the password in PyCharm, select the Save password checkbox.

     • Key pair (OpenSSH or PuTTY): to use SSH authentication with a key pair. To apply this authentication method, you must have a private key on the client machine and a public key on the remote server. PyCharm supports private keys that are generated with the OpenSSH utility.

       Specify the path to the file where your private key is stored and type the passphrase (if any) in the corresponding fields. To have PyCharm remember the passphrase, select the Save passphrase checkbox.

     • Parse config file ~/.ssh/config: select this option if you want JetBrains Gateway to use the .ssh/config file.

   • Test Connection: click this button to see whether the connection is established.

   • Connection Parameters: use this section to configure additional parameters for the connection.

   • HTTP/SOCKS Proxy: use this section to configure proxy settings. For more information, refer to Proxy settings.

   Click OK to save the changes and return to the Welcome to JetBrains Gateway dialog.

   Click Check Connection and Continue to check whether the connection is established.

4. On the next page, specify the PyCharm version to download to the remote server. JetBrains Gateway displays a list of the IDEs versions that are available for downloading and the already installed ones. The versions on JetBrains Client and the remote host must be the same.

   note

   By default, the downloaded PyCharm is located in the following folder on the remote server: ~/.cache/JetBrains/RemoteDev/dist.

   

   Add the path to your project on the remote host.

   

   Click Download and Start IDE.

   JetBrains Gateway downloads the IDE, and opens your remote project in JetBrains Client. The connection is shown in the JetBrains Gateway window, from which you can connect to other IDEs or disable the connection. This window is hidden to tray by default.

   

Open recent projects

1. In the JetBrains Gateway wizard, select SSH from the options on the left.

2. In the search field enter the name of your project to quickly navigate to it.

   

   If you need to quickly access the terminal, click .

Stop the running instance

1. In the JetBrains Gateway wizard, select SSH from the options on the left.

2. When your remote session is active, the Running indicator is displayed against the project.

   Click against the project and select Stop Instance to stop the remote session for the project in question.

   

   You can also select Remove from Recent Projects to remove the project listed on the page altogether.

Connect from the local IDE

1. Make sure you have downloaded and installed JetBrains Gateway on your local machine.

2. Make sure you have an SSH connection and the PyCharm IDE on the remote host.

3. In the terminal, run the following command:

   remote-dev-server.sh run <path/to/project> --ssh-link-host <host>

   For example, ~/PY-213.5744.248/bin/remote-dev-server.sh run ~/home/jetbrains/PythonProjects/SampleApp/ --ssh-link-host ec2-13-50-136-85.eu-north-1.compute.amazonaws.com

   note

   You can specify other SSH options. For more information, run the following command:

   remote-dev-server.sh --help

   The remote-dev-server.sh script, along with the downloaded IDE and the IDE logs are located in the bin directory on the remote server. To locate it, you can run the following command:

   which will output the path to the remote-dev-server.sh script:

   /home/ubuntu/.cache/JetBrains/RemoteDev/dist/247c8fb97bb32_PyCharm-213.5744.248/bin/remote-dev-server.sh

4. As an output, you should receive the following link:

   Http link: https://code-with-me...

5. Copy the generated link and paste it into your local browser.

6. In the dialog that opens, click Open JetBrains Gateway.

   

   The JetBrains Gateway welcome screen opens.

7. In the Connect to Remote Host with a Link section, enter the same generated link to start a remote session.

8. Click Connect. PyCharm opens the remote project in JetBrains Client.

Connect via Space

1. Launch JetBrains Gateway.

2. On the JetBrains Gateway starting page, select JetBrains Space and click Connect to Space.

3. Log in to JetBrains Space with your credentials.

   

4. Click Continue in Browser and make sure you are connected.

   

   Click Allow to get back to JetBrains Gateway.

5. In JetBrains Gateway, click Browse Dev Environments.

   

6. In Space, configure the dev environment you want to use.

7. Find the project you want to open remotely and click Open in IDE.

8. In the dialog that opens, in the Select IDE drop-down, select PyCharm with Gateway, configure other options if you need, and click Create.

9. On the page that opens, click Open JetBrains Gateway.

   

   JetBrains Gateway launches, downloads all the necessary backend components, and opens JetBrains Client with your project where you can work further.

Install a plugin via the command line

If you manually configure PyCharm on the remote server, use the following steps to add plugins:

1. From the JetBrains Marketplace page, find a page of the required plugin, select "Versions" tab, click any version to copy pluginId (short name such as org.rust.lang) of the plugin you want to install.

2. Open of the remote server and add the following command:

   bin/remote-dev-server.sh installPlugins PROJECT_PATH pluginId

   (where PROJECT_PATH is a path to your remote project and pluginId is an ID you got from the JetBrains Marketplace page.)

3. Continue with launching JetBrains Gateway and opening the remote project with the remotely installed plugin.

Install a plugin via UI

If you use JetBrains Gateway to download PyCharm to a remote server, use the following steps to install plugins.

1. Open a remote project in JetBrains Client.

2. Press Ctrl+Alt+S to open the IDE settings and select Plugins On Host.

3. Download the needed plugin the same way as you would in a regular PyCharm project.

   

   For more information on regular plugin installation, refer to Install plugins.

4. After you download and enable the plugin, click OK to save the changes.

   The plugin is installed remotely. However, keep in mind that the plugin is installed per project.

Add an SDK to the opened project

When you first open a project, PyCharm displays a notification suggesting to add the project SDK.

1. Open the remote session.

2. From the main menu, select File | Project Structure.

3. In the Project Structure dialog, select Project, and from the available options, configure the project's SDK.

4. Click OK to save the changes. PyCharm downloads the configured SDK to the remote server. The next time you open your project, the downloaded SDK will be used automatically in the remote session.

Add VM options

You can adjust VM options for the remote project, especially if you want to increase the -Xmx memory size when working with a larger project. You need to perform those actions and save your changes on the remote server.

1. In the command line, run the following command:

   $IDE_BIN_DIR/${IDE_PRODUCT_VM_OPTIONS}.vmoptions

   Check the following example:

   ./.cache/JetBrains/RemoteDev/dist/a17ad99f7faf8_ideaIU-2021.3.1/bin/idea64.vmoptions

2. Edit the pycharm64.vmoptions file.

   For example, change the -Xmx2048 option to -Xmx3072.

   For more detailed information on VM options, refer to Advanced configuration.

3. Save the changes and restart your IDE on the remote server. Your changes will appear in your remote project.

Access the backend IDE UI

If you encounter a problem working in JetBrains Client, you can open a main tool window of the backend IDE and try to fix your problem there.

1. On the main toolbar, click next to IDE Backend.

2. Select Open main tool window.

   

   The main window of the backend IDE gets projected. Now you can use it to access remote settings and configure various remote options if you couldn't do that in JetBrains Client.

   note

   Keep in mind that the remote server is Linux, so the shortcuts that you use to configure remote settings must be the Linux ones.

Close the Remote Development session

• Click to close the remote session window.

  You are returned to the JetBrains Gateway welcome screen where you can use the Recent SSH projects page to reconnect to your remote session or stop the running instance.

  note

  When you close the project locally, it doesn't get automatically closed on the remote host.

Create multiple connections

You can create multiple connections to the same remote host and the same version of the IDE. You can also have connections with different IDE versions and remote hosts.

1. Connect and open a remote session.

2. Since JetBrains Gateway is constantly active once you have connected to the remote server, you can click its icon to open the JetBrains Gateway welcome screen and configure other connections.

   If you connect to the same IDE version, then JetBrains Client will be opened as an instance of the same process. If you connect to a different remote host or IDE version, a different remote session will be launched.

   note

   You cannot connect to the same server from different computers. For example, if you share a remote server with your team and want to work on the same project, either wait until the server is free or request the Code With Me link from the connected party to join the remote session.
