Apache Guacamole is an open source HTML5-based web application used as a remote desktop gateway. With the Guacamole Marketplace App, you can access your Linode with a graphical VNC session using the XFCE desktop environment from any device. This Marketplace App installs and configures Guacamole on a Linode, complete with an SSL certificate generated by Certbot for your domain.
Deploying the Guacamole Marketplace App
The Linode Marketplace allows you to easily deploy software on a Linode using the Linode Cloud Manager.
Log in to the Cloud Manager and select the Marketplace link from the left navigation menu. This displays the Linode Compute Create page with the Marketplace tab pre-selected.
Under the Select App section, select the app you would like to deploy.
Fill out all required Options for the selected app as well as any desired Advanced Options (which are optional). See the Configuration Options section for details.
Complete the rest of the form as discussed within the Getting Started > Create a Linode.
Click the Create Linode button. Once the Linode has provisioned and has fully powered on, wait for the software installation to complete. If the Linode is powered off or restarted before this time, the software installation will likely fail. To determine if the installation has completed, open the Linode’s Lish console and wait for the system login prompt to appear.
Follow the instructions within the Getting Started After Deployment section.
Software installation should complete within 5-20 minutes after the Linode has finished provisioning.
Configuration Options
Guacamole Options
You can configure your Guacamole App by providing values for the following fields:
| Field | Description |
|---|---|
| The limited sudo/VNC user to be created for the Linode | The VNC username created for this Linode with sudo permissions. This is used for your VNC session. Required. |
| The password for the limited sudo/VNC user | Password for your sudo/VNC user. This is used for your VNC session. Required. |
| The username to be used with Guacamole | Your Guacamole Username. This is used to log in to Guacamole. Required. |
| The password to be used with Guacamole | Your Guacamole Password. This is used to log in to Guacamole. Required |
| Your Linode API Token | Your Linode API Token is needed to create DNS records. If this is provided along with the Subdomain and Domain fields, the installation attempts to create DNS records via the Linode API. If you don’t have a token, but you want the installation to create DNS records, you must
create a token to use in this field before continuing. |
| Subdomain | The subdomain you wish the installer to create a DNS record for during setup. The suggestion given is www. The subdomain can only be created if you also provide a Domain and API Token. |
| Domain | The domain name where you wish to host your Guacamole server. The installer creates a DNS record for this domain during setup if you provide this field along with the required API Token. |
| Admin Email | The email address to register with
Certbot when generating an SSL certificate for your absolute domain. This field is required along with your API Token and Domain for HTTPS access to your Guacamole remote desktop. |
General Options
For advice on filling out the remaining options on the Create a Linode form, see Getting Started > Create a Linode. That said, some options may be limited or recommended based on this Marketplace App:
- Supported distributions: Debian 10
- Recommended plan: All plan types and sizes can be used with Guacamole.
Getting Started after Deployment
Access your Guacamole App
After Guacamole has finished installing, access the dashboard over http:// or https:// with your Linode’s IPv4 address or absolute domain name, depending on your setup choices.
If you set up a domain name for your Guacamole App during setup, skip to step 3.
If you didn’t set up a domain name, find your Linode’s IPv4 address by clicking on Linodes in the Cloud Manager sidebar to see a list of all your Linodes. Find the Linode you just created. Under the IP Address column, copy the IPv4 address.
Enter your Linode’s absolute domain or IPv4 address into a browser window (for example,
http://192.0.2.0) to access the Guacamole login page. Enter your Guacamole username and password.
Note
The Guacamole login page may take several minutes to become available while the Application completes the creation process.Once you’ve completed the login process, you have full access to your Linode from your Guacamole remote desktop using VNC and the XFCE desktop environment.
Additional tasks can be performed remotely through your web browser. For example, you can install the Firefox web browser for use with your Guacamole remote desktop by entering the following command in its Terminal Emulator:
sudo apt install firefox-esrWhen prompted, enter the password you chose for the limited sudo/VNC user. You can now browse the web on your Guacamole browser from within your local browser.
NoteCurrently, Linode does not manage software and systems updates for Marketplace Apps. It is up to the user to perform routine maintenance on software deployed in this fashion.
