8 Easy Steps to Install Guacamole on Ubuntu

If you’re looking to Install Guacamole on your Ubuntu system, you’re in for a treat! Guacamole is an open-source and user-friendly remote desktop gateway that can make your remote work and administration tasks smoother than ever. So, grab your favorite chips (or in this case, your Ubuntu machine), and let’s get started with this delicious adventure!

What is Guacamole, Anyway?

Guacamole is not just a tasty dip; it’s a software that allows you to access your computer remotely through a web browser. Whether you’re miles away from your workstation or just want to manage a server without being physically present, Guacamole makes it possible. It’s like having your own digital avocado that you can slice and serve from anywhere.

Features of Guacamole

Guacamole is not typically used to manage Remote Desktop Protocol (RDP) connections directly, as it’s primarily a web-based remote desktop gateway and protocol agnostic. However, you can use Guacamole in combination with RDP to provide remote desktop access through a web browser. Here’s how you can set it up:

1. Install Guacamole
   Set up and install the Guacamole web application on a server. You can find installation instructions for your specific operating system and distribution on the official Guacamole website.
2. Configure Guacamole
   After installation, configure Guacamole to connect to your RDP-enabled machines. This involves defining connection parameters such as the RDP server’s IP address or hostname, port, and authentication details.
3. User Authentication
   Guacamole can integrate with various authentication mechanisms, such as LDAP, database authentication, or even SAML-based Single Sign-On (SSO), depending on your organization’s needs.
4. Access via Web Browser
   Users can access remote desktops via a web browser by logging into the Guacamole web interface. Once logged in, they can select the RDP connection configured earlier and initiate an RDP session.
5. Secure Access
   Ensure that the Guacamole server is securely configured and protected. It’s essential to use encryption (HTTPS) for the web interface, implement strong access controls, and regularly update both the Guacamole software and the underlying server to address security vulnerabilities.
6. Logging and Monitoring
   Guacamole can provide logging and monitoring capabilities, which can help you keep track of user activities, troubleshoot issues, and maintain the security of your RDP connections.

By setting up Guacamole in this way, you can centralize RDP access management and provide a web-based interface for users to access remote Windows machines securely. It’s important to follow best practices for security when implementing such solutions, especially when dealing with remote access to sensitive systems.

How to Install Guacamole?

Step 1: Update Your System

Before any installation, it’s always a good idea to ensure your system is up-to-date. Open a terminal (Ctrl + Alt + T) and run the following commands:

sudo apt update
sudo apt upgrade -y

This will update your package lists and upgrade your system packages.

Step 2: Install Required Packages

Next, we need to install a few packages that Guacamole relies on. These include Tomcat, MySQL, and some other utilities. Execute the following command:

sudo apt install -y tomcat9 tomcat9-admin tomcat9-common tomcat9-user mysql-server mysql-client mysql-common mysql-utilities

During the installation, you will be prompted to set a root password for MySQL. Make sure to choose a strong password and remember it.

Step 3: Configure MySQL

Now, it’s time to configure MySQL. Run the following command and follow the prompts to secure your MySQL installation:

sudo mysql_secure_installation

Step 4: Create Guacamole Database and User

We need to create a database and user for Guacamole in MySQL. Run the following commands to do so:

sudo mysql -u root -p

Enter your MySQL root password when prompted. Then, execute the following SQL commands:

CREATE DATABASE guacamole_db;
CREATE USER 'guacamole_user'@'localhost' IDENTIFIED BY 'your_password_here';
GRANT SELECT,INSERT,UPDATE,DELETE ON guacamole_db.* TO 'guacamole_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Replace 'your_password_here' with a strong password for the Guacamole user.

Step 5: Download and Install Guacamole

Now, let’s download and install Guacamole and its extensions. Execute the following commands:

sudo apt install -y guacamole guacamole-tomcat guacamole-mysql

During the installation, you’ll be asked to configure the Guacamole MySQL extension. Provide the following information:

• Hostname: localhost
• Port: 3306
• Database: guacamole_db
• Username: guacamole_user
• Password: (Enter the password you set for the Guacamole user in Step 4)

Step 6: Configure Guacamole

It’s time to configure Guacamole. First, create a symbolic link for the Guacamole configuration file:

sudo ln -s /etc/guacamole/guacamole.properties /usr/share/tomcat9/.guacamole/guacamole.properties

Next, configure Guacamole’s authentication using the following command:

sudo nano /etc/guacamole/guacamole.properties

Inside the file, find the lines that start with guacd-hostname: and guacd-port:. Uncomment and modify them as follows:

guacd-hostname: localhost
guacd-port: 4822

Save the file and exit.

Step 7: Start and Enable Tomcat

Now, start Tomcat and enable it to run at startup:

sudo systemctl start tomcat9
sudo systemctl enable tomcat9

Step 8: Access Guacamole Web Interface

Open your web browser and enter the following URL:

http://your_server_ip_or_domain/guacamole

Replace your_server_ip_or_domain with your server’s IP address or domain name. You should see the Guacamole login page. The default username and password are both guacadmin. Be sure to change these credentials after your first login.
