Apache Guacamole is a clientless remote desktop gateway that allows users to access their desktops from anywhere using a web browser. It supports standard protocols like VNC, RDP, and SSH. In this guide, we will walk through the steps to install and use Apache Guacamole on Rocky Linux 8.

Step 1: Update Your System

Start by ensuring your system is up to date:

sudo dnf update

Step 2: Install Required Dependencies

Install the necessary dependencies for Guacamole:

sudo dnf install -y gcc gcc-c++ tomcat postgresql postgresql-server postgresql-devel

Step 3: Install Guacamole Server

Download the latest version of Apache Guacamole server:

wget https://apache.org/dyn/closer.cgi?action=download&filename=guacamole/1.5.0/source/guacamole-server-1.5.0.tar.gz

Extract the downloaded file:

tar -xzf guacamole-server-1.5.0.tar.gz

Navigate to the extracted directory:

cd guacamole-server-1.5.0

Compile and install Guacamole:

./configure --with-postgresql
make
sudo make install

Step 4: Install Guacamole Client

Download the latest version of the Guacamole client:

wget https://apache.org/dyn/closer.cgi?action=download&filename=guacamole/1.5.0/binary/guacamole-1.5.0.war

Move the client to the Tomcat webapps directory:

sudo mv guacamole-1.5.0.war /var/lib/tomcat/webapps/guacamole.war

Step 5: Configure Guacamole Properties

Create the Guacamole configuration directory:

sudo mkdir /etc/guacamole

Next, create the Guacamole properties file:

sudo nano /etc/guacamole/guacamole.properties

Add the following lines to configure the database connection:

guacd-hostname=localhost
guacd-port=4822
# Use the PostgreSQL database
db-driver=postgresql
db-hostname=localhost
db-port=5432
db-username=guacadmin
db-password=your_password

Replace your_password with the actual password for your database user.

Step 6: Set Up Database

Initialize the PostgreSQL database:

sudo postgresql-setup initdb

Start and enable the PostgreSQL service:

sudo systemctl start postgresql
sudo systemctl enable postgresql

Log into PostgreSQL:

sudo -u postgres psql

Run the following commands to create the necessary database and user:

CREATE DATABASE guacamole;
CREATE USER guacadmin WITH PASSWORD 'your_password';
GRANT ALL PRIVILEGES ON DATABASE guacamole TO guacadmin;
\q

Step 7: Start Tomcat and Guacamole

Start and enable Tomcat:

sudo systemctl start tomcat
sudo systemctl enable tomcat

Start the Guacamole daemon:

sudo systemctl start guacd
sudo systemctl enable guacd

Step 8: Access Guacamole Web Interface

You can now access the Guacamole web interface by navigating to:

http://your_domain_or_ip:8080/guacamole

Log in using the username guacadmin and the password you set earlier.
