sudo wget https://downloads.apache.org/guacamole/1.5.4/source/guacamole-server-1.5.4.tar.gz

Then, extract your download package and navigate to the Apache Guacamole directory with the following commands:

sudo tar -xvf guacamole-server-1.5.4.tar.gz

sudo cd guacamole-server-1.5.4

Now you can build and install Apache Guacamole on Ubuntu 22.04. To do this, you can run the following commands:

sudo ./configure --with-init-dir=/etc/init.d --enable-allow-freerdp-snapshots
sudo make
sudo make install

The build and installation process may take some time to complete. Once you are done, update the installed library cache with the command below:

sudo ldconfig

Start and Enable Apache Guacamole Server on Ubuntu 22.04

At this point, you have learned to build and install Apache Guacamole on Ubuntu 22.04. Now you must reload the systemd to apply the changes:

sudo systemctl daemon-reload

Then, start and enable the Guacamole server with the following commands:

sudo systemctl start guacd
sudo systemctl enable guacd

Also, you can verify Guacamole server is active and running on Ubuntu 22.04 with the following command:

sudo systemctl status guacd

In your output, you should see:

Guacd Service - Install Apache Guacamole on Ubuntu 22.04
Install Apache Guacamole on Ubuntu 22.04

Note: You should create the Guacamole configuration files and extensions. These files will used in the later steps. To do this, you can run:

sudo mkdir -p /etc/guacamole/{extensions,lib}

Step 3 – Install the Guacamole Web App on Ubuntu 22.04

At this point, you must install the Guacamole Web App on your Ubuntu 22.04. It is the frontend interface of Apache Guacamole. To do this, you must install the Tomcat 9 by using the command below:

sudo apt install tomcat9 tomcat9-admin tomcat9-common tomcat9-user -y

Then, download the Guacamole Web App client by using the following command: You should note that download the version with the Guacamole version you have installed.

sudo wget https://downloads.apache.org/guacamole/1.5.4/binary/guacamole-1.5.4.war

Now you must move the Guacamole Web client to the Tomcat web directory. To do this, run the command below:

sudo mv guacamole-1.5.4.war /var/lib/tomcat9/webapps/guacamole.war

To apply the changes, restart Apache Guacamole and Tomcat services:

sudo systemctl restart tomcat9 guacd

Step 4 – Configure Apache Guacamole Database Authentication

At this point, you have learned to install Apache Guacamole on Ubuntu 22.04 and set up the client Web app. As you may know, Guacamole supports basic user authentication that is used for testing. In this guide, we want to use production-ready database authentication through MariaDB.

First, install MariaDB on Ubuntu 22.04 with the command below:

sudo apt install mariadb-server -y

Then, run the following command to secure your MariaDB installation and set up a password for it.

sudo mysql_secure_installation

Once you are done, you need to install the MySQL Connector/J library and Guacamole JDBC authenticator plugin. To do this, you can download the Java connector with the command below:

sudo wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-8.0.26.tar.gz

Then, you must extract the downloaded file and copy it to the /etc/guacamole/lib/ directory:

sudo tar -xf mysql-connector-java-8.0.26.tar.gz

sudo cp mysql-connector-java-8.0.26/mysql-connector-java-8.0.26.jar /etc/guacamole/lib/

Next, you must download the Apache Guacamole JDBC AUTH Plugin. To do this, you can run the command below:

sudo wget https://downloads.apache.org/guacamole/1.5.4/binary/guacamole-auth-jdbc-1.5.4.tar.gz

You should note that download the version with the Guacamole version you have installed.

Now extract the downloaded file and copy it to /etc/guacamole/extensions/ directory:

sudo tar -xf guacamole-auth-jdbc-1.5.4.tar.gz

sudo mv guacamole-auth-jdbc-1.5.4/mysql/guacamole-auth-jdbc-mysql-1.5.4.jar /etc/guacamole/extensions/

Create a Guacamole Database and User

At this point, you must log in to your MariaDB shell and create a user and database for Apache Guacamole on Ubuntu 22.04.

First, log in to the MariaDB shell with the password you have configured it for:

sudo mysql -u root -p

From your MariaDB shell, run the commands below to create the user and database, and grant the privileges:

MariaDB [(none)]> CREATE DATABASE guac_db;
MariaDB [(none)]> CREATE USER 'guac_user'@'localhost' IDENTIFIED BY 'password';
MariaDB [(none)]> GRANT SELECT,INSERT,UPDATE,DELETE ON guac_db.* TO 'guac_user'@'localhost';
MariaDB [(none)]> FLUSH PRIVILEGES;

Once you are done, exit from your MariaDB shell:

MariaDB [(none)]> EXIT;

Import SQL Schema Files and Create Properties Files For Guacamole

At this point, you must navigate to the MySQL Schema directory with the command below:

cd guacamole-auth-jdbc-1.5.4/mysql/schema

From there, run the command below to import the SQL schema files to the MySQL database:

cat *.sql | mysql -u root -p guac_db

Then, use your favorite text editor like Vi editor or Nano editor to create the properties file for Apache Guacamole:

sudo vi /etc/guacamole/guacamole.properties

Add the following configuration settings to the file with your database credentials:

# MySQL properties
mysql-hostname: 127.0.0.1
mysql-port: 3306
mysql-database: guac_db
mysql-username: guac_user
mysql-password: password

Once you are done, save and close the file.

Finally, restart the services to apply the changes:

sudo systemctl restart tomcat9 guacd mysql

Step 5 – Access Apache Guacamole From the Web Interface
