Apache Guacamole – Access Your Computer From Anywhere Via Web Browser
Apache Guacamole is a clientless HTML5 web application that can be used to access your remote servers and desktops via a web browser. All you need is just a web browser, No additional softwares, plugins required. Install Guacamole on any system and start accessing your remote desktops in no time. It is completely free and open source software.
Access Your Computer From Anywhere Via Web Browser using Apache Guacamole
You can install it using the official way which is bit complicated for newbies and intermediate users. Alternatively, there is a script called “Guacamole Install Script” to do this automatically. This script will install latest Apache Guacamole version on your Linux system. Only little user intervention is required. Everything will be performed automatically. It will install all necessary dependencies and packages that needed to setup a perfect remote desktop gateway. This script will work on a clean CentOS 6.x and 7.x versions. Here is the list of things It will do:
- Install Packages Dependencies
- Download Guacamole and MySQL Connector packages
- Install Guacamole Server
- Install Guacamole Client
- Install MySQL Connector
- Configure MariaDB or MySQL
- Setting Tomcat Server
- Generates a Java KeyStore for SSL Support
- Install and Setting Nginx Proxy (SPDY enabled)
- Generates a Self-Signed Certificate for SSL Support
- Configure SELinux for Nginx Proxy
- Configure FirewallD or iptables
Now, let us see how to install Guacamole in CentOS 7 64 bit minimal edition.
Download the Guacamole installer script from this link.
Or run the following command from your Terminal to download it.
Make the script executable using command:
chmod +x guacamole-install-script.sh
Then, run it to install Guacamole on your CentOS system.
You will be asked to answer a few questions such as root password for MariaDB, Guacamole database name, database user, database user’s password, and Guacamole URL etc. Answer them accordingly. I use “centos” as password in this tutorial for the sake of easy remembrance. But I recommend to use any strong password.

Now, the installer script will start to download all necessary software to setup the remote desktop gateway. This will take a while depending upon the Internet speed.
After a few minutes, you will asked to complete the wizard for Java KeyStore. Answer them accordingly and type Yes to continue.

Finally, you will see the end of installation message. Note down the Guacamole management URL. You will need it to log in to the management console to access the remote systems.
Finished Successfully You can check the log file /root/guacamole-0.9.9.10-17-Jan.log Your firewall backup file /root/guacamole-0.9.9.10-17-Jan.firewall.bkp To manage the Guacamole GW via proxy go to http://<IP>/guacamole/ or https://<IP>/guacamole/ To manage the Guacamole GW go to http://<IP>:8080/guacamole/ or https://<IP>:8443/guacamole/ The username and password is: guacadmin If you have any suggestions please write to: firstname.lastname@example.org
Access Guacamole Dashboard
Open up your web browser and type http://<IP>:8080/guacamole/ or https://<IP>:8080/guacamole/ in the address bar. You will see the following welcome screen. Enter the username and password to access the Guacamole web interface. The default username and password is: guacadmin
Here it is how Guacamole dashboard looks like.
As you see, we haven’t created any remote desktop connections yet. The first thing you must do is to change the default user guacadmin’s password. To do so, go to Settings page of guacadmin.
Go to the Preferences link. Enter your current password and update the new password.
Make new Connections
Now, let us create new remote desktop connection. To do so, go to guacadmin -> Settings -> Connections. And then, Click New Connection.
Enter your remote system details such as name, IP address or hostname, port number, username and password of the remote system details. Also, you need to select the type of protocol from the Protocol drop-down menu.
Similarly, you can create other connections by selecting different protocols such as RDP, VNC and telnet etc. Once you created the new connection, you can launch it from the guacadmin drop-down menu at the top right corner.
Here is my Ubuntu 16.04 system’s active SSH session in browser.
Once you done with your remote system, you can disconnect from it from Guacamole menu.
The Guacamole menu is a sidebar which is hidden until explicitly shown. To bring up this menu, you need to press CTRL+ALT+SHIFT key combination on a desktop. To close/hide this menu, press CTRL+ALT+SHIFT again. On mobiles devices, you can bring up this menu by swiping right from the left edge of the screen. To hide the menu, swipe left across the screen.
Like I said, this script will only work on CentOS 6/7 systems. We will post the installation instructions for other Linux distributions in the days to come. Until then, please refer the official installation document to setup Guacamole in other Linux distributions like Ubuntu, SUSE, Debian etc.
This script made Guacamole installation much easier than the official method. If you wanted to setup a remote desktop gateway in CentOS, you can use this script. I hope the author will make a common installer script to all Linux systems.
