What is Guacamole?
Guacamole is an HTML5 remote desktop gateway.
Guacamole provides access to desktop environments using remote desktop protocols like VNC and RDP. A centralized server acts as a tunnel and proxy, allowing access to multiple desktops through a web browser.
No browser plugins are needed, and no client software needs to be installed. The client requires nothing more than a web browser supporting HTML5 and AJAX.
Installing Guacamole on Amahi
Dependencies
The following dependencies are included so as to make as many features in Guacamole available to the installer.
In terminal, as root, install dependencies with the following:
For Fedora 21 (Fedora 23 or newer, substitute dnf for yum):
sudo yum install tomcat gcc cairo-devel libjpeg-devel libpng-devel uuid-devel freerdp-devel pango-devel libssh2-devel libtelnet-devel libvncserver-devel pulseaudio-libs-devel openssl-devel libvorbis-devel libwebp-devel wget
Some packages may be already included in your Amahi install. If this is so Fedora / Amahi will skip that package.
Preparing Amahi
Login to your Amahi Dashboard and choose "Set Up" in the upper right. Now select the "Apps" tab. Click on "Webapps" and on the page that comes up choose the "New Web App" button at the bottom. Fill in the name (guacamole) and leave everything else as it is.
- Note: If you do not see the "Webapps" option under "Apps" then you need to activate "Advanced Settings" under the "Settings" tab of your Amahi dashboard.
Setting up MySQL Authentication
Creating the Database
hda-create-db-and-user guacdb
Installing MySQL Authentication Module
Create a working directory and move there
sudo mkdir -p /var/hda/web-apps/guacamole/sqlauth && cd /var/hda/web-apps/guacamole/sqlauth
Download Guacamole's authorization module
sudo wget http://sourceforge.net/projects/guacamole/files/current/extensions/guacamole-auth-jdbc-0.9.9.tar.gz
Unpack it
sudo tar -zxf guacamole-auth-jdbc-0.9.9.tar.gz
Download MySQL and Java Connector
sudo wget http://dev.mysql.com/get/Downloads/Connector/j/mysql-connector-java-5.1.38.tar.gz
Unpack it
sudo tar -zxf mysql-connector-java-5.1.38.tar.gz
Create directories for the extensions in Tomcat's folders
sudo mkdir -p /usr/share/tomcat/.guacamole/{extensions,lib}
Move the modules to their respective directories.
sudo mv guacamole-auth-jdbc-0.9.9/mysql/guacamole-auth-jdbc-mysql-0.9.9.jar /usr/share/tomcat/.guacamole/extensions/ sudo mv mysql-connector-java-5.1.38/mysql-connector-java-5.1.38-bin.jar /usr/share/tomcat/.guacamole/lib/
Restart MariaDB
sudo systemctl restart mariadb.service
Loading Guacamole's schema into the MySQL Tables
The schema for MySQL was downloaded in the previous process. Just change directories to the files location
cd /var/hda/web-apps/guacamole/sqlauth/guacamole-auth-jdbc-0.9.9/mysql/schema/
and run the following command:
sudo cat ./*.sql | mysql -u root -p hda
Installing Guacamole Server
Guacamole uses "guacd", a Guacamole server and a Guacamole Client for users to connect to the "guacd" server. We first install Guacamole Server.
Change Directories
cd /var/hda/web-apps/guacamole
Download Guacamole Server
sudo wget https://sourceforge.net/projects/guacamole/files/current/source/guacamole-server-0.9.9.tar.gz
Unpackage it
tar -xzf guacamole-server-0.9.9.tar.gz
Move to the Guacamole source code directory
cd guacamole-server-0.9.9/
Configure, make and install it.
sudo ./configure --with-init-dir=/etc/init.d sudo make sudo make install sudo ldconfig
Installing Guacamole Client
Create a new directory and move to it.
sudo mkdir -p /var/lib/guacamole && cd /var/lib/guacamole/
Download Guacamole Client.
sudo wget http://sourceforge.net/projects/guacamole/files/current/binary/guacamole-0.9.9.war -O guacamole.war
Create a symbolic link of the file for Tomcat.
sudo ln -s /var/lib/guacamole/guacamole.war /var/lib/tomcat/webapps/
Guacamole's Configuration File
Create a directory for the configuration file.
sudo mkdir -p /etc/guacamole/
Create a file called "guacamole.properties" in that directory
sudo vi /etc/guacamole/guacamole.properties
Press the i key to begin inserting text into the guacamole.properties file and include the following contents:
# MySQL properties mysql-hostname: localhost mysql-port: 3306 mysql-database: guacdb mysql-username: guacdb mysql-password: guacdb # Additional settings mysql-default-max-connections-per-user: 0 mysql-default-max-group-connections-per-user: 0
If you use vi for creating this file, press the Esc key to get back in command mode and :wq to write the changes and quit vi.
Now create a symbolic link of this file for Tomcat
sudo ln -s /etc/guacamole/guacamole.properties /usr/share/tomcat/.guacamole/
Starting Guacamole Server
Restart Tomcat.
sudo service tomcat restart
Start Guacamole Server. sudo /etc/init.d/guacd start
Configure Guacamole Server to start at boot.
sudo chkconfig tomcat on # chkconfig guacd on
Configuring Guacamole and Amahi
Create Symbolic links between guacamole in Tomcat and Amahi's webapp directory
| bash code |
|---|
sudo ln -s /var/lib/tomcat/webapps/guacamole/* /var/hda/web-apps/guacamole/html
|
As root, create .htaccess file in /var/hda/web-apps/guacamole/html
| bash code |
|---|
vi /var/hda/web-apps/guacamole/html/.htaccess
|
Press the i key to begin inserting text into the .htaccess file and include the following:
RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule (.*) http://%{HTTP_HOST}:8080/guacamole [R,L]
Again, if you use vi for creating this file, press the Esc key to get back in command mode and :wq to write the changes and quit vi.
Make sure the owner of all the file is apache and the group is users.
| bash code |
|---|
sudo chown -R apache:users /var/hda/web-apps/guacamole
|
Restart Apache
| bash code |
|---|
sudo service httpd restart
|
Logging In to Guacamole
You can access the web login screen for Guacamole from the server at http://localhost:8080/guacamole
From other computers in the network you can access Guacamole by http://****:8080/guacamole (Where the "****" is the ip address of your Amahi server).
The default user is "guacadmin", with the default password of "guacadmin". You can change your password by editing your own user in the administration screen.
With everything configured correctly you should be able to access the web login screen through Amahi at http://guacamole.yourhdaname.com:8080/guacamole/
Port Forwarding
If you want Guacamole's web interface to be accessible outside of your LAN you will have to forward a random, unused port (1111, for example) to port 8080 in your router. Then when you access Guacamole from outside your LAN you will need to add "/guacamole" to the end of your url. (serverblahblah.yourhda.com:1111/guacamole) If you do not add "/guacamole" to your url, you will see a blank page since you did not specify which application in Tomcat you wanted to access.
