This script was forked from MysticRyuujin but this is a version that I am planning to maintain and support for long. Credits to him for creating the script and making it, this is just a repo of the same thing but wth a maintained version.
You can also check out this other Guacamole-Setup repo which sets up a complete Virtual Desktop/Jump Server appliance with MFA, Active Directory integration & Nginx SSL reverse proxy for more inspiration.
NOTE: The fixes below are not to be used UNLESS you're having issues, don't run these for no reason, use the distro maintainers version unless there's a reason not to.
sudo add-apt-repository ppa:remmina-ppa-team/remmina-next
sudo apt-get update
sudo apt-get install freerdp2-dev freerdp2-x11
sudo bash -c 'echo "deb http://deb.debian.org/debian buster-backports main" >> /etc/apt/sources.list.d/backports.list'
sudo apt update
sudo apt -y -t buster-backports install freerdp2-dev libpulse-dev
Script for installing Guacamole 1.5.5 on Ubuntu 16.04 or newer (with MySQL, or remote MySQL). It should also work on pure Debian, Raspbian, Linux Mint (18/LMDE 4 or newer) or Kali Linux. I have tested this with Debian 10.3.0 (Buster). If other versions don't work please open an issue. It is likely due to a required library having a different name.
Run script, enter MySQL Root Password and Guacamole User password. Guacamole User is used to connect to the Guacamole Database. Be sure to save these!
The script works well on Ubuntu 20, 22, and maybe 23 because those have tomcat9 preinstalled which makes installing it much easier.
By default the script will not install MFA support (QR code for Google/Microsoft Authenticator, Duo Mobile, etc. or Duo Push), if you do want MFA support you can use the -t or --totp or for Duo -d or --duo flags on the command line. Or modify the script variables installTOTP=true or installDuo=true. Do not install both!
Here's a cool PowerShell module for using the Guacamole API: https://github.com/UpperM/guacamole-powershell
Does not work if you have MFA turned on (however, you can authenticate via the gui and get a token to use it that way).
wget https://git.io/fxZq5 -O guac-install.sh
chmod +x guac-install.sh
Interactive (asks for passwords):
./guac-install.sh
Non-Interactive (values provided via cli):
./guac-install.sh --mysqlpwd password --guacpwd password --nomfa --installmysql
OR
./guac-install.sh -r password -gp password -o -i
Once installation is done you can access Guacamole by browsing to: http://<host_or_ip>:8080/guacamole/
The default credentials are guacadmin as both username and password. Please change them or disable guacadmin after install!
Script for upgrading currently installed Guacamole instance (previously installed via this script/guide). This will also now update the TOTP or Duo extensions if used.
If looks for the tomcat folder in /etc/ (E.G. /etc/tomcat7 or /etc/tomcat8) hopefully that works to identify the correct tomcat version/path 😄 I'm open to suggestions/pull requests for a cleaner method.
Install MySQL:
-i or --installmysql
Do NOT install MySQL:
-n or --nomysql
MySQL Host:
-h or --mysqlhost
MySQL Port:
-p or --mysqlport
MySQL Root Password:
-r or --mysqlpwd
Guacamole Database:
-db or --guacdb
Guacamole User:
-gu or --guacuser
Guacamole User Password:
-gp or --guacpwd
No MFA (No TOTP + Duo):
-o or --nomfa
Install TOTP:
-t or --totp
Install Duo:
-d or --duo
NOTE: Only the switches for MySQL Host, MySQL Port and Guacamole Database are available in the upgrade script.
- Upgrading from versions older than a couple dot fixes ago have not been tested with this script, use at your own risk and take backups first!
wget https://raw.githubusercontent.com/MysticRyuujin/guac-install/master/guac-upgrade.sh
chmod +x guac-upgrade.sh
Interactive (asks for passwords):
./guac-upgrade.sh
Non-Interactive (MySQL root password provided via cli):
./guac-upgrade.sh --mysqlpwd password
Make sure that you configure your reverse proxy (NGinx or Apache) as per the Official Documentation
For Nginx:
location /guacamole/ {
proxy_pass http://HOSTNAME:8080/guacamole/;
proxy_buffering off;
proxy_http_version 1.1;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $http_connection;
access_log off;
}
For Apache:
<Location /guacamole/>
Order allow,deny
Allow from all
ProxyPass http://HOSTNAME:8080/guacamole/ flushpackets=on
ProxyPassReverse http://HOSTNAME:8080/guacamole/
</Location>
Guacamole only supports ssh-dss and ssh-rsa, and both have been disabled in Ubuntu 22.04.
In the meantime a workaround is adding HostKeyAlgorithms +ssh-rsa to the end of /etc/ssh/sshd_config on the Ubuntu machine and restart sshd.
