Guacamole Setup on CentOS 7

Here is a step by step guide how to install and configure Apache Guacamole on CentOS7

Step 1. Of course, you need to install a new system. During the installation, remember to set few things to avoid manual change later.

- set time zone

- set network configuration

- set storage

- select minimal server packages

- begin installation

- set root password

Step 2. After installation reboot, it's a good practice to keep your system up-to-date.

# yum update -y

Reboot

Step 3. Install some dependency packages.  The following list all packages to be installed. 

# yum install -y cairo-devel

# yum install -y libjpeg-turbo-devel

# yum install -y libpng-devel

# yum install -y libtool

# yum install -y uuid-devel

# yum install epel-release

# rpm -v --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro

# rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

# yum install -y ffmpeg-devel

# yum install -y freerdp-devel

# yum install -y pango-devel

# yum install -y libssh2-devel

# yum install -y libtelnet-devel

# yum install -y libvncserver-devel

# yum install -y libwebsockets-devel

# yum install -y pulseaudio-libs-devel

# yum install -y openssl-devel

# yum install -y libvorbis-devel

# yum install -y libwebp-devel

Step 4. Download Apache Guacamole Server source and get it install

you might need this tool.
# yum install -y wget

Download Source (2 ways)

download from website http://guacamole.apache.org or from github

download from website

after getting the url from browser download manager, you can download with wget ( for me, i have the url)

# wget http://apache.communilink.net/guacamole/1.1.0/source/guacamole-server-1.1.0.tar.gz

# tar -xzf guacamole-server-1.1.0.tar.gz

# cd guacamole-server-1.1.0/

download from github

# git clone git://github.com/apache/guacamole-server.git

# cd guacamole-server/

# autoreconf -fi
# ./configure --with-init-dir=/etc/init.d

You should get similar result

# make

# make install

# ldconfig

Now the Guacamole Server is ready.

Step 5. Download Apache Guacamole Client WAR

Download client from website

after getting the url from browser download manager, you can download with wget ( for me, i have the url)

# wget http://ftp.cuhk.edu.hk/pub/packages/apache.org/guacamole/1.1.0/binary/guacamole-1.1.0.war

Step 6. Install Tomcat

# yum install -y tomcat

# yum install -y tomcat-admin-webapps

# yum install -y tomcat-webapps

# vi /usr/share/tomcat/conf/tomcat-users.xml

Uncomment these lines and change the password for admin

<role rolename="admin"/> <role rolename="admin-gui"/> <role rolename="admin-script"/> <role rolename="manager"/> <role rolename="manager-gui"/> <role rolename="manager-script"/> <role rolename="manager-jmx"/> <role rolename="manager-status"/> <user name="admin" password="**********" roles="admin,manager,admin-gui,admin-script,manager-gui,manager-script,manager-jmx,manager-status" /> </tomcat-users>

# systemctl enable tomcat

# systemctl restart tomcat

Step 7. Open port 8080 on firewall

# firewall-cmd --add-port=8080/tcp --permanent

# firewall-cmd --reload

now your tomcat should be available

http://:8080/

mine is http://10.10.10.13:8080/

and the manager app should also work at http://10.10.10.13:8080/manager/html

After input the admin user name and  password,

# cp guacamole-1.1.0.war /usr/share/tomcat/webapps/guacamole.war

Then refresh the http://10.10.10.13:8080/manager/html

You will see the app deployed

# mkdir /etc/guacamole

# vi /etc/guacamole/guacamole.properties

# Hostname and port of guacamole proxy guacd-hostname: localhost guacd-port:     4822

# vi /etc/guacamole/user-mapping.xml

(this is for testing purpose, change the red parts as needed)

<user-mapping>    <authorize             username="testuser"             password="testpass123">         <connection name="VNC TEST”>             <protocol>vnc</protocol>             <param name="hostname">172.16.10.10</param>             <param name="port">5900</param>             <param name="password">******</param>         </connection>         <connection name="SSH TEST">             <protocol>ssh</protocol>             <param name="hostname">10.10.10.25</param>             <param name="port">22</param>         </connection>         <connection name="RDP TEST">             <protocol>rdp</protocol>             <param name="hostname">172.16.10.19</param>             <param name="port">3389</param>         </connection>     </authorize> </user-mapping>

# systemctl enable guacd

# systemctl restart tomcat guacd

Step 8.  Testing - without Database

http://10.10.10.13:8080/guacamole

Try to click any of connections for testing 

During session connected, you can use CTRL+ALT+SHIFT to call the GUACAMOLE menu for disconnections (under top right corner choose testuser->disconnect) 

Step 9 - Integrating with MySQL/MariaDB for larger scale of usage.

# yum install -y mariadb

# systemctl start mariadb

Or install mysql-server (non-bundled in CentOS7)

# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

# rpm -ivh mysql-community-release-el7-5.noarch.rpm

# yum update

# yum install mysql-server

# systemctl start mysqld

# mysql_secure_installation

[root@guaca ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL       SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we'll need the current password for the root user.  If you've just installed MySQL, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none):  OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. Set root password? [Y/n]  New password:  Re-enter new password:  Password updated successfully! Reloading privilege tables..  ... Success! By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them.  This is intended only for testing, and to make the installation go a bit smoother.  You should remove them before moving into a production environment. Remove anonymous users? [Y/n]   ... Success! Normally, root should only be allowed to connect from 'localhost'.  This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n]   ... Success! By default, MySQL comes with a database named 'test' that anyone can access.  This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n]   - Dropping test database... ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist  ... Failed!  Not critical, keep moving...  - Removing privileges on test database...  ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n]   ... Success! All done!  If you've completed all of the above steps, your MySQL installation should now be secure. Thanks for using MySQL! Cleaning up...
