Gibbon is an open source platform for schools. Founded in 2010 in response to lack of a powerful, usable and open source school platform.
Designed to be flexible, extensible and themable from the beginning which aims to help teachers do their jobs in all schools no matter their size or resources.
Several main features of Gibbon are:
- Learn
- Assess
- People
- Admin
- and other features like messaging and finance
You can learn more about Gibbon features from Gibbon features page.
Objective
In this tutorial we’ll learn how to install Gibbon on Ubuntu 14.04. We will also install and configure its prerequisites.
Prerequisites
We will install Gibbon in fresh installation of Ubuntu Server 14.04. We also need these applications to be able to run Gibbon:
- Apache 2
- MySQL 5
- PHP >= 5.5
- Gibbon also require the following php libraries
- php5-curl
- php5-gd
Update Base System
Before we install Gibbon, let’s update the system to the latest update.
$ sudo apt-get update
$ sudo apt-get -y upgrade
Install Apache 2
After applying latest update to our base system, lets’s start installing Apache 2 and required libraries.
$ sudo apt-get -y install apache2 apache2-bin apache2-data apache2-mpm-prefork libaio1 libapache2-mod-php5 libapr1 libaprutil1 libdbd-mysql-perl libdbi-perl libhtml-template-perl libmysqlclient18 libterm-readkey-perl libwrap0 ssl-cert tcpd
We can check the Apache 2 service status using command below:
sudo service apache2 status
* apache2 is running
We can also check which port Apache 2 is listening on using the command below.
sudo netstat -naptu | grep apache
tcp6 0 0 :::80 :::* LISTEN 14873/apache2
Install MySQL 5.6
We will install and use the MySQL 5.6 as database for Gibbon.
We will use a MySQL Server 5.6 since MySQL 5.6 is the most up to date version of MySQL shipped with Ubuntu 14.04 Trusty Tahr.
$ sudo apt-get -y install mysql-server-5.6
We need to setup MySQL root
password. Please input password for MySQL root
user.

Verify root
password.

Securing MySQL Installation.
We will secure the MySQL installation by running mysql_secure_installation
.
Enter root password that we set on installation:
$ 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...
Since we already have root password set, answer this part with n
.
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
You already have a root password set, so you can safely answer 'n'.
Change the root password? [Y/n] n
... skipping.
Remove the anonymous user to improve security. This will make sure people or application have correct username and password to login to MySQL. Answer with Y
.
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] Y
... Success!
We also want remove the root
login from remote machine. Answer with Y
.
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] Y
... Success!
Previously the test
database created automatically by MySQL installation, but MySQL 5.6 does not create a test
database. We can still choose Y
, it will throw error but that’s fine.
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] Y
- 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!
The last step is to reload MySQL privilege table.
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] Y
... 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...
Create Database for Gibbon
Now we have a secure MySQL installation, time to create database and user for gibbon itself.
Login to MySQL using root
credential.
$ mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 58
Server version: 5.6.30-0ubuntu0.14.04.1 (Ubuntu)

mysql>
Create new database named gibbon
using command below:
mysql> CREATE DATABASE gibbon;
Query OK, 1 row affected (0.00 sec)
Create a User for Gibbon
The database for gibbon is ready, let’s create a username, password and grant privileges to gibbon
database.
Don’t forget to change the password gibbon123secret
below with better password.
mysql> GRANT ALL PRIVILEGES ON `gibbon`.* TO 'gibbon'@'localhost' IDENTIFIED BY 'gibbon123secret';
Query OK, 0 rows affected (0.00 sec)
We need to run FLUSH PRIVILEGES
command so that the privileges table will be reloaded by MySQL and we can use new credential.
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
Exit from MySQL console by typing \q
mysql> \q
Install PHP 5
The last component that we have to install before we can install gibbon is PHP 5. We will install PHP 5 and several common PHP libraries.
$ sudo apt-get -y install php5-cli php5-common php5-json php5-mysql php5-readline
Install additional php libraries:
$ sudo apt-get -y install php5-curl php5-gd
Restart the Apache 2 process so the changes will be applied
$ sudo service apache2 restart
Install gibbon
All prerequisites is already installed. We’re ready to install gibbon. The latest stable version of gibbon is available Gibbon download page.
At the time of this writing, the latest stable version is version 13.0.01, let’s download the gibbon compressed file using wget.
$ wget -c https://github.com/GibbonEdu/core/archive/v13.0.01.zip
Extract the downloaded file using unzip
. If your system don’t have unzip
yet, you can install unzip using command below:
$ sudo apt-get -y install unzip
Extract gibbon using unzip
$ unzip v13.0.01.zip
Move extracted directory to Apache directory.
$ sudo mv core-13.0.01 /var/www/gibbon
Change ownership of gibbon
directory to www-data
user and group.
$ sudo chown -R www-data:www-data /var/www/gibbon
The gibbon files are ready, now let’s create Apache Virtual Host configuration to serve gibbon.
Configure Apache Virtual Host for http Only
Create a new apache configuration file on /etc/apache2/sites-available/gibbon.conf
with contents below.
<VirtualHost *:80>
ServerName gibbon.exampleserver.xyz
DocumentRoot /var/www/gibbon
<Directory /var/www/gibbon>
Options -Indexes +FollowSymLinks +MultiViews
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/gibbon.exampleserver.xyz-error.log
CustomLog ${APACHE_LOG_DIR}/gibbon.exampleserver.xyz-access.log combined
</VirtualHost>
Don’t forget to change gibbon.exampleserver.xyz
above with the domain name that you use for your gibbon installation.
Enable the site using a2ensite
command.
$ sudo a2ensite gibbon
Reload apache2
process so it read the new virtualhost configuration:
$ sudo service apache2 reload
Gibbon Setup Wizard
Open theGibbon URL, we will be redirected to the Gibbon setup wizard.
Step 1 is requirement checking and language settings. We should already pass all requirements now and we will use English as system language.
HP_NO_IMG/data/uploads/users/5fb651f8-5ad5-41bd-9990-35c934077f44/61642843.png” alt=”” />
Step 2 is database configuration, enter database name and credentials that we created before.
HP_NO_IMG/data/uploads/users/5fb651f8-5ad5-41bd-9990-35c934077f44/1943246166.png” alt=”” />
Step 3 is account configuration, system settings and organization settings. You can input the data based on your requirements.
HP_NO_IMG/data/uploads/users/5fb651f8-5ad5-41bd-9990-35c934077f44/582498288.png” alt=”” />
Step 4. Installation finished we can click the link to go to Gibbon homepage.
HP_NO_IMG/data/uploads/users/5fb651f8-5ad5-41bd-9990-35c934077f44/67726052.png” alt=”” />
From Gibbon homepage we can login using admin credential that we create on setup wizard.
HP_NO_IMG/data/uploads/users/5fb651f8-5ad5-41bd-9990-35c934077f44/1383683764.png” alt=”” />
After a successful login we will go to Gibbon dashboard where we can manage class and also administrative settings.

Configure https only site for gibbon
Secure connection is now a requirement for web application. Last step that we will do in this tutorial is changing the connection to only use https.
We assume that you already have SSL certificate and private key.
Let’s create new apache virtual host configuration on /etc/apache2/sites-available/gibbon-ssl.conf
with contents below. Don’t forget to change:
ServerName
SSLCertificateFile
SSLCertificateChainFile
SSLCertificateKeyFile
<VirtualHost *:80>
ServerName gibbon.exampleserver.xyz
Redirect permanent / https://gibbon.exampleserver.xyz/
</VirtualHost>
<VirtualHost *:443>
ServerName gibbon.exampleserver.xyz
DocumentRoot /var/www/gibbon
<Directory /var/www/gibbon>
Options -Indexes +FollowSymLinks +MultiViews
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/gibbon.exampleserver.xyz-error.log
CustomLog ${APACHE_LOG_DIR}/gibbon.exampleserver.xyz-access.log combined
SSLEngine on
SSLCertificateFile /etc/apache2/ssl/gibbon.exampleserver.xyz.crt
SSLCertificateChainFile /etc/apache2/ssl/gibbon.exampleserver.xyz.crt
SSLCertificateKeyFile /etc/apache2/ssl/gibbon.exampleserver.xyz.key
Header always set Strict-Transport-Security "max-age=15768000"
</VirtualHost>
# intermediate configuration, tweak to your needs
SSLProtocol all -SSLv2 -SSLv3
SSLCipherSuite ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS
SSLHonorCipherOrder on
We will also disable gibbon
http only virtual host and enable the new virtual host config.
$ sudo a2dissite gibbon
$ sudo a2ensite gibbon-ssl
The new virtual host configuration need Apache mod_ssl
and mod_headers
modules. We need to enable those modules.
$ sudo a2enmod ssl
$ sudo a2enmod headers
Now, restart Apache 2 service so it will reload its configuration. We need to restart instead of reload since we enable new module.
$ sudo service apache2 restart
Summary
In this tutorial we learned how-to install gibbon on Ubuntu 14.04.
We installed all the prerequisites, create user and database on MySQL for Gibbon and also configure Apache 2 virtual hosts to be able to serve gibbon.
We also configured https settings for gibbon so we run Gibbon securely.
