Install Moodle on Ubuntu 17.04 | 17.10 with Nginx, MariaDB, PHP and Let's Encrypt SSL

Moodle is a free PHP based course management system (CMS) designed to help educators create great courses for students. Many reputable universities and colleges are using it to run their courses online. Students will also find it easy to use and work on. Teachers and students can also use it to collaborate and build great teaching materials.

This brief tutorial shows students and new users how to easily install Moodle CMS on Ubuntu 17.04 | 17.10 with Nginx, MariaDB, PHP and Let’s Encrypt SSL support.

In today’s environments, Moodle is frequently being installed with SSL/TLS encryption so that all traffic to and from the course materials is protected over HTTPS. Also, websites that use HTTPS may rank better with Google and other search engine providers.

This post covers installing the latest version of Moodle, which at the time of writing was at version 3.3.2+.

To get started with installing Moodle with Let’s Encrypt support, follow the steps below:

Step 1: Install Nginx

Moodle requires a webserver to function and the most popular webserver in use today is Nginx. So, go and install Nginx on Ubuntu by running the commands below:

sudo apt-get install nginx

Next, run the commands below to stop, start and enable Nginx service to always start up with the server boots.

sudo systemctl stop nginx.service
sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Step 2: Install MariaDB

Moodle also requires a database server to function. and MariaDB database server is a great place to start. To install it run the commands below.

sudo apt-get install mariadb-server mariadb-client

After installing, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.

sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

After that, run the commands below to secure MariaDB server.

sudo mysql_secure_installation

When prompted, answer the questions below by following the guide.

Enter current password for root (enter for none): Just press the Enter
Set root password? [Y/n]: Y
New password: Enter password
Re-enter new password: Repeat password
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]: Y
Reload privilege tables now? [Y/n]: Y

After that, open MariaDB default configuration file by running the commands below:

sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf

Then add the below lines just below [mysqld] section.

default_storage_engine = innodb
innodb_file_per_table = 1
innodb_file_format = Barracuda
innodb_large_prefix = 1

Save the file and exit.

Restart MariaDB server

sudo systemctl restart mariadb.service

Step 3: Install PHP-FPM and Related Modules

Moodle also requires PHP to function. To install PHP and related modules run the commands below

sudo apt-get install php-fpm php-common php-mbstring php-xmlrpc php-soap php-gd php-xml php-intl php-mysql php-cli php-mcrypt php-ldap php-zip php-curl

Step 4: Create Moodle Database

Now that you’ve install all the packages that are required, continue below to start configuring the servers. First run the commands below to create Moodle database.

Run the commands below to logon to the database server. When prompted for a password, type the root password you created above.

sudo mysql -u root -p

Then create a database called moodle

CREATE DATABASE moodle;

Create a database user called moodleuser with new password

CREATE USER 'moodleuser'@'localhost' IDENTIFIED BY 'new_password_here';

Then grant the user full access to the database.

GRANT ALL ON moodle.* TO 'moodleuser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

Step 5: Download Moodle Latest Release

Next, run the commands below to download Moodle latest release. The commands below to download Moodle archive package.

cd /tmp && wget https://download.moodle.org/download.php/direct/stable33/moodle-latest-33.tgz

Then run the commands below to extract the downloaded file to Nginx default root.

tar -zxvf moodle-latest-33.tgz
sudo mv moodle /var/www/html/moodle
sudo mkdir /var/www/html/moodledata

Change modify the directory permission.

sudo chown -R www-data:www-data /var/www/html/moodle/
sudo chmod -R 755 /var/www/html/moodle/
sudo chown www-data /var/www/html/moodledata

Step 6: Configure Nginx

Finally, configure Apahce2 site configuration file for Moodle. This file will control how users access Moodle content. Run the commands below to create a new configuration file called moodle

sudo nano /etc/nginx/sites-available/moodle.conf

Then copy and paste the content below into the file and save it. Replace the highlighted line with your own domain name and directory root location.

server {
    listen 80;
    listen [::]:80;
    root /var/www/html/moodle;
    index  index.php index.html index.htm;
    server_name  example.com www.example.com;

    location / {
    try_files $uri $uri/ =404;        
    }
 
    location /dataroot/ {
    internal;
    alias /var/www/html/moodledata/
    }

    location ~ [^/]\.php(/|$) {
    fastcgi_split_path_info  ^(.+\.php)(/.+)$;
    fastcgi_index            index.php;
    fastcgi_pass             unix:/var/run/php/php7.1-fpm.sock;         #Ubuntu 17.10
 #  fastcgi_pass             unix:/var/run/php/php7.0-fpm.sock;         #Ubuntu 17.04
    include                  fastcgi_params;
    fastcgi_param   PATH_INFO       $fastcgi_path_info;
    fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

}

Save the file and exit.

Step 7: Enable the Moodle site

After configuring the VirtualHost above, enable it by running the commands below

sudo ln -s /etc/nginx/sites-available/moodle /etc/nginx/sites-enabled/

Step 8 : Restart Nginx

To load all the settings above, restart Nginx by running the commands below.

sudo systemctl restart nginx.service

STEP 9: OBTAIN AND CONFIGURE LET’S ENCRYPT SSL CERTIFICATES

Now that the Moodle configuration is done, continue below to get Let’s Encrypt installed and configured. Let’s Encrypt now provides a Nginx module to automate this process. To get the client/module installed on Ubuntu, run the commands below

sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-nginx

After that run the commands below to obtain your free Let’s Encrypt SSL/TLS certificate for your site.

sudo certbot --nginx -m admin@example.com -d example.com -d www.example.com

After running the above commands, you should get prompted to accept the licensing terms. If everything is checked, the client should automatically install the free SSL/TLS certificate and configure the Nginx site to use the certs.

Please read the Terms of Service at

This is how easy is it to obtain your free SSL/TLS certificate for your Nginx powered website.

Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.
-------------------------------------------------------------------------------
1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.
-------------------------------------------------------------------------------
Select the appropriate number [1-2] then [enter] (press 'c' to cancel): 2

Pick option 2 to redirect all traffic over HTTPS. This is important!

After that, the SSL client should install the cert and configure your website to redirect all traffic over HTTPS.

Congratulations! You have successfully enabled https://example.com and
https://www.example.com

You should test your configuration at:
https://www.ssllabs.com/ssltest/analyze.html?d=example.com
https://www.ssllabs.com/ssltest/analyze.html?d=www.example.com
-------------------------------------------------------------------------------

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/example.com/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/example.com/privkey.pem
   Your cert will expire on 2018-02-24. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot again
   with the "certonly" option. To non-interactively renew *all* of
   your certificates, run "certbot renew"
