Install Drupal CMS on Ubuntu 16.04 LTS with Nginx, MariaDB, PHP 7.1 and Let’s Encrypt SSL/TLS

by Posted on

If WordPress is not meeting your needs, Drupal might… It’s a content management system that allows webmasters and designers to create dynamic PHP based websites and apps…

Drupal is a powerful and popular CMS use by many webmasters to create powerful websites and blogs. For those webmasters and website owners looking to run and manage dynamic, PHP-based websites and blogs easily may want to take a look at Drupal CMS.

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

This brief tutorial is going to show students and new users how to install Drupal on Ubuntu 16.04 LTS with Nginx, MariaDB, PHP and Let’s Encrypt support. When you’re done, your website will automatically be configured to use HTTPS for all traffic.

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

Step 1: Install Nginx

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

sudo apt 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

Drupal 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 mysql.service
sudo systemctl start mysql.service
sudo systemctl enable mysql.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

Restart MariaDB server

sudo systemctl restart mysql.service

Step 3: Install PHP 7.1-FPM and Related Modules

PHP 7.1 isn’t available on Ubuntu default repositories… in order to install it, you will have to get it from third-party repositories.

Run the commands below to add the below third party repository to upgrade to PHP 7.1

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php

Then update and upgrade to PHP 7.1

sudo apt update

Run the commands below to install PHP 7.1 and related modules.

sudo apt install php7.1-fpm php7.1-common php7.1-mbstring php7.1-xmlrpc php7.1-soap php7.1-gd php7.1-xml php7.1-intl php7.1-mysql php7.1-cli php7.1-mcrypt php7.1-ldap php7.1-zip php7.1-curl

After install PHP, run the commands below to open Nginx PHP default file.

sudo nano /etc/php/7.1/fpm/php.ini

Then change the following lines below in the file and save. You may increase the value to suite your environment.

max_execution_time = 180
max_input_time = 60
memory_limit = 256M
upload_max_filesize = 64M
cgi.fix_pathinfo = 0

Step 4: Create Drupal 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 Drupal 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 drupal

CREATE DATABASE drupal;

Create a database user called drupaluser with new password

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

Then grant the user full access to the database.

GRANT ALL ON drupal.* TO 'drupaluser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

Step 5: Download Drupal Latest Release

Next, visit Drupal site and download the latest package…. or run the commands below to download and extract Drupal content.

After downloading, run the commands below to extract the downloaded file and move it into a new Drupal root directory.

cd /tmp && cd /tmp && wget https://ftp.drupal.org/files/projects/drupal-8.4.2.tar.gz
tar -zxvf drupal*.gz
sudo mv drupal-8.4.2 /var/www/html/drupal

Then run the commands below to set the correct permissions for Drupal to function properly.

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

Step 6: Configure Nginx Drupal Site

Finally, configure Nginx configuration file for Drupal. This file will control how users access Drupal content. Run the commands below to create a new configuration file called drupal

sudo nano /etc/nginx/sites-available/drupal

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/drupal;
    index  index.php index.html index.htm;
    server_name  example.com www.example.com;

    location / {
    try_files $uri /index.php?$query_string;        
    }

    location @rewrite {
               rewrite ^/(.*)$ /index.php?q=$1;
        }

    location ~ [^/]\.php(/|$) {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~ ^/sites/.*/files/styles/ { # For Drupal >= 7
               try_files $uri @rewrite;
        }

    location ~ ^(/[a-z\-]+)?/system/files/ { # For Drupal >= 7
        try_files $uri /index.php?$query_string;
        }
}

Save the file and exit.

Step 7: Enable the Drupal Site

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

sudo ln -s /etc/nginx/sites-available/drupal /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 Drupal 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
https://letsencrypt.org/documents/LE-SA-v1.2-November-15-2017.pdf. You must

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"
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le

The highlighted code block should be added to your Nginx Drupal site configuration file automatically by Let’s Encrypt certbot. Your Drupal site is ready to be used over HTTPS.

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

    location / {
    try_files $uri /index.php?$query_string;        
    }

    location @rewrite {
               rewrite ^/(.*)$ /index.php?q=$1;
        }

    location ~ [^/]\.php(/|$) {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~ ^/sites/.*/files/styles/ { # For Drupal >= 7
               try_files $uri @rewrite;
        }

    location ~ ^(/[a-z\-]+)?/system/files/ { # For Drupal >= 7
        try_files $uri /index.php?$query_string;
        }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

    if ($scheme != "https") {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    # Redirect non-https traffic to https
    # if ($scheme != "https") {
    #     return 301 https://$host$request_uri;
    # } # managed by Certbot

}

After that, open your browser and browse to your domain name to start Drupal configuration wizard. You should see Drupal setup wizard… Please follow the wizard carefully.

https://example.com
drupal ubuntu let's encrypt

Follow the onscreen wizard until you’re done.

ubuntu drupal let's encrypt

Enter the database connection info and continue.

drupal ubuntu let's encrypt

Create your Drupal site admin account and website name.

drupal let's encrypt

Finish

drupal let's encrypt

Congratulations! You’ve successfully installed Drupal with Let’s Encrypt free SSL certificates.

To setup a process to automatically renew the certificates, add a cron job to execute the renewal process.

sudo crontab -e

Then add the line below and save.

0 1 * * * /usr/bin/certbot renew & > /dev/null

The cron job will attempt to renew 30 days before expiring

Enjoy!
