How to Install Joomla with Nginx and Cloudflare on Ubuntu Linux

This article explains installing Joomla with Nginx and Cloudflare support on Ubuntu Linux.

Joomla — a free, mobile-ready, open-source content management system (CMS), is a great way to build beautiful websites. However, to add an extra layer of security and improve your user experience, you may want to add Cloudflare, CDN / SSL, and security features.

Installing Joomla with Nginx and Cloudflare on Ubuntu Linux is a great way to build secure and fast websites. By using Cloudflare’s CDN and SSL support, as well as Nginx’s powerful web server, you can improve the user experience and add an extra layer of security to your site.

This setup applies to other CMSs and plain HTML sites, making it a versatile solution for web developers and website owners.

When you’re ready to set up your server and Cloudflare to use Origin Certificate, follow the steps below:

How to sign up for Cloudflare

The first step in this tutorial is to sign up for a Cloudflare account. This post assumes that you already have registered a domain name. If you don’t, then go and get one before continuing further.

If you already have a Cloudflare account, then skip the registration below.

https://dash.cloudflare.com/sign-up

Type in your email address and click Create Account.

Once the account is created and you’ve verified your email address and logged back into the Cloudflare account, click the button or link (Add a Site) to add a site to your account.

Next, type in the domain name you have registered. Again, Cloudflare service will help speed up and protect the site you add.

Next, Cloudflare will query your domain DNS provider for the records in the DNS table. Cloudflare should find the domain and import the records into its DNS systems if it is online.

After that, select the plan you want to use for the site. For this tutorial, we will be using the Cloudflare free plan.

You should see two nameservers provided to you by Cloudflare when you’re done. You need to log on to your domain provider’s portal. Then, where you have your domain, replace the nameservers with the ones Cloudflare gives you.

For example, our example.com site is hosted with Google Domains. Log on to your Google Domains account and select use custom nameservers.

You’ll have the option to enter the nameservers provided by Cloudflare. Save your changes when you’re done.

Once you’ve saved your custom nameserver changes, return to your Cloudflare account and wait for Cloudflare to see the changes. Depending on your domain provider, it takes up to an hour for the DNS changes to be visible on Cloudflare.

Once all is ready, you’ll see your site status as Active.

You should also see your Cloudflare account with DNS entries when everything is done, as shown below. Your DNS records might have more entries than the two below. However, these two entries are the most important for running your website.

After that, click on the Crypto tab and choose to enable Full (strict) SSL. This should turn on SSL for the site.

While still on the Crypto tab, scroll down to Origin Certificates. Then click the button to create the Certificate.

Use the free TLS certificate signed by Cloudflare to install it on your origin server. Origin Certificates are only valid for encryption between Cloudflare and your origin server.

Next, let Cloudflare generate a private key and a CSR for the domain. Click Next.

Then, copy and paste these into a text file onto your server.

Run the commands below on Ubuntu to create the Private key, Certificate, and Origin pull files (3 files). Then, copy and paste each content into the respective file. And save.

For the Private key file. Run this, copy and paste the private key given to you into the file, and save.

sudo nano /etc/ssl/private/cloudflare_key_example.com.pem

For the certificate file, run this copy, paste the certificate content into the file, and save.

sudo nano /etc/ssl/certs/cloudflare_example.com.pem

You’ll also want to download the Cloudflare Origin Pull certificate. You can download that from the link below:

Set up authenticated Origin pulls · Cloudflare SSL docs

Zone-Level — Cloudflare certificate

Under Zone-level certificate, expand the certificate button and copy its content.

Next, run the commands below to create an origin-pull-ca.pem file, paste the certificate content into the file below, and save.

sudo nano /etc/ssl/certs/origin-pull-ca.pem

Once done, you should have three files. The cloudflare_key_example.com.pem, cloudflare_example.com.pem and origin-pull-ca.pem.

We will use these files in the Nginx config below.

Pull the certificate files after saving the key, Certificate, and Origin. Continue below.

Still, on the Crypto page in your Cloudflare account, enable Always use HTTPS, and you may also change settings for HSTS but not necessary.

Next, turn on Authenticated Origin Pulls and Opportunistic Encryption, and continue.

Then, turn on Automatic HTTPS Rewrites and continue.

Next, move to the Page Rules tab. Then, create a new rule for the site. then type URL and choose Always Use HTTPS

http://* example.com/*

Always Use HTTPS

Save your settings, and you’re done with setting up Cloudflare.

Install and Configure Joomla

Now that Cloudflare is configured log on to your server and configure Joomla. First, install the Nginx HTTP server since we’re using Nginx for this post. To install the Nginx server, run the commands below:

sudo apt update
sudo apt install nginx

After installing Nginx, the commands below can be used to stop, start, and enable the 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

Now that Nginx has been installed browse your browser to the URL below to test whether the web server works.

https://localhost

If you see the page above, then Nginx is successfully installed.

How to Install MariaDB Database Server

Joomla also requires a database server to store its content. MariaDB is a great place to start if you want a genuinely open-source database server. To install MariaDB, run the commands below:

sudo apt-get install mariadb-server mariadb-client

After installing MariaDB, the commands below can stop and start the service and enable it to start when the server boots.

Run these on Ubuntu 16.04 LTS

sudo systemctl stop mysql.service
sudo systemctl start mysql.service
sudo systemctl enable mysql.service

Run these on Ubuntu 19.04 and 18.04 LTS

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

Next, run the commands below to secure the database server with a root password if you were not prompted to do so during the installation.

sudo mysql_secure_installation

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

Enter current password for root (enter for none): 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

Once MariaDB is installed, run the commands below to test whether the database server was installed.

sudo mysql -u root -p

Type the root password when prompted.

The server was successfully installed if you see a similar screen.

How to Install PHP 7.2-FPM and Related Modules

Joomla CMS is a PHP-based CMS, and PHP is required. However, PHP 7.2-FPM may not be available in Ubuntu default repositories. To run PHP 7.2-FPM on Ubuntu 16.04 and previous, you may need to run the commands below:

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

Then update and upgrade to PHP 7.2-FPM

sudo apt update

Next, run the commands below to install PHP 7.2-FPM and related modules.

sudo apt install php7.2-fpm php7.2-common php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-mysql php7.2-gd php7.2-xml php7.2-cli php7.2-zip

After installing PHP 7.2, run the commands below to open Nginx’s PHP default configuration file.

sudo nano /etc/php/7.2/fpm/php.ini

The lines below are a good setting for most PHP-based CMS. Update the configuration file with these and save.

file_uploads = On
allow_url_fopen = On
short_open_tag = On
memory_limit = 256M
cgi.fix_pathinfo = 0
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = America/Chicago

Restarting the Nginx web server whenever you change the PHP configuration file would be best. To do so, run the commands below:

sudo systemctl restart nginx.service

Once PHP is installed, create a test file called phpinfo.php in the Nginx default root directory. ( /var/www/html/)

sudo nano /var/www/html/phpinfo.php

Then, type the content below and save the file.

<?php phpinfo( ); ?>

Next, open your browser and browse to the server’s hostname or IP address followed by phpinfo.php

http://localhost/phpinfo.php

You should see the PHP default test page.

How to Create a Joomla Database

Once you’ve installed all the packages required for Joomla to function, continue below to start configuring the servers. First, run the commands below to create a blank Joomla database.

To log on to the MariaDB database server, run the commands below.

sudo mysql -u root -p

Then, create a database called joomla

CREATE DATABASE joomla;

Create a database user called joomlauser with a new password

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

Then, grant the user full access to the database.

GRANT ALL ON joomla.* TO 'joomlauser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

How to Download Joomla’s Latest Release
