This article explains installing and using Backdrop CMS on Ubuntu Linux with Apache support.
Backdrop CMS is a free, open-source content management system for small to mid-size businesses and non-profit organizations looking to publish their content easily and quickly with a customize-able platform.
Besides building great websites and blogs, Backdrop has integrated security for granular access control and speed. It’s similar to Drupal but includes numerous usability improvements and new features unavailable to users.
When you’re ready to get Backdrop working, continue with the steps below:
How to install Backdrop CMS on Ubuntu Linux with Apache Support
As mentioned above, Backdrop CMS is a free, open-source content management system for small to mid-size businesses and non-profit organizations looking to publish their content easily and quickly with a customized-able platform.
Below is how to install it on Ubuntu Linux.
Install Apache2
Apache2 HTTP Server is the most popular web server in use. Install it since Backdrop needs it.
To install Apache2 HTTP on the Ubuntu server, run the commands below.
sudo apt update sudo apt install apache2
After installing Apache2, the commands below can be used to stop, start and enable the Apache2 service to always start up with the server boots.
sudo systemctl stop apache2.service sudo systemctl start apache2.service sudo systemctl enable apache2.service
To test the Apache2 setup, open your browser and browse to the server hostname or IP address, and you should see the Apache2 default test page as shown below. When you see that, then Apache2 is working as expected.
http://localhost

Install MariaDB
MariaDB database server is a great place to start when looking at open-source database servers for Magento. To install MariaDB run the commands below.
sudo apt-get install mariadb-server mariadb-client
After installing MariaDB, the commands below can stop, start and enable the MariaDB service to start up 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 17.10 and 18.04 LTS
sudo systemctl stop mariadb.service sudo systemctl start mariadb.service sudo systemctl enable mariadb.service
After that, run the commands below to secure the MariaDB server by creating a root password and disallowing remote root access.
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 the password
- Re-enter new password: Repeat password
- Remove anonymous users? [Y/n]: Y
- Disallow root login remotely? [Y/n]: Y
- Remove the test database and access it. [Y/n]: Y
- Reload privilege tables now? [Y/n]: Y
Type the commands below to log on to the MariaDB server to test if MariaDB is installed.
sudo mysql -u root -p
Then type the password you created above to sign on. If successful, you should see MariaDB welcome message.

Install PHP 7.2 and Related Modules
PHP 7.2 isn’t available on Ubuntu’s default repositories. 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 7.2
sudo apt-get install software-properties-common sudo add-apt-repository ppa:ondrej/php
Then update and upgrade to PHP 7.2
sudo apt update
Next, run the commands below to install PHP 7.2 and related modules.
sudo apt install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-mbstring php7.2-xmlrpc php7.2-soap 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 the PHP default config file for Apache2.
sudo nano /etc/php/7.2/apache2/php.ini
Then save the changes on the following lines below in the file. The value below is an ideal setting to apply in your environment.
file_uploads = On allow_url_fopen = On memory_limit = 256M upload_max_filesize = 100M max_execution_time = 360 date.timezone = America/Chicago
After making the change above, please save the file and close it.
After installing PHP and related modules, you must restart Apache2 to reload PHP configurations.
To restart Apache2, run the commands below
sudo systemctl restart apache2.service
To test PHP 7.2 settings with Apache2, create a phpinfo.php file in the Apache2 root directory by running the commands below
sudo nano /var/www/html/phpinfo.php
Then type the content below and save the file.
<?php phpinfo( ); ?>
Save the file. Then browse to your server hostname followed by /phpinfo.php
http://localhost/phpinfo.php
You should see the PHP default test page.

Create Backdrop Database
Once you’ve installed all the packages that Backdrop can function, continue below to start configuring the servers.
First, run the commands below to create a blank Backdrop database.
To log on to the MariaDB database server, run the commands below.
sudo mysql -u root -p
Then create a database called Backdrop.
CREATE DATABASE backdrop;
Create a database user called Backdrop used with a new password
CREATE USER 'backdropuser'@'localhost' IDENTIFIED BY 'new_password_here';
Then grant the user full access to the database.
GRANT ALL ON backdrop.* TO 'backdropuser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;
Finally, save your changes and exit.
FLUSH PRIVILEGES; EXIT;
Download and Install Backdrop
Run the commands below to download Backdrop latest. Then create a root directory for Backdrop and unzip the content there.
cd /tmp && wget https://github.com/backdrop/backdrop/releases/download/1.9.2/backdrop.zip unzip backdrop.zip sudo mv backdrop /var/www/html/backdrop
Next, run the commands below to change the root folder permissions.
sudo chown -R www-data:www-data /var/www/html/backdrop/ sudo chmod -R 755 /var/www/html/backdrop/
Configure Apache2 Backdrop Site
Finally, configure the Apache2 configuration file for Backdrop. This file will control how users access Backdrop content. Run the commands below to create a new configuration file called Backdrop.conf.
sudo nano /etc/apache2/sites-available/backdrop.conf
Then copy and paste the content below into the file and save it. Replace the highlighted line with your domain name and directory root location.
<VirtualHost *:80> ServerAdmin admin@example.com DocumentRoot /var/www/html/backdrop/ ServerName example.com ServerAlias www.example.com <Directory /var/www/html/backdrop/> Options FollowSymlinks AllowOverride All Require all granted </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost>
Save the file and exit.
After configuring the VirtualHost above, please enable it by running the commands below.
Enable the Backdrop Site and Rewrite the Module
After configuring the VirtualHost above, please enable it by running the commands below, then restart the Apache2 server.
sudo a2ensite backdrop.conf sudo a2enmod rewrite sudo systemctl restart apache2.service
Install Let’s Encrypt Client
You should first install its client to get Let’s Encrypt free SSL/TLS certificates on your Ubuntu machine. The client helps automate the process for you. To install it, run the commands below.
sudo apt-get install python-certbot-apache
If python-certbot-Nginx isn’t installed, you may have to add its PPA repository and install the package.
sudo add-apt-repository ppa:certbot/certbot sudo apt-get update sudo apt-get install python-certbot-apache
Obtaining your free SSL/TLS Certificates
After installing the Let’s Encrypt Certbot client module for Apache2, run the commands below to obtain your free Let’s Encrypt SSL/TLS certificate in the domain specified. Make sure to replace example.com with your domain.
sudo certbot --apache -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 Apache2 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
agree in order to register with the ACME server at

This is how easy it is to obtain your free SSL/TLS certificate for your Apache2-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 automatically be added to your Apache2 Backdrop configuration file by Let’s Encrypt certbot. After that, your Backdrop site is ready to be used over HTTPS.
<VirtualHost *:80> ServerAdmin admin@example.com DocumentRoot /var/www/html/backdrop/ ServerName example.com ServerAlias www.example.com <Directory /var/www/html/backdrop/> Options FollowSymlinks AllowOverride All Require all granted </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined RewriteEngine on RewriteCond %{SERVER_NAME} =example.com [OR] RewriteCond %{SERVER_NAME} =www.example.com RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent] </VirtualHost>
A new configuration file for the domain should also be created named /etc/apache2/sites-available/example.com-le-SSL.conf. This Apache2 SSL module configuration file should contain the defined certificate definitions.
<IfModule mod_ssl.c> <VirtualHost *:443> ServerAdmin admin@example.com DocumentRoot /var/www/html/backdrop/ ServerName example.com ServerAlias www.example.com <Directory /var/www/html/backdrop/> Options FollowSymlinks AllowOverride All Require all granted </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem Include /etc/letsencrypt/options-ssl-apache.conf </VirtualHost> </IfModule>
You’ll have to renew the certificates manually. You’ll get an email reminder to reset when the certificates are about to expire. To test the renewal process, run the commands below.
sudo certbot renew --dry-run
To set up 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
After that, open your browser and browse your domain name to launch the Backdrop configuration wizard.
You should see the Backdrop setup wizard complete. Please follow the wizard carefully.
