Table of Contents
1. Login via SSH and Update the Packages
Make sure your package list and the OS packages are up to date by running the following commands:
sudo apt-get update sudo apt-get upgrade
2. Download Nginx Server
To install the latest Nginx version from the official Nginx repository, edit the ‘/etc/apt/sources.list’ file:
sudo vi /etc/apt/sources.list
Add the following lines:
deb http://nginx.org/packages/ubuntu/ xenial nginx deb-src http://nginx.org/packages/ubuntu/ xenial nginx
3. Install MySQL
sudo apt-get install mysql-server
4. Stop and remove Apache service:
sudo service apache2 stop sudo apt-get remove apache2
5. Install Nginx on your virtual server
sudo apt-get update sudo apt-get install nginx
6. Configure Nginx to start on boot
sudo update-rc.d -f nginx defaults
7. Install PHP and PHP modules required by Backdrop CMS
sudo apt-get install php7.0 php7.0-cli php7.0-fpm php7.0-mbstring php7.0-mysql php7.0-gd php7.0-mcrypt php7.0-imap uw-mailutils libgd-tools libmcrypt-dev mcrypt php-pear libgd-dev
Then, start with the Backdrop CMS installation procedure. Get the latest version of Backdrop CMS available at their official website to a directory of your virtual server and extract it using the following commands:
sudo apt-get install wget unzip cd /opt/ wget https://github.com/backdrop/backdrop/releases/download/1.4.3/backdrop.zip unzip backdrop.zip mkdir -p /var/www/html mv backdrop /var/www/html
8. Configure Nginx
Create a new Nginx configuration file and add the following virtual block for your domain name:
vi /etc/nginx/conf.d/your-domain.com.conf
Add the following lines:
server {
listen 80;
server_name your-domain.com;
root /var/www/backdrop/;
index index.php;
access_log /var/log/nginx/your-domain.com-access.log;
error_log /var/log/nginx/your-domain.com-error.log;
charset en_us.UTF-8;
location / {
error_page 404 = @backdrop; }
location @backdrop { rewrite ^(.*)$ /index.php?q=$1 last; }
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
Do not forget to replace your-domain.com with your actual domain name. Then, delete the ‘default’ Nginx configuration file:
rm /etc/nginx/conf.d/default.conf
Open the ‘/etc/php/7.0/fpm/pool.d/www.conf’ file and change the ‘listen’ variable:
change:
listen = /run/php/php7.0-fpm.sock
to
listen = 127.0.0.1:9000;
Locate the PHP configuration file:
# php -i | grep -i php.ini Configuration File (php.ini) Path => /etc/php/7.0/cli Loaded Configuration File => /etc/php/7.0/cli/php.ini
Edit the ‘/etc/php/7.0/cli/php.ini’ configuration file:
vi /etc/php/7.0/cli/php.ini
Add/modify the following settings:
max_execution_time = 300 max_input_time = 300 memory_limit = 128M post_max_size = 32M upload_max_filesize = 32M
The web server user (www-data) needs to be able to write to files and directories inside the ‘/var/www/backdrop’ directory, so it can easily be accomplished by executing the following command:
sudo chown www-data:www-data -R /var/www/backdrop/
9. Test the Nginx configuration
# nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful
If test is successful, restart php7.0-fpm and Nginx services for the changes to take effect:
sudo service php7.0-fpm restart sudo service nginx restart
Backdrop CMS requires a database to work as this is where data is saved, so create a new MySQL database:
mysql -u root -p mysql> create database backdropdb; mysql> GRANT ALL PRIVILEGES ON backdropdb.* TO 'backdropuser'@'localhost' IDENTIFIED BY 'Y0UR-PASSW0RD'; mysql> flush privileges; mysql> quit
Open http://your-domain.com/ using your favorite web browser and follow the easy instructions. Once installed, log in to the administrator back-end and configure Backdrop CMS according to your needs.
That is it. The Backdrop CMS installation is now complete.
