This guide has been created to help users running Ubuntu 22.04 or 20.04 or 18.04 server to install Nginx web server and configure PHP-FPM (FastCGI Process Manager). Nginx is a high performance web server that’s free to use. Nginx is designed for speed and scalability with capabilities of reverse proxy and load balancing to a number of backend servers both with HTTP, TCP and UDP protocols. This website is powered by WordPress and Nginx and the performance is really good. Nginx has small memory footprint as compared to Apache, handling same number of concurrent connections.
Features of Nginx Web Server
- Content Cache – Cache static and dynamic content
- Load Balancing – HTTP, TCP, and UDP load balancing with Layer 7 request routing using URI, cookie, args, and more.
- Reverse proxy multiple protocols: HTTP, gRPC, memcached, PHP‑FPM, SCGI, uwsgi
- Handle hundreds of thousands of clients simultaneously
- Stream HTTP video: FLV, HDS, HLS, MP4
- HTTP/2 gateway with HTTP/2 server push support
- Dual‑stack RSA/ECC SSL/TLS offload
- Monitoring plugins: AppDynamics, Datadog, Dynatrace plug‑ins
Update Ubuntu
Before you begin, you should have a running Ubuntu server that has been updated and upgraded to the latest available packages.
sudo apt update
sudo apt upgradeInstall Nginx Web Server
After the system is updated, proceed to install Nginx package on Ubuntu 22.04|20.04 Linux system:
sudo apt install nginxThe service should be started automatically after installation.
$ systemctl status nginx

sudo systemctl disable --now apache2
sudo systemctl restart nginxUFW firewall can be configured to allow port 80:
sudo ufw allow proto tcp from any to any port 80,443Install PHP-FPM
If you’re planning on using PHP with Nginx, consider installing PHP-FPM package.
sudo apt update
sudo apt install php php-cli php-fpm php-json php-mysql php-zip php-gd php-mbstring php-curl php-xml php-pear php-bcmathPHP-FPM has the service that should be running.
