Introduction
Nginx is an asynchronous framework web server that can also be used as a reverse proxy, load balancer and HTTP cache. The software was created by Igor Sysoev and first publicly released in 2004. The company of the same name was established in 2011 to provide support. Nginx is a free and open source software released under the terms of a BSD-like license.
This article describes how to apt install the latest version of Nginx by adding sources in the Debian system.
You can read this article to install PHP: APT install PHP 7.1 / 7.2 / 7.3 / 7.4 in Debian system
installation
Installation prerequisites:
sudo apt install curl gnupg2 ca-certificates lsb-release
To set up the apt repository for the stable nginx package, run the following command:
echo "deb http://nginx.org/packages/debian` lsb_release -cs` nginx "\ | sudo tee /etc/apt/sources.list.d/nginx.list
If you want to use the mainline nginx package, run the following command instead:
echo "deb http://nginx.org/packages/mainline/debian` lsb_release -cs` nginx "\ | sudo tee /etc/apt/sources.list.d/nginx.list
Next, import the official nginx signing key so that apt can verify the authenticity of the software package:
curl -fsSL https://nginx.org/keys/nginx_signing.key | sudo apt-key add-
Verify that you now have the correct key:
sudo apt-key fingerprint ABF5BD827BD9BF62
The output should contain the complete fingerprint 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62as follows:
pub rsa2048 2011-08-19 [SC] [expires: 2024-06-14] 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62 uid [unknown] nginx signing key <[email protected]></[email protected]>
To install nginx, run the following command:
sudo apt update sudo apt install nginx
common problem
Installation using NGINX official source will find an error in Systemd

problem causes
This is because the PID file was not generated when the NGX was started, making the file unreadable
Solution:
In the /lib/systemd/system/nginx.serviceAdd the following statement to achieve 0.1s wait before executing the executable file
ExecStartPost = / bin / sleep 0.1
Then reload the guardian unit
systemctl daemon-reload
Just restart nginx
service nginx restart
