Nginx

Installation

Debian

1. Install the prerequisites:

   sudo apt install curl gnupg2 ca-certificates lsb-release debian-archive-keyring
   

2. Import an official nginx signing key so apt could verify the packages authenticity. Fetch the key:

   curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
   | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
   

3. To set up the apt repository for stable nginx packages, run the following command:

   echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
   http://nginx.org/packages/debian `lsb_release -cs` nginx" \
   | sudo tee /etc/apt/sources.list.d/nginx.list
   

4. Install nginx, run the following commands:

   sudo apt update
   sudo apt install nginx
   

5. Enable nginx. Auto restart on boot.

   systemctl enable nginx
   

You’re on nginx 1.24.0, which is the version Ubuntu 24.04 (Noble) ships by default. To get a newer version, you need to switch to the official nginx.org repository — Ubuntu’s repos won’t move past 1.24.0. Latest versions available

Stable: 1.30.4 (recommended for production)
Mainline: 1.31.4 (newer features, more frequent updates)

Step-by-step upgrade

1. Backup your config bash

sudo cp -r /etc/nginx /etc/nginx.backup.$(date +%Y%m%d)

1. Install prerequisites bash

sudo apt update sudo apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring

1. Add the official nginx signing key bash

curl https://nginx.org/keys/nginx_signing.key	gpg –dearmor \
	sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null

1. Add the nginx.org repository For stable (recommended): bash

echo “deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg]
https://nginx.org/packages/ubuntu $(lsb_release -cs) nginx”
| sudo tee /etc/apt/sources.list.d/nginx.list

For mainline (latest features): bash

echo “deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg]
https://nginx.org/packages/mainline/ubuntu $(lsb_release -cs) nginx”
| sudo tee /etc/apt/sources.list.d/nginx.list

1. Pin nginx.org packages higher than Ubuntu’s bash

echo -e “Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n”
| sudo tee /etc/apt/preferences.d/99nginx

1. Update and upgrade nginx bash

sudo apt update sudo apt install nginx
