Installation on Linux

---

nginx can be installed differently, depending on the operating system.
For Linux, nginx packages from nginx.org can be used.

Installation instructions

Before you install nginx for the first time on a new machine, you need to set up the nginx packages repository. Afterward, you can install and update nginx from the repository.

RHEL/CentOS

Install the prerequisites:

sudo yum install yum-utils

To set up the yum repository, create the file named /etc/yum.repos.d/nginx.repo with the following contents:

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

By default, the repository for stable nginx packages is used. If you would like to use mainline nginx packages, run the following command:

sudo yum-config-manager --enable nginx-mainline

To install nginx, run the following command:

sudo yum install nginx

When prompted to accept the GPG key, verify that the fingerprint matches 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62, and if so, accept it.

Ubuntu

Install the prerequisites:

sudo apt install curl gnupg2 ca-certificates lsb-release

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

echo "deb http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list

If you would like to use mainline nginx packages, run the following command instead:

echo "deb http://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list

Next, import an official nginx signing key so apt could verify the packages authenticity:

curl -fsSL https://nginx.org/keys/nginx_signing.key | sudo apt-key add -

Verify that you now have the proper key:

sudo apt-key fingerprint ABF5BD827BD9BF62

The output should contain the full fingerprint 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62 as 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 <signing-key@nginx.com>

To install nginx, run the following commands:

sudo apt update
sudo apt install nginx
