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 [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
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.
