yum install nginx

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.

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.
