To set up the yum repository for RHEL/CentOS, create the file named /etc/yum.repos.d/nginx.repo with the following contents:
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1
Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “6” or “7”, for 6.x or 7.x versions, respectively.
