1.1.2. 更新源

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 “5”, “6”, or “7”, for 5.x, 6.x, or 7.x versions, respectively.
