CentOS 7 Yum Installation nginx-1.12.0

The Yum in CentOS 7 cannot directly use the Yum install nginx command to install Nginx, because Nginx is not a service that is brought in Yum Library. Figure 1 is the official provision of the approximate installation steps, Figure 2 is the website provided by a number of versions of the Nginx installation package, the following is my own system environment summary of the installation method for your reference:
