之前进行的操作
yum -y install gcc pcre-devel openssl-devel
之后照着 这个来的

到这一步的时候过不去了
提示是
Restarting nginx (via systemctl): Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.
[FAILED]
查看了一下
nginx.service - SYSV: Nginx is a high-performance web and proxy server.
