Centos 7 + Nginx + PageSpeed

[Josemar Odia]

Hello,

I'm new to nginx. Forgive me if I'm sending the question in the wrong place.

I performed the compilation and installation of Nginx, following this 
tutorial: 
https://www.linode.com/docs/web-servers/nginx/build-nginx-with-pagespeed-from-source/

At first it seemed to be all right, but when checking the status of 
nginx I have the following problem:

$ sudo systemctl status nginx
● nginx.service - The NGINX HTTP and reverse proxy server
    Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; 
vendor preset: disabled)
   Drop-In: /etc/systemd/system/nginx.service.d
            └─override.conf

exited, status = 0 / SUCCESS)
   Process: 5722 ExecStart = / usr / sbin / nginx (code = exited, status

   Process: 5721 ExecStartPre = / usr / sbin / nginx -t (code = exited, 
status = 0 / SUCCESS)
  Main PID: 5724 (nginx)
    CGroup: /system.slice/nginx.service

            └─5725 nginx: worker process

Could you help me solve it?
