Instale o nginx 1.8 no Centos 7

Question

Estou tentando instalar o nginx 1.8 no Centos 7. Eu tentei os seguintes passos:

1. Instale o repositório nginx no link

   wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
   rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm
   

2. Instalar o Nginx

   yum install nginx
   

3. Iniciar o Nginx:

   sudo systemctl start nginx
   

Mas nada acontece; O nginx não inicia. As mesmas etapas corretas funcionam no Centos 6 sem problemas.

Aqui está a saída de systemctl status nginx :
