If this is the first time you are installing a package from the EPEL repository, yum may prompt you to import the EPEL GPG key:

Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
Importing GPG key 0x352C64E5:
Userid     : "Fedora EPEL (7) <[email protected]>"
Fingerprint: 91e9 7d7c 4a5e 96f1 7f3e 888f 6a2f aea2 352c 64e5
Package    : epel-release-7-9.noarch (@extras)
From       : /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
Is this ok [y/N]:

If that’s the case, type y and hit Enter.

• Once the installation is complete, enable and start the Nginx service with:

 
sudo systemctl enable nginx
sudo systemctl start nginx

Check the status of the Nginx service with the following command:

 
sudo systemctl status nginx

The output should look something like this:

• If your server is protected by a firewall you need to open both HTTP (80) and HTTPS (443) ports.Use the following commands to open the necessary ports:
  

  sudo firewall-cmd –permanent –zone=public –add-service=http
  sudo firewall-cmd –permanent –zone=public –add-service=https
  sudo firewall-cmd –reload

• To verify your Nginx installation, open http://YOUR_IP in your browser of choice, and you will see the default Nginx welcome page as shown in the image below:
