Hi,
I just created a brand new fedora box.
I then install nginx by running yum install nginx.
I tried to start nginx with the following commands:
$ systemctl enable nginx
$ systemctl restart nginx
However, I got the following error
Failed to read PID from file /run/nginx.pid: Invalid argument
And nginx is not running properly (going to the public IP address of the box does not return anything.
Does anyone know what I did wrong?

This is a known bug with a workaround.

That pid error is often simply caused by restarting Nginx when it isn’t started in the first place. Though the init script should be smart enough to fall back from restart to start. So I don’t think that’s the real problem here. Check to see that Nginx is running and the port that it is listening on by running: netstat -plunt | grep nginx
On Fedora 20, firewalld is running by default. Have you opened port 80?
If the netstat output shows that it is running, then the firewall is most likely your problem. To open the port, run:
firewall-cmd --permanent --zone=public --add-service=http
systemctl restart firewalld.service
