How to Fix NGINX error “Failed to read PID from file”
It seems to be a race between systemd and nginx. As if systemd was expecting the PID file to be populated before nginx had the time to create it.
mkdir /etc/systemd/system/nginx.service.d printf "[Service]\nExecStartPost=/bin/sleep 0.1\n" > /etc/systemd/system/nginx.service.d/override.conf systemctl daemon-reload systemctl restart nginx
