After the first reload: "nginx: [error] open() "/var/run/nginx.pid" failed (2: No such file or directory)"

Using Salt I applied states that install and run NGINX (1.14.0-0ubuntu1.7) as a service. Service's status is active but systemctl reload nginx keeps failing thus an updated config cannot be applied.

Full logs:

systemd[1]: nginx.service: Can't open PID file /run/nginx.pid (yet?) after reload: No such file or directory
systemd[1]: Reloaded A high performance web server and a reverse proxy server.

Solution

  • I solved this by restarting nginx instead of reloading:

    service nginx restart
service nginx status

    after this, also a reload worked fine and the pid number is stored in

     /var/run/nginx.pid
