IMPORTANT NOTE: I no longer need to restart the servers(my 3 VPS!) to have the pid file back in the dir /run/nginx.pid
I just typed the command: sudo fuser -k 443 / tcp && service nginx start
solves the problem for 24h, as the pid returns to /run/nginx/ without having to restart the service, and is always uptime, but every day the PID disappears! even though a nginx process is in progress and the server always uptime!
so I can use service nginx start and the pid returns to appear the monit returns the monitor the nginx process and I came back to have control over the commands: service nginx status, service nginx stop etc...
Attention, I do not say that nginx stops working, the sites continue oline, I say that the file: /run/nginx.pid disappears every day, so I can no longer use the nginx related commands, even me enter the command
sudo fuser -k 443/tcp
the absence of the file /run/nginx.pid brings several problems, the worst of them is I can not use the commands, service nginx status, start, stop etc..
========================= I need the nginx pid to work with the monit, the pid is simply disappearing unexpectedly, I have to restart the vps to get it back! every night this is happening! but even if he disappears, he's still running! the online site! but obviously I'm unable to monitor status, restart, stop ... etc ... I need pid! when I try to see the status via terminal I have
Error output on the terminal commandline:
service nginx status

If I restart the machine in force, reboot now (I just do this again), the nginx pid reappears(/run/nginx.pid), and monit returns to monitor the process:
https://i.sstatic.net/lvuA5.jpg
but of course no one may have to restart vps just to do a nginx status or nginx restart because there is no more nginx pid on linux server!
I really appreciate your help.
