Adjusting child processes for PHP-FPM (Nginx)

Problem:

The following warning message appears in the logs:

[26-Jul-2012 09:49:59] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 8 idle, and 58 total children  
[26-Jul-2012 09:50:00] WARNING: [pool www] server reached pm.max_children setting (50), consider raising it  
It means that there are not enough PHP-FPM processes.

DigitalOcean does not provide a way to download a snapshot of your droplet locally. You can use rsync to accomplish this instead.

On your local machine, assuming you have added your-server in your SSH config:

rsync -aAXHv --append-verify --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} your-server:/

-a : archive mode (all files, with permissions, etc.)
-A : preserve ACLs/permissions (not included with -a)

	server {
	listen 80;
	listen [::]:80;
	server_name example.com www.example.com subsite.com www.subsite.com another.com www.another.com;
	return 301 https://$host$request_uri;
	}

	server {
	listen 443 ssl http2;
	listen [::]:443 ssl http2;
