NGINX: connect() to unix:/var/run/php7.2-fpm.sock failed (2: No such file or directory)

first, as the log, your problem is...

you dont have the sock!the sock (php7.2-fpm----) is made when you start php.

check the location to make the sock.
- go to /etc/php/7.2/fpm/pool.d/ -> www.conf
- you can see the listen = "something something" <-- this is the location address.
- if it is not /var/run/php/php7.2-fpm.sock, replace it.
run php (sudo service php7.2-fpm restart)
check the folder you download sock (var/run/php)
if you get the sock, restart your nginx
if you get error, that means your nginx setting (to find the sock) is wrong.
go to etc -> nginx -> sites-enabled and open default
if fastcgi_pass unix:/run/php/php7.2-fpm.sock; is not, replace them.
save and run it.

finish.

Make sure you have everything properly setup.

sudo apt-get install php7.2-fpmsudo service nginx restartsudo service php7.2-fpm restart

This will generate file /run/php/php7.2-fpm.sock

php sockets nginx ubuntu-server

/var/run/ is probably actually a symlink to /run/

/run/ belongs to root and permissions are 755. php-fpm is running as www-data so can't create a socket in /run/

The solution is to create /run/php/and change ownership to www-data, then change your socket path to /run/php/php-fpm.socket
