Create a separate custom conf file within /etc/nginx/ folder
mkdir /etc/nginx/global
cd /etc/nginx/global
sudo touch buffers.conf
sudo touch timeouts.conf
sudo touch file_handle_cache.conf
sudo nano buffers.conf

## NGINX.CONF BUFFER DIRECTIVES
######
# BUFFERS
client_body_buffer_sixe 10k;
client_header_buffer_size 1k;
clidnt_max_body_size 8m;

# FILE HANDLE CACHE

Nginx will keep open 1500 files for 30 seconds. This excludes any file that has not been accessed for 30 sec; and only files that have been accessed in this timeframe
sudo nano timeouts.conf

## NGINX.CONF TIMEOUTS DIRECTIVES
######
# TIMEOUTS
client_header_timeout 3m;
client_body_timeout 3m;
keepalive_timeout 100;
keepalive_requests 1000;
send_timeout 3m;
Navigate one folder up (to /etc/nginx)
sudo nano nginx.conf
Add a heading in the nginx.conf under section #Virtual Hosts Configs (under the line: include /etc/nginx/sites-enabled/*;). This is located in http context. (Tutor also says that this is the end of the file - however - fit the code before the final curly bracket)
##
# Buffers Timeouts File Handle Cache
##
*(use 'include directive'--> syntax for this is: include <path to the file>
include global/buffers.conf;
include global/timeouts.conf;
# include global/file_handle_cache.conf
*(comment out the file_handle_cache.conf- it will be uncommented once server is running. For it to work proprely it needs a stable asset environment.)
Save changes, exit nano
sudo nginx -t
sudo systemctl reload nginx
