We can disable access logging in two ways one is Disabling All Access Logging and another one is Disabling access logging at particular request

Option 1:

We can set disabling all access logs although this is not recommended,

Find NGINX conf file

# whereis nginx


nginx: /etc/nginx /usr/local/sbin/nginx /usr/local/nginx

most probably configure file is located in /etc/nginx/nginx.conf

Open your nginx.conf file and add a line,
 
# vim /etc/nginx/nginx.conf


access_log off;

Save a file and restart your nginx server,
 
# /etc/init.d/nginx restart

Option 2:

If would you like to disabling acess logging of particular requests, for example


location = /mypage {

   #.....

   access_log off;

}

check your nginx whether is working?
 
# ps aux | grep nginx
