gzip compression not working with nginx and centos 7

Question

I want to enable gzip compression on my virtual host with nginx. My control panel is Plesk17 but I have access to server root. I found the vhost nginx config file in this dir:

/etc/nginx/plesk.conf.d/vhosts

and add this codes in server block to enable gzip:

gzip on;
gzip_disable msie6;
gzip_proxied any;
gzip_buffers 16 8k;
gzip_types    text/plain application/javascript application/x-javascript text/javascript text/xml text/css;
gzip_vary on;

After all and restarting the nginx, when I check the gzip status, it looks disabled!

For your information, I also have this comments at the top of my config file:

#ATTENTION!
#
#DO NOT MODIFY THIS FILE BECAUSE IT WAS GENERATED AUTOMATICALLY,
#SO ALL YOUR CHANGES WILL BE LOST THE NEXT TIME THE FILE IS GENERATED.

What's wrong? how can I enable the gzip?

Answer 1

To enable gzip compression for particular domain open Domains > example.com > Apache & nginx Settings > Additional nginx directives and add directives to this section.
If you want to enable it server-wide just create new file /etc/nginx/conf.d/gzip.conf add content there and restart nginx.
