I know here are a lot of "similar" Q's, but anyway...

So – I have a nginx.conf with gzip on;. It's a new, clean Linux server, nothing yet done here.

Using curl – I can see gzip enabled:

$ curl -I -H "Accept-Encoding: gzip,deflate" gzip.setevoy.kiev.ua/
HTTP/1.1 200 OK
Server: nginx/1.10.3
Date: Wed, 19 Sep 2018 14:26:40 GMT
Content-Type: text/html
Last-Modified: Wed, 19 Sep 2018 13:56:35 GMT
Connection: keep-alive
ETag: W/"5ba25593-264"
Content-Encoding: gzip

Now – I'm adding simple config conf.d/gzip.setevoy.kiev.ua.conf:

server 

 listen 80;
 server_name gzip.setevoy.kiev.ua;

 root /var/www/etag;
 index index.html;

And now – no gzip enabled:

$ curl -I -H "Accept-Encoding: gzip,deflate" gzip.setevoy.kiev.ua/
HTTP/1.1 200 OK
Server: nginx/1.10.3
Date: Wed, 19 Sep 2018 14:28:00 GMT
Content-Type: text/html
Content-Length: 7
Last-Modified: Wed, 19 Sep 2018 13:58:46 GMT
Connection: keep-alive
ETag: "5ba25616-7"
Accept-Ranges: bytes

Adding gzip on; directly to the conf.d/gzip.setevoy.kiev.ua.conf didn't help. Same if set gzip off; in the nginx.conf and gzip on; to the virtualhost's conf.

What I'm doing wrong here?

P.S. gzip_vary on;, gzip_types * etc., didn't help either.

OK, that was simple - but I wasted a lot of time trying to figure it out. Maybe will be helpful for somebody else.

Everything was good with configs, but let's take a look on to the documentation:

Syntax: gzip_min_length length;
Default: gzip_min_length 20;

And guess what? I tested it with index.html with one word added... Obviously, its size was < 20 bytes so NGINX didn't apply gzip on it.

So I just added gzip_min_length 0; to the nginx.conf - and all works now.
