How to enable gzip on nginx

Here you have a super easy guide to enable gzip on nginx

1. Make Sure Gzip module is installed with nginx

2>&1 nginx -V | tr -- - '\n' | grep _module | grep gzip

The expected output should be: http_gzip_static_module

2. Update the host configuration file under the server block entry

gzip on;
gzip_disable "msie6";

gzip_comp_level 6;
gzip_min_length 1100;
gzip_buffers 16 8k;
gzip_proxied any;
gzip_types
    text/plain
    text/css
    text/js
    text/xml
    text/javascript
    application/javascript
    application/x-javascript
    application/json
    application/xml
    application/rss+xml
    image/svg+xml/javascript;

3. Reload the nginx configuration

service nginx reload;

4. Testing

curl -H "Accept-Encoding: gzip" -I https://smartit.ninja/

And the expected output: 

HTTP/1.1 200 OK
Server: nginx/1.15.9
