Nginx enable gzip - nginx

Question

I want enable the gzip compression on my nginx server. The nginx.conf file is here:
http {
# Enable Gzip
server {
location ~* \.(?:ico|woff|css|js|gif|jpe?g|png)$ {
expires 30d;
add_header Pragma public;
add_header Cache-Control "public";
}
location /api {
try_files $uri $uri/ /api/index.php;
}
location / { ##merge
gzip on;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_min_length 1100;
gzip_buffers 4 8k;
gzip_proxied any;
gzip_types
# text/html is always compressed by HttpGzipModule
text/css
text/javascript
text/xml
text/plain
text/x-component
application/javascript
application/json
application/xml
application/rss+xml
font/truetype
font/opentype
application/vnd.ms-fontobject
image/svg+xml;
gzip_static on;
gzip_proxied expired no-cache no-store private auth;
gzip_disable "MSIE [1-6]\.";
gzip_vary on;
try_files $uri $uri/ /index.php?q=$uri&$args;
}
location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" { add_header "" ""; }
location ~ "^/ngx_pagespeed_static/" { }
location ~ "^/ngx_pagespeed_beacon" { }
}
}
Unfortunately the gzip compression not working, Google Pagespeed and Gtmetrix not detect this.
Where can I place the gzip conf?
In The http{} server{} or location{} tag?
I already tried in the http and in the location tags too

You can put the gzip configuration anywhere, but if you want to apply it to all websites / files it is best to put it in the http section - this will then be the default for all server and location blocks. I would also "shorten" / change your config to the following:
http {
gzip on;
gzip_min_length 500;
gzip_proxied any;
gzip_comp_level 4;
gzip_types text/css text/javascript text/xml text/plain text/x-component application/javascript application/json application/xml application/rss+xml font/truetype font/opentype application/vnd.ms-fontobject image/svg+xml;
gzip_vary on;
gzip_disable "msie6";
... here come your server blocks / rest of your config
}
I use that configuration and it works fine for me - you can also test it in your browser first (for example with Firebug) before testing it with external services.
Using gzip_static only makes sense if you actually generate gzipped files for Nginx (as filename + .gz), so this has nothing to do with enabling gzip and should only be a possible second step.
