Get NGINX to serve .gz compressed asset files with unicorn - deployment

Question

I want activate gzip compression in my nginx and unicorn:
I have this in my rails app in config/unicorn.rb:
working_directory "/home/user/project.com/current"
shared_path = '/home/user/project.com/shared'
pid "#{shared_path}/pids/unicorn.pid"
stderr_path "#{shared_path}/log/unicorn.log"
stdout_path "#{shared_path}/log/unicorn.log"
listen '/tmp/unicorn.project.sock'
worker_processes 2
timeout 30
I have this in my nginx.conf in my rails app:
upstream unicorn {
server unix:/tmp/unicorn.project.sock fail_timeout=0;
}
server {
listen 80 default;
root ~/project.com/current/public;
try_files $uri/index.html $uri #unicorn;
location #unicorn {
proxy_pass http://unicorn;
}
error_page 500 502 503 504 /500.html;
}
How can I enable for this config sth like:
gzip_static on;
expires max;
add_header Cache-Control public;
Thank you!

Answer 1

Add to server { } block in your config:
location ~ ^/(assets)/ {
root /path/to/public;
gzip_static on; # to serve pre-gzipped version
expires max;
add_header Cache-Control public;
}
Checkout Rails guides for additional information.

Answer 2

This is what I have in my nginx.conf for gzip:
gzip on;
gzip_buffers 16 8k;
gzip_comp_level 9;
gzip_http_version 1.0;
gzip_min_length 0;
gzip_types text/plain text/css image/x-icon image/png image/jpg image/jpeg text/js text/php application/javascript application/x-javascript;
gzip_vary on;
gzip_proxied expired no-cache no-store private auth;
gzip_disable "MSIE [1-6]\.";
You can also log the gzip compression:
log_format main
'$remote_addr - $remote_user [$time_local] '
'"$request" $status $bytes_sent '
'"$http_referer" "$http_user_agent" '
'"$gzip_ratio"';
