ruby on rails - Nginx and Unicorn Basic Config -


i got vm had nginx, unicorn , fresh rails app installed. looked @ nginx config file, , not understand how connects unicorn, since there doesn't seem upstream setting (which tutorial's need).

here config settings:

/home/unicorn/unicorn.conf 

listen "127.0.0.1:8080" worker_processes 2 user "rails" working_directory "/home/rails" pid "/home/unicorn/pids/unicorn.pid" stderr_path "/home/unicorn/log/unicorn.log" stdout_path "/home/unicorn/log/unicorn.log"

/etc/nginx/sites-enabled/default - default file within sites-enabled directory

server {         listen   80;         root /home/rails/public;         server_name _;         index index.htm index.html;          location / {                 try_files $uri/index.html $uri.html $uri @app;         }          location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|mp3|flv|mpeg|avi)$ {                         try_files $uri @app;                 }           location @app {                 proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;                 proxy_set_header host $http_host;                 proxy_redirect off;                 proxy_pass http://app_server;     }  }

the server seems defining location @app, , passing requests http://app_server ... not sure obtain app_server ... upstream defined elsewhere?

fore more info, article has exact same set vps. https://www.digitalocean.com/community/articles/how-to-1-click-install-ruby-on-rails-on-ubuntu-12-10-with-digitalocean

normally app_server defined in file upstream. example - on debian system have location set similar yours pointing upstream called www

in /etc/nginx/sites-enabled directory have file called upstream_www_app following content

upstream www {   server localhost:24910 fail_timeout=0 weight=5; }

24910 port defined in applications config/unicorn.rb , main nginx.conf includes files in sites-enabled directory.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
