I am trying since 2 days to deploy on my vps (Ubuntu 12.04 Server (64 bits)) using : ruby (1.9.3-rc1), rails, capistrano, nginx and unicorn.
I also follow railscast tutorial from Ryan Bates showing how to deploy on VPS from scratch.
Actualy the cap deploy:cold command seems to work fine (as all the others) but when i try to go on my url i fall on "We're sorry but something went wront" => The default error page from Rails.
In my production logs i get :

Over and over ...
So here is my configs :
my unicorn.rb :

worker_processes 2
timeout 30
And here is my unicorn_init.sh

I have tried
/etc/init.d/unicorn_avocat-immo start
/etc/init.d/unicorn_avocat-immo stop
I also restarted nginx but nothing seems to work. The website load in less then a sec on the error page and the website is not yet working as it should be in production.
Can anyone help me on that matter ?
Additional informations found in nginx errors.log
2013/05/21 12:23:08 [crit] 19097#0: *16 connect() to unix:/tmp/avocat.sock failed (2: No such file or directory) while connecting to upstream, client: **.***.**.***, server: , request: "GET / HTTP/1.1", upstream: "http://unix:/tmp/avocat.sock:/", host: "**.***.**.***"
