2013/04/14 00:31:42 [error] 14469#0: *1 connect() to unix:/home/user/www/sahitoo/shared/sockets/unicorn.sock 
**failed (111: Connection refused)** while connecting to upstream, client: XX.XXX.XX.XX, server: myapp.com, 
request: "GET/HTTP/1.1", upstream: "http://unix:/home/user/www/sahitoo/shared/sockets/unicorn.sock:/", 
host: "www.XXXXX.com"

如果你能帮忙找出问题，或至少给我一些建议跟踪它，这将是非常好的！非常感谢。

我也交nginx.conf文件：

user www-data; 
worker_processes 4; 
pid /var/run/nginx.pid; 

events { 
    worker_connections 768; 
    multi_accept on; 
}

    sendfile on; 
    tcp_nopush on; 
    tcp_nodelay on; 
    keepalive_timeout 65; 
    types_hash_max_size 2048; 

    include /etc/nginx/mime.types; 
    default_type application/octet-stream; 

    access_log /var/log/nginx/access.log; 
    error_log /var/log/nginx/error.log; 

    gzip on; 
    gzip_disable "msie6"; 

    gzip_http_version 1.1; 
    gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; 

    ## 
    # Virtual Host Configs 
    ## 

    include /etc/nginx/conf.d/*.conf; 
    include /etc/nginx/sites-enabled/*; 

    upstream sahitoo { 
    server unix:/home/kar/www/sahitoo/shared/sockets/unicorn.sock; 
    } 
}

随着的/ etc/nginx的/启用的站点 -/sahitoo文件：

server { 
    listen 80; 
    server_name myapp.com; 

    access_log /var/log/nginx/sahitoo.access.log; 
    error_log /var/log/nginx/sahitoo.error.log; 

    root /www/sahitoo/public; 

     # direct to maintenance if this file exists 
     if (-f $document_root/system/maintenance.html) { 
     rewrite ^(.*)$ /system/maintenance.html last; 
    break; 
    } 

    location/{ 
    proxy_redirect   http://sahitoo/    /; 
    proxy_set_header  Host               $host; 
    proxy_set_header  X-Real-IP              $remote_addr; 
proxy_set_header X-Forwarded-For            $proxy_add_x_forwarded_for; 

    # If the file exists as a static file serve it directly 
    if (-f $request_filename) { 
     break; 
    } 

    if (!-f $request_filename) { 
     proxy_pass http://sahitoo; 
     break; 
    } 
    } 

    error_page 500 502 503 504 /500.html; 
    location = /500.html { 
    root /home/kar/www/sahitoo/public; 
    } 
}

似乎像独角兽没有运行。 – Intrepidd

感谢Intrepidd，独角兽也给我错误，也许确实是源头问题...... Je peux te contacter enprivé？ –

我建议看看这个工作示例nginx.conf：

upstream unicorn-your_app { 
    server unix:/tmp/unicorn.your_app.sock fail_timeout=0; 
} 

server { 
    listen 80; 
    server_name myapp.com; 
    root /www/sahitoo/current/public; 

    location ^~ /assets/ { 
    gzip_static on; 
    expires max; 
    add_header Cache-Control public; 
    } 

    try_files $uri/index.html $uri @unicorn-yourapp; 
    location @unicorn-yourapp { 
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    proxy_set_header Host $http_host; 
    proxy_redirect off; 
    proxy_pass http://unicorn-your_app; 
    } 

    error_page 500 502 503 504 /500.html; 
    client_max_body_size 4G; 
    keepalive_timeout 10; 
}

正如您所看到的，有一些不同之处：

upstram block;
根指向your_dir/current/public;
try_files例程;
location @unicorn-yourapp;

如果您想对该主题有更深入的了解，有非常好的Railscast。

嗨，谢谢，所以我用这个例子替换当前的nginx.conf？ –

我认为你应该看看命名约定，然后替换你的/ etc/nginx/sites-enabled/sahitoo文件。我的例子是引导你通过配置过程，所以再次检查输入错误的目录名称，然后替换它。 –

如果你是在一个不同的用户，可能根本运行红宝石，它不会对当前用户的任何特权就会发生这种情况，你确定你是从

得到结果“红宝石-v”或'rails -v'

。
