我是 Ruby on Rails 的初学者,在部署我的 rails 应用程序(使用 nginx + unicorn)时遇到了一些困难。我不知道发生了什么,但这是我在启动 nginx 时在日志文件中遇到的错误类型:
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"
如果你能帮助找出问题,或者至少给我一些跟踪它的建议,那就太好了!非常感谢。
我还发布了 nginx.conf 文件:
user www-data;
worker_processes 4;
pid /var/run/nginx.pid;
events {
worker_connections 768;
multi_accept on;
}
http {
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;

upstream sahitoo {
server unix:/home/kar/www/sahitoo/shared/sockets/unicorn.sock;
}
}
使用 /etc/nginx/sites-enabled/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;

if (-f $document_root/system/maintenance.html) {

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 {
