我已经使用capistrano在Ryan Bates 335教程之后部署了我的rails应用程序。
当我转到我的网址时，我收到404错误，我不知道为什么。即使我运行sudo service nginx stop，它也不会停止服务器。
现在我有以下设置
Linode服务器：
我的nginx.conf位于/opt/nginx/conf/nginx.conf
user www-data;
worker_processes 4;
pid /var/run/nginx.pid;
worker_rlimit_nofile 8192;
events {
worker_connections 8000;
}
http {

}
在我的rails app / home / aurelien / apps / my-app / current / config我有另外一个nginx.conf文件，包含以下内容
server {
listen 80;
server_name XXX.XXX.XX.XX;
root /home/aurelien/apps/my-app/current/public;
passenger_enabled on;
location ^~ /assets/ {
gzip_static on;

add_header Cache-Control public;
}
error_page 500 422 404 /500.html;
}
我真的不知道我做错了什么，我不知道如何调试。我真的希望尽快在线获取我的rails应用程序。
当我运行命令cap deploy:update时，它并不总是更新current目录中的文件。我不知道为什么，即使github上的文件是最新的。这是我的deploy.rb以供参考：
