我得到了当前安装了两个应用程序的服务器，我需要添加另一个，这是我的配置。
nginx.conf
user www-data 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;
##
# Logging Settings
##
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
##
# Disable unknown domains
##
server {
listen 80 default;
server_name _;
return 444;
}
##
# Virtual Host Configs
##
include /home/ruby/apps/*/shared/config/nginx.conf;
}

我还将 capistrano 添加到项目中

end
end
before 'deploy:finalize_update', 'configure'
after "deploy:update", "deploy:migrate", "deploy:cleanup"
require './config/boot'

部署成功，但当我尝试访问 beta.whotracker.com 或 ip 地址时出现SERVER NOT FOUND错误，而其他应用程序运行正常。错误日志中没有显示任何内容。您能指出我的错误在哪里吗？
答案1
您的共享中似乎有拼写错误nginx.conf。您尝试使用的域是，www.beta.whotracker.com但服务器配置显示www.beta.hotracker.com。
答案2
不是http错误代码。你用的是Chrome浏览器吗？可能是浏览器缓存问题。清除缓存后再试。
答案3
检查您的防火墙和 DNS。
这两个应用程序可以正常工作吗？曾经遇到过 nginx/unicorn 的问题最终发现这是由于防火墙配置错误所致。
