连接到上游时，连接(111:连接拒绝)连接(/var/run/unicorn.sock失败(111:连接)

Question

我在Rails上关注Ruby一个应用程序点击部署。数据库做得很好，即使我检查了Rails控制台，所有工作正常

017/02/26 15:34:17 [error] 18564#0: *31 connect() to unix:/var/run/unicorn.sock failed (111: Connection refused) while connecting to upstream, client: 121.52.156.57, server: _, request: "GET / HTTP/1.1", upstream: "http://unix:/var/run/unicorn.sock:/", host: "188.166.157.124"

uncorn.conf是

listen "unix:/var/run/unicorn.sock"
worker_processes 4
user "rails"
working_directory "/home/rails/company_startup"
pid "/var/run/unicorn.pid"
stderr_path "/var/log/unicorn/unicorn.log"
stdout_path "/var/log/unicorn/unicorn.log"

nginx是

upstream app_server {
server unix:/var/run/unicorn.sock fail_timeout=0;
}
server {
listen   80;
root /home/rails/nehbor-webserver/public;
server_name _;
index index.htm index.html;
client_max_body_size 1M;
location / {
        try_files $uri/index.html $uri.html $uri @app;
}
location ~* ^.+.(jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mp3|flv|mpeg|avi)$ {
                try_files $uri @app;
        }
 location @app {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://app_server;
}
}

Answer 1

根据独角兽文档，我认为您应该从配置中的listen方法中删除unix零件，然后将其更改为listen "/var/run/unicorn.sock"。

listen 3000 # listen to port 3000 on all TCP interfaces
listen "127.0.0.1:3000"  # listen to port 3000 on the loopback interface
listen "/path/to/.unicorn.sock" # listen on the given Unix domain socket
listen "[::1]:3000" # listen to port 3000 on the IPv6 loopback interface

Answer 2

在简短的Nginx中试图重新指导到您的应用程序，但不能。在基本配置的事物和结构之外，我认为最常见的问题与：

• 端口
• 插座
• 对我（使用AWS EC2），我正在使用一个通过DNS Registar上的CNAME记录链接的域。IP更改了更改域服务器名称，我的记录没有更新。我刚将它从cname记录名称更改为我的新弹性域名。
