rails nginx puma在/etc/nginx/site中复制上游的"puma“-启用

Question

我已经为本教程设置了服务器(https://coderwall.com/p/ttrhow/deploying-rails-app-using-nginx-puma-and-capistrano-3)

当我使用一个项目时，所有工作都正常，但是当我将另一个项目添加到这个VPS时，我出现了错误[emerg] 20737#0: duplicate upstream "puma" in /etc/nginx/sites-enabled/vsejalreg:1。

我的nginx配置

upstream puma {
  server unix:///home/deployer/apps/vsejalreg/shared/tmp/sockets/vsejalreg-puma.sock;
}

server {
  listen 80;
  server_name wjreg.rubyserv.ru www.wjreg.rubyserv.ru;

  root /home/deployer/apps/vsejalreg/current/public;
  access_log /home/deployer/apps/vsejalreg/current/log/nginx.access.log;
  error_log /home/deployer/apps/vsejalreg/current/log/nginx.error.log info;

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

  try_files $uri/index.html $uri @puma;
  location @puma {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    proxy_pass http://puma;
  }

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

和

upstream puma {
  server unix:///home/deployer/apps/register/shared/tmp/sockets/register-puma.sock;
}

server {
  listen 80;
  server_name ws.rubyserv.ru www.ws.rubyserv.ru;

  root /home/deployer/apps/register/current/public;
  access_log /home/deployer/apps/register/current/log/nginx.access.log;
  error_log /home/deployer/apps/register/current/log/nginx.error.log info;

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

  try_files $uri/index.html $uri @puma;
  location @puma {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    proxy_pass http://puma;
  }

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

当我添加nginx配置一个一个-所有的工作！

如何修复这个包或美洲狮与许多项目无关？

谢谢！

Answer 1

Puma可以使用任何正确配置的项目:)您可以配置命名为上游(上游美洲狮)一次，而不是每个服务器配置。如果每个服务器需要不同的puma实例，只需设置具有不同名称的上游。

upstream puma_vsejalreg {
  server unix://...PATH.../vsejalreg-puma.sock;
}
upstream puma_register {
  server unix://...PATH.../register-puma.sock;
}

Answer 2

请注意，您也需要更改此部分：

location @puma {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    proxy_pass http://puma;
  }

否则，您将遇到诸如- nginx: [emerg] host not found in upstream "puma" in /etc/nginx/sites-enabled/furnitureapp:25这样的错误。

所以，如果你把上游重命名为

upstream puma_register

您还需要将proxy_pass重命名为

location @puma {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    proxy_pass http://puma_register; <------ Change here
  }
