Nginx 502 Bad Gateway – 111：连接被拒绝，端口没有被侦听

我知道还有很多其他类似的问题，但是我觉得我已经有了这些问题的解决scheme。

我有3个站点在VirtualBox Ubuntu 12.04.4 LTS服务器上本地运行，我使用nginx和php-fpm。

它们被configuration为在端口9001 – > 9003上运行：

server:/etc/php5/fpm/pool.d$ grep 900 * my-app-deploy.conf:listen = 127.0.0.1:9002 my-app-dev.conf:listen = 127.0.0.1:9001 my-web.conf:listen = 127.0.0.1:9003 server:/etc/nginx/conf.d$ grep 900 * my-app-deploy.conf: fastcgi_pass 127.0.0.1:9002; my-app-dev.conf: fastcgi_pass 127.0.0.1:9001; my-app-web.conf: fastcgi_pass 127.0.0.1:9003; 

我已经成功地重启了php-fpm和nginx ：

• Iptables在CentOS 7上封锁了WildFly10
• 为什么我不能访问端口8333上的VMware Server？
• IPTables – 更改传出和传入数据包的端口
• 如何将临时端口映射到一个pid？
• ssh到一个端口

 server:$ sudo service nginx restart * Restarting nginx nginx ...done. server:$ sudo service php5-fpm restart * Restarting PHP5 FastCGI Process Manager php5-fpm ...done. 

但是，如果我看看哪些端口正在听，我只看到9002和9003 ：

 server:$ sudo lsof -i | grep 900 php5-fpm 1020 root 7u IPv4 8557 0t0 TCP localhost:9002 (LISTEN) php5-fpm 1020 root 8u IPv4 8558 0t0 TCP localhost:9003 (LISTEN) php5-fpm 1021 www-data 0u IPv4 8557 0t0 TCP localhost:9002 (LISTEN) php5-fpm 1022 www-data 0u IPv4 8557 0t0 TCP localhost:9002 (LISTEN) php5-fpm 1023 www-data 0u IPv4 8557 0t0 TCP localhost:9002 (LISTEN) php5-fpm 1024 www-data 0u IPv4 8557 0t0 TCP localhost:9002 (LISTEN) php5-fpm 1025 www-data 0u IPv4 8558 0t0 TCP localhost:9003 (LISTEN) php5-fpm 1026 www-data 0u IPv4 8558 0t0 TCP localhost:9003 (LISTEN) php5-fpm 1027 www-data 0u IPv4 8558 0t0 TCP localhost:9003 (LISTEN) php5-fpm 1028 www-data 0u IPv4 8558 0t0 TCP localhost:9003 (LISTEN) 

我从nginx得到以下错误：

 server:~/vhosts/my-app/logs$ tail -n 1 nginx/error.log 2014/06/20 11:07:36 [error] 2434#0: *4 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.0.10, server: my.app.dev, request: "GET /api/test.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9001", host: "my.app.dev" 

我希望我错过了一些非常基本的东西，但是当我在9002上添加网站时，我不记得除了将新的端口号添加到两个conf文件

更新站点根目录实际上是服务，它只是返回502的api / test.php页面

更新我移动的端口周围，我交换了networking和开发，所以开发现在在9001端口，但这没有什么区别。 我已经更新了这个问题。

所有3个端口都提供内容 – 我认为这是我为API部分设置的redirect。

这是开发和部署PHP和nginxconfiguration之间的差异：

 server:/etc/nginx/conf.d$ diff my-app-dev.conf my-app-deploy.conf 3c3 < server_name my.app.dev; --- > server_name my.app.deploy; 10c10 < root /var/www/vhosts/my-app/public_html/mobile; --- > root /var/www/vhosts/my-app/public_html/mobile_deploy; 47c47 < fastcgi_pass 127.0.0.1:9001; --- > fastcgi_pass 127.0.0.1:9002; server:/etc/php5/fpm/pool.d$ diff my-app-dev.conf my-app-deploy.conf 33c33 < listen = 127.0.0.1:9001 --- > listen = 127.0.0.1:9002 384c384 < php_admin_value[doc_root] = /var/www/vhosts/my-app/public_html/mobile --- > php_admin_value[doc_root] = /var/www/vhosts/my-app/public_html/mobile_deploy 

这里是完整的开发站点的configuration文件，在端口9001，这是给我的502
