谷歌和各种其他搜索引擎,但仍然无法解决它.
这是我的场景：

Larave 5 on homestead

1)ps -eo pid,comm,euser,supgrp | grep nginx
[以下是输出]

2333 nginx root root
2335 nginx vagrant adm,cdrom,sudo,dip,www-data,plugdev,lpadmin,sambashare,vagrant

2)根据一些搜索结果,确实做了以下内容：/etc/php/7.0/fpm/pool.d

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

3)用sudo服务输出php7.0-fpm restart

• Restarting PHP 7.0 FastCGI Process Manager php-fpm7.0 [ OK ]

4)使用sudo服务nginx重启输出

nginx stop/waiting
nginx start/running, process 2650

5)输出：

sudo /etc/init.d/nginx restart

• Restarting nginx nginx [fail]

6)输出：tail -f /var/log/nginx/error.log

我对这个502 Bad Gateway感觉很糟糕

> nginx/1.9.7

和PHP

> PHP 7.0.1-1+deb.sury.org~trusty+2 (cli) ( NTS )

如果有人能帮我继续这种情况,那就太好了.并且,提前谢谢你.

解决方法:

终于解决了这个here.我要感谢Miguel从laracast讨论.

您需要在以下位置更改配置文件：

/etc/nginx/sites-enabled

change line fastcgi_pass for

 fastcgi_pass unix:/run/php/php7.0-fpm.sock;

php7.0-fpm.sock位于：

/var/run/php

由于新VM使用php 7. *,您的配置文件可能具有5.6版本的php位置.
