Question

我在Xubuntu 14.04机器的本地目录中有一个Heroku PHP项目。

我想在本地运行它，以便在部署Heroku之前开发/测试它。

首先，我尝试进入项目目录并运行foreman start web。

有些错误的包与PHP版本有关，所以我做了以下内容：

1）。从自定义PPA安装最新的PHP版本（ ppa：ondrej / php5 ）：

php --version

PHP 5.5.18-1+deb.sury.org~trusty+1 (cli) (built: Oct 17 2014 15:20:47)。

2）。为php5-fpm二进制文件创建了一个符号链接：

sudo ln -s /usr/sbin/php5-fpm /usr/local/bin/php-fpm

3）。已安装 nginx 。

4）。更改了 Procfile ：

web: vendor/bin/heroku-php-nginx /web

接下来，我正在尝试使用：foreman start web命令启动服务器，我得到以下输出：

02:38:23 web.1  | started with pid 15815
02:38:23 web.1  | Booting on port 5000...

02:38:26 web.1  | exited with code 1
02:38:26 system | sending SIGTERM to all processes

显然，它无法启动，因为它无法访问root用户拥有的日志文件。

接下来，我尝试使用 sudo ：sudo foreman start web启动它并获得以下输出：

02:43:29 web.1  | started with pid 16153
02:43:30 web.1  | Booting on port 5000...

看起来它不喜欢nginx服务正在运行。那是为什么？

我正在使用：sudo service nginx stop关闭网络服务器并再次尝试。

这次没有错误消息，看起来服务器正在运行。

但是，当我在浏览器中加载网页时，我收到HTTP的 502 Bad Gateway 错误。

从nginx错误日志中我可以看到nginx无法访问FastCGI套接字文件：

2014/11/06 02:45:44 [crit] 16342#0: *1 connect() to unix:/tmp/heroku.fcgi.5000.sock failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/tmp/heroku.fcgi.5000.sock:", host: "localhost:5000"。

套接字文件由root拥有，nginx以www-data运行。

这是什么原因，我该如何解决这个问题？是否可以从我的用户（不是root用户）本地运行Heroku？

Answer 1

我有同样的问题（在Mac OS上，使用自制软件重新安装nginx）。

我没有编辑vendor/heroku/heroku-buildpack-php/conf/nginx/heroku.conf.php（在任何时候更新后都会覆盖它，而且现在它有点不同）。

我刚刚修复了错误日志文件的权限（对其进行了编码），然后正常运行heroku local

如果你以root身份运行heroku local，这将解决你的错误日志权限错误，但是然后nginx以root身份运行，php-fpm以无人运行（在我的情况下），因此上面说明了权限不匹配。

如果您修复了权限，然后运行heroku local（没有sudo），那么两个都是无人运行，而且对我有效。

你的情况和我一模一样。

问题是关于nginx和php5-fpm的进程之间的差异权限。快速修复：

首先：

编辑文件：vendor / heroku / heroku-buildpack-php / conf / nginx / heroku.conf.php

评论：#server unix：/tmp/heroku.fcgi..sock max_fails = 3 fail_timeout = 3s;

打开评论并更改端口：服务器127.0.0.1:9000 max_fails = 3 fail_timeout = 3s;

第二

编辑文件：vendor / heroku / heroku-buildpack-php / conf / php / php-fpm.conf

评论：listen = /tmp/heroku.fcgi。$ {PORT} .sock

打开评论并更改端口：listen = 127.0.0.1:9000

在Ubuntu中使用Foreman在本地运行Heroku PHP项目时权限不正确
