尝试在 Debian Vagrant Box 上使用 PHP 和 nginx 编写会话时出现 502 Bad Gateway

我正在使用一个装有以下物品包装的Vagrant盒子。Debian 8.5

tmux curl wget nginx php7.0-fpm php7.0-cli php7.0-curl php7.0-gd php7.0-intl php7.0-mysql php7.0-memcached memcached php-mbstring php-xml mariadb-server nodejs git unzip zip

我的问题是，当我尝试在任何目录中写入会话（例如登录后）时出现错误502 Bad Gateway。

包含/var/log/nginx/error.log以下内容

2016/07/18 21:31:59 [error] 15674#15674: *8 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 192.168.60.1, server

当我启用调试日志时这是输出。问题是，我并不认为这是一个权限问题，因为文件正在写入目录，甚至还有内容。但我仍然得到 502。

如果你需要更多信息，我会提供给你。只要问就可以。

更新
我刚刚从 Debian 切换到 Ubuntu，问题仍然存在，所以这不是 Debian 的问题（而且由于我从 Symfony 切换到 Laravel，所以这也不是 Symfony/Laravel 的问题）。这意味着可能是Vagrant，NFS也许？或者Nginx做错了什么

当使用 laravel 时这是日志。

[2016-07-23 19:03:56] local.ERROR: ErrorException: file_put_contents(): Exclusive locks are not supported for this stream in /var/www/project/www/vendor/laravel/framework/src/Illuminate/Filesy$

不知怎的，我认为这一定是 Vagrant 错误，因为当我尝试执行此操作时，sudo chown -R project:project /var/www/project/www我收到了错误

chown: changing ownership of ‘{ANY FILE/FOLDER}’: Operation not permitted

答案1

这是一个老问题，所以我真的希望你现在已经解决了。

对于仍然面临此问题的任何人来说，我可以通过以下方式file_put_contents(): Exclusive locks are not supported for this stream设置来解决问题：Vagrantfile

config.vm.synced_folder ".", "/vagrant", 
    :nfs => true, 
    :nfs_version => 4, 
    :nfs_udp => false, 
    :mount_options => ['sec=sys']

vagrant reload更新后别忘了运行Vagrantfile。
