我正在运行一个 vpsUbuntu+LEMP+Varnish。在我更新服务器软件之前，一切都很好。
现在我在每个页面上都收到“您正在寻找的页面暂时不可用。请稍后重试”。 （标头响应为 502）
我尝试弄清楚。以下是我更新时得到的结果。

What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions

这些更新与以下内容相关：http://www.ubuntu.com/usn/usn-2254-1/
答案1
更新服务器后我遇到了同样的错误，并在 /var/log/nginx/error.log 中发现以下错误：/var/run/php5-fpm.sock failed (13: Permission denied)
解决问题的方法是取消注释 /etc/php5/fpm/pool.d/www.conf 中的以下行并重新启动 php5-fpm
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
答案2
我也遇到了同样的错误，我不得不输入/etc/nginx/nginx.conf
user www-data www-data；
