出現“您要查找的頁面暫時不可用，請稍後再試”
我有一個執行Ubuntu+LEMP +Varnish 的 vps。一切都很好，直到我更新了伺服器軟體。
現在我在每個頁面上都收到“您要查找的頁面暫時不可用。請稍後再試”。（標題響應為 502）
我試著弄清楚。這是我在更新時得到的。

更新伺服器後我遇到了同樣的錯誤，在 /var/log/nginx/error.log 中發現了以下錯誤：
/var/run/php5-fpm.sock failed (13: Permission denied)解決問題的方法是取消註釋 /etc/php5/fpm/pool.d/www.conf 中的以下行並重新啟動 php5-fpm
listen.owner = www-data listen.group = www-data listen.mode = 0660
我也有同樣的錯誤，我不得不輸入 /etc/nginx/nginx.conf
user www-data www-data;
