NginX + PHP-FPM 顯示空白 php 頁面
我有一個問題，我的伺服器使用 php-fpm 執行 NginX 載入空白 PHP 頁面（奇怪的是，我的 phpinfo.php 文件除外，它正常載入）。如果我將 index.html 頁面放在同一目錄中並瀏覽到它，它就會載入。phpinfo.php（呼叫 phpinfo(); 函式）載入的事實證實了 php-fpm 有效。
我希望有人能給點建議。對於我即將提供的大量資訊，我提前道歉，但我寧願提供太多資訊而不是太少。這是我的配置文件。

server_name mydmaiin.nl;<– 這對於每個伺服器塊都是唯一的。
root /var/www/mydomain.nl/public_html/;<– 這是保存您的網站/數據的根目錄。其餘的都是微不足道的。
因此，讓我們拿起
/etc/php-fpm.d/www.conf文件並檢查一下。您選擇使用文件套接字
listen = /var/run/php-fpm/php-fpm.sock<– php-fpm 將nginx通過此文件進行通信。所以這是我的www.conf文件，除非你錯過了什麼。我已經過濾掉了所有的註釋行。所以這些是未註釋的行。[www] listen = /var/run/php5-fpm.sock listen.allowed_clients = 127.0.0.1 listen.owner = nginx listen.group = nginx listen.mode = 0666 user = apache group = apache pm = dynamic pm.max_children = 50 pm.start_servers = 5 pm.min_spare_servers = 5 pm.max_spare_servers = 35 slowlog = /var/log/php-fpm/www-slow.log security.limit_extensions = .php php_admin_value[error_log] = /var/log/php-fpm/www-error.log php_admin_flag[log_errors] = on php_value[session.save_handler] = files php_value[session.save_path] = /var/lib/php/session故障排除
