fedora fastcgi 上的 nginx 不工作
我在 Fedora Server 22 上執行 nginx 並且 fastcgi 腳本不工作。
在http://panel.minefight.org/下輸入任何登錄數據，它不會載入密碼失敗或成功站點。其他登錄表單也會發生同樣的事情。伺服器沒有重定向使用者，我不知道如何解決這個問題。我希望這個例子很容易理解。
測試頁說，fastcgi 正在執行並與 nginx 連接。
php-fpm.conf:upstream php-fpm { server unix:/run/php-fpm/www.sock; }
php.conf:index index.php index.html index.htm; location ~ \.php$ { try_files $uri =404; fastcgi_intercept_errors on; fastcgi_index index.php; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_pass php-fpm; }錯誤日誌包含以下內容（嘗試登錄遊戲面板時）：

同樣的事情也發生在 owncloud 上。嘗試登錄owncloud時的錯誤日誌：

您遇到的問題是 PHP 無法寫入
/var/lib/php/session目錄：PHP message: PHP Warning: session_start(): open(/var/lib/php/session/sess_05tmojugo0peqvoevmlnk4ch36, O_RDWR) failed: Permission denied (13) in /mnt/ext/web/html/panel/include.php on line 52" while reading response header from upstream, client: 92.206.106.243, server: panel.minefight.org, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "panel.minefight.org"如果你查看這個目錄的權限，你會發現是這樣的：
# ls -Zld /var/lib/php/session/ drwxrwx---. 2 system_u:object_r:httpd_var_run_t:s0 root apache 44 May 15 05:26 /var/lib/php/session/但是因為您將 php-fpm 的使用者從 更改
apache為management，所以新使用者無法寫入該目錄。要解決此問題，您可以更改 php-fpm 執行的使用者和組，或者更改
/var/lib/php/session. 請注意，如果您執行後者，則每次升級 PHP（因為它嵌入到 RPM 包中）時所有權都會恢復，並且需要再次更正。我建議您在此目錄上設置 ACL，因為這不會受到升級的干擾。例如：
setfacl -m u:management:rwx,d:u:management:rwx /var/lib/php/session
