我正在Fedora服务器22上运行nginx，而fastcgi脚本不能正常工作。
在http://panel.minefight.org/下input任何login数据，它不会加载密码失败或成功的网站。 其他login表单也会发生同样的情况。 服务器没有redirect用户，我不知道如何解决这个问题。 我希望这个例子很容易理解。
testing页面说，fastcgi正在运行，并与nginx连接。
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; }
错误日志包含以下内容（当试图logingamepanel时）：

奇怪的是，它是在Apache下工作。 游戏平台论坛中的用户也报告了这一点：“这似乎是与nginx正确redirect和存储会话的问题。”
同一件事发生在owncloud。 尝试在owncloud中login时的错误日志：

如果用户使用参数“？id = 1”访问phpinfo.php站点，则错误日志包含以下内容：
2015/05/30 22:35:16 [crit] 2036#0: *7 open() "/var/lib/nginx/tmp/fastcgi/1/00/0000000001" failed (13: Permission denied) while reading upstream, client: 92.206.106.243, server: minefight.org, request: "GET /phpinfo.php?id=1 HTTP/1.1", upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "minefight.org"
您遇到的问题是PHP无法写入/var/lib/php/session目录：
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"
如果你看看这个目录的权限，你会发现这样的：
# 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/
但是因为你把php-fpm的用户从apache改为management ，新用户不能写入这个目录。
要解决这个问题，可以更改php-fpm运行的用户和组，或者更改/var/lib/php/session的所有权。 请注意，如果你使用后者，所有权将在每次升级PHP时都会恢复（因为它被embedded到RPM包中），并且需要再次修正。
我build议你在这个目录上设置一个ACL，因为这不会受到升级的干扰。 例如：
setfacl -mu:management:rwx,d:u:management:rwx /var/lib/php/session
