本文介绍了解决新服务器环境中因SELinux配置导致的文件不存在错误的过程。通过调整SELinux模式为permissive或禁用SELinux，解决了这一难题。

新搭服务器环境，遇到这个奇葩问题，各种配置文件都是从原始服务器copy过来的，原环境没问题，放到这个新的服务器就是提示文件不存在，各种看日志，改权限，完全无解，偶然间google到一个SELinux，顿时豁然开朗，记录一下。

查看 SELinux状态及关闭SELinux

1、临时关闭（不用重启机器）：

setenforce 0          ##设置SELinux 成为permissive模式

                              ##setenforce 1 设置SELinux 成为enforcing模式

2、修改配置文件需要重启机器：

修改/etc/selinux/config 文件

将SELINUX=enforcing改为SELINUX=disabled

重启机器即可

这样真的可以吗，再次运行，恭喜你，还是报了FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream，为啥呢，因为$fastcgi_script_name此时还是/b，所以这样的真实访问路径就变成了/b/public/b,但是这个路径并不存在，所以就报错了，并且这么改还有个更大的问题，就是这么做了之后，怎么访问/a/public呢？

Nginx报错：FastCGI sent in stderr: “Primary script unknown“ while reading response header from upstream

在Nginx转发PHP文件到PHP-FPM服务时，出现“Primary script unknown”错误，原因是Nginx配置中未正确定义root根目录，导致无法找到指定的PHP文件。通过以下三种方式可以解决该问题：1. 在location ~ \.php$块中添加root配置；2. 在server块中定义全局root路径；3. 将fastcgi_param SCRIPT_FILENAME中的$document_root替换为绝对路径。这些方法确保Nginx能够正确解析PHP文件的路径，从而避免错误。

这类文件仅会被cgi/fast cgi/sapi处理，次文件会使得pecl 的htscanner扩展作废，所以路径没填写正确会产生这样的异常。如果使用apache，则用.hataccess 有同样的效果。至于user.ini 文件是什么 https://www.php.net/manual/zh/configuration.file.per-user.php#111834 中有介绍。出现这类问题时，需要检查一下nginx定位的网站根目录中，是否有user.ini 文件。

因为换了台电脑，不可避免的要重新折腾一次开发环境。 开发环境是LNMP，部署好站点后，访问站点的时候始终是“File Not Found”，于是就见了鬼了，历来环境都是这么弄的，配置的内容也是根据之前的配置copy的，路径都确认了没得问题的。所以，真的就见了鬼了。 一般有问题都要找哥找娘的，但是说法大都是说讲配置SCRIPT_FILENAME不对，应该怎样怎样改，这里就是最不解
