        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

}

编译一个php测试页面

cat /usr/local/nginx/html/info.php
<?php
phpinfo();

访问：

http://project1.example.com/info.php

问题1：页面提示 文件找不到

查看nginx日志如下提示

2024/07/27 07:50:20 [error] 56623#0: *172 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 117.129.44.196, server: project1.example.com, request: "GET /info.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm.sock:", host: "project1.example.com"

2、通过排除法定位问题

首先: 要保障这俩用户是一致的，selinux和防火墙是关闭的

egrep "user = nginx|group = nginx" /etc/php-fpm.d/www.conf
egrep "user nginx nginx" /data/apps/nginx/conf/nginx.conf

其次：排除目录权限的问题

大家可能都有自己的自定义项目目录。

遇到问题拍错的时候建议先按最小化配置也就是我上面的示例去测试

然后检查项目上一级目录、项目目录是不是都是755
