nginx File not found 错误

nginx配置php老是出错，浏览器打开php脚本报File not found错误，最后才发现是$document_root的设置问题。

location ~ \.php$ {
    root           html;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

这个用出现找不到php的错误。因为$document_root的参数是由root html那一行定义的，默认是在/etc/nginx/html/所以把html换成站点根目录就正常了。

location ~ \.php$ {
    root           /usr/share/nginx/html;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}
