require(): open_basedir restri

LNMP環境安裝Laravel，在nginx.conf將root指向項目的public目錄的時候（如：root /home/wwwroot/laravel/public），瀏覽器運行報500錯誤，錯誤信息為：
Warning: require(): open_basedir restriction in effect. File(/home/wwwroot/laravel/vendor/autoload.php) is not within the allowed path(s): (/home/wwwroot/laravel/public/:/tmp/:/proc/:/home/wwwroot/laravel/public/) in /home/wwwroot/laravel/public/index.php on line 24

Warning: require(/home/wwwroot/laravel/vendor/autoload.php): failed to open stream: Operation not permitted in /home/wwwroot/laravel/public/index.php on line 24

Fatal error: require(): Failed opening required '/home/wwwroot/laravel/public/../vendor/autoload.php' (include_path='.:/usr/local/php/lib/php') in /home/wwwroot/laravel/public/index.php on line 24

1、查找php.ini 發現“open_basedir”為注釋狀態
2、查看nginx下的fastcgi.conf ，發現“fastcgi_param”參數如下
fastcgi_param PHP_ADMIN_VALUE "open_basedir=$document_root/:/tmp/:/proc/";
這里的$document_root 就是 nginx中定義的root的目錄
3、修改nginx下的fastcgi.conf，在后面追加上項目的根目錄，如下：
fastcgi_param PHP_ADMIN_VALUE "open_basedir=$document_root/:/tmp/:/proc/:/home/wwwroot/laravel/";
4、重啟lnmp ，錯誤消失。
