laravel 线上
Warning: require(): open_basedir restriction in effect. File(/home/wwwroot/default/laravel/bootstrap/autoload.php) is not within the allowed path(s): (/home/wwwroot/default/laravel/public/:/tmp/:/proc/) in /home/wwwroot/default/laravel/public/index.php on line 22

用的宝塔面板（测试过，可用）：
关闭防跨站攻击(open_basedir)
取消打钩，重新保存，并重启php
其他方法（不知是否可行）：
1.删除user.ini
2.在nginx的fastcgi.conf配置文件中
删除或注释掉这一行fastcgi_param PHP_ADMIN_VALUE "open_basedir=$document_root/:/tmp/:/proc/";
3.也有资料说将fastcgi_param PHP_ADMIN_VALUE"open_basedir=$document_root/:/tmp/:/proc/";改成：fastcgi_param PHP_ADMIN_VALUE "open_basedir=NULL"; 然后重启一下服务
4.如果你是PHP 5.3.3以上的版本，可以修改/usr/local/php/etc/php.ini在末尾里加入：
[HOST=www.project.com]
open_basedir=/home/wwwroot/default/laravel/:/tmp/
[PATH=/home/wwwroot/default/laravel/public]
open_basedir=/home/wwwroot/default/laravel/:/tmp/
