我第一次在网络上加载Laravel应用程序（EC2）时真的卡住了。
我有一个运行最新laravel 5.6的Ubuntu 18.04示例。我花了几个小时试图解决403问题。我曾跟随：
These steps（创建新组，添加ubuntu和www-data，设置组和所有者读取，写入和执行）
These steps设置文件夹权限
...许多其他尝试/服务器重建...
所以刚才我把root中的所有文件和文件夹都设置为777来测试

$ find /home/ubuntu/projectname -type f -exec chmod 777 {} \;
$ find /home/ubuntu/projectname -type d -exec chmod 777 {} \;

根据下面的建议，我也这样做了：

$ namei -l /home/ubuntu/projectname/public
f: /home/ubuntu/projectname/public
drwxr-xr-x root     root     /
drwxr-xr-x root     root     home
drwxr-xr-x ubuntu   ubuntu   ubuntu
drwxrwxrwx www-data www-data projectname
drwxrwxrwx www-data www-data public

$ sudo chmod -R 777 /home/ubuntu/projectname

$ ls -l
drwxrwxrwx   8 www-data www-data   4096 Aug 16 10:25 app

最后一个让我困惑，因为结果与我的nginx项目错误日志（tail -f）相同：

2018/08/16 13:44:25 [error] 27246#27246: *1 directory index of "/home/ubuntu/projectname/public/" is forbidden, client: 29.99.0.232, server: projectname.com.au, request: "GET / HTTP/1.1", host: "projectname.com.au"

我不知道下一步该怎么做。* 任何帮助都会让你在我的圣诞卡名单！**
我的项目被克隆到：

/home/ubuntu/projectname

我的nginx配置（来自Laravel's Deploy page）是：
