用MAMP搭建本地服务器的时候，设置好ip和端口等属性之后，浏览器访问，报 403错误：
Forbidden
You don't have permission to access / on this server.
google之后，stackoverflow已有类似的问题：/questions/10873295/error-message-forbidden-you-dont-have-permission-to-access-on-this-server
主要有以下方法是：
将 /Application/MAMP /conf/ apache/httpd.conf 中的如下部分
<Directory />
Options FollowSymLinks
AllowOverride All
Order deny,allow
Allow from all
</Directory>
set the options to : Options Indexes FollowSymLinks Includes ExecCGI
改成：
<Directory />
#Options FollowSymLinks
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Order deny,allow
Allow from all
</Directory>
也有人提出是访问权限的问题，就是进程的拥有者没有访问Document root的权限，原话如下：
Also, one should check the folder's permissions so that the Apache process' owner has permissions to read/execute the specified path for the virtual host. On Windows this could rarely be a problem but on Linux it can be a more frequent cause of 403.
看到这我才想到原来我将Document root 设在了桌面。而我直接访问Document root，就报错了。如果访问目录下的某个文件就没问题。
