权限 - MacOSX配置php开发环境，apache显示Forbidden

系统：macos 10.8.3
初始条件都设置完毕，但是更改了apache Documentroot 环境配置更改到自己程序的运行路径就不能成功。不知道是不是权限的问题。
在系统的默认路径就能够执行php。但是更换路径显示
You don't have permission to access / on this server. 权限已经加上去了，不知道少了啥么？ 还有啥需要补充的~

# 'Main' server configuration

# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <virtualhost> definition.  These values also provide defaults for

#
# All of these directives may appear inside <virtualhost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#

# ServerAdmin: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#
ServerAdmin you@example.com

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.

    # Example:
    # Redirect permanent /foo http://www.example.com/bar

    #
    # Alias: Maps web paths into filesystem paths and is used to

    # If you include a trailing / on /webpath then the server will

    # ScriptAliases are essentially the same as Aliases, except that

    # client.  The same rules about trailing "/" apply to ScriptAlias

    #AddHandler type-map var

    #
    # Filters allow you to process content before it is sent to the client.

# 'Main' server configuration
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <virtualhost> definition.  These values also provide defaults for
# any <virtualhost> containers you may define later in the file.
#
# All of these directives may appear inside <virtualhost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#

#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#
ServerAdmin you@example.com

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
#ServerName www.example.com:80

#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.

    # Redirect: Allows you to tell clients about documents that used to

    # Example:
    # Redirect permanent /foo http://www.example.com/bar

    #
    # Alias: Maps web paths into filesystem paths and is used to
    # access content that does not live under the DocumentRoot.
    # Example:
    # Alias /webpath /full/filesystem/path
    #
    # If you include a trailing / on /webpath then the server will
    # require it to be present in the URL.  You will also likely

    # client.  The same rules about trailing "/" apply to ScriptAlias

AllowOverride None
Order deny,allow
allow from all

两个选择：

1.不折腾，直接用 WAMP 就好了。 http://www.wampserver.com/en/

2.想折腾，就用虚拟机配置环境，比直接在 Mac OS 上配置要强太多。
