apache documentroot指向htcdoc之外提示403错误的解决方法

后来发现，原来又是Apache没配置好，是apache的mod_authz_host模块在起控制作用。
1.如果不启用vhosts
只需修改 httpd.conf
默认Directory节如下，注意红色部分，表示目录/usr/local/apache/htdocs允许所有主机访问

复制代码代码如下:

	
	<Directory "/usr/local/apache/htdocs">

	#

	# Possible values for the Options directive are "None", "All",

	# or any combination of:

	# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

	#

	# Note that "MultiViews" must be named *explicitly* --- "Options All"

	# doesn't give it to you.

	#

	# The Options directive is both complicated and important. Please see

	# http://httpd.apache.org/docs/2.2/mod/core.html#options

	# for more information.

	#

	#Options Indexes FollowSymLinks

	#

	# AllowOverride controls what directives may be placed in .htaccess files.

	# It can be "All", "None", or any combination of the keywords:

	# Options FileInfo AuthConfig Limit

	#

	AllowOverride None

	#

	# Controls who can get stuff from this server.

	#

	Order allow,deny

	Allow from all

	</Directory>

由于主目录被指到别的地方了，所以将蓝色部分/usr/local/apache/htdocs换成你新的主目录就OK了。
2.启用vhosts
启用vhosts的话，你就可以不作上面的修改了，因为VirtualHost可以单独配置这个节的属性，所以我们在VirtualHost这个节里配置的话就更方便了，下面的配置中，我把我的网站放在/var/vhosts/www.test.cn下。

复制代码代码如下:

	
	/usr/local/apache/conf/extra/httpd-vhosts.conf

	<VirtualHost *:80>

	<Directory "/var/vhosts/www.test.cn" >

	#Deny from all

	Allow from all

	</Directory>

	DocumentRoot "/var/vhosts/www.test.cn"

	ServerName www.test.cn

	</VirtualHost>

如果把Deny from all的注释去掉，那么服务器就会拒绝所有访问（和我们刚开始把主目录移动到htdocs外而没做任何配置修改时一样，哈哈）
补充一点：
如果你是写个index.php放在目录下测试，可要注意了，记得加上默认主页index.php
DirectoryIndex index.html index.php
