The standard solution in these situations is to use the Apache Web server’s mod_rewrite module to allow for “prettier” URLs. mod_rewrite is a tool that lets you instruct the server that when the user goes to one URL, the server should provide another resource. mod_rewrite makes use of regular expressions, so the matching pattern and resulting actual URL can be as complex as needed.
These, and other changes to Apache’s behavior, can be made in two ways: by editing the primary Apache configuration file or by creating directory-specific files. The primary configuration file is httpd.conf, found within a conf directory, and it dictates how the entire Apache Web server runs (where the httpd.conf file is on your system will depend on many things). An .htaccess
file (pronounced “H-T access”) is placed within a Web directory and is used to affect how Apache behaves within just that folder and subfolders.
Generally speaking, it’s preferable to make changes in the httpd.conf file, since this file needs to be read only by the Web server each time the server is started. Conversely, .htaccess files must be read by the Web server once for every request to which an .htaccess file might apply.

Apache的Order Allow,Deny 详解


Allow和Deny可以用于apache的conf文件或者.htaccess文件中（配合Directory, Location, Files等），用来控制目录和文件的访问授权。






所以，最常用的是：
Order Deny,Allow
Allow from All


注意“Deny,Allow”中间只有一个逗号，也只能有一个逗号，有空格都会出错；单词的大小写不限。上面设定的含义是先设定“先检查禁止设定，没有禁止的全部允许”，而第二句没有Deny，也就是没有禁止访问的设定，直接就是允许所有访问了。这个主要是用来确保或者覆盖上级目录的设置，开放所有内容的访问权。


按照上面的解释，下面的设定是无条件禁止访问：
Order Allow,Deny
Deny from All


如果要禁止部分内容的访问，其他的全部开放：
Order Deny,Allow
Deny from ip1 ip2
或者
Order Allow,Deny
Allow from all
Deny from ip1 ip2


apache会按照order决定最后使用哪一条规则，比如上面的第二种方式，虽然第二句allow允许了访问，但由于在order中allow不是最后规则，因此还需要看有没有deny规则，于是到了第三句，符合ip1和ip2的访问就被禁止了。注意，order决定的“最后”规则非常重要，下面是两个错误的例子和改正方式：


Order Deny,Allow
Allow from all
Deny from domain.org
错误：想禁止来自domain.org的访问，但是deny不是最后规则，apache在处理到第二句allow的时候就已经匹配成功，根本就不会去看第三句。
解决方法：Order Allow,Deny，后面两句不动，即可。


Order Allow,Deny
Allow from ip1
Deny from all
错误：想只允许来自ip1的访问，但是，虽然第二句中设定了allow规则，由于order中deny在后，所以会以第三句deny为准，而第三句的范围中又明显包含了ip1（all include ip1），所以所有的访问都被禁止了。
解决方法一：直接去掉第三句。
解决方法二：
Order Deny,Allow
Deny from all
Allow from ip1


下面是测试过的例子：
--------------------------------
Order deny,allow
allow from all
deny from 219.204.253.8
#全部都可以通行
-------------------------------
Order deny,allow
deny from 219.204.253.8
allow from all
#全部都可以通行
-------------------------------
Order allow,deny
deny from 219.204.253.8
allow from all
#只有219.204.253.8不能通行
-------------------------------
Order allow,deny
allow from all
deny from 219.204.253.8
#只有219.204.253.8不能通行
-------------------------------
-------------------------------
Order allow,deny
deny from all
allow from 219.204.253.8
#全部都不能通行 
-------------------------------
Order allow,deny
allow from 219.204.253.8
deny from all
#全部都不能通行
