Apache的访问控制有两种:一是对目录进行限制,一是对文件进行限制。依次介绍这两种访问控制方式。我们的虚拟机有两个IP:一个127.0.0.1,另一个192.168.147.132。如果我们不想让其中一个IP比如127.0.0.1访问我们的网站。(其实主要是限制别人,不是限制自己,这里只是举例子)
编辑虚拟主机配置文件
[root@centos6 ~]# vim /usr/local/apache2/conf/extra/httpd-vhosts.conf
添加限制127.0.0.1访问网站根目录的访问控制方法:
……
ServerName www.test.com
ServerAlias www.aaa.com
ServerAlias www.bbb.com
<Directory "/data/www">
AllowOverride None
Options None
Order allow,deny
Allow from all
Deny from 127.0.0.1
</Directory>
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.aaa.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.bbb.com$
RewriteRule ^/(.*)$ http://www.test.com/$1 [R=301,L]
</IfModule>
……
按Order顺序匹配,与下面Allow行和Deny行的先后无关。这里Order顺序为先看allow,再看deny,
所以先允许所有的IP访问,再禁止127.0.0.1的访问,最终结果是127.0.0.1被禁止。
检查无误后重新加载配置文件,可以看到我们做到了拒绝127.0.0.1的访问,192.168.147.132仍可访问

我们网站后台肯定不能对任意IP开放访问,比如只能允许在本机登录后台,则需要对后台管理admin.php做白名单:正常情况下,所有人都能看到这个页面,这样不合适
在虚拟主机配置文件中加入如下内容:只允许127.0.0.1访问admin.php
……
<Directory "/data/www">
AllowOverride None
Options None
Order allow,deny
Allow from all
Deny from 127.0.0.1
</Directory>
<filesmatch "(.*)admin(.*)">
Order deny,allow
Deny from all
Allow from 127.0.0.1
</filesmatch>
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.aaa.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.bbb.com$
RewriteRule ^/(.*)$ http://www.test.com/$1 [R=301,L]
</IfModule>
……
检查无误后重新加载配置文件,可见现在只允许127.0.0.1登入后台管理,不能通过192.168.147.132访问后台管理了,这样就安全了。
