一.环境:

centos6.7 x86_64 位最小化安装
[root@cacti conf.d]# cat /etc/redhat-release 
CentOS release 6.7 (Final)
[root@cacti conf.d]# uname -a
Linux cacti 2.6.32-573.el6.x86_64 #1 SMP Thu Jul 23 15:44:03 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

httpd是 yum 安装

yum install httpd -y

[root@cacti conf.d]# httpd -v

Server version: Apache/2.2.15 (Unix)
Server built: Jul 18 2016 15:24:00

二.apache httpd.conf 配置文件配置允许特定的IP访问网站

配置如下：

User apache
Group apache
ServerAdmin root@localhost
ServerName 127.0.0.1:80
UseCanonicalName Off
DocumentRoot "/var/www/html"
<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
Allow from 124.207.48.224
Allow from 192.168.1.10
Allow from 121.69.37.66 
Allow from 192.168.10.100
</Directory>

先拒绝所有：Deny from all 后面加上所允许的特定IP地址访问 /var/www/html 这个目录下的内容。

[root@cacti conf.d]# cat /etc/httpd/conf/httpd.conf

ServerAlias 201.195.2.245
</VirtualHost>

三.vhost虚拟主机通过指定不同的端口来提供不同的服务:

vhost虚拟主机配置格式如下：

Listen 10300NameVirtualHost *:10300
      
       ServerName 201.195.10.245:10300DocumentRoot "/var/www/html/itop"
      Listen 10400NameVirtualHost *:10400
      
       ServerName 201.195.10.245:10400DocumentRoot "/var/www/html/kjxw_zabbix"

四.vhost虚拟主机通过不同的域名指向不同的web站点来提供不同的服务
