如何实现apache虚拟主机配置。
1、基于ip地址的虚拟主机
Listen 80
<VirtualHost 172.20.30.40>
DocumentRoot /home/httpd/html1
ServerName www.ok1.com
ErrorLog /usr/local/apache/logs/error1_log
CustomLog /usr/local/apache/logs/access1_log combined
</VirtualHost>
<VirtualHost 172.20.30.50>
DocumentRoot /home/httpd/html2
ServerName www.ok2.com
ErrorLog /usr/local/apache/logs/error2_log
CustomLog /usr/local/apache/logs/access2_log combined
</VirtualHost>
2、基于IP 和多端口的虚拟主机配置
Listen 172.20.30.40:80
Listen 172.20.30.40:8080
Listen 172.20.30.50:80
Listen 172.20.30.50:8080
<VirtualHost 172.20.30.40:80>
DocumentRoot /www/example1-80
ServerName www.example1.com
</VirtualHost>
<VirtualHost 172.20.30.40:8080>
DocumentRoot /www/example1-8080
ServerName www.example1.com
</VirtualHost>
<VirtualHost 172.20.30.50:80>
DocumentRoot /www/example2-80
ServerName www.example1.org
</VirtualHost>
<VirtualHost 172.20.30.50:8080>
DocumentRoot /www/example2-8080
ServerName www.example2.org
</VirtualHost>
3、单个IP 地址的服务器上基于域名的虚拟主机配置
# Ensure that Apache listens on port 80
Listen 80
# Listen for virtual host requests on all IP addresses
NameVirtualHost *:80
<VirtualHost *:80>
DocumentRoot /www/example1
ServerName www.example1.com
ServerAlias example1.com. *.example1.com
# Other directives here
</VirtualHost>
<VirtualHost *:80>
DocumentRoot /www/example2
ServerName www.example2.org
# Other directives here
</VirtualHost>
如果您感觉上面的文章还不够详细可以看下下面的文章：
实验目标：在apache实现基于域名的虚拟主机
实验用的XAMPP版本为1.7.7，内含apache版本为2.2.21
实验前准备：
1. 为了测试不同的域名，在Windows/System32/drivers/etc/下觅得hosts文件，在其中添加实验用的域名若干，如 -
127.0.0.1 test1.net
127.0.0.1 test2.net
如此，则在浏览器中输入该俩域名时，Windows将其解析为127.0.0.1本地地址。即，在浏览器中访问localhost, test1.net, test2.net均可访问XAMPP的欢迎页。
2. 在apache目录下建立目录，以放置您不同的网站。为保护XAMPP原有的htdocs中的欢迎页内容，实验另外建立了与htdocs平级的htdocs1目录，在其下建立了test1.net, test2.net两个子目录用以放置实验用的网站。如下 -
apache/htdocs1/test1.net - 放置test1.net网站内容
apache/htdocs1/test2.net - 放置test2.net网站内容
在这两个目录中各新建hello world一网页 index.html，内容 -
<HTML>
<HEAD></HEAD>
<BODY>
<H1>hello~, 这是[对应的网站名，用以区别].net</H1></BODY>
</HTML>
实验步骤：
1. 找到apache/conf/httpd.conf, 将其中的
ServerAdmin
ServerName
DocumentRoot
注释掉。
2. 在httpd.conf中，找到行
Include "conf/extra/httpd-vhosts.conf"
如被注释则解注。该文件记载了虚拟主机的参数。[以前虚拟主机参数是直接填写在httpd.conf中的，为了更好地组织文件，将其分离出去，类似于某些编程语言一样。因此httpd.conf中include它，即相当于把它的内容填在了httpd.conf中。]
3. 这个httpd-vhosts.conf文件格式基本如下 -
#blah-blah
NameVirtualHost *:80
#blah-blah
#blah-blah
<VirtualHost *:80>
ServerAdmin XXXXXXXX
DocumentRoot "XXXXXXXX"
ServerName XXXXXXX
ServerAlias XXXXXX
ErrorLog "logs/XXXXXX-error.log"
CustomLog "logs/XXXXXXX-error.log" combined
</VirtualHost>
需要修改的，就是<VirtualHost>中的参数了。这个可以参见apache官方文档。根据实验域名，可以增加两个<VirtualHost>：
<VirtualHost *:80>
ServerAdmin adm@test1.net
DocumentRoot "C:/xampp/htdocs1/test1.net"
ServerName test1.net
ServerAlias www.test1.net
ErrorLog "logs/test1-error.log"
CustomLog "logs/test1-access.log" combined
<Directory "C:/xampp/htdocs1/test1.net">
order allow,deny
allow from all
</Directory>
</VirtualHost>
<VirtualHost *:80>
ServerAdmin adm@test2.net
DocumentRoot "C:/xampp/htdocs1/test2.net"
ServerName test2.net
ServerAlias www.test2.net
ErrorLog "logs/test1-error.log"
CustomLog "logs/test1-access.log" combined
<Directory "C:/xampp/htdocs1/test2.net">
order allow,deny
allow from all
</Directory>
</VirtualHost>
注意，如果不在各VirtualHost中定义Directory的可访问性，你将遇到的是Access Forbidden!就连原来的localhost也是。
4. 由于之前注释掉了httpd.conf中的ServerName, DocumentRoot等，为了仍然能以localhost访问原XAMPP欢迎页，就在增加一个VirtualHost，如下 -
<VirtualHost *:80>
ServerAdmin adm@localhost
DocumentRoot "C:/xampp/htdocs"
ServerName localhost
ErrorLog "logs/localhost-error.log"
CustomLog "logs/localhost-access.log" combined
<Directory "C:/xampp/htdocs">
order allow,deny
allow from all
</Directory>
</VirtualHost>
为了避免出错，把它放置在第一个Virtualhost位置。
至此，apache基于域名的虚拟主机配置完成。可以通过http://localhost访问XAMPP欢迎页，通过http://test1.net和http://test2.net访问各自的主页。

# Virtual Hosts
#
# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs/2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.
#
# Use name-based virtual hosting.
#
NameVirtualHost *:80
#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#
<VirtualHost *:80>
