Apache配置虚拟目录和多主机头

呃，相当古老的话题了，不过网上的资料实在是太坑爹，无奈只能自己动手做个备忘了。。。
这里不提虚拟目录和主机头的区别了，不懂得童鞋去面壁思过吧

多个虚拟目录

　　首先把Apache安装到D:\Program Files\Apache2.2目录下，端口号设置为8080，安装完成后默认的网站根目录为D:\Program Files\Apache2.2\htdocs，通常我们可以在htdocs下面建立个文件夹MySite，然后在浏览器输入：http://localhost:8080/MySite 这样就可以看到我们自己的站点了。然而有时我们想把站点放到其它目录下面，这时就需要配置虚拟目录了
比如我们在D盘建立如下文件夹D:\Code\WebSite，然后通过http://localhost:8080/DemoSite来访问这个站点

打开httpd.conf文件，搜索<IfModule alias_module> 节点，然后在节点内输入以下内容:

<IfModule alias_module>
#
# Redirect: Allows you to tell clients about documents that used to
# exist in your server's namespace, but do not anymore. The client
# will make a new request for the document at its new location.
# Example:
# Redirect permanent /foo http://localhost/bar 
#
# Alias: Maps web paths into filesystem paths and is used to
# access content that does not live under the DocumentRoot.
# Example:
# Alias /webpath /full/filesystem/path
#
# If you include a trailing / on /webpath then the server will
# require it to be present in the URL.  You will also likely
# need to provide a <Directory> section to allow access to
# the filesystem path.

#
# ScriptAlias: This controls which directories contain server scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the target directory are treated as applications and
# run by the server when requested rather than as documents sent to the
# client.  The same rules about trailing "/" apply to ScriptAlias
# directives as to Alias.
#
ScriptAlias /cgi-bin/ "D:/Program Files/Apache2.2/cgi-bin/"

Alias /DemoSite "D:/Code/WebSite"

<Directory "D:/Code/WebSite">
Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>
</IfModule>

多主机头绑定
（就是在一个端口上绑定多个域名，然后每个域名可以指向不同的目录进行访问，主机头是IIS里面的说法），打开httpd.conf文件，在文件最后添加如下内容

#多主机头配置无需放在特定的节点下面，一般直接在配置文件底部添加即可
#NameVirtualHost addr[:port] 为一个基于域名的虚拟主机指定一个IP地址(和端口)
#声明主机头必须加这条指令，否者主机头配置不会生效
#VirtualHost节点下面ServerName就是要绑定的域名，DocumentRoot表示此域名指向的目录
#本机测试的话请在hosts中进行域名绑定如 127.0.0.1  www.mysite1.com

NameVirtualHost *:8080
<VirtualHost *:8080>
ServerName www.mysite1.com
DocumentRoot "D:\Program Files\Apache2.2\htdocs"
</VirtualHost>

<VirtualHost *:8080>
ServerName www.mysite2.com
DocumentRoot "D:\Code\MySite"
</VirtualHost>

配置好后，重启apache服务，浏览器输入www.mysite1.com:8080，就会自动定向到D:\Program Files\Apache2.2\htdocs站点了

输入www.mysite2.com:8080就会自动定向到D:\Code\MySite站点，如此就可以实现在一个服务器上同时运行多个站点
