XAMPP3.1.0中Apache2.4.3的多站点配置(vhost/virtual host)

最近想在Apache2.4.3上挂载多站点，可是怎么都不成功。我使用的是同一个IP、不同名字的方法（也叫Name-Based方法，另外一种方法叫IP-Based）。也就说本机IP都是127.0.0.1，但是访问localhost、www.a.com、www.b.com时，所指向的网站目录不同。

最终要实现的指向是：

127.0.0.1 ==> D:/xampp/htdocs/xampp

localhost ==> D:/xampp/htdocs/xampp

www.a.com ==> D:/xampp/htdocs/a

www.b.com ==> D:/xampp/htdocs/b

（有人可能会问，能不能指向“xampp/htdocs”以外的目录，比如G:/website/a。这个应该得修改httpd.conf中的DocumentRoot。可修改后，浏览127.0.0.1和localhost就不会指向xampp/htdocs/xampp了。如果不修改原有的DocumentRoot，只仅仅添加Dirctory，我试了网上各种添加方法，都没成功。可能是版本原因。所以在文章标题处特地注明了我所使用的版本。所以，为了效果好、方便，还是把站点都放在xampp/htdocs下吧。）

1.修改C:\Windows\System32\drivers\etc下的hosts文件：

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
	127.0.0.1       localhost
	127.0.0.1	www.a.com
	127.0.0.1	www.b.com
#	::1             localhost

2.在D:\xampp\htdocs中新建目录/a/、/a/logs/、/b/、/b/logs/

3.修改D:\xampp\apache\conf\extra下的httpd-vhost.conf：

#
# 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>
    ##ServerAdmin postmaster@dummy-host.localhost
    ##DocumentRoot "D:/xampp/htdocs/dummy-host.localhost"
    ##ServerName dummy-host.localhost
    ##ServerAlias www.dummy-host.localhost
    ##ErrorLog "logs/dummy-host.localhost-error.log"
    ##CustomLog "logs/dummy-host.localhost-access.log" combined
##</VirtualHost>

##<VirtualHost *:80>
    ##ServerAdmin postmaster@dummy-host2.localhost
    ##DocumentRoot "D:/xampp/htdocs/dummy-host2.localhost"
    ##ServerName dummy-host2.localhost
    ##ServerAlias www.dummy-host2.localhost
    ##ErrorLog "logs/dummy-host2.localhost-error.log"
    ##CustomLog "logs/dummy-host2.localhost-access.log" combined
##</VirtualHost>

# 挂载多站点
#配置回原localhost，不然原localhost的访问会出错
<virtualhost *:80>
ServerName localhost
DocumentRoot "D:/xampp/htdocs"
</virtualhost>

#添加站点1
<virtualhost *:80>
ServerName www.a.com
DocumentRoot "D:/xampp/htdocs/a/"
ErrorLog "D:/xampp/htdocs/a/logs/www.a.com.log"
CustomLog "D:/xampp/htdocs/a/logs/www.a.com.log" combined
</virtualhost>

#添加站点2
<virtualhost *:80>
ServerName www.b.com
DocumentRoot "D:/xampp/htdocs/b/"
ErrorLog "D:/xampp/htdocs/b/logs/www.b.com.log"
CustomLog "D:/xampp/htdocs/b/logs/www.b.com.log" combined
</virtualhost>

Apache2.4.x可不用NameVirtualHost *:80，官网也不推荐使用。使用了在error.log中反而会出现警告“AH00548: NameVirtualHost has no effect and will be removed in the next release D:/xampp/apache/conf/extra/httpd-vhosts.conf:46”。

4.保存文件，重启Apache即可。
