关于ubuntu下lamp环境的配置，在ubuntu下如何配置lamp环境一文中，笔者提到了如何配置，但是没有说明如何配置多站点，导致了好多人都问笔者，这里，刚好今天有时间，就发布出来了，

首先，进入apache的配置文件，

 /etc/apache2/

目录下，然后打开ports.conf

PS:因为笔者是在虚拟机下进行的测试，所以配置的是不同端口的，如果是在服务器上测试，就不需要处理这一步了，直接跳过

# If you just change the port or add more ports here,you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

NameVirtualHost *:80
NameVirtualHost *:8080
NameVirtualHost *:8090
Listen *:80
Listen *:8080
Listen *:8090

<IfModule mod_ssl.c>
 # If you add NameVirtualHost *:443 here,you will also have to change
 # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
 # to <VirtualHost *:443>
 # Server Name Indication for SSL named virtual hosts is currently not
 # supported by MSIE on Window s XP.
 Listen 443
</IfModule>

<IfModule mod_gnutls.c>
 Listen 443
</IfModule>

添加你需要的端口，然后保存，在打开httpd.conf配置文件，

这个是一个空白的文件，然后添加如下代码：

<VirtualHost *:8090>
DocumentRoot "/usr/www/demo"
<Directory "/usr/www/demo">
allow from all
Options +Indexes
</Directory>
</VirtualHost>

然后重启apache，然后在浏览器中输入http://localhost:8090就可以看到效果了，
