Apache配置基于端口号的虚拟主机 Apache virtual host configuration is based on the port

有可能只有一个ip出口，但却有多个项目，那么就需要基于端口号架设虚拟主机。

Step 1：

　　检查是否开启 httpd-vhosts.conf

　　apache/conf/httpd.conf文件

# Virtual hosts
Include conf/extra/httpd-vhosts.conf

　　如果没有开启，必须在httpd.conf文件中设置；如果开启，则可以在apache/conf/extra/httpd-vhosts.conf文件中设置，当然也还是可以再httpd.conf文件中进行设置，同样有效。

Step 2：

　　httpd.conf文件 DocumentRoot一定要是要配置成虚拟主机的项目的父级目录，此处的DocumentRoot限制的级别最高，虚拟主机中设置的DocumentRoot目录级别只能等于或低于此处的DocumentRoot目录。

# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "D:\htdocs"
<Directory "D:\htdocs">

Step 3：

　　httpd.conf文件中添加多端口监听。

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 80
Listen 81
Listen 82

Step 4：

　　按照Step1中的规则，添加虚拟主机配置。

<VirtualHost *:80>
    DocumentRoot "D:\htdocs\project1\www"
    ServerName 127.0.0.1:80
    <Directory "D:\htdocs\project1\www">
        Options Indexes FollowSymLinks Multiviews
        AllowOverride All
        Order Allow,Deny
        Allow from all
    </Directory>
</VirtualHost>
<VirtualHost *:81>
    DocumentRoot "D:\htdocs\project2"
    ServerName 127.0.0.1:81
    <Directory "D:\htdocs\project2">
        Options Indexes FollowSymLinks Multiviews
        AllowOverride All
        Order Allow,Deny
        Allow from all
    </Directory>
</VirtualHost>

Note：

　　在虚拟主机配置中一定要覆盖80端口的配置，不然则使用httpd.conf中配置的DocumentRoot的目录，那么项目的上级目录则暴露了。
