虚拟主机分类

1、基于IP的虚拟主机
2、基于域名的虚拟主机
对于不同情况下配置apache虚拟主机的方法，一共八种情况。首先查看你虚拟主机属于哪一种情况，然后对号入座就好了。

  1. 1
    基于ip地址的虚拟主机
    Listen 80

    DocumentRoot /home/httpd/html1
    ServerName www.ok1.com
    ErrorLog /usr/local/apache/logs/error1_log
    CustomLog /usr/local/apache/logs/access1_log combined

    DocumentRoot /home/httpd/html2
    ServerName www.ok2.com
    ErrorLog /usr/local/apache/logs/error2_log
    CustomLog /usr/local/apache/logs/access2_log combined

  2. 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

    DocumentRoot /www/example1-80
    ServerName www.example1.com

    DocumentRoot /www/example1-8080
    ServerName www.example1.com

    DocumentRoot /www/example2-80
    ServerName www.example1.org

    DocumentRoot /www/example2-8080
    ServerName www.example2.org

  3. 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

    DocumentRoot /www/example1
    ServerName www.example1.com
    ServerAlias example1.com. *.example1.com
    # Other directives here

    DocumentRoot /www/example2
    ServerName www.example2.org
    # Other directives here

  4. 4
    在多个IP 地址的服务器上配置基于域名的虚拟主机
    Listen 80
    # This is the "main" server running on 172.20.30.40
    ServerName server.domain.com
    DocumentRoot /www/mainserver
    # This is the other address
    NameVirtualHost 172.20.30.50

    DocumentRoot /www/example1
    ServerName www.example1.com
    # Other directives here ...

    DocumentRoot /www/example2
    ServerName www.example2.org
    # Other directives here ...

  5. 5
    在不同的端口上运行不同的站点(基于多端口的服务器上配置基于域名的虚拟主机)
    Listen 80
    Listen 8080
    NameVirtualHost 172.20.30.40:80
    NameVirtualHost 172.20.30.40:8080

    ServerName www.example1.com
    DocumentRoot /www/domain-80

    ServerName www.example1.com
    DocumentRoot /www/domain-8080

    ServerName www.example2.org
    DocumentRoot /www/otherdomain-80

    ServerName www.example2.org
    DocumentRoot /www/otherdomain-8080

  6. 6
    基于域名和基于IP 的混合虚拟主机的配置
    Listen 80
    NameVirtualHost 172.20.30.40

    DocumentRoot /www/example1
    ServerName www.example1.com

    DocumentRoot /www/example2
    ServerName www.example2.org

    DocumentRoot /www/example3
    ServerName www.example3.net
