在Apache2.2.23上通过httpd.conf配置虚拟主机

   虚拟主机不要放在一个共同的端口，否则默认情况下只进入每一个虚拟主机目录。

    ServerRoot "/var/lib/apache2.2"

    DocumentRoot "/var/lib/apache2.2/htdocs"

    ErrorLog "logs/error_log"

    # apache 解析 .php 文件
   
        SetHandler application/x-httpd-php
   

    # myproject.com

    Listen 192.168.55.9:80

   
         DocumentRoot /var/lib/apache2.2/htdocs/myproject
         ServerName myproject.com
         # ScriptAlias /cgi-bin/ "/var/lib/apache2.2/htdocs/myproject/cgi-bin/"
   

  
    # myproject1.com

   Listen 192.168.55.9:81

   
         DocumentRoot /var/lib/apache2.2/htdocs/myproject1
         ServerName myproject1.com
         # ScriptAlias /cgi-bin/ "/var/lib/apache2.2/htdocs/myproject1/cgi-bin/"
   

   而我们在客户端的hosts文件里面也需要做IP映射，即：

   192.168.55.9 myproject.com

   192.168.55.9  myproject1.com

    但是我们不需要在服务器端的hosts里面做IP映射。

   实际上我们做请求时，还是用80端口来响应。

    经测试，上面这种做法存在一个问题：即使是通过 myproject1.com 来访问，进入的还是 myproject.com 。

    改为下面的可正常跳转：

    ServerRoot "/var/lib/apache2.2"

    DocumentRoot "/var/lib/apache2.2/htdocs"

    ErrorLog "logs/error_log"
   
        SetHandler application/x-httpd-php
   

    NameVirtualHost *:80

    Listen 192.168.55.9:80

    # myproject.com  

   
         DocumentRoot /var/lib/apache2.2/htdocs/myproject
         ServerName myproject.com
         # ScriptAlias /cgi-bin/ "/var/lib/apache2.2/htdocs/myproject/cgi-bin/"
   

    # myproject1.com

   
         DocumentRoot /var/lib/apache2.2/htdocs/myproject1
         ServerName myproject1.com
         # ScriptAlias /cgi-bin/ "/var/lib/apache2.2/htdocs/myproject1/cgi-bin/"
