http实现虚拟主机的配置

虚拟主机的介绍

    虚拟主机，简单的说指一个物理机服务多个站点，每个站点可通过一个或多个虚拟主机来实现

    http有3中类型的虚拟主机：

     （1）基于IP,配置时一定要配置好所以的IP

     （2）基于PORT，配置时一定要启用Listen PORT这一项，开启所有的监听端口

     (3)基于FQDN，配置时要启用NameVirtualHost这一项

相关配置

配置前提：

    已经安装好httpd服务器

配置步骤：

1.      基于端口的虚拟主机配置

 

#vim/etc/httpd/conf/httpd.conf
…..添加如下内容………..
Listen 8080
………………….
<VirtualHost *:80>
ServerName www.a.com
DocumentRoot/vhosts/a.com/htdocs/
</VirtualHost>
 
<VirtualHost *:8080>
ServerName www.b.org
DocumentRoot/vhosts/b.org/htdocs
</VirtualHost>
 
# mkdir/vhosts/{a.com,b.org}/htdocs �Cpv
[root@node1 ~]# cd /vhosts/a.com/htdocs/
[root@node1 htdocs]# vimindex.html
         <h1>a.com</h1>
[root@node1 htdocs]#vim /vhosts/b.org/htdocs/index.html
           <h1>b.org</h1>
#vim /etc/hosts
…………添加
192.168.1.11 www.a.com
192.168.1.12 www.b.org
#httpd �Ct
[root@node1 htdocs]# service httpd restart
Stopping httpd:                                            [ OK  ]
Starting httpd: httpd:Could not reliably determine the server's fully qualified domain name, using172.16.33.1 for ServerName
                                                          [  OK  ]

到这里我们基于端口的虚拟主机就配置完成，现在在浏览器中输入：

http://192.168.1.11:8080/

http://192.168.1.11:80/

观察测试结果

2.      基于FQDN的虚拟主机的配置

编辑配置文件，具体内容如下：

NameVirtualHost 192.168.1.11:80   #启用NameVirtualHost 这一项
……….
<VirtualHost192.168.1.11:80>
        ServerName www.a.com
        DocumentRoot /vhosts/a.com/htdocs/
</VirtualHost>
 
<VirtualHost192.168.1.11:80>
        ServerName www.b.org
        DocumentRoot /vhosts/b.org/htdocs
</VirtualHost>
<VirtualHost192.168.1.11:80>
        ServerName www.c.net
        DocumentRoot /vhosts/c.net/htdocs
</VirtualHost>
 
[root@node1 htdocs]# mkdir/vhosts/c.net/htdocs -p
[root@node1 htdocs]#vim /vhosts/c.net/htdocs/index.html
           <h1>c.net</h1>
 
[root@node1 vhosts]# vim/etc/hosts
……添加…..
192.168.1.11 www.a.com
192.168.1.11 www.b.org
192.168.1.11 www.c.net

 

基于FQDN的虚拟主机配置完毕，下面进行访问测试：

[root@node1 vhosts]# curlhttp://www.c.net

<h1>c.net</h1>

[root@node1 vhosts]# curlhttp://www.b.org

<h1>b.org</h1>

[root@node1 vhosts]# curlhttp://www.a.com

<h1>a.com</h1>

 

1. 3.      基于IP的虚拟主机配置

[root@node1 vhosts]#ifconfig eth0:0 192.168.1.21
[root@node1 vhosts]# vim/etc/httpd/conf/httpd.conf
………..
<VirtualHost192.168.1.11:80>
        ServerName www.a.com
        DocumentRoot /vhosts/a.com/htdocs/
</VirtualHost>
<VirtualHost192.168.1.21:80>
        ServerName www.b.org
        DocumentRoot /vhosts/b.org/htdocs/
</VirtualHost>
[root@node1 vhosts]# httpd-t
httpd: Could not reliablydetermine the server's fully qualified domain name, using 172.16.33.1 forServerName
Syntax OK
[root@node1 vhosts]# !s
service httpd restart
Stopping httpd:                                           [  OK  ]
Starting httpd: httpd:Could not reliably determine the server's fully qualified domain name, using172.16.33.1 for ServerName
                                                          [  OK  ]

        

到这里我们基于IP的虚拟主机就配置完了，在浏览器中测试输入：

http://192.168.1.199/

http://192.168.1.101/

 

1. 4.      基于IP+PORT的虚拟主机的配置

   

编辑配置文件/etc/httpd/conf/httpd.conf:
    Listen 8080  #添加这一项
   ……………..
      <VirtualHost192.168.1.11:80>
        ServerName www.a.com
        DocumentRoot /vhosts/a.com/htdocs/
</VirtualHost>
<VirtualHost 192.168.1.21:80>
        ServerName www.b.org
        DocumentRoot /vhosts/b.org/htdocs/
</VirtualHost>
 
<VirtualHost192.168.1.11:8080>
        ServerName www.c.net
        DocumentRoot /vhosts/c.net/htdocs/
</VirtualHost>
 
#httpd -t
#service httpd restart

到这里我们基于IP+PORT的虚拟主机就配置完成了，在浏览器中访问192.168.1.199:80,192.168.1.101:80，192.168.1.101:8080测试，观察结果
