http實現虛擬主機的配置

虛擬主機的介紹

    虛擬主機，簡單的說指一個物理機服務多個站點，每一個站點可經過一個或多個虛擬主機來實現

    http有3中類型的虛擬主機：

     （1）基於IP,配置時必定要配置好因此的IP

     （2）基於PORT，配置時必定要啓用Listen PORT這一項，開啓全部的監聽端口

     (3)基於FQDN，配置時要啓用NameVirtualHost這一項

相關配置

配置前提：

    已經安裝好httpd服務器

配置步驟：

1.      基於端口的虛擬主機配置

 

#vim/etc/httpd/conf/httpd.conf
…..添加以下內容………..
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 –pv
[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 –t
[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  ]

到這裏咱們基於端口的虛擬主機就配置完成，如今在瀏覽器中輸入：

http://192.168.1.11:8080/

http://192.168.1.11:80/

觀察測試結果

2.      基於FQDN的虛擬主機的配置

編輯配置文件，具體內容以下：

NameVirtualHost 192.168.1.11:80   #啓用NameVirtualHost 這一項
……….
<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

 

基於FQDN的虛擬主機配置完畢，下面進行訪問測試：

[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.      基於IP的虛擬主機配置

[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  ]

        

到這裏咱們基於IP的虛擬主機就配置完了，在瀏覽器中測試輸入：

http://192.168.1.199/

http://192.168.1.101/

 

1. 4.      基於IP+PORT的虛擬主機的配置

   

編輯配置文件/etc/httpd/conf/httpd.conf:
    Listen 8080  #添加這一項
   ……………..
      <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

到這裏咱們基於IP+PORT的虛擬主機就配置完成了，在瀏覽器中訪問192.168.1.199:80,192.168.1.101:80，192.168.1.101:8080測試，觀察結果
