HTTP implementation of virtual host configuration

Introduction to Virtual Hosting

Virtual host, simply refers to a physical machine service multiple sites, each site through one or more virtual hosts to achieve

HTTP has 3 types of virtual hosts:

(1) IP-based, configuration must be configured so that the IP

(2) based on port, be sure to enable listen port this entry, open all the listening ports

(3) FQDN-based, when configured to enable the Namevirtualhost

Configuration Prerequisites:

The HTTPD server is already installed.

Configuration steps:

1. Port-based virtual host configuration

#vim/etc/httpd/conf/httpd.conf ... add the following content ....... Listen 8080......................<virtualhost *:80>servername www.a.comdocumentroot/vhosts/a.com/htdocs /</virtualhost> <virtualhost *:8080>servername www.b.orgdocumentroot/vhosts/b.org/ htdocs</virtualhost> # mkdir/vhosts/{a.com,b.org}/htdocs –pv[[email protected]  ~]# cd /vhosts/a.com/htdocs/[[email protected] htdocs]# vimindex.html          
Here our port-based virtual host is configured to complete, and now in the browser enter:
http://192.168.1.11:8080/
http://192.168.1.11:80/
Observing test Results

2.    FQDN -based  the configuration of the virtual host
Edit the configuration file with the following details:
namevirtualhost 192.168.1.11:80    #启用NameVirtualHost   This ..........< 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> [[ Email protected] htdocs]# mkdir/vhosts/c.net/htdocs -p[[email protected] htdocs] #vim  /vhosts/c.net/htdocs/index.html            
FQDN -based   The virtual host configuration is complete and the following access tests are performed:
[Email protected] vhosts]# curlhttp://www.c.net
[Email protected] vhosts]# curlhttp://www.b.org
[Email protected] vhosts]# curlhttp://www.a.com

Here we are based on The IP virtual host is configured, and the input is tested in the browser:
http://192.168.1.199/
http://192.168.1.101/
 
    
 
     
 
      
4.    based on Ip+port  the configuration of the virtual host
 
     
 
    
Edit configuration file/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&G T;<virtualhost 192.168.1.21:80> ServerName www.b.org Documentroot/vhosts/b.org/htdocs/</virtualhos t> <VirtualHost192.168.1.11:8080> ServerName www.c.net Documentroot/vhosts/c.net/htdocs/</virtu alhost> #httpd-t#service httpd restart

Here we are based on Ip+port Virtual Host is configured, Access 192.168.1.199:80,192.168.1.101:80 in the browser , 192.168.1.101:8080 Test, observe the results
