14. Three virtual hosts and 14 three virtual hosts

A vm provides Web Services for multiple individual domain names on a WWW server.

Apache supports Virtual Hosts in three ways:

1. IP-based VM:Multiple IP addresses are configured on one server. Each IP Address has a specific directory and configuration. Suitable for scenarios with sufficient IP addresses

1、[root@localhost root]#   vi  /etc/named.conf
zone "gr.org" IN {        type master;        file "gr.org.db";        allow-update { none; };};zone "170.168.192.in-addr.arpa" IN {       type master;       file "170.168.192.db";};

 

2. forward regional database file
[Root @ localhost root] # vi/var/named/gr.org. db
$TTL 86400@ IN SOA  ns.gr.org.    root.gr.org.(            20140308 ;serial            8H       ;refresh            4M       ;retry            1W       ;expiry            1D  )    ;minimum@      IN   NS      ns.gr.org.ns     IN   A       192.168.170.1host1  IN   A       192.168.170.1host2  IN   A       192.168.170.2host3  IN   A       192.168.170.3
 
Reverse region database file
[Root @ localhost root] # vi/var/named/170.168.192.db
$TTL 86400@ IN SOA ns.gr.org.  root.gr.org.(                     20150826                     8H                     4M                     1W                     1D)          IN   NS     ns.gr.org.1         IN   PTR    ns.gr.org.1         IN   PTR    host1.gr.org.2         IN   PTR    host2.gr.org.3         IN   PTR    host3.gr.org.
3. Set the DNS Client
[Root @ localhost root] # cat>/etc/resolv. conf
Nameserver 192.168.170.4
Service named start (start service)
If it has been started, run the rndc reload command to restart the service)
 
4. Configure the VM
[Root @ localhost conf. d] # vi/etc/httpd/conf. d/host_ip.conf
<VirtualHost 192.168.170.1:80>    DocumentRoot /var/www/host1    ServerName   host1.gr.org</VirtualHost><VirtualHost 192.168.170.2:80>    DocumentRoot /var/www/host2    ServerName   host2.gr.org</VirtualHost><VirtualHost 192.168.170.3:80>    DocumentRoot /var/www/host3    ServerName   host3.gr.org</VirtualHost>
5. Add the IP address of the sub-interface
[Root @ localhost conf. d] # ifconfig eth0: 1 192.168.170.1
[Root @ localhost conf. d] # ifconfig eth0: 2 192.168.170.2
[Root @ localhost conf. d] # ifconfig eth0: 3 192.168.170.3
 
6. Create a VM directory and a test Homepage
Mkdir/var/www/host {1, 2, 3}
Cd/var/www
Echo "this host1"> host1/index.html
Echo "this host2"> host2/index.html
Echo "this host3"> host3/index.html
 
7. Restart the service
Service httpd restart
 
The result is as follows:
2. Port-based VM:
1. Create the host_port.conf file in the/etc/httpd/conf. d directory and add the following content:
Listen  192.168.170.1:8000Listen  192.168.170.1:8888<VirtualHost  192.168.170.1:8000>      DocumentRoot   /var/www/host4      ServerName   host1.gr.org </VirtualHost> <VirtualHost  192.168.170.2:8888>     DocumentRoot   /var/www/host5     ServerName   host1.gr.org </VirtualHost>
 
2. Create a VM working directory and test Homepage
mkdir  /var/www/host{4,5}   echo  “this host1(8000)” > /var/www/host4/index.html   echo  “this host1(8888)” > /var/www/host5/index.html
3. Restart the service
Service httpd restart
 
Test
Iii. Name-based virtual hosts (most of which are used)
Access from multiple domain names corresponds to the same IP address
1. Add the following content to the forward regional database file
music   IN  A  192.168.170.1movie   IN  A  192.168.170.1
 
2. Add the following content to the reverse regional database file
1   IN   PTR    music.gr.org.1   IN   PTR    movie.gr.org.
 
3. Create the host_domain.conf file in the/etc/httpd/conf. d directory and add the following content:
<VirtualHost   music.gr.org:80> DocumentRoot   /var/www/musicServerName   music.gr.org</VirtualHost> <VirtualHost   movie.gr.org:80> DocumentRoot   /var/www/movie ServerName   movie.gr.org</VirtualHost>
 
4. Create a VM's working directory and test Homepage
cd    /var/wwwmkdir  music  movieecho “this  music” >  music/index.htmlecho “this  movie” >  movie/index.html
 
5. Restart the service
Rndc reload or service named restart
Service httpd start
 
6. Test
