Build a virtual host virtual Web host:

1. Run multiple Web sites in the same physical server, each of which does not independently occupy a real computer

Virtual host types supported by httpd:

1. Domain name-based virtual host (commonly used by enterprises)

two。 Virtual host based on IP address

3. Port-based virtual host

Large company example project:

Two physical hosts (ABG B)

There are two virtual sites in each of the two hosts

There are accp sites and kgc sites in hosts An and B.

The content of the website is exactly the same, and when providing business to the outside world, it not only uses a reasonable distribution, but also plays a dual hot standby.

Learn the architecture of one host and two websites

one。 Build a virtual host-an example of a domain name-based application:

1. Build 2 virtual Web sites

Www.kgc.com, IP address is 173.17.17.11

Www.kcce.com, IP address is 173.17.17.11

two。 When the two domain names are accessed in the browser, different contents are displayed.

Provide domain name resolution for virtual hosts: [root@dnssvr ~] # vim / var/named/chroot/var/named/kgc.com.zone@ IN NS dnssvr.kgc.com.dnssvr IN A 173.17.1 7.2www IN A 173.17.17.11 [root@dnssvr ~] # vim / var/named/chroot/var/named/kcce.com.zone@ IN NS dnssvr.kgc.com.www IN A 173.17.17.11 Prepare web documents for virtual hosts: [root@www ~] # mkdir-p / var/www/html/kgccom [root@www ~] # mkdir-p / var/www/html/kccecom [root@www ~] # echo "www.kgc.com" > / var/www/html/kgccom/index.html [root@www ~] # echo "www.kcce.com" > / var/www/html/kccecom/index.html add virtual host configuration: [root@www ~] # vim / usr/local/httpd/conf/extra/httpd-vhosts.conf DocumentRoot "/ var/www/html/kgccom" ServerName www.kgc.com ErrorLog "logs/www.kgc.com.error_log" CustomLog "logs/www.kgc.com.access_log" common

Require all granted DocumentRoot "/ var/www/html/kccecom" ServerName www.kcce.com accesses the virtual Web host Demo1 on the client respectively: access the virtual host based on the domain name, add the second network card to the virtual machine settings, and display:

The above is the way to access the virtual host based on the domain name

two。 Build a virtual host-example of a port-based application:

1. Build two virtual Web sites

Www.kcce.com, the address and port of IP is 173.17.17.11 virtual 80

Www.kcce.com, the address and port of IP is 173.17.17.11

two。 When accessing the two ports in the browser, different contents are displayed.

[root@www ~] # vim / usr/local/httpd/conf/extra/httpd-vhosts.conf

DocumentRoot "/ var/www/htm/kccecom" ServerName www.kcce.com DocumentRoot "/ var/www/htm/kccepad" ServerName www.kcce.comListen 80Listen 835 listening ports are written in the main configuration file Demo2: access based on different ports [root@localhost extra] # vim vhost.conf DocumentRoot "/ var/www/html/kgc02/" ServerName www.kgc.com ErrorLog "logs/www.kgc02.com.error_log" CustomLog "logs/www.

Input: wq save and exit [root@localhost kgc02] # systemctl restart httpd / / restart the service [root@localhost kgc02] # netstat-ntapActive Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0 0. 0 systemctl restart httpd 111 0.0.0 0 * LISTEN 1/systemd Tcp 0 0 192.168.56.131 LISTEN 52732/httpd # you can see that both ports are listening at this time. * LISTEN 52732/httpd tcp 0 192.168.56.131 LISTEN 52732/httpd #

Verify: use win7's browser, enter: www.kgc.com:8080

What is displayed at this time is the home page of the 8080 port kgc02 that we wrote in advance.

If you type: www.kgc.com:80, the interface of this is kgc web is also displayed.

This is the port-based way to access the virtual host

Demo3: access based on different IP

Previously, we had two network cards with addresses of 192.168.56.131 and 192.168.56.134, which need to be used here.

[root@localhost kgc02] # cd / etc/httpd/conf/extra/ [root@localhost extra] # lsvhost.conf [root@localhost extra] # vim vhost.conf//11,29 s / ^ / # / g / / comment lines 11 to 29 globally You do not need to use / / here to change the * number to the IP DocumentRoot "/ var/www/html/accp/" ErrorLog "logs/www.accp.com.error_log" CustomLog "logs/www.accp.com.access_log" common Require all granted / / change the * number to the IP of the second network card here.
