Deployment of virtual host function based on Apache service

If only one website can run on the server of each Linux system, this obviously results in a waste of hardware resources.

By using the virtual host function, a physical server can be divided into multiple "virtual servers" to save resources and avoid waste.

The virtual host function of Apache is based on different IP addresses, host domain names or port numbers requested by users to provide access services for multiple websites at the same time.

Let's explain the implementation method in detail.

This experiment is based on cenos7 to build Apache httpd-2.4.6.

Install first

[root@lin10 ~] # yum install httpd-y

Since I need to implement this experiment based on different IP, I added three different IP

The ens33 card of this linux was originally 172.16.16.1 IP 16, so add two other CPUs to implement three different CPUs.

[root@localhost ~] # ip addr add 172.16.16.2Universe 16 dev ens33

[root@localhost ~] # ip addr add 172.16.16.3 Universe 16 dev ens33

Turn off Firewall systemctl disable firewalld

Close selinux vi / etc/sysconfig/selinux

Modify SELINUX=enforcing to disabled

One based on IP address

1 create three directories to store the data of different websites in / opt/www, and write the home page file to them.

Mkdir-p / opt/www/1

Mkdir-p / opt/www/2

Mkdir-p / opt/www/3

Echo "172.16.16.1" > / opt/www/1/index.html

Echo "172.16.16.2" > / opt/www/2/index.html

Echo "172.16.16.3" > / opt/www/3/index.html

2 start at about 113th line in the configuration file of httpd service, append and write three virtual host website parameters based on IP address respectively, then save and exit. Remember that you need to restart the httpd service for these configurations to take effect.

Vim / etc/httpd/conf/httpd.conf

one hundred and thirteen

114 DocumentRoot / opt/www/1

115 ServerName www.wawa.com

one hundred and sixteen

117 AllowOverride None

118 Require all granted

one hundred and nineteen

one hundred and twenty

one hundred and twenty one

122 DocumentRoot / opt/www/2

123 ServerName bbs.wawa.com

one hundred and twenty four

125 AllowOverride None

126 Require all granted

one hundred and twenty seven

one hundred and twenty eight

one hundred and twenty nine

130 DocumentRoot / opt/www/3

131 ServerName test.wawa.com

one hundred and thirty two

133 AllowOverride None

134 Require all granted

one hundred and thirty five

one hundred and thirty six

Don't forget to monitor port 80.

At this point, the virtual host function based on IP can be implemented, start the service and verify.

Second, based on port number

I was lazy and directly modified the previous IP-based configuration file to achieve a virtual host based on the port number.

Based on the three ports 80 8080 and 6111

Vim / etc/httpd/conf/httpd.conf

Listening port needs to be adjusted

Verify:

Based on host domain name

Based on the fact that the host domain name requires dns resolution to achieve this operation, the specific actions are not listed here (click).

It's the same as usual. I'll use the previous file to modify it.

Change the listening port to 80

Vim / etc/httpd/conf/httpd.conf
