Analysis of Apache's common virtual host configuration methods

1. Apache server installation and configuration

yum install httpd -y

systemctl start httpd &&systemctl enable httpd

systemctl stop firewalld

setenforce 0 //Set the selinux security level to premise and the reboot will fail.

Use the local Windows browser to test the virtual machine's IP address (be sure to turn off the firewall). If you see the following interface, it means that HTTP is successfully started.

2. Apache2 configuration file

After httpd is installed, the /etc/httpd directory will be automatically generated

Main configuration file: conf/httpd.conf

3. Based on IP address (the server requires multiple public IP addresses)

www.lyn1.com----192.168.100.135
www.lyn2.com----192.168.100.136

(1) Bind another IP address to the server

(2) Add a site file lyn1.conf in the /etc/httpd/conf.d directory

You can also configure it directly in /etc/httpd/conf/httpd.conf. The httpd.conf file will automatically import the files in /etc/httpd/conf.d. For convenience, we write it directly to the /etc/httpd/conf.d folder.

mkdir /mnt/lyn1

cd /etc/httpd/conf.d

vi lyn1.conf

<VirtualHost 192.168.100.135> //Local IP addressDocumentRoot /mnt/lyn1/ //Network data directoryServerName www.lyn1.com //Domain name of the website server<Directory /mnt/lyn1/ > //Website data directory permissionsAllowOverride None //Do not allow overwritingRequire all granted //Allow all access requests</Directory>
</VirtualHost>

(3) Add the webpage file index.html to the publishing directory of the corresponding website of shiyan1.com

vi /mnt/lyn1/index.html

<html>
<head>
<title>lyn1</title>
</head>
<body>
<h1>lyn1</h1>
this is the www.lyn1.com website
</body>
</html>

(4) Add a site file lyn2.conf in the /etc/httpd/conf.d directory

mkdir /mnt/lyn1

cd /etc/httpd/conf.d

vi lyn1.conf

<VirtualHost 192.168.100.136> //Another IP address of this machineDocumentRoot /mnt/lyn2/ //Network data directoryServerName www.lyn2.com //Domain name of the website server<Directory /mnt/lyn2/ > //Permissions for the website data directoryAllowOverride None //Do not allow overwritingRequire all granted //Allow all access requests</Directory>
</VirtualHost>

vi /mnt/lyn2/index.html

<html>
<head>
<title>lyn2</title>
</head>
<body>
<h1>lyn2</h1>
this is the www.lyn2.com website
</body>
</html>

(6) Restart the Apache server and verify using a browser

systemctl restart httpd

4. Configure virtual hosts based on port numbers

www.lyn1.com----192.168.100.135:80
www.lyn2.com----192.168.100.135:81

(1) Add listening port 81 to the main configuration file /etc/httpd/conf/httpd.conf

#vi /etc/httpd/conf/httpd.conf
Listen 80
Listen 81

(2) Modify the /etc/httpd/conf.d/lyn1.conf file:

<VirtualHost 192.168.100.135:80>
ServerName www.lyn1.com
DocumentRoot /var/www/html/lyn1/
<Directory /var/www/html/lyn1/ > 
AllowOverride None   
Require all granted  
</Directory>
</VirtualHost>

(3) Modify the /etc/httpd/conf.d/shiyan2.conf file:

<VirtualHost 192.168.100.135:81>
ServerName www.lyn2.com
DocumentRoot /var/www/html/lyn2/
<Directory /var/www/html/lyn2/ > 
AllowOverride None  
Require all granted 
</Directory>
</VirtualHost>

(4) Restart the Apache server and verify using a browser

systemctl restart httpd

5. Configure a hostname-based virtual machine

www.lyn1.com----192.168.100.135:80
www.lyn2.com----192.168.100.135:80

(1) Register DNS (configure DNS server and implement normal resolution). For temporary testing, you can use the /etc/hosts modification method. Here, the hosts modification method is used.

#vi /etc/hosts

192.168.100.135 www.lyn1.com
192.168.100.135 www.lyn2.com

(2) In the main configuration file /etc/httpd/conf.d/lyn1.conf

<VirtualHost *:80>
ServerName www.lyn1.com
DocumentRoot /var/www/html/lyn1/
<Directory /var/www/html/lyn1/ >
AllowOverride None
Require all granted
</Directory>
</VirtualHost>

(3) In the main configuration file /etc/httpd/conf.d/lyn2.conf

<VirtualHost *:81>
ServerName www.lyn2.com
DocumentRoot /var/www/html/lyn2/
<Directory /var/www/html/lyn2/ >
AllowOverride None
Require all granted
</Directory>
</VirtualHost>

(4) Restart the apache2 server and verify

systemctl restart httpd
[root@lyn html]# curl www.lyn1.com
[root@lyn html]# curl www.lyn2.com

To access a website under Windows, add the following two lines to the C:\Windows\System32\drivers\etc\hosts file

192.168.100.135 www.lyn1.com
192.168.100.135 www.lyn2.com
