Virtual Web host

Run multiple Web sites on the same server, each of which is not independent
Take up a real computer

Types of virtual hosts supported by httpd

1. Domain name based virtual host
2. Virtual host based on IP address
3. Port based virtual host

Demonstration of examples

Domain name based virtual host

Step 1: environment deployment

1. Install DNS package bind and httpd services to test

[root@localhost ~]# yum install bind httpd -y           
...

2. Provide domain name resolution for virtual host

[root@localhost ~]# vim /etc/named.conf / / enter the main configuration file
options {
        listen-on port 53 { any; };         //Replace the original 127.0.0.1 with any
        ...
         allow-query     { any; };              //Replace localhost with any

[root@localhost ~]# vim /etc/named.rfc1912.zones / / enter the zone configuration file

zone "accp.com" IN {                                                    //First forward domain name
type master;                            
        file "accp.com.zone";                                           //Point to the area data configuration file accp.com.zone
        allow-update { none; };
};      
zone "kgc.com" IN {                                                 //Second forward domain name
        type master;
        file "kgc.com.zone";                                        //Point to the zone data configuration file kgc.com.zone
        allow-update { none; };
};

[root@localhost ~]# cd /var/named / / / enter the / var/named / directory
[root@localhost named]# cp -p named.localhost accp.com.zone / / copy the template file named.localhost as the area data configuration file of accp.com.zone.

[root@localhost named]# vim accp.com.zone / / edit the zone data configuration file

$TTL 1D
@       IN SOA  @ rname.invalid. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        NS      @
        A       127.0.0.1
www IN  A       192.168.235.129                                     //Add resolution A record and point to the IP address of this host

[root@localhost named]# cp -p accp.com.zone kgc.com.zone / / copy the zone data configuration file whose accp.com.zone is kgc.com.zone, without modification.

[root@localhost named]# systemctl start named / / start the domain name resolution service
[root@localhost named]# systemctl stop firewalld.service / / turn off the firewall
[root@localhost named]# setenforce 0 / / turn off enhanced security

Step 2: use the client to test the DNS Service

1. Modify the DNS server address of the client to the address of the virtual host.

2. Open the cmd command prompt of the client and use the nslookup command plus the domain name to obtain the resolved address.

Step 3: set related configuration files of virtual host

1. Configure the configuration file of the virtual host

[root@localhost named]# cd /etc/httpd/conf / / enter the conf directory of the configuration file
[root@localhost conf]# mkdir extra / / create an extension directory
[root@localhost conf]# cd extra / / / enter the directory
[root@localhost extra]# vim vhost.conf / / edit the virtual host configuration file. You can define it yourself.

<VirtualHost *:80>              //Label * all ip 80 ports     
DocumentRoot "/var/www/html/accp/"  //Site directory  
ServerName www.accp.com         //Site domain name
ErrorLog "logs/www. accp.com.error_log"     //Site error log file, logs is the soft link (relative path) of / var/log/httpd
CustomLog "logs/www.accp.com.access_1og" common     //Site access log
<Directory "/var/www/html/">        //Control directory permissions
Require all granted         //Allow all access
</Directory>
</VirtualHost>

<VirtualHost *:80>
DocumentRoot "/var/ www/ html/kgc/"
ServerName www. kgc. com
ErrorLog "logs/www.kgc.com.error_1og"
CustomLog "logs/www.kgc.com.access_log" common
<Directory "/var/www/html/">
Require all granted
</Directory>
</VirtualHost>

2. Configure web page

[root@localhost extra]# cd /var/www/html / / / enter the site directory
[root@localhost html]# mkdir accp kgc
[root@localhost html]# cd accp/
[root@localhost accp]# vim index.html
<h1>this is accp web</h1>

[root@localhost accp]# cd ../kgc/
[root@localhost kgc]# vim index.html
<h1>this is kgc web</h1>

3. Enter httpd.conf configuration file and declare that it contains the virtual host sub configuration file created previously

[root@localhost kgc]# cd /etc/httpd/conf        
[root@localhost conf]# vim httpd.conf 
...
Include conf/extra/vhost.conf               //Access this entry at the last line to declare that the virtual host sub configuration file is included

[root@localhost extra]# systemctl start httpd / / start httpd service

Step 4: use the client to access the web page

II. Port based virtual host

1. Edit the virtual host configuration file

[root@localhost extra]# vim vhost.conf         
...                     //Omit part of the previously set configuration
<VirtualHost  *:8080>           //Add port 8080 of accp domain name
DocumentRoot "/var/www/html/accp02"
ServerName www.accp.com
ErrorLog "logs/www.accp02.com.error_log"
CustomLog "logs/www.accp02.com.access_log" common
<Directory "/var/www/html/">
Require all granted
</Directory>
</VirtualHost>

2. Create a new 8080 port web site

[root@localhost extra]# cd /var/www/html/ 
[root@localhost html]# mkdir accp02
[root@localhost html]# cd accp02/
[root@localhost accp02]# vim index.html
<h1>this is accp02 test web</h1>

3. Modify the listening address of httpd.conf configuration file

vim /etc/httpd/conf/httpd.conf      //Enter profile
...
Listen 192.168.235.129:80           
Listen 192.168.235.129:8080         //Find the Listen entry and add the 8080 port listener
[root@localhost accp02]# systemctl restart httpd / / restart the service

4. Use client web page

III. IP based virtual host

1. First add a second network card, and then it will automatically get an IP address.

2. Configure the configuration file of the virtual host

[root@localhost accp02]# cd /etc/httpd/conf/extra/
[root@localhost extra]# ls
vhost.conf
[root@localhost extra]# vim vhost.conf

  1 <VirtualHost 192.168.235.129:80>
  2 DocumentRoot "/var/www/html/accp/"
  3 ServerName www.accp.com
  4 ErrorLog "logs/www.accp.com.error_log"
  5 CustomLog "logs/www.accp.com.access_1og" common
  6 <Directory "/var/www/html/">
  7 Require all granted
  8 </Directory>
  9 </VirtualHost>
 10 
 11 <VirtualHost  192.168.235.142:80>
 12 DocumentRoot "/var/www/html/accp02"
 13 ServerName www.accp.com
 14 ErrorLog "logs/www.accp02.com.error_log"
 15 CustomLog "logs/www.accp02.com.access_log" common
 16 <Directory "/var/www/html/">
 17 Require all granted
 18 </Directory>
 19 </VirtualHost>
