Realize DNS master-slave domain, http virtual host and user
DNS domain name resolution is a service that points domain names to website space IP so that people can easily access websites through registered domain names. IP address is a digital address that identifies a site on the network. For convenience of memory, domain names are used instead of IP addresses to identify site addresses. Domain name resolution is the process of converting domain names into IP addresses. Domain name resolution is done by DNS servers.
1. Install DNS Server
[root@localhost ~]# yum -y install bind*
2. Modify the configuration file
In/etc/named.conf:
listen-on port 53 { any; }; allow-query { any; };
Then create a resolution:
vim /etc/named.rfc1912.zones
zone "web1.com" IN { type master; file "data/web1.com.zone"; };
Create web1.com.zone file in/var/named/data/as follows
$TTL 3H@ IN SOA web1.com. root ( 20180928 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum IN NS @ IN A 192.168.159.130www IN A 192.168.159.130
3. Start the named service:
systemctl start namedps -ef |grep named shows successful startup
4 test
[root@localhost ~]# nslookup > web1.comServer: 192.168.159.130Address: 192.168.159.130#53Name: web1.comAddress: 192.168.159.130
5. dns slave domain settings
vim /etc/named.rfc1912.zoneszone "web1.com" IN { type slave; file "slaves/web1.com.zone"; masters { 192.168.159.130;};};
After restarting the service:
[root@localhost ~]# nslookup > web1.comServer: 192.168.159.131Address: 192.168.159.131#53Name: web1.comAddress: 192.168.159.130HTTP
1 Installing HTTP Services
yum -y install httpd
2. Edit profile to create two virtual hosts
vim /etc/httpd/conf/httpd.conf
ServerAdmin webmaster@dummy-host.example.com DocumentRoot /var/www/html/host1/ ServerName 192.168.159.130 ErrorLog logs/dummy-host.example.com-error_log CustomLog logs/dummy-host.example.com-access_log common ServerAdmin webmaster@dummy-host.example.com ServerAdmin webmaster@dummy-host.example.com DocumentRoot /var/www/html/host1/ ServerName 192.168.159.130 ErrorLog logs/dummy-host.example.com-error_log CustomLog logs/dummy-host.example.com-access_log common
3. Add an address
ip addr add 192.168.159.129 dev ens33
4 Edit Home File
[root@localhost conf]#cat/var/www/html/vhost1/index.html [root@localhost conf]#cat/var/www/html/host1/index.html
