centos 7.6 DNS——别名解析、泛域名解析、邮件交换步骤一：安装bind dns应用程序，修改主配置文件步骤二：修改区域配置文件步骤三： 区域数据配置文件

步骤一：安装bind dns应用程序，修改主配置文件

yum -y install bind[root@localhost etc]# rpm -qc bind/etc/logrotate.d/named/etc/named.conf/etc/named.iscdlv.key/etc/named.rfc1912.zones/etc/named.root.key/etc/rndc.conf/etc/rndc.key/etc/sysconfig/named/var/named/named.ca/var/named/named.empty/var/named/named.localhost/var/named/named.loopback[root@localhost etc]# vi /etc/named.conf

步骤二：修改区域配置文件

vi /etc/named.rfc1912.zones

cp -p /var/named/named.hostlocal /var/named/.zone//新建区域数据配置文件[root@localhost named]# vim /var/named/.zone [root@localhost named]# systemctl restart named[root@localhost named]# echo "nameserver 192.168.75.137" > /etc/resolv.conf //主机地址作为DNS地址，用来解析本机域名[root@localhost named]# host //解析邮件域名ip地址 has address 8.8.8.8[root@localhost named]# host has address 7.7.7.7[root@localhost named]# host //解析别名域名 is an alias for . has address 8.8.8.8[root@localhost named]# host//当输入错误的域名，泛域名地址就发挥作用 has address 6.6.6.6[root@localhost named]#

步骤三： 区域数据配置文件
