Install and configure the DNS server on centos7

Preparations (assuming the name is bigcloud. Local)

# Change host name # vi/etc/sysconfig/Network # Created by anacondanetworking = yeshostname = bigcloud. local # modify the file/etc/hosts with the following content: 127.0.0.1 localhost. localdomain localhost4 localhost4.localdomain4: 1 localhost. localdomain localhost6 localhost6.localdomain6192.168.188.135 bigcloud. localdomain # modify DNS configuration # vi/etc/resolv. add the following dns1 = 192.168.188.11dns2 = 192.168.188.12domain = bigcloud. local installation of bindrpm-uvh bind-9.9.4-14.el7.x86_64.rpm

Start configuring the server
