binding server 에 도메인 등록하기

# 도메인 추가시에 bind server configuration 에 대하여 알아봅니다.

.일단 서버에 bind 서버가 깔려있는지를 알아봅니다.
 버젼을 확인해 봅니다.(rpm의 경우)

> rpm -qa bind*
bind-libs-9.3.3-9.0.1.el5
bind-utils-9.3.3-9.0.1.el5
bind-9.3.3-9.0.1.el5
bind-chroot-9.3.3-9.0.1.el5

안되어 있다면 설치를 합니다.(설치는 생략합니다.)

.설정파일에 추가된 도메인을 설정합니다.
> cd /var/named/chroot/etc
> vi named.conf
……
zone “[first.co.kr]” {
        type master;
        file “[first.comt.zone]“;
        allow-update { none; };
};
zone “[second.com]” {
        type master;
        file “[first.comt.zone]“;
        allow-update { none; };
};
zone “[third.com]” {
        type master;
        file “[first.comt.zone]“;
        allow-update { none; };
};
* [] 부분을 통째로 자기 환경에 맞게 수정하여야 합니다.

.서브도메인을 구성할 경우에는 domain.zone 파일(first.comt.zone) 을 수정합니다.
.named 데몬을 재구동 합니다.
