# Infra Servers-DHCP서버 설치
TASK DESCRIPTION
Network VM에 DHCP서버를 설치합니다.
DHCP는 bootstrap, master, worker node의 MAC주소와 IP를 고정하기 위해 사용됩니다.
# DHCP서버 설치
Terminal 또는 ssh명령으로 Network VM을 접근합니다.
$ yum install -y dhcp*
# DHCP설정
$ cd /etc/dhcp
$ vi dhcpd.conf
SAMPLE
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.example
# see dhcpd.conf(5) man page

TIP
위 sample로 파일을 만든 후 아래와 같이 문자열을 일괄 변경할 수 있습니다.
$ sed -i'' "s/<대상 문자열>/<바꿀 문자열>/g" <파일경로>
예) sed -i'' "s/darumtech.net/kubepia.com/g" ./dhcpd.conf
- router IP, DNS IP, base domain을 지정합니다.
- bootstrap, master, worker node의 MAC주소와 IP를 지정합니다.
ETHERNET ADAPTOR HARDWARE ADDRESS REQUIREMENTS
반드시 아래 범위의 MAC Address를 지정해야 합니다.
00:05:69:00:00:00 to 00:05:69:FF:FF:FF
00:0c:29:00:00:00 to 00:0c:29:FF:FF:FF
00:1c:14:00:00:00 to 00:1c:14:FF:FF:FF
00:50:56:00:00:00 to 00:50:56:FF:FF:FF
# DHCP서버 시작
DHCP서버를 부팅시 자동 시작하도록 등록
$ systemctl enable dhcpd
DHCP서버 시작
$ systemctl start dhcpd
상태확인
$ systemctl status dhcpd
