Contents 1 FQDN 정리 1.1 /etc/resolve.conf 2 /etc/hosts 2.1 ec2에서는

FQDN 정리

• hostname -f 하면 나옴

/etc/resolve.conf

• nameserver : Name server IP address
• domain : local domain name / 이 도메인 내의 호스트의 경우, 짧게 써도 된다
• search : search list for host-name lookup / 일반적으로 local domain name으로 결정됨
• domain과 search는 mutually exclusive이다. 중복해서 나오면, 마지막에 써진 넘이 적용됨

/etc/hosts

ec2에서는

• elastic ip를 쓰더라도, instance가 꺼지면 mapping이 없어짐. 다시 연결해줘야함
• /etc/init.d/networking restart
• tcping ec2-174-129-24-92.compute-1.amazonaws.com 22
  • ping 대신 사용
