서버는 방화벽이 있어야겠지.. 설치해보자 centos7부터는 firewalld라고 함.

*참고 yum erase firewalld 패키지 삭제 몇번 지웠다 깔았다 해봐야됨..

/*----------------------------------------------------------------------------------------------------------------------*/

웹서버를 만드는 중이니 정책을 넣어야징 firewall-cmd로 정책 설정 가능

아파치 구동을 위해서는 80번포트를 사용하는걸로.. 그럼 시작

*참고 firewall-cmd  --permanent 옵션은 서버재부팅/방화벽 재시작 시에도 적용되도록하는 옵션

/*----------------------------------------------------------------------------------------------------------------------*/

[root@localhost ~]# systemctl start firewalld.service <-(방화벽구동)

[root@localhost ~]# firewall-cmd --state <-(상태확인)
running <-(작동하고있네)

[root@localhost ~]# firewall-cmd --list-all <-(현재 정책을 보여줌)
public (default)
  interfaces:
  sources:
  services: dhcpv6-client ssh
  ports:
  masquerade: no
  forward-ports:
  icmp-blocks:
  rich rules:

[root@localhost ~]# firewall-cmd --add-port=80/tcp --permanent<-(아파치 실행을 위한 80번포트 개방)
success

[root@localhost ~]# firewall-cmd --reload <-(설정후 정책 다시 불러오기. 해주는게 좋음.)
success


[root@localhost ~]# firewall-cmd --list-all
