방화벽 비활성

재기동 시 start 되지 않도록 비활성화 해줍니다

systemctl disable firewalld.service

반대는 systemctl enable firewalld.service

[root@svr1 ~]# systemctl disable firewalld.service
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
