centos8 http&https open port firewalld

 

기존에 centos7 방화벽 관련 설정을 이곳에 포스팅해두었다.

centos 방화벽 설정 port 80 오픈

 

 

현재 사용중인 서버는 centos8 이기 때문에 바뀐 방화벽 설정 명령을 정리해보려고 한다.

 

Step1.Check the status of your firewall.

# firewall-cmd --state
running

 

Step2. Retrieve your currently active zones. Take a note of the zone within which you wish to open ports 80 and 443:

# firewall-cmd --get-active-zones
libvirt
  interfaces: virbr0 
public
  interfaces: enp0s3

 

Step3. Open port 80 and port 443 port.

# firewall-cmd --zone=public --add-service=http
# firewall-cmd --zone=public --add-service=https

728x90

Step4. Open port 80 and port 443 port permanently. Execute the below commands to open both ports permanently, hence, make the settings persistent after reboot:

# firewall-cmd --zone=public --permanent --add-service=http
# firewall-cmd --zone=public --permanent --add-service=https
# firewall-cmd --reload

 

Step5. Check for open ports/services. The services with permanently open ports are listed on line starting with services::

# firewall-cmd --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: enp0s3
  sources: 
  services: cockpit dhcpv6-client http https ssh
  ports: 
  protocols: 
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules:

 

Step6. In case you need to close the previously open HTTP port 80 and HTTPS port 443 execute:

# firewall-cmd --zone=public --permanent --remove-service=http
# firewall-cmd --zone=public --permanent --remove-service=https
# firewall-cmd --reload
