1, when installing cloudera-manager-agent, error, newspapers port 80 problem,

Turn on port 80

Firewall-cmd --zone=public --add-port=/tcp --permanent

Success appears to indicate added success

Command meaning:

--zone #作用域

--add-port=80/tcp #添加端口 in the format: Port/Communication protocol

--permanent #永久生效, fail after reboot without this parameter

Run, stop, disable FIREWALLD

Start: # systemctl start Firewalld

View Status: # Systemctl status Firewalld or Firewall-cmd--state

Stop: # systemctl Disable FIREWALLD

Disable: # Systemctl stop Firewalld

After the port is turned on normally, the CentOS 7 firewall is not iptables (not familiar to the system).
