1. Configure the firewall:

Either turn off the firewall or join the release port

1.1 Turn off the firewall directly###

systemctl stop firewalld.service #Stop firewall
systemctl disable firewalld.service #Prohibit firewall startup
firewall-cmd --state #View the default firewall status (notrunning will be displayed after it is turned off, and running)

[ root@localhost ~]# firewall-cmd --state
not running
[ root@localhost ~]#

1.2 Add release port###

firewall-cmd --zone=public--add-port=80/tcp --permanent #Add release port(--permanent takes effect permanently, it will become invalid after restart without this parameter)

firewall-cmd --reload #Refresh the firewall to take effect

firewall-cmd --zone=public--list-ports #View the firewall release port list

[ root@localhost ~]# firewall-cmd --zone=public--add-port=8080/tcp --permanent    #(--permanent takes effect permanently, after restarting without this parameter.effect)

[ root@localhost ~]# firewall-cmd --reload
