It is necessary to configure the Iptables firewall under CentOS. Let's learn how to configure! Set up firewalls in Linux, take CentOS as an example, and open the Iptables configuration file: Default Vi/etc/sysconfig/iptablesQuery for open 80 ports through the/etc/init.d/iptables status command if there are no two ways to handle: 1. Modify the Vi/etc/sysconfig/iptables command to add the firewall to open
