Restart your computer. The  1.centos operating system firewall has already opened the 80 and 22 port  2 by default. This should also be done without restarting the computer: #/etc/init.d/iptables Restart the firewall off, shutting down its services:  3. View firewall information: #/etc/init.d/iptables status 4. Shutdown Firewall Service: #/etc/init.d/iptables stop  three. Permanently shut down the firewall   we can also permanently shut down the firewall , but I do not recommend it. Permanently shut down the firewall can do this: #chkconfig –level iptables off can also be directly modified/etc/sysconfig/iptables add a-a rh-firewall-1-input- M state--state new-m tcp-p TCP--dport 80-j ACCEPT
