CentOS Open Firewall 80 port
Note: Sometimes the installation may not be accessible, you need to open port 80
A big reason is the firewall:
Query 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 80 ports

The code is as follows	Copy Code
#/sbin/iptables-i input-p tcp–dport 80-j ACCEPT #/sbin/iptables-save

2. Close the firewall

The code is as follows	Copy Code
#/etc/init.d/iptables Stop/start/restart stop/start/reboot #restart reboot

Permanently shutdown firewall Chkconfig–level iptables off
