Iptables-I RH-Firewall-1-INPUT-m state-state NEW-m tcp-p tcp-dport 21-j ACCEPT
Iptables-I RH-Firewall-1-INPUT-m state-state NEW-m tcp-p tcp-dport 80-j ACCEPT

Service iptables stop
C. Reset and load the Firewall

Enable port 80 of the firewall on CentOS

 

 

Note: Sometimes the installation may be inaccessible and port 80 must be enabled.

The main reason is the Firewall:
Run the/etc/init. d/iptables status Command to check whether port 80 is enabled. If port 80 is not enabled, you can use either of the following methods:
1. Modify the vi/etc/sysconfig/iptables command to add the firewall to open port 80
-A RH-Firewall-1-INPUT-m state -- state NEW-m tcp-p tcp -- dport 80-j ACCEPT
2. Disable the Firewall
/Etc/init. d/iptables stop
# Start
# Restart
Permanently disable the firewall chkconfig -- level 35 iptables off
