Firewall shutdown issues in CentOS 7

The newly installed CentOS 7 found that some of the program ports were off, thinking of firewalls and SELinux

Selinx Good close/etc/sysconfig/selinux append selinux=disabled

Firewall thought is also very good to get, according to the old ritual, service iptables stop or chkconfig--level iptables off

Run Systemctl list-unit-files after reboot | grep IP found another ip6tables chkconfig--level ip6tables off

Re-run Systemctl list-unit-files | grep IP Discovery All disables still not through

No way, only add rules, Tptables-i INPUT 1-p tcp--dport 6259-j ACCEPT

Then the service iptables the save port through

I think this is not a bug, maybe I did not find the method, please tell

The firewall in Centos7 is tuned to Firewalld, try Systemctl stop firewalld to turn off the firewall.
I installed CentOS 7 with minimal configuration (OS + dev tools). I am trying to open the port for httpd service, but the something wrong with my iptables service ... what ' s wrong w ITH it? What am I doing wrong?

With RHEL 7/centos 7, FIREWALLD is introduced to manage iptables. IMHO, FIREWALLD is more suited for workstations than for server environments.

It's possible to go, and a more classic iptables setup. First, stop and mask the FIREWALLD service:

systemctl stop firewalldsystemctl mask firewalld

Then, install the Iptables-services package:

yum install iptables-services

Enable the service at Boot-time:

systemctl enable iptables

Managing the Service

systemctl [stop|start|restart] iptables

Saving your firewall rules can be done as follows:

service iptables save

Or

/usr/libexec/iptables/iptables.init save
