  • How can i use iptables on centos 7?

    I installed CentOS 7 with minimal configuration (os + dev tools). I am trying to open 80 port for httpdservice, but something wrong with my iptables service ... what's wrong with it? What am I doing wrong?


    # ifconfig/sbin/service iptables save
    bash: ifconfig/sbin/service: No such file or directory
    
    
    # /sbin/service iptables save
    The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl.
    
    # sudo service iptables status
    Redirecting to /bin/systemctl status  iptables.service
    iptables.service
       Loaded: not-found (Reason: No such file or directory)
       Active: inactive (dead)
    
    # /sbin/service iptables save
    The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl.
    
    # sudo service iptables start
    Redirecting to /bin/systemctl start  iptables.service
    Failed to issue method call: Unit iptables.service failed to load: No such file or directory.  




    With RHEL 7 / CentOS 7, firewalld was introduced to manage iptables. IMHO, firewalld is more suited for workstations than for server environments.

    It is possible to go back to a more classic iptables setup. First, stop and mask the firewalld service:

    systemctl stop firewalld
    systemctl mask firewalld
      

    Then, install the iptables-services package:

    yum install iptables-services
      

    Enable the service at boot-time: IT网,http://www.it.net.cn

    systemctl enable iptables
      

    Managing the service

    systemctl [stop|start|restart] iptables
      

    Systemctl doesn't seem to manage the save action like you were able to do in the past with service:

    /usr/libexec/iptables/iptables.init save  

    This fixed it: Linux学习,http:// linux.it.net.cn

    yum install iptables-services
    systemctl mask firewalld
    systemctl enable iptables
    systemctl enable ip6tables
    systemctl stop firewalld
    systemctl start iptables
    systemctl start ip6tables
