liunx基础命令


一 防火墙

  问题:老是关闭防火墙太麻烦,所以选择彻底关闭防火墙,发现每次都记不住命令!

  下面是red hat/CentOs7关闭防火墙的命令!

  1:查看防火状态

    systemctl status firewalld

    service  iptables status

  2:暂时关闭防火墙

    systemctl stop firewalld

    service  iptables stop

  3:永久关闭防火墙

    systemctl disable firewalld

    chkconfig iptables off

  4:重启防火墙

    systemctl enable firewalld

    service iptables restart  

  5:永久关闭后重启

    chkconfig iptables on
