• CentOS 7开放端口和关闭防火墙


    开放端口

    永久的开放需要的端口

    sudo firewall-cmd --zone=public --add-port=3000/tcp --permanent
    sudo firewall-cmd --reload
    

    之后检查新的防火墙规则

    firewall-cmd --list-all
    

    关闭防火墙

    由于只是用于开发环境,所以打算把防火墙关闭掉

    //临时关闭防火墙,重启后会重新自动打开
    systemctl restart firewalld
    //检查防火墙状态
    firewall-cmd --state
    firewall-cmd --list-all
    //Disable firewall
    systemctl disable firewalld
    systemctl stop firewalld
    systemctl status firewalld
    //Enable firewall
    systemctl enable firewalld
    systemctl start firewalld
    systemctl status firewalld
