firewall-cmd --zone=public --add-port=28017/tcp --permanent
    命令含义：

    –zone #作用域

    –add-port=80/tcp #添加端口，格式为：端口/通讯协议

    –permanent #永久生效，没有此参数重启后失效

    重启防火墙
    firewall-cmd --reload #重启firewall
    systemctl stop firewalld.service #停止firewall
    systemctl disable firewalld.service #禁止firewall开机启动
    firewall-cmd --state #查看默认防火墙状态（关闭后显示notrunning，开启后显示running）
    
    查看已经开放的端口：
    firewall-cmd --list-ports

Enable MongoDB‘s free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).

The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
