centos7 网络管理工具[0]

Posted on 2023年11月14日2025年5月6日 by

linux有通用的网络管理工具,就是不太集成,因此一般采用nmcli进行管理。

  • linux常用的命令:
nano /etc/hostname #配置主机名
cd /etc/sysconfig/network-scripts/
ll 
nano ifcfg-eth0 #查看网络信息ip,此文件名称具体会变,

ip addr

nano /etc/resolv.conf #查询dns配置

nano /etc/sysconfig/network #修改网关
  • ifconfig
yum install net-tools

  • NetworkManager+nmcli

安装NetworkManager

yum install NetworkManager
systemctl start NetworkManager #启动服务
nmcli device show #显示设备信息

查看设备状态

nmcli device status

systemctl restart network #设置网络生效
  • 内网设备探测
yum install nmap
nmap -sP 10.10.10.0/24
