Linux静态IP配置
linux获得ip地址有两种方式
1.动态获得dhcp动态分配ip地址 （动态主机配置协议 作用：给其他机器分配ip地址、子网掩码、网关、DNS服务器地址）应用层
2.静态配置（手工配置）
linux里如何静态配置ip地址
LANWANWLAN:wireless local area network
IPinternet protocol 互联网协议
nmcli:networkmanager client网络管理服务的客户端命令给用户使用的
查看ip地址
ipadd查看route配置
iprouteRocky Linux配置
修改配置文件/etc/NetworkManager/system-connections
