nmcli connection add等效nmcli c a
sudo nmcli c a con-name 'ens33ConnTest001' ifname 'ens33' type ethernet ipv4.method 'manual' ipv4.addresses "192.168.168.224/24 , 192.168.168.225/24,192.168.168.226/24" +ipv4.address '192.168.168.227/24' +ipv4.a '192.168.168.228/24' +ipv4.addre '192.168.168.229/24 , 192.168.168.230/24 , 192.168.168.231/24' +ipv4.addr "192.168.168.232/24" +ipv4.ad '192.168.168.233/24' +ipv4.a 192.168.168.234/24,192.168.168.235/24 ipv4.gate 192.168.168.2 ipv4.dns 192.168.168.2,119.29.29.29,180.76.76.76,223.6.6.6,8.8.4.4,114.114.115.115 +ipv4.dns '223.5.5.5 , 8.8.8.8 , 1.1.1.1 , 114.114.114.114' +ipv4.dns 101.226.4.6,123.125.81.6 ipv4.ignore-auto-dns true ipv4.dns-search qq.com
ipv4.a(ipv4.addresses)可以设置多个(,逗号分隔,可以有空格),但只能出现一次, +ipv4.a(+ipv4.addresses)可以设置多个(,逗号分隔)可以出现多次
网关ipv4.g(ipv4.gateway)只能有一个, (在图形界面也只能设置一个)
ipv4.dns不能简写,可一次设置多个, +ipv4.dns可多次设置多个
ipv4.dns-search可简写为ipv4.dns-s , 搜索域
ipv4.ignore-auto-dns 取值 true|fasle 是否跳过自动域名 , 最简只能写成ipv4.ignore-auto-d
上面的nmcli控制台语句会在/etc/NetworkManager/system-connections/ 目录生成 con-name指定的名称加上 .nmconnection 后缀的配置文件, 如果同名文件已存在, 就会再加一个UID
上面的nmcli控制台语句生成的对应的配置文件的内容为
[connection]

netplan可以从配置文件创建连接, NetworkManager暂时不知可否从配置文件创建连接,只能从图形界面或nmtui或nmcli c a创建新连接, nmcli c load只能加载已创建连接的配置文件, 不能加载自己添加的配置文件
添加一个简洁的,可当基础模板
sudo nmcli connection add con-name 'Concise' ifname 'ens33' type 'ethernet' ipv4.method 'manual' ipv4.addresses "192.168.168.224/24" ipv4.gateway '192.168.168.2' ipv4.dns '192.168.168.2' ipv4.ignore-auto-dns false ipv4.dns-search google.cn
con-name, ifname , type 没法简写 , 区分大小写
可以添加几个连接可用于做试验,或者方便快速切换
sudo nmcli c a con-name 'con-name' ifname 'ens33' type 'EtherneT' ipv4.me 'manual' ipv4.a 192.168.168.224/24 ipv4.g 192.168.168.2
EtHeRnEt 不区分大小写 , 到配置文件会变为小写 ethernet
sudo nmcli c a con-name 'ens33自动获取IP' ifname 'ens33' type EtHeRnEt ipv4.me auto
ipv4.xxx 也不区分大小写, 到配置文件都变小写
sudo nmcli c a con-name '阿里dns' ifname ens33 type ethernet IpV4.me ManuaL iPV4.A 192.168.168.224/24 IPv4.g 192.168.168.2 ipv4.ignore-auto-dns true ipv4.dns 223.6.6.6,223.5.5.5

con-name, ifname , type 没法简写 , 而且区分大小写
sudo nmcli c a con-name '谷歌dns' ifname ens33 type ETHERnet iPV4.mE mANuAl IpV4.aDDr 192.168.168.224/24 ipV4.GAte 192.168.168.2 IpV4.IgNorE-AUto-DnS TruE ipV4.dNS 8.8.4.4,8.8.8.8 ipV4.DnS-sEaRcH google.cn

修改自动DNS
sudo nmcli c m 'ens33ConnTest001' ipv4.ignore-auto-dns false
resolvectl 命令可以查看 dns
