centos8用的是Nmcli（network的简写）

1.命令：systemctl status NetworkManager   之前的（network就不要用了）

systemctl status NetworkManager

不重启系统让网卡生效

改了ip重新激活
    先 nmcli connection reload  在执行下面的三个其中一个就可以   
       nmcli connection up ens33  
       nmcli device connect ens33
       nmcli device reapply ens33
    
    查看dns 
    cat /etc/resolv.conf

2.查看网络设备转态

nmcli device status

3.查看网络详细信息

nmcli device show ens33

4.设置静态ip地址 （这是直接设置，和你在配置文件里面改了的效果一样）

nmcli connection modify ens33 ipv4.addresses '192.168.1.100'

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3oxMzYxNTQ4MDczNw_size_16_color_FFFFFF_t_70 2][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3oxMzYxNTQ4MDczNw_size_16_color_FFFFFF_t_70 3][]

5.设置Dns

nmcli connection modify ens33 ipv4.dns '114.114.114.114'

6.设置网关

nmcli connection modify ens33 ipv4.gateway '192.168.1.1'

7.设置IP地址为dhcp自动获取

nmcli connection modify ens33 ipv4.method auto

其他参数也一样
