修改网卡名称
查看原网卡名称为ens33
[[email protected] ~]#ifconfig

修改网卡名称为eth0,修改内核参数
[[email protected] ~]#vim /etc/default/grub
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=2
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
#在引号之间增加如下几行
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
生成grub配置文件
[[email protected] ~]#grub-mkconfig -o /boot/grub/grub.cfg

重启系统再次查看网卡名称
[[email protected] ~]#ifconfig

修改IP地址为静态IP地址
编辑配置文件
[[email protected] ~]#vim /etc/netplan/01-netcfg.yaml
network:
version: 2
renderer: networkd
ethernets:
#网卡名称
eth0:
addresses: [192.168.8.234/24]
gateway4: 192.168.8.2
nameservers:
addresses: [8.8.8.8]
使配置文件生效
[[email protected] ~]#netplan apply
[[email protected] ~]#ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.8.234 netmask 255.255.255.0 broadcast 192.168.8.255

永久修改DNS地址
[[email protected] ~]#vim /etc/systemd/resolved.conf
#取消注释,并且加入DNSIP地址
[Resolve]
DNS=8.8.8.8
#FallbackDNS=
#Domains=
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
#Cache=yes
#DNSStubListener=yes
