Ubuntu系统如何配置静态IP地址

• 查看网卡和IP地址

  qv123@localhost:~$ ip addr
  1: lo:  mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
      link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
      inet 127.0.0.1/8 scope host lo
         valid_lft forever preferred_lft forever
      inet6 ::1/128 scope host 
         valid_lft forever preferred_lft forever
  2: ens33:  mtu 1500 qdisc fq_codel state UP group default qlen 1000
      link/ether 00:0c:29:ca:b3:ef brd ff:ff:ff:ff:ff:ff
      altname enp2s1
      inet 192.168.10.164/24 metric 100 brd 192.168.10.255 scope global dynamic ens33
         valid_lft 1732sec preferred_lft 1732sec
      inet6 fe80::20c:29ff:feca:b3ef/64 scope link 
         valid_lft forever preferred_lft forever

• 修改配置文件：(root用户才可以使用哦eof)

  cat << eof > /etc/netplan/00-installer-config.yaml
  # This is the network config written by 'subiquity'
  network:
    ethernets:
      ens33:
        addresses: [192.168.10.201/24]
        routes:
          - to: default
            via: 192.168.10.2
        dhcp4: false
        nameservers:
            addresses: [8.8.8.8, 144.144.144.144]
    version: 2
    renderer: networkd
  eof

• 生效：

  sudo netplan apply
