【Ubuntu server18.04 】使用netplan配置静态IP

1. 查看本机ip

$ ifconfig
docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 172.17.0.1  netmask 255.255.0.0  broadcast 172.17.255.255
        ether 02:42:97:70:eb:98  txqueuelen 0  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.193.131  netmask 255.255.255.0  broadcast 192.168.193.255
        inet6 fe80::20c:29ff:fe6e:f773  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:6e:f7:73  txqueuelen 1000  (Ethernet)
        RX packets 740  bytes 71366 (71.3 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 440  bytes 57899 (57.8 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 92  bytes 7100 (7.1 KB)

2. 查看本机网关

$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.193.2   0.0.0.0         UG    0      0        0 ens33
172.17.0.0      0.0.0.0         255.255.0.0     U     0      0        0 docker0

3. 编辑netplan默认配置文件

sudo vim /etc/netplan/00-installer-config.yaml

# This is the network config written by 'subiquity'
network:
  ethernets:
    ens33:
      dhcp4: no
      addresses: [192.168.193.131/24]
      gateway4: 192.168.193.2
      nameservers:
              addresses: [192.168.193.2]
  version: 2

4. 应用配置

$ sudo netplan apply

 

5. 检查连通性

ping 192.168.193.131
