最近在Esxi中配置ubuntu18.04 server记录如何配置静态IP。因为ubuntu18.04的网络管理程序使用netplan来管理，所有配置方式也更改了。

查看本机IP

ifconfig -a

查看当前配置文件

cat /etc/netplan/50-cloud-init.yaml

如果要使用静态IP的话，需要修改为下面的样子：

1
# This file is generated from information provided by
2
# the datasource.  Changes to it will not persist across an instance.
3
# To disable cloud-init's network configuration capabilities, write a file
4
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
5
# network: {config: disabled}
6
network:
7
    ethernets:
8
        enp0s3:
9
            addresses: [192.168.199.101/24, ]
10
            dhcp4: no
11
            dhcp6: no
12
            gateway4:  192.168.199.1
13
            nameservers:
14
                addresses: [8.8.8.8, 9.9.9.9]
15
    version: 2

将上述配置改成自己的IP、网关、DNS，最后运行生效配置。

netplan apply
