环境准备

为了演示简单，准备两台4GB内存,20GB硬盘的虚拟机，操作系统为ubuntu18.04-server

角色	IP	HostName
Master	192.168.47.144	master-k8s
Node	192.168.47.145	node1-k8s

前置准备

前置准备部分在master和node1都要分别执行：

换源

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

sudo vim /etc/apt/sources.list

# 阿里源
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

sudo apt update && sudo apt upgrade

配置静态IP

设置root用户密码，并使用root用户登录

sudo passwd root
su root

分别配置master和node1的静态ip：

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

# master-k8s
network:
    ethernets:
        ens33:
            addresses: [192.168.47.144/24]
            dhcp4: false
            gateway4: 192.168.47.2
            nameservers:
                addresses: [192.168.47.2]
            optional: true
    version: 2

# node1-k8s
network:
    ethernets:
        ens33:
            addresses: [192.168.47.145/24]
            dhcp4: false
            gateway4: 192.168.47.2
            nameservers:
                addresses: [192.168.47.2]
            optional:
