static IP

多节点统一化管理

ip a # 查看网络环境，主要查看网卡名称，

sudo gedit /etc/netplan/01-network-manager-all.yaml 

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager
  ethernets:
     ens33: #配置的网卡名称,使用ifconfig -a查看得到
       dhcp4: no #dhcp4关闭
       addresses: [192.168.1.200/24] #设置本机IP及掩码
       gateway4: 192.168.1.1 #设置网关
       nameservers:
         addresses: [8.8.8.8,223.5.5.5] #设置DNS

sudo netplan apply

修改hosts名称

#master节点:
hostnamectl set-hostname master
#workernode1节点：
hostnamectl set-hostname worker

sudo gedit /etc/hosts
192.168.1.200 master
192.168.1.201 worker
