1.准备部署环境
master 192.168.40.162
node 192.168.40.220
2.下载部署包(从192.168.40.33复制部署包)
scp /opt/kylincloud2_2.0_ft2000_v0.0.1.13_20200511.tar.gz [email protected]:/opt/
3.免密认证
通过192.168.40.192对192.168.40.162及192.168.40.220做免密认证，即master节点对自身及所有node节点做免密认证
(1)ssh-keygen -t rsa
(2)cat id_rsa.pub>>authorized_keys
(3)chmod 710 authorized_keys
(4)scp -r authorized_keys [email protected]:~/.ssh
4.时间同步
(1)ntpdate 192.168.40.253（此命令分别执行在master及node）
将192.168.40.162和192.168.40.220统一与192.168.40.253时间保持一致，即master及所有节点保持统一一致时间
(2)hwclock -w（此命令分别执行在master及node）
将软件时间写入硬件时间，硬件时间是BIOS的时间
5.根据需求修改default.yaml文件

部署模式为单控,以及多控不需要lvs的时候注释

state: MASTER

ip: 192.168.40.208

master:

ip: 192.168.40.33 #第一个ip必须是执行脚本所在的机器

ip: 192.168.40.161
- name: master3
ip: 192.168.40.162
nodes:
- name: node-1

新加计算节点,初次部署注释即可
addnodes:
- name: node-3

label: rack=bgpt
- name: node-4
ip: 192.168.40.208
