1.準備部署環境
master 192.168.40.162
node 192.168.40.220
2.下載部署包(從192.168.40.33復制部署包)
scp /opt/kylincloud2_2.0_ft2000_v0.0.1.13_20200511.tar.gz [email protected]:/opt/
3.免密認證
通過192.168.40.192對192.168.40.162及192.168.40.220做免密認證，即master節點對自身及所有node節點做免密認證
(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.時間同步
(1)ntpdate 192.168.40.253（此命令分別執行在master及node）
將192.168.40.162和192.168.40.220統一與192.168.40.253時間保持一致，即master及所有節點保持統一一致時間
(2)hwclock -w（此命令分別執行在master及node）
將軟體時間寫入硬體時間，硬體時間是BIOS的時間
5.根據需求修改default.yaml檔案

vip: 192.168.40.33 #單控模式為 master的ip,多控模式下為虛擬ip，跟集群同網段且不被占用
oldvip： 192.168.17.222 #默認注釋掉，當使用 --ip引數時需要將歷史的vip地址寫入

DNS_ip: 10.10.1.10

部署模式為單控,以及多控不需要lvs的時候注釋
lvs:
- name: lvs-1
ip: 192.168.40.207
state: MASTER
- name: lvs-2
ip: 192.168.40.208
state: BACKUP
master:
- name: master1
ip: 192.168.40.33 #第一個ip必須是執行腳本所在的機器
- name: master2
ip: 192.168.40.161
- name: master3
ip: 192.168.40.162
nodes:
- name: node-1
ip: 192.168.40.34
label: rack=bgpt
- name: node-2
ip: 192.168.40.223
label: rack=bgpt1
- name: node-3
ip: 192.168.40.35
label: rack=bgpt1
- name: node-4
ip: 192.168.40.224

ip: 192.168.40.207
label: rack=bgpt
- name: node-6
ip: 192.168.40.208

新加計算節點,初次部署注釋即可
addnodes:
- name: node-3
ip: 192.168.40.35
label: rack=bgpt
- name: node-4
ip: 192.168.40.208
