使用Proxmox 5.4进行集群配置，支持冷迁移。没有配置共享存储，不支持热迁移。

1 环境准备

1.1网络

pve2 192.168.189.2 集群主

pve3 192.168.189.3

pve4 192.168.189.4

openwrt 192.168.189.254

1.2主机名

/etc/hosts

192.168.189.2 pve2 pve2.ict.com

192.168.189.3 pve3 pve3.ict.com

192.168.189.4 pve4 pve4.ict.com

1.3硬盘

除开安装系统的盘，另外有一个500G的SCSI硬盘，路径为 /dev/sdb

1.4重新生成密钥对

root@pve2:~# ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): /root/.ssh/id_rsa already exists. Overwrite (y/n)? y Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub.

cat .ssh/id_rsa.pub > .ssh/authorized_keys

1.5改源

没有付费，那就去掉企业版的源，用免费的。

sed -i 's/deb/#deb/g' /etc/apt/sources.list.d/pve-enterprise.list

echo "deb http://download.proxmox.com/debian/pve stretch pve-no-subscription" >/etc/apt/sources.list.d/pve-install-repo.list

wget http://download.proxmox.com/debian/proxmox-ve-release-5.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-5.x.gpg

apt update && apt dist-upgrade

1.6安装常用工具

安装net-tools , ntpdate, vim，openvswitch-switch

apt install ntpdate net-tools vim

apt install openvswitch-switch

1.7同步时间

ntpdate-debian

1.8注意

三台主机都要操作第4~7步骤。

2 建立集群

2.1创建集群

通过网页操作， 在pve2上建立集群。

2.2加入集群

通过网页操作，加入时需复制主控机的信息到本机。
