本人低配五台机器,用来学习Proxmox,首先把这几台电脑集群起来,在每台机器上同步时间:
用这条命令:
#vi /etc/systemd/timesyncd.conf
打开timesyncd.conf文件,在文件里加入这条语句

 [Time] 
 Servers=ntp1.aliyun.com ntp2.aliyun.com time.apple.com

 在每个主机都同步时间。

 添加开源软件,先把原来的文件删掉:
 rm -f /etc/apt/sources.list.d/pve-enterprise.list

 添加新的文件:
 echo "deb http://download.proxmox.com/debian/pve stretch pve-no-subscription" >/etc/apt/sources.list.d/pve-install-repo.list
 ![](http://i2.51cto.com/images/blog/201811/02/d7f8fc1ea50ea3a7c2f87b8cb537ef17.jpg?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)

 下载密钥:
 wget http://download.proxmox.com/debian/proxmox-ve-release-5.x.gpg -o /etc/apt/trusted.gpg.d/proxmox-ve-release-5.x.gpg

 下载更新:
   apt update && apt dist-upgrade
     ![](http://i2.51cto.com/images/blog/201811/02/0218eef27ef06641faf68a90fa32421f.jpg?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)
     每个主机都要执行上面几条命令。

     安装Ceph
     pveceph install
     ![](http://i2.51cto.com/images/blog/201811/02/9e7e3aaaaf1a07840c02dc6884324e5a.jpg?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)

 每个主机都安装上面这条命令。

 在其中一台主机运行这条命令
 pveceph init --network 192.168.30.0/24
 ![](http://i2.51cto.com/images/blog/201811/02/9f035f04972d5a4edaf2e223c7efdf2f.jpg?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)

 在每个节点都运行下面的两条命令:
 pveceph createmon
 pveceph createmgr

 剩下的都可以Web界面中完成了。
