Proxmox5.2集羣安裝Ceph

本人低配五臺機器，用來學習Proxmox，首先把這幾臺電腦集羣起來，在每臺機器上同步時間：
用這條命令：
#vi /etc/systemd/timesyncd.conf
打開timesyncd.conf文件，在文件里加入這條語句

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

 在每個主機都同步時間。

 添加開源軟件，先把原來的文件刪掉：
 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=)

 下載密鑰：
 wget http://download.proxmox.com/debian/proxmox-ve-release-5.x.gpg -o /etc/apt/trusted.gpg.d/proxmox-ve-release-5.x.gpg

 下載更新：
   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=)
     每個主機都要執行上面幾條命令。

     安裝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=)

 每個主機都安裝上面這條命令。

 在其中一臺主機運行這條命令
 pveceph init --network 192.168.30.0/24

 在每個節點都運行下面的兩條命令：
 pveceph createmon
 pveceph createmgr

 剩下的都可以Web界面中完成了。
