Proxmox VE2.2虚拟化安装配置学习笔记（二）
就是这样，你已经创建了一个集群。你可以检查下正在运行的主机：
server2:
pveca -l
应该在输出结果中显示两个主机的信息:
server2:~# pveca -l
CID―-IPADDRESS―-ROLE-STATE――�CUPTIME―LOAD―-MEM―ROOT―DATA
1 : 172.16.1.200 M S 00:15 0.00 5% 1% 0%
2 : 172.16.1.201 N S 00:04 0.08 15% 1% 0%
server2:~#
二：现在在2.2这个版本下创建群集命令如下：
在Server1上运行以下命令：
Server1：
1:创建群集名称
root@server1:~# pvecm create korolev

2：查看集群状态：
root@server1:~# pvecm status

在server2上运行以下命令：
Server2：
添加群集节点：
root@server2:~# pvecm add 172.16.1.200 //输入集群master的IP地址

特别是这个错误最常出现，网上有建议重启一下再试着添加，我这里亲测发现虽然这里提示这个错误失败，将集群master和这台主机slave都重启一下之后，再登录到要添加到集群master的slave主机上尝试添加：
root@server2:~# pvecm add 172.16.1.200
authentication key already exists //提示已经存在了，说明先前已添加成功了！
root@server2:~# pvecm status //查看集群状态，发现nodes变成2个了

***总结一下***出现以上错误的原因我觉的应该是由于在master主机server1上创建了集群之后需要重启之后生效，不然在其他slave主机上运行运行添加到集群就会经常出现添加失败fail或者再次尝试添加时候提示” pve configuration filesystem not mounted”错误。
再回到集群master主机server1上：
Server1：
root@server1:~# pvecm nodes //查看节点信息
Node Sts Inc Joined Name
1 M 12 2012-12-11 21:17:51 server1

现在我们回到Proxmox的控制面http://172.16.1.200/(server2.proxmox.com不需要控制面板！因为现在是一个群集所以即使用server2IP登录，界面显示一样，最好用master主机IP来管理集群。)并查看群集，在这里将会显示两台服务器：
![clip_image001[8]](http://img1.51cto.com/attachment/201212/19/2118260_13559310851R6k.jpg "clip_image001[8]")
4 添加设备模板
在我们创建OpenVZ容器之前，我们至少要在我们的系统当中添加一个操作系统模板（对于KVM客户机来说，你不单可以添加ISO文件，也可以直接从OS CD或者DVD来安装）。Proxmox2.2相对于之前的老版本在添加模板的时候发生了很多变化，接下来一一详细做一下添加模板步骤：
![clip_image002[12]](http://img1.51cto.com/attachment/201212/19/2118260_1355931085hZEx.jpg "clip_image002[12]")
点击节点主机，选择本地存储―内容―模板。你将会发现列出的众多openve的模板，这里可以下载下来使用：
![clip_image003[8]](http://img1.51cto.com/attachment/201212/19/2118260_13559310853R1x.jpg "clip_image003[8]")
在这里，你将会看到一个Proxmox项目提供的templates列表，分admin/mail/system/www等几类，你可以直接下载这些系统到本地存储然后使用。
![clip_image004[10]](http://img1.51cto.com/attachment/201212/19/2118260_1355931085KyWX.jpg "clip_image004[10]")
可能下载不成功，由于自己的接点主机只在局域网中做测试，没有连到internet所以没法下载成功，其实可以采用下边的方法解决：
理论上讲-这些系统的链接太老了，已经不再适合我们了，你可以去http://download.proxmox.com/appliances/然后去访问admin, mail, system, 或者www 文件夹下载你需要的templates到你的本地硬盘里。
![clip_image005[8]](http://img1.51cto.com/attachment/201212/19/2118260_1355931085Jya5.jpg "clip_image005[8]")
![clip_image006[12]](http://img1.51cto.com/attachment/201212/19/2118260_1355931085cjXu.jpg "clip_image006[12]")
将这些模板下载下来，然后在Local选项里，你可以把templates上传到Proxmox master主机上（这里是限于测试条件，只能将模板放在本地存储上，其实如果实体设备上有现成的高性能存储，还是建议放在实体存储的LUN中，这样各个节点读取起来方便。）：
