在centos上安裝xe命令行的作用就不用多說了。首先在xenserver的安裝iso中找到xe命令的rpm包（在client_install這個目錄下），然后拷貝到centos上。如果直接用rpm命令安裝xe-cli-6.1.0-59235p.i686.rpm這個包，會提示依賴錯誤。這時改用yum命令來安裝，它會自動幫我們處理依賴。

這時我們改用yum來安裝，它會自動幫我們處理依賴問題
yum install xe-cli-6.1.0-59235p.i686.rpm
安裝好后，執行xe命令如果報錯
Unhandled exception
File "stunnel.ml", line 137,characters 20-25: Pattern matching failed
這時需要安裝stunnel包，使用如下命令安裝
yum install stunnel
都安裝好后，可以正常執行xe命令，基本用法如下
xe -s ip -u username -pw password command param
-s選項指明xenserver服務器的IP地址
-u選項指明XenServer服務器的用戶名
-pw選項指明用戶密碼
command是xe子命令，如host-list等
param是命令的參數，如uuid=xxxxx等
