node2:/root#cpanm XML::Simple
--> Working on XML::Simple

yum install rex

cpanm Rex

安装rex 

root@StorageServer1 ~]# cpanm Rex
--> Working on Rex

==> Found dependencies: ExtUtils::MakeMaker
安装过程中它自己会解决模块相关的依赖关系，可能会有一些底层的库需要手动去安装，比如我在安装过程中就失败了

! Installing the dependencies failed: Module 'XML::LibXML' is not installed, Module 'XML::Simple' is not installed

! Bailing out the installation for Rex-1.3.3.

提示有个XML::LibXML相关的模块安装不成功，这个和它依赖的相关的底层xml库有关系，所以我将libxml相关的底层库都安装一下就行了。

[root@StorageServer1 ~]# yum install libxml*
然后再安装rex
