環境：
VM：VMware Player 5.0
OS：CentOS 6.5（2.6.32-431.el6.i686）
gcc-4.4.7-4
perl-5.10.1
安裝必要套件：gcc-c++、perl-CPANPLUS
# yum install -y gcc-c++ perl-CPANPLUS
CPANPLUS 是一個能夠幫你輕鬆安裝 CPAN 模組的工具，請依下列順序安裝。
CPANPLUS::Dist::Build //安裝完後要重啟 CPANPLUS 才會生效YAML
MLDBM
version
Test::Pod
Package::Generator
File::ReadBackwards
PAR::Dist
Archive::Tar
IO::Zlib
Data::OptList
Test::Fatal
Test::Requires
Module::Implementation
Package::Stash
Test::Spec
Test::Deep
Test::Trap
Data::Dump
ExtUtils::Constant
註 ：若模組安裝失敗可能與目前perl的版本有關，可至CPAN Testers Matrix查詢。
範例：除了CPANPLUS::Dist::Build安裝完後要重啟CPANPLUS以外，其餘模組可以用參數i一直安裝。
# cpanp
CPAN Terminal> i CPANPLUS::Dist::Build
Installing CPANPLUS::Dist::Build (0.76)
Module 'CPANPLUS::Dist::Build' requires 'ExtUtils::MakeMaker' to be installed
If you don't wish to see this question anymore
you can disable it by entering the following commands on the prompt:
's conf prereqs 1; s save'
1> Yes
2> No
3> Yes to all (for this module)
4> No to all (for this module)
Should I install this module? [1]: 3 //選3安裝所有相關的模組，如果不想每次都被問，可設定預設值，請參照設定1。
...安裝中
Module 'CPANPLUS::Dist::Build' installed successfully
No errors installing all modules
CPAN Terminal> q //離開CPANPLUS
#
# instmodsh //查詢已安裝模組
Available commands are:
l - List all installed modules
m - Select a module
q - Quit the program
cmd? l
Archive::Tar
CPAN::Perl::Releases

透過CPANPLUS安裝及初始化Perlbrew
CPAN Terminal> i App::perlbrew
...安裝中
Module 'App::perlbrew' installed successfully
No errors installing all modules
CPAN Terminal> q
Exiting CPANPLUS shell
# perlbrew init
perlbrew root (~/perl5/perlbrew) is initialized.
Append the following piece of code to the end of your ~/.bash_profile and start a
new shell, perlbrew should be up and fully functional from there:
source ~/perl5/perlbrew/etc/bashrc
Simply run `perlbrew` for usage details.
Happy brewing!
# source ~/perl5/perlbrew/etc/bashrc
使用下列指令可以查看現有哪些版本的 Perl 可以供安裝，所以還不能直接使用。
# perlbrew available
perl-5.19.9
perl-5.18.2
perl-5.16.3
perl-5.14.4
perl-5.12.5
perl-5.10.1
perl-5.8.9
perl-5.6.2
perl5.005_04
perl5.004_05
perl5.003_07
安裝 perl-5.14.4
# perlbrew install perl-5.14.4
Fetching perl 5.14.4 as /root/perl5/perlbrew/dists/perl-5.14.4.tar.bz2
Download http://www.cpan.org/src/5.0/perl-5.14.4.tar.bz2 to /root/perl5/perlbrew/dists/perl-5.14.4.tar.bz2
Installing /root/perl5/perlbrew/build/perl-5.14.4 into ~/perl5/perlbrew/perls/perl-5.14.4
This could take a while. You can run the following command on another shell to track the status:
tail -f ~/perl5/perlbrew/build.perl-5.14.4.log //觀察安裝過程
perl-5.14.4 is successfully installed.
# perlbrew list //查詢已安裝版本
perl-5.14.4
# perl -v
This is perl, v5.10.1 (*) built for i386-linux-thread-multi //系統預設版本
# perlbrew switch perl-5.14.4
# perl -v
This is perl 5, version 14, subversion 4 (v5.14.4) built for i686-linux //切換後目前系統版本
# perlbrew off //回到系統預設版本
注意！若直接從5.10.1升級至最新版本會失敗。設定1

I see you already have some hosts selected:
ftp://ftp.cpan.org/pub/CPAN/
http://www.cpan.org/
ftp://ftp.nl.uu.net/pub/CPAN/
ftp://cpan.valueclick.com/pub/CPAN/

If you'd like to stick with your current settings, just select 'Yes'.
Otherwise, select 'No' and you can reconfigure your hosts
Would you like to keep your current hosts? [Y/n]: n 是否保留原設定
Now we need to know where your favorite CPAN sites are located. Make a
list of a few sites (just in case the first on the array won't work).
If you are mirroring CPAN to your local workstation, specify a file:
URI by picking the CUSTOM option.
Otherwise, let us fetch the official CPAN mirror list and you can pick
the mirror that suits you best from a list by using the MIRROR option;
First, pick a nearby continent and country. Then, you will be presented
with a list of URLs of CPAN mirrors in the country you selected. Select
one or more of those URLs.
Note, the latter option requires a working net connection.
You can select VIEW to see your current selection and QUIT when you are done.
1> Mirror
2> Custom
3> View
4> Quit
Please choose an option [1]: 1
Now, we are going to fetch the mirror list for first-time configurations.
