【CentOS5.6】CPAN（The Comprehensive Perl Archive Network）を利用する際のセットアップ

CentOS5.6で、CPAN（The Comprehensive Perl Archive Network）を利用する際のセットアップ

（１）必要なモノをepelリポジトリからyumでインストールする

　epelリポジトリ利用のための設定は、次のパッケージをインストールするだけで自動的になされる。

# rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm

# yum install ncftp

　ncftpは高機能のファイル転送プログラムらしい。

次に行うCPAN利用のためのセットアップではこのプログラムがなければ進めない。

（２）CPAN利用のためのセットアップを行う

初回のみいろいろ質問される。セットアップ後は同じコマンドでCPANのプロンプトがすぐに現れる。

セットアップでは最後の方で質問される国の選択とリポジトリの選択以外はエンターキーでデフォルトを選択すればよい。

# perl -MCPAN -e shell

/usr/lib/perl5/5.8.8/CPAN/Config.pm initialized.

CPAN is the world-wide archive of perl resources. It consists of about

100 sites that all replicate the same contents all around the globe.

Many countries have at least one CPAN site already. The resources

found on CPAN are easily accessible with the CPAN.pm module. If you

want to use CPAN.pm, you have to configure it properly.

If you do not want to enter a dialog now, you can answer 'no' to this

question and I'll try to autoconfigure. (Note: you can revisit this

dialog anytime later by typing 'o conf init' at the cpan prompt.)

Are you ready for manual configuration? [yes]

The following questions are intended to help you with the

configuration. The CPAN module needs a directory of its own to cache

important index files and maybe keep a temporary mirror of CPAN files.

This may be a site-wide directory or a personal directory.

First of all, I'd like to create this directory. Where?

CPAN build and cache directory? [/root/.cpan]

If you want, I can keep the source files after a build in the cpan

home directory. If you choose so then future builds will take the

files from there. If you don't want to keep them, answer 0 to the

next question.

How big should the disk cache be for keeping the build directories

with all the intermediate files?

Cache size for build directory (in MB)? [10]

By default, each time the CPAN module is started, cache scanning

is performed to keep the cache size in sync. To prevent from this,

disable the cache scanning with 'never'.

Perform cache scanning (atstart or never)? [atstart]

To considerably speed up the initial CPAN shell startup, it is

possible to use Storable to create a cache of metadata. If Storable

is not available, the normal index mechanism will be used.

Cache metadata (yes/no)? [yes]

The next option deals with the charset your terminal supports. In

general CPAN is English speaking territory, thus the charset does not

matter much, but some of the aliens out there who upload their

software to CPAN bear names that are outside the ASCII range. If your

terminal supports UTF-8, you say no to the next question, if it

supports ISO-8859-1 (also known as LATIN1) then you say yes, and if it

supports neither nor, your answer does not matter, you will not be

able to read the names of some authors anyway. If you answer no, names

will be output in UTF-8.

Your terminal expects ISO-8859-1 (yes/no)? [yes]

If you have one of the readline packages (Term::ReadLine::Perl,

Term::ReadLine::Gnu, possibly others) installed, the interactive CPAN

shell will have history support. The next two questions deal with the

filename of the history file and with its size. If you do not want to

set this variable, please hit SPACE RETURN to the following question.

File to save your history? [/root/.cpan/histfile]

Number of lines to save? [100]

The CPAN module can detect when a module that which you are trying to

build depends on prerequisites. If this happens, it can build the

prerequisites for you automatically ('follow'), ask you for

confirmation ('ask'), or just ignore them ('ignore'). Please set your

policy to one of the three values.

Policy on building prerequisites (follow, ask or ignore)? [ask]

The CPAN module will need a few external programs to work properly.

Please correct me, if I guess the wrong path for a program. Don't

panic if you do not have some of them, just press ENTER for those. To

disable the use of a download program, you can type a space followed

by ENTER.

Where is your gzip program? [/bin/gzip]

Where is your tar program? [/bin/tar]

Where is your unzip program? [/usr/bin/unzip]

Where is your make program? [/usr/bin/make]

Where is your links program? [/usr/bin/links]

Where is your wget program? [/usr/bin/wget]

Warning: ncftpget not found in PATH

Where is your ncftpget program? []

Warning: ncftp not found in PATH

Where is your ncftp program? []

Where is your ftp program? [/usr/kerberos/bin/ftp]

Where is your gpg program? [/usr/bin/gpg]

What is your favorite pager program? [/usr/bin/less]

What is your favorite shell? [/bin/bash]

Every Makefile.PL is run by perl in a separate process. Likewise we

run 'make' and 'make install' in processes. If you have any

parameters (e.g. PREFIX, LIB, UNINST or the like) you want to pass

to the calls, please specify them here.

If you don't understand this question, just press ENTER.

Parameters for the 'perl Makefile.PL' command?

Typical frequently used settings:

PREFIX=~/perl non-root users (please see manual for more hints)

Your choice: []

Parameters for the 'make' command?

Typical frequently used setting:

-j3 dual processor system

Your choice: []

Parameters for the 'make install' command?

Typical frequently used setting:

UNINST=1 to always uninstall potentially conflicting files

Your choice: []

Sometimes you may wish to leave the processes run by CPAN alone

without caring about them. As sometimes the Makefile.PL contains

question you're expected to answer, you can set a timer that will

kill a 'perl Makefile.PL' process after the specified time in seconds.

If you set this value to 0, these processes will wait forever. This is

the default and recommended setting.

Timeout for inactivity during Makefile.PL? [0]

If you're accessing the net via proxies, you can specify them in the

CPAN configuration or via environment variables. The variable in

the $CPAN::Config takes precedence.

Your ftp_proxy?

Your http_proxy?

Your no_proxy?

You have no /root/.cpan/sources/MIRRORED.BY

I'm trying to fetch one

LWP not available

CPAN: Net::FTP loaded ok

Fetching with Net::FTP:

ftp://ftp.perl.org/pub/CPAN/MIRRORED.BY

Now we need to know where your favorite CPAN sites are located. Push

a few sites onto the array (just in case the first on the array won't

work). If you are mirroring CPAN to your local workstation, specify a

file: URL.

First, pick a nearby continent and country (you can pick several of

each, separated by spaces, or none if you just want to keep your

existing selections). Then, you will be presented with a list of URLs

of CPAN mirrors in the countries you selected, along with previously

selected URLs. Select some of those URLs, or just keep the old list.

Finally, you will be prompted for any extra URLs -- file:, ftp:, or

http: -- that host a CPAN mirror.

(1) Africa

(2) Asia

(3) Central America

(4) Europe

(5) North America

(6) Oceania
