さくらVPSにCPANをインストールする方法
小粋空間 » レンタルサーバ » VPS » さくらVPSにCPANをインストールする方法
いまさらですが、さくらVPSにCPANをインストールする方法を紹介します。
PerlモジュールをCPANでアップデートしようと思ったのですが、CPANがインストールされていませんでした。
CPANはyumコマンドでインストールできます。サーバのアーキテクチャはx86_64なので、"perl-CPAN.x86_64"を指定します。
# yum install perl-CPAN.x86_64実行結果は次の通りです。
[root@wwwXXXXui ~]# yum install perl-CPAN.x86_64

Complete!インストール後、cpanの初期設定のため、"cpan"を実行します。
# cpan実行結果は下記です。出力は長いですが、12行目の「Would you like me to configure as much as possible automatically?」で"yes"を入力するだけです。
[root@wwwXXXXui ~]# cpan
CPAN is the world-wide archive of perl resources. It consists of about
300 sites that all replicate the same contents 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, lots of things have to be configured. Fortunately, most of
them can be determined automatically. If you prefer the automatic
configuration, answer 'yes' below.
If you prefer to enter a dialog instead, you can answer 'no' to this
question and I'll let you configure in small steps one thing after the
other. (Note: you can revisit this dialog anytime later by typing 'o
conf init' at the cpan prompt.)
Would you like me to configure as much as possible automatically? [yes] 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 or a personal directory.
