i have a 1and1 hosting account and would like to install some Perl CPAN modules that are not part of the standard host package. Is it possible to install modules without ROOT access? If so, how do i do that? Thanks for the pointers in advance.
cpanminus is quickly becoming the choice interface for CPAN. It supports installing packages in to the user's home directory.
Its usage is frightening simple. To install the cpanminus package locally:
curl -L http://cpanmin.us | perl - App::cpanminus
To install an arbitrary package:
curl -L http://cpanmin.us | perl - Lingua::Romana::Perligata
Remember to add the user's local library to the PERL5LIB environment variable.
export PERL5LIB=$HOME/perl5/lib/perl5:$PERL5LIB
I would suggest you use perlbrew and install a whole build of Perl in your account, not just modules. Less headaches that way, especially when the provider decides to update the system Perl.
This is an excellent article about installing perl modules as a regular (non-root) user:
For installing modules to a local directory, you can use local::lib.
