查看perl模块和cpan模块介绍
1. Check whether you have 'perl-CPAN‘ package installed in your system.For checking ‘perl-CPAN’ package run following in your shell.
# rpm -q perl-CPAN
If perl-CPAN package is installed, you will get the output like this
perl-CPAN-1.9402-116.fc13.i686
else, you will get output like this
package perl-CPAN is not installed
and that the case you need to install it. You can install it via using yum, yum install perl-CPAN or from rpm, from “rpm.pbone.net” you can obtain “perl-CPAN rpm’s”.
2. Running the command "perl -MCPAN -e shell" will brought you to a CPAN command prompt
# perl -MCPAN -e shell
Terminal does not support AddHistory.
cpan shell -- CPAN exploration and modules installation (v1.9402)
Enter 'h' for help.
cpan>
Note : If this is the first time you’ve run CPAN, it’s going to ask you a series of questions – in most cases the default answer is fine.
If you got an error given below, then you need to confirm the "perl-CPAN" package’s existence in the sytem
Can't locate CPAN.pm in @INC (@INC contains: /usr/local/lib/perl5 /usr/local/share/perl5 /usr/local/share/perl5 /usr/lib/perl5 /usr/share/perl5 /usr/share/perl5 /usr/lib/perl5 /usr/share/perl5 /usr/local/lib/perl5/site_perl/5.10.0/i386-linux-thread-multi /usr/local/lib/perl5/site_perl/5.10.0 /usr/lib/perl5/vendor_perl/5.10.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.10.0 /usr/lib/perl5/vendor_perl /usr/lib/perl5/site_perl .).

3. From this command prompt you can install the perl modules.

cpan> install MIME::Entity
cpan> install MIME::Parser
cpan> install Crypt::PasswdMD5
cpan> install Term::ReadPassword
cpan> install Crypt::CBC
cpan> install Crypt::Blowfish
cpan> install Daemon::Generic
cpan> install DateTime
cpan> install SOAP::Lite
Alternative for second and third step.
# perl -MCPAN -e 'install HTML::Template'
# perl -MCPAN -e 'install MIME::Entity'
# perl -MCPAN -e 'install Crypt::PasswdMD5'
# perl -MCPAN -e 'install Term::ReadPassword'
# perl -MCPAN -e 'install Crypt::CBC'
# perl -MCPAN -e 'install Crypt::Blowfish'
# perl -MCPAN -e 'install Daemon::Generic'
# perl -MCPAN -e 'install DateTime'
