How to Install Perl in CentOS 6.2

When you try to install the rpm packages that was depend on the perl, you will get this error. The best practice is to check up if perl is already installed on your server before start the installation for the software that depend on perl to run.

Symptom :

[root@centos6 ~]# rpm -U webmin-1.570-1.noarch.rpm
warning: webmin-1.570-1.noarch.rpm: Header V3 DSA/SHA1 Signature, key ID 11f63c51: NOKEY
error: Failed dependencies:
        /usr/bin/perl is needed by webmin-1.570-1.noarch

This is how you fix this problem. This command will install the perl and the dependencies.

[root@centos6 ~]# yum install perl
