Today i upgraded Perl on Cpanel server. The version of perl installed on the server was

[root@host scripts]# perl -v

This is perl, v5.8.0 built for i386-linux-thread-multi

You can download latest version of Perl from Cpanel web site

http://layer1.cpanel.net

Latest version of perl available now is

http://layer1.cpanel.net/perl588installer.tar.gz

So lets download it

cd /usr/local/src
wget http://layer1.cpanel.net/perl588installer.tar.gz

Untar it

tar -zxvf perl588installer.tar.gz

Go to perl folder

cd perl588installer

Run install

./install

After Upgrade

[root@host perl588installer]# perl -v

This is perl, v5.8.8 built for i686-linux

Now we need to check if all perl modules are properly installed, then upgrade cpanel with upcp.

/scripts/checkperlmodules
/scripts/upcp --force
