This command downloads and installs Perl from the YUM repository:

# cd ~

# sudo yum install perl

Force LiteSpeed to Update to Latest Version on cPanel/WHM Server

Sometimes you find out that LiteSpeed won’t update to the latest version automatically. The worst is you can’t see the option to update to the latest version, although LiteSpeed has released a new version.
This happened to me when I’m using LiteSpeed version 4.1.3. LiteSpeed version 4.2 was released for about a montha but yes I can’t update it.
If you’re facing similar situation, you can update to the latest version, simply issue the following command in SSH as root.

/usr/local/lsws/admin/misc/lsup.sh -f -v 4.2

Replace 4.2 to latest version that is currently available.
