installing Vmware SDK on Centos 8

[danielheaton]

Hi guys

We've got a Centos 8 VM in AWS EC2 on which we're trying to install the VMWare vSphere Perl SDK 7

When running the installer we get some dependency issues

Code: Select all

[root@my-aws-nagios-box vmware-vsphere-cli-distrib]# ./vmware-install.pl EULA_AGREED=yes
Creating a new vSphere CLI installer database using the tar4 format.
Installing vSphere CLI 7.0.0 build-16453907 for Linux.

CPAN not able to install following Perl modules on the system. These must be 
installed manually for use by vSphere CLI:
Crypt::SSLeay 0.72 or newer 
UUID 0.27 or newer 
Net::INET6Glue 0.603 or newer 

And when checking cpan we get confirmation that those modules are already installed and up to date

Code: Select all

[root@my-aws-nagios-box vmware-vsphere-cli-distrib]# cpan -i Module::Build Crypt::SSLeay UUID Net::INET6Glue

Crypt::SSLeay is up to date (0.72).
UUID is up to date (0.28).
Net::INET6Glue is up to date (0.603).

Might there be other dependencies not listed here?

Thanks!

This is a bug with Crypt::SSLeay package with EL8 that VMWare's perl SDK uses, the same thing occurs on my EL8 system, this is why:

Code: Select all

Can't load '/usr/local/lib64/perl5/auto/Crypt/SSLeay/SSLeay.so' for module Crypt::SSLeay: /usr/local/lib64/perl5/auto/Crypt/SSLeay/SSLeay.so: undefined symbol: SSLv2_client_method at /usr/lib64/perl5/DynaLoader.pm line 193.

This is the check it's using to determine if you have it installed:

Code: Select all

perl -MCrypt::SSLeay -e 1

So it's technically not really installed.

The issue is that CPAN is unable to build the Crypt::SSLeay module so it's not technically installed/or compatible with the EL8 openssl version.

I was able to get it to work by doing this (NOTE: This installs a unreleased version of Crypt::SSLeay from their github and hasn't been tested):

Code: Select all

cd /tmp
yum install -y libxml2-devel libxml2 libuuid-devel perl-XML-LibXML perl-Env
yum remove perl-Crypt-SSLeay -y
wget https://github.com/nanis/Crypt-SSLeay/archive/0.73_04.zip
unzip 0.73_04.zip
cpan -i IO::Interactive::Tiny
cd Crypt-SSLeay-0.73_04
sed -i 's/inc::IO/IO/' Makefile.PL
perl Makefile.PL
make
make install

Then re-run the vsphere perl SDK install and worked.

Thank you! We managed to get a working version (slightly different to yours - 073_06) by running with

Code: Select all

cpanm Crypt::SSLeay --dev

All working happily now, thanks for your help!
