Migrate OTRS from RH5 to RH7

[samguo]

Hi Everyone
I am migrating OTRS form redhat 5 to redhat 7, I followed this guide to get file to new server.
https://www.claudiokuenzler.com/blog/40 ... I618rZ94W8

My database is installed on seperate server, so when I run /opt/otrs/bin/otrs.CheckDB.pl it give me follow error message

Can't locate Data/Dumper.pm in @INC (@INC contains: /opt/otrs/Custom /opt/otrs/Kernel/cpan-lib /opt/otrs /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /opt/otrs/Kernel/System/Main.pm line 18.
BEGIN failed--compilation aborted at /opt/otrs/Kernel/System/Main.pm line 18.
Compilation failed in require at /opt/otrs/bin/otrs.CheckDB.pl line 40.
BEGIN failed--compilation aborted at /opt/otrs/bin/otrs.CheckDB.pl line 40.

I assume that is because I didnt have enough perl module installed, so I did following commend to install missing modules

yum install `/opt/otrs/bin/otrs.CheckModules.pl | grep 'Not installed' | sed 's/^ *o //;s/\.\.\..*//;s/\(.*\)/"perl\(\1\)"/' | tr '\n' ' '`

but I got following error

defined(@array) is deprecated at /opt/otrs/Kernel/cpan-lib/CGI.pm line 528.
(Maybe you should just omit the defined()?)

Find the work around solution
if you run yum install "perl (xxxxxxx)" one by one manually, system can find the required packet.
seems stupid but it work. anyone know why?

I've no idea why. And I would never follow the instruction you did because for RHEL/CentOS there are well maintained RPMs available. With

Code: Select all

yum install http://ftp.otrs.org/pub/otrs/RPMS/rhel/7/otrs-5.0.16-01.noarch.rpm

the latest OTRS 5 will be installed with the most dependencies - including adding the user. After this, only the configuration filles needs to be copied, the database imported and packages reinstalled and you're almost done.
