5. OTRS dependency to check using perl script:-
OTRS is written in Perl, it uses a number of Perl modules. We can check for missing modules by using the CheckModules.pl script included with OTRS.
sudo /opt/otrs/bin/otrs.CheckModules.pl
We have to install the dependency packages which are displayed as not installed. Please find the below command to install the above not installed packages.
yum install "perl(Apache2::Reload)" "perl(Crypt::Eksblowfish::Bcrypt)" "perl(Encode::HanExtra)" "perl(JSON::XS)" "perl(Mail::IMAPClient)" "perl(ModPerl::Util)" "perl(Text::CSV_XS)" "perl(YAML::XS)" "perl(DBD::Pg)" "yum install "perl(DBD::mysql)"
Again run the perl script sudo /opt/otrs/bin/otrs.CheckModules.pl
