Can't create a database link for CMS WebGUI - sql-server

Question

I've updated the whole scenario (last one was a conflict between i686 and x64 libraries)
Now I have an VPS with a fresh CentOS 6.6 32 bit with unixODBC, FreeTDS and WebGUI installed
I can connect perfectly with SQL Server 2008 through isql and perl scripts.
BUT my goal is to create a database link for WebGUI (an open-source CMS based in perl)
Output for odbcinst -j
unixODBC 2.3.4
DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /root/.odbc.ini

Driver=FreeTDS
Server=XX.XX.XX.XX
Database=myDatabase
Port=1433 #sql server default port
TDS_Version=7.3
Trace=Yes
TraceFile=/tmp/sql.log
When I execute this perl script, it runs ok.
#!/usr/bin/perl
use strict;
use warnings;
use DBI;
use DBD::ODBC;
my $dsn = "DBI:ODBC:DSN"; # Same DSN as above
my $db_user = "dbuser";
my $db_pass = 'dbpass';
my $dbh = DBI->connect($dsn, $db_user, $db_pass) or die "$DBI::errstr\n";
print "Connected\n";
my $query = "Select * from myTable";
my $sth = $dbh->prepare($query) or die "$DBI::errstr\n";
$sth->execute or die "$DBI::errstr\n";
# go do stuff!
# Close the database
$sth->finish;
$dbh->disconnect;
This is the database link I'm trying to add to WebGUI
When I commit the changes, I get this error in my browser:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /home.
Reason: Error reading from remote server

Maybe WebGUI is trying to load the /home from SQL Server instead of mysql? (I just want to connect to SQL Server to fetch some products, nothing else)
Any help would be appreciated

Answer 1

Try: export LD_LIBRARY_PATH=/usr/local/lib

Answer 2

In your odbc.ini, you specify the DRIVER defined in odbcinst.ini.
Try this for odbc.ini:
[DSN]
Description=DNS description
Driver=FreeTDS
Server=XX.XX.XX.XX
Database=myDatabase
Port=1433 #sql server default port
TDS_Version=7.3
Also, be sure you use the right TDS Version for the SQL Server version and FreeTDS version you're using. I'd recommend sticking with 7.2 unless you need 7.3: http://www.freetds.org/userguide/choosingtdsprotocol.htm I've got example odbc.ini, odbcinst.ini and freetds.conf files in this repo, if they help: https://github.com/FlipperPA/django-python3-vagrant/tree/master/examples
Good luck!

Answer 3

OK, just added
use DBD::ODBC;
to the file SQL.pm and WebGUI is able to recognize unixODBC (and FreeTDS, too).
Merry X'Mas!!! :D
