1 - Summary

This guide will show how to install the Microsoft ODBC driver for SQL Server in
Red Hat Enterprise Linux. This has been tested in Red Hat Enterprise Linux 6
(x86_64).


2 - System variables

Log in as a normal user. Add these lines to /etc/profile. This will set the
variables on system start up.
  ODBCSYSINI=/etc
  ODBCINI=/etc/odbc.ini
  export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE ODBCSYSINI ODBCINI INPUTRC LD_LIBRARY_PATH
# sudo cp /etc/profile /etc/profile.example
[sudo] password for testuser:
# sudo vi /etc/profile
[sudo] password for testuser:

Set the following variables as the root user.
# su - root
Password:
# ODBCSYSINI=/etc
# echo $ODBCSYSINI
/etc
# ODBCINI=/etc/odbc.ini
# echo $ODBCINI
/etc/odbc.ini
# logout


3 - Driver installation

Download the driver from Microsoft and then install it. Here are some links.

# mkdir odbc_mssql
# cd odbc_mssql/
# wget http://.../msodbcsql-11.0.2270.0.tar.gz
# tar -zxvf msodbcsql-11.0.2270.0.tar.gz
# cd msodbcsql-11.0.2270.0/
# ./build_dm.sh
# cd /tmp/unixODBC.12188.19504.88/unixODBC-2.3.0/
# sudo make install
[sudo] password for testuser:
# cd ~/msodbcsql-11.0.2270.0/
# odbc_config --odbcinstini
/etc/odbcinst.ini
# ./install.sh verify

4 - ODBC configuration

One or more steps may have an *. See README for more information regarding
these steps.
# sudo cp /etc/odbcinst.ini /etc/odbcinst.ini.example
[sudo] password for testuser:
# sudo ./install.sh install
[sudo] password for testuser:
# odbcinst -q -d -n "ODBC Driver 11 for SQL Server"

Here is an example entry that will use the ODBC driver for SQL Server.
  [testdb]
  Driver          = ODBC Driver 11 for SQL Server
  Trace           = Yes
  Server          = X.X.X.X
  Port            = 1433
  Database        = testdb
# sudo vi /etc/odbc.ini
[sudo] password for testuser:


5 - ODBC testing

Test out the ODBC connection.
# isql -v testdb $username $password
SQL> select count(*) from testtable;
SQL> quit
