Next set up your "odbc.ini" and ".odbc.ini" file. It should be pointed out here that the ".odbc.ini" file is just like the "odbc.ini" file except that it is a file that gets saved in the user's home dir (i.e a hidden file).

Next set up your data sources in "/etc/odbc.ini" (system wide) or "~/.odbc" (current user). If a data source is defined in both of these files, the one in your home directory take precedence.

Template:Moveto

Open Database Connectivity, commonly ODBC, is an open specification for providing application developers with a predictable API with which to access Data Sources

This document shows how to set up unixODBC in Arch, first to access your database on your localhost and then extends the steps to configure MySQL to allow remote access through ODBC.

MySQL, ODBC with OpenOffice Setup on LocalHost

Packages To Install

Start by installing the unixodbc and myodbc

# pacman -S unixodbc myodbc

Configure the ini Files

Configure the "odbc.ini" and "odbcinst.ini" file. Starting with odbcinst.ini, which lists all installed drivers. Su to root and set up your /etc/odbcinst.ini file as follows

[MySQL]
Description     = ODBC Driver for MySQL
Driver          = /usr/lib/libmyodbc.so
Setup           = /usr/lib/libodbcmyS.so
FileUsage       = 1

Next set up your data sources in "/etc/odbc.ini" (system wide) or "~/.odbc" (current user). If a data source is defined in both of these files, the one in your home directory take precedence.

[MySQL-test]
Description     = MySQL database test
Driver          = MySQL
Server          = localhost
Database        = test
Port            = 3306
Socket          = /var/run/mysqld/mysqld.sock
Option          =
Stmt            =

Create A Symbolic Link

Next we need to create a symlink for libmyodbc.so. To do this we need to go to "/usr/lib/" and set up a symlink to libmyodbc.so

 cd /usr/lib/
 ln -s ./libmyodbc5w.so ./libmyodbc.so

Create A Test Database

Create a new database "test". You can use one of the MySQL front-ends mysql-gui-toolsAUR mysql-workbenchAUR or the commandline.

mysqladmin -h localhost -u root -p create test

Testing the ODBC

To test the ODBC connection

isql MySQL-test

If the connection is established, you will see

+---------------------------------------+
| Connected!                            |
|                                       |
| sql-statement                         |
| help [tablename]                      |
| quit                                  |
|                                       |
+---------------------------------------+

If you have a problem connecting then check the error message by running

isql MySQL-test -v

A Couple Useful Websites

http://www.unixodbc.org/doc/OOoMySQL.pdf

This website got me going on ODBC with MySQL but left out some things that were necessary for me to get isql up and running. However this might be a good reference for the OpenOffice part.

http://mail.easysoft.com/pipermail/unixodbc-support/2004-August/000111.html

To work around error messages this URL proved helpful so here it is as well.

MySQL, ODBC with OpenOffice Setup on the Remote Server

Edit odbc.ini

From the Client side it is necessary to edit the odbc.ini and the .odbc.ini files slightly. Here is the odbc.ini that I used to login.

[MySQL-test]
Description     = MySQL database test
Driver          = MySQL
Server          = 192.168.0.102
Trace           = Off
TraceFile       = stderr
Database        = test
Port            = 3306
USER            = username
Password        = secretpassword
Socket          = /var/run/mysqld/mysqld.sock
Option          =
Stmt            =

Edit my.cnf

Edit /etc/mysql/my.cnf so that port 3306 will be running to do this comment out skip-networking. You can add bind-address = IP with you incoming network card's IP.

#skip-networking
bind-address = 192.168.1.100

Verify Port 3306 is Listening

restart the MySQL server

# systemctl restart mysqld

Then check that port 3306 is listening on the server

$ ss -ant

If port 3306 is open, you'll see the following:

State       Recv-Q Send-Q                                     Local Address:Port                                       Peer Address:Port
LISTEN      0            50                                                     *:3306                                                  *:*

Permissions on MySQL for Remote Connection

Next it is necessary to give permissions on the server so that MySQL will allow a remote connection. Type

mysql -h localhost -u username -p

and log into your MySQL database.

mysql> CREATE DATABASE test;
mysql> GRANT ALL ON test.* TO username@'192.168.1.100' IDENTIFIED BY 'PASSWORD';

An extensive tutorial on this subject can be found here.

Testing the ODBC

run the

isql MySQL-test

command and you should be able to log into your server.

Miscellaneous

From the client you can run the following command to verify that port 3306 is open

telnet 192.168.0.100 3306

Good luck and happy computing now that you can get OpenOffice to connect to you databases.
