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 [http://www.unixodbc.org/ 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===
 
On my machine I run phpmyadmin so I already had a test database to use. If you do not have a test database then
 
create one in MySQL.
 
 
 
===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                                  |
 
|                                      |
 
+---------------------------------------+
 
SQL>
 
 
 
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          = /tmp/mysql.sock
 
Option          =
 
Stmt            =
 
 
 
===Edit my.cnf===
 
Edit /etc/my.cnf so that port 3306 will be running to do this comment out skip-networking and also add
 
bind-address = your IP
 
#skip-networking
 
bind-address =192.168.0.100
 
 
 
===Verify Port 3306 is Listening===
 
restart the mysql server with the command "/etc/rc.d/mysqld restart" and then check to see that port 3306 is listening
 
on the server
 
netstat -ant
 
 
 
If port 3306 is open, you'll see the following
 
Active Internet connections (servers and established)
 
Proto Recv-Q Send-Q Local Address          Foreign Address        State
 
tcp        0      0 0.0.0.0:3306          0.0.0.0:*              LISTEN
 
 
 
===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 -u "username" -p" and log into you MySQL
 
mysql> CREATE DATABASE test;
 
mysql> GRANT ALL ON test.* TO username@'192.168.0.101' IDENTIFIED BY 'PASSWORD';
 
 
 
http://www.cyberciti.biz/nixcraft/vivek/blogger/2006/03/how-do-i-enable-remote-access-to-mysql.php
 
 
 
Here was a helpful URL for this step.
 
 
 
===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 192.168.0.102 3306
 
 
 
Good luck and happy computing now that you can get OpenOffice to connect to you databases.
