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.

- 2 MySQL, ODBC with OpenOffice Setup on the Remote Server
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-endsAUR AUR or the commandline.
mysqladmin -h localhost -u root -p create test
Testing the ODBC
To test the ODBC connection
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
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.
To work around error messages this URL proved helpful so here it is as well.
MySQL, ODBC with OpenOffice Setup on the Remote Server
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 /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
command and you should be able to log into your server.
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.
