=MySQL, ODBC with OpenOffice Setup on LocalHost=
#REDIRECT [[Open Database Connectivity]]
This document shows how to set up ODBC in Arch, first to access you database on your localhost and then extends the steps to configure MySQL to allow remote access through ODBC.
==Packages To Install==
Start by installing the unixodbc and myodbc
# pacman -Sy unixodbc
# pacman -Sy myodbc
==Configure Your ini Files==
Configure your "odbc.ini", ".odbc.ini", and "odbcinst.ini" file.
Startinig with odbcinst.ini, Su to root and set up your /etc/odbcinst.ini file as follows
Description    = ODBC Driver for MySQL
Driver          = /usr/lib/libmyodbc.so
Setup          = /usr/lib/libodbcmyS.so
FileUsage      = 1
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).
Description    = MySQL database test
Driver          = MySQL
Server          = localhost
atabase        = test
Port            = 3306
Socket          = /tmp/mysql.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/myodbc3-3.51.12.so or
whatever the version of the module is and set up a symlink to libmyodbc.so
ln -s /usr/lib/libmyodbc3-3.51.12.so ./libmyodbc.so
==Renamed Modules==
OK, for this step I cheap-skated it a little and simply copy these files to agree with version of ODBC that Arch
was looking for.
cp libssl.so.0.9.8 libssl.so.0.9.7
cp libcrypto.so.0.9.8 libcrypto.so.0.9.7
==Test Datbase==
On my machine I run phpmyadmin so I already had a test database to use. If you don't 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                                  |
|                                      |
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=
==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
bind-address =
==Edit hosts.allow==
Next add a line in "hosts.allow"
Although it is recommended to do something like mysql: or whatever your client
machine would be.
==Verify Port 3360 is Listening==
restart with the command "/etc/rc.d/mysqld restart" and then check to see that port 3306 is listening
on the server
netstat -ant
==Permissions on MySQL for Remote Connection==
Next it is neccesary to give permissions on the server so that MySQL will allow a remote connection.
mysql -u "username" -p
mysql> GRANT ALL ON foo.* TO username@'' IDENTIFIED BY 'PASSWORD';
3) grant permission to individual IP in mysql
Grant access to new database
If you want to add new database called foo for user bar and remote IP then you need to type following commands at mysql> prompt:
Grant access to existing database
Let us assume that you are always making connection from remote IP called for database called webdb for user webadmin then you need to grant access to this IP address. At mysql> prompt type following command for existing database:
mysql> update db set Host='' where Db='webdb';
mysql> update user set Host='' where user='webadmin';
From remote system type command:
$ mysql -u webadmin –h –p
You can also use telnet to connect to port 3306 for testing purpose:
$ telnet 3306
