MySQL case sensitive table names on Linux

سؤال
Moving a MySQL database from Windows to Linux I have the problem that on Linux the names of the tables are case sensitive. This is a problem, because the Java application that I am developing can't find tables.
I have changed my /etc/mysql/my.cnf
file adding the row:
lower_case_table_names=1
But that did not change anything.
My server version is:
5.1.61-0ubuntu0.11.10.1 (Ubuntu)
How can I configure MySQL to ignore case in table names?

Just altering the lower_case_table_names setting isn't enough. It needs to be done before you import your database(s).
The MySQL 5.1 documentation lists a procedure for moving between Windows and Linux/UNIX. This will ensure that your desired rules for enforcing case sensitivity are followed. Take a look and verify that you did these steps in the correct order:
To convert one or more entire databases, dump them before setting lower_case_table_names, then drop the databases, and reload them after setting lower_case_table_names:
1 - Use mysqldump to dump each database:
mysqldump --databases db1 > db1.sql
mysqldump --databases db2 > db2.sql
... Do this for each database that must be recreated.
2 - Use DROP DATABASE to drop each database.
3 - Stop the server, set
lower_case_table_names
in the[mysqld]
section of your\etc\mysql\my.cnf
file, and restart the server.4 - Reload the dump file for each database. Because lower_case_table_names is set, each database and table name will be converted to lowercase as it is recreated:
mysql < db1.sql
mysql < db2.sql

File in etc/my.cnf Find this # The MySQL server [mysqld] and set lower_case_table_names = 1
There is no need to drop db. It works so first check with this. Reason is default value of lower_case_table_names =1 for Windows.
