I am using Ubuntu 13.10 and MySQL 5.6 and I know database name and table name are case sensitive in Ubuntu (and some other *nix environments) by default.

Now, I want to make MySQL work as case insensitive in Ubuntu.

Is it possible? If yes, how can I do it?

Open terminal and edit /etc/mysql/my.cnf

sudo nano /etc/mysql/my.cnf

Underneath the [mysqld] section.add:

lower_case_table_names = 1

Restart mysql

sudo /etc/init.d/mysql restart

Then check it here:

mysqladmin -u root -p variables

    You have to add this section if it is not available. Otherwise the restart will fail. – alexander Mar 26 '17 at 18:44

If you change lower_case_table_names in a DB with existing tables MySQL > Table doesn't exist. But it does (or it should) can happen.

The comment to this answer helped me in this case:

I reverted the value, restarted the database, exported the tables, set the value back to 1, restarted the database, re-imported the tables and everything worked again.

This problem was causing pain for me, where Doctrine generated capital/CamelCase table names and MySQL stored them as lowercase!

It was solved by changing my.cnf and adding

lower_case_table_names = 1

under the [mysqld] section

my.cnf can be found:

  • under LAMPP/XAMPP... :

    /opt/lampp/etc/my.cnf

  • stand alone mysql server :

    /etc/mysql/my.cnf

Afterwards restart MySQL server, and everything will be ok.
