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.

    Unfortunately, this does not work with MySQL 8.0 anymore. It has to be set before initialization. Jul 23, 2020 at 14:25
  • I have installed the mysql as a contener with podman. As it turned out it has Oracle Linux Server 8.8 and mysql 8.1.0. I needed to install vim (microdnf install -y vim) if I wanted a more powerful editor than cat and sed. But other answers suggest that it will be a pain. Nov 10, 2023 at 10:55

If you change lower_case_table_names in a DB with existing tables Stack Overflow: 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... :


  • stand alone mysql server :


Afterwards restart MySQL server, and everything will be ok.
