How to Make MySQL Table Names Case-Insensitive on a Linux Server?

Changing MySQL Table Names to be Case Insensitive in Linux

When migrating from a Mac or Windows server to a Linux server, it is common to encounter issues with MySQL table names becoming case-sensitive. Unlike Mac and Windows, Linux is not case-insensitive by default when it comes to MySQL table names. This can cause problems with PHP scripts that use queries with varying case combinations.

One option to resolve this issue is to change the lower_case_table_names system variable from 0 to 1 in the MySQL config file. However, in Linux, this variable may be set to read-only. In that case, it is necessary to find the MySQL config file (my.cnf) and manually set the value. The specific location of the file may vary based on the Linux distribution, but it is typically found in /etc/mysql/my.cnf or /etc/my.cnf.

In the MySQL config file, locate the [mysqld] section and add the following line, if not already present:

lower_case_table_names=1

Once this line is added, restart the MySQL service to ensure the changes take effect. This will modify the storage of database and table names in lowercase on disk, causing comparisons to be case insensitive.

By modifying the lower_case_table_names variable, you can adapt the case-sensitive nature of MySQL in Linux to match the case-insensitive behavior of Windows and Mac servers, resolving the issue with table names and allowing your PHP scripts to function properly.
