How to Make MySQL Table Names Case Insensitive in Linux

In a Linux environment, MySQL table names are case sensitive, unlike Mac and Windows servers. This can cause problems when migrating websites that use different case combinations for table names.

Solution: Modifying the lower_case_table_names Variable

To change the default case sensitivity, modify the lower_case_table_names system variable in the MySQL config file. Set it to 1, which instructs MySQL to store table names in lowercase and perform case-insensitive comparisons. This behavior emulates the case insensitivity of Mac and Windows systems.

Steps to Modify the Variable:

1. Locate the MySQL config file (typically named my.cnf).
2. Open the file and add the following line:

lower_case_table_names = 1

3. Save the changes and restart the MySQL server.

Important Note:

Avoid setting lower_case_table_names to 0 on case-insensitive file systems like Windows or Mac OS X. This can result in index corruption. Instead, set it to 1 to ensure proper table name handling. By implementing this solution, you can restore case-insensitive table name handling and resolve any issues caused by the migration.
