In MySQL, ensuring the security of data uploads is vital. The secure_file_priv setting is a primary defense mechanism against unauthorized file uploads. This article summarizes its role and configuration.
Examples of secure_file_priv
The secure_file_priv parameter restricts file uploads to a specific directory, enhancing security. You can check the current setting with:
SHOW VARIABLES LIKE 'secure_file_priv';
For example, to use the LOAD DATA INFILE command securely:
LOAD DATA INFILE 'data.csv' INTO TABLE example_table
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\\n';
This command will only work if data.csv is in the directory specified by secure_file_priv.
