Can't find file: 'file_name' (errno: 13) - How to solve MySQL error: File not found, error number: 13

Can't find file: 'file_name' (errno: 13) - How to solve MySQL error: File not found, error number: 13, specific code examples are needed

MySQL is a popular open source relational database management system that is widely used in the backend development of web applications. When using MySQL, you sometimes encounter various errors. One of the common errors is "Can't find file: 'file_name' (errno: 13)", which means that MySQL cannot find the specified file.

This error usually occurs when using the LOAD DATA INFILE statement to import data. The LOAD DATA INFILE statement uses the specified file path to load data into a MySQL table. The above error occurs when MySQL cannot find the specified file.

A common cause of this error is permission issues. When the MySQL server cannot access a file or folder, an error will be reported. Therefore, the key to solving this problem is to ensure that the MySQL server has the appropriate permissions to access the specified file.

Here are some ways to solve this problem and specific code examples:

1. Make sure the MySQL user has permission to access the file:

   • Log in to the MySQL server using the following command: mysql -u username -p
   • Grant appropriate permissions to the specified file: GRANT FILE ON . TO 'username'@'hostname';
   • Refresh permissions: FLUSH PRIVILEGES;
   • Exit MySQL shell: EXIT;

2. Before importing data, move the file to a location accessible to the MySQL server Location:

   • Create a directory on the MySQL server to store the imported file: mkdir /path/to/directory
   • Move the imported file to the newly created directory: mv /path/to/file /path/to/directory
   • Use the new file path in the LOAD DATA INFILE statement: LOAD DATA INFILE '/path/to/directory/file_name' INTO TABLE table_name;

3. Check that the file path and file name are correct:

   • Make sure the file path and file name are correct, including case and file extension.

4. Check the owner and permissions of the file:

   • In a Linux system, use the ls -l command to check the owner and permissions of the file.
   • Make sure that the MySQL server has permission to access the file. You can use the chown and chmod commands to modify the file owner and permissions.

5. Check whether the MySQL configuration file is configured correctly:

   • Open the MySQL configuration file, usually located at /etc/mysql/my.cnf or /etc /my.cnf.
   • Look for the datadir parameter and make sure it points to the correct data directory.
   • Restart the MySQL server for the changes to take effect.

The above are some common methods and specific code examples to solve the MySQL error "Can't find file: 'file_name' (errno: 13)". Choose the solution that's right for your situation, and make sure you have sufficient permissions on the operating system and MySQL server to access the files.
