load records into mysql table from csv - mysql

Question

I'm running mysql v8.0.24 on ubuntu server. I have created a table called uranium in the database stocks. I'm now trying to run the command below in mysql as root, to load records from a csv on the server into the table. I'm getting the error below, does anyone see what the issue might be and can you suggest how to fix it?
code:
LOAD DATA INFILE '/home/user/uranium.csv' INTO TABLE stocks.uranium FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 1 ROWS;
error:
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

Answer 1

By default MySQL has secure_file_priv set, which restricts the directories that it will access for INFILE and OUTFILE operations. You can set the MySQL configuration to allow a nominated folder by editing the [mysqld] section of mysql.cnf*.
Ubuntu also has AppArmor running, that will prevent MySQL from seeing the file even if it has the correct permissions. You will need to update that too.
For this reason I recommend you create a dedicated directory for this sort of import, rather than using a home directory. For the purposes of this answer I have use /sqlfiles.
For Ubuntu and other Debian derived versions of Linux, go to /etc/mysql/mysql.conf.d
Using your favourite editor, edit the file mysql.cnf that you find there. (There are other files with the same name elsewhere in the /etc/mysql directory. Make sure you're editing the correct one)
At the end of the [mysqld] section add the line
secure-file-priv=/sqlfiles
Save the file, then create the folder and set the ownership to mysql
sudo mkdir /sqlfiles
sudo chown mysql:mysql /sqlfiles
Now update the AppArmor profile. Go to /etc/apparmor.d/local and edit the file usr.sbin.mysqld. Add these lines to the end of that file:
/sqlfiles/ r,
/sqlfiles/** rwk,
Finally, restart AppArmor
sudo service apparmor restart
This is working on my development server running Ubuntu 20.04, MySQL 8.0.24
Good luck!
* If you create the entry in mysql.cnf but leave the filename blank you will disable the effect of the variable, and MySQL will read or write to any folder. AppArmor will still prevent access unless you update that too.

Answer 2

Look at this answer
In spite the fact that your csv file is located on the server's file system, I think you should include LOCAL keyword:
LOAD DATA LOCAL INFILE ...
Or
The file has to be located in the database directory or have world
read permissions, and the client username must have the FILE
privilege.
I think your csv file is not
...located in the database directory or have world read permissions...
Note that
...client username must have the FILE privilege...
MySql8 documentation: doc and doc
LOAD DATA INFILE gets the file from the database server's local
filesystem. The file has to be located in the database directory or
have world read permissions, and the client username must have the
FILE privilege.
LOAD DATA LOCAL INFILE reads the file on the client, and sends the
contents to the server.
You can find more details in the documentation.
And
If LOCAL is specified, the file is read by the client program on the client host and sent to the server.
If LOCAL is not specified, the file must be located on the server host and is read directly by the server.
