Question

Folder /var/www/html/new_7alaqa/public/dumpfiles/ owned by mysql:mysql and i'm trying to run:

$note_file= time().$user_idd."_".$halaqa_idd.$typed."note.txt";
$note_query="select * from notes where is_deleted = 0 and halaqa_id=".$halaqa_idd."  into outfile '/var/www/html/new_7alaqa/public/dumpfiles/$note_file' FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '),\n(';";

DB::select($note_query);

Edit: from mysql commands: working in /tmp directory and default directory

select * from users  into outfile '/var/www/html/new_7alaqa/public/dumpfiles/11.txt';
ERROR 1 (HY000): Can't create/write to file '/var/www/html/new_7alaqa/public/dumpfiles/11.txt' (Errcode: 13 - Permission denied)

Answer 1

Depending on your server/db/user accounts set up, here are some things to try:

1. Try changing the owner of dumpfiles to www-data :

sudo chown -R www-data:www-data dumpfiles

You can revert by running

sudo chown -R mysql:mysql dumpfiles

2. Give FILE permission to your MySQL user.

GRANT FILE ON *.* TO user;
FLUSH PRIVILEGES;

It's important to note that even if you already gave your user all permissions by running GRANT ALL , it doesn't include the FILE permission.

3. Try escaping the path:

$dumpFilePath = addslashes('/var/www/html/new_7alaqa/public/dumpfiles/$note_file');
$note_query="select * from notes where is_deleted = 0 and halaqa_id=".$halaqa_idd."  into outfile '$dumpFilePath' FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '),\n(';";
