SQLSTATE [HY000]：一般錯誤：1 無法創建/寫入文件'/var/www/html/new_7alaqa/public/dumpfiles/15869372079790_1036teachernote.txt'

Question

文件夾 /var/www/html/new_7alaqa/public/dumpfiles/ 歸 mysql:mysql 所有，我正在嘗試運行：

$note_file= time().$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);

編輯：來自 mysql 命令：在 /tmp 目錄和默認目錄中工作

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)
mysql> select * from users  into outfile '/tmp/11.txt';
Query OK, 1417 rows affected (0.00 sec)

Answer 1

根據您設置的服務器/數據庫/用戶帳戶，可以嘗試以下操作：

1. 嘗試將dumpfiles的所有者更改為www-data ：

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

您可以通過運行恢復

sudo chown -R mysql:mysql dumpfiles

2. 將FILE權限授予您的 MySQL 用戶。

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

請務必注意，即使您已經通過運行GRANT ALL授予用戶所有權限，它也不包括FILE權限。

3. 嘗試 escaping 路徑：

$dumpFilePath = addslashes('/var/www/html/new_7alaqa/public/dumpfiles/$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(';";
