Question

Alle Ideen?

generasacodicetagpre.

Fehler:

generasacodicetagpre.

Answer 1

Versuchen Sie, diesen SQL-Befehl auszuführen:

generasacodicetagpre.

Es scheint, dass Sie Probleme mit der Verbindung mit der Verbindung mit der Datenbank haben und nicht in den Ordner schreiben, den Sie erwähnt haben.

Vergewissern Sie sich auch, dass Sie dem generationspflichtigen FILE an den Benutzer generationspoLDICETAGCODE gewährt haben.

generasacodicetagpre.

Answer 2

Honestly I didnt bother to deal with the grants and this worked even without the privileges:

echo "select * from employee" | mysql --host=HOST --port=PORT --user=UserName --password=Password DATABASE.SCHEMA > output.txt

Answer 3

As @fijaaron says,

1. GRANT ALL does not imply GRANT FILE
2. GRANT FILE only works with *.*

So do

GRANT FILE ON *.* TO user;

Answer 4

Since cP/WHM took away the ability to modify User privileges as root in PHPMyAdmin, you have to use the command line to:

mysql>  GRANT FILE ON *.* TO 'user'@'localhost';

Step 2 is to allow that user to dump a file in a specific folder. There are a few ways to do this but I ended up putting a folder in :

/home/user/tmp/db

and

chown mysql:mysql /home/user/tmp/db

That allows the mysql user to write the file. As previous posters have said, you can use the MySQL temp folder too, I don't suppose it really matters but you definitely don't want to make it 0777 permission (world-writeable) unless you want the world to see your data. There is a potential problem if you want to rinse-repeat the process as INTO OUTFILE won't work if the file exists. If your files are owned by a different user then just trying to unlink($file) won't work. If you're like me (paranoid about 0777) then you can set your target directory using:

chmod($dir,0777)

just prior to doing the SQL command, then

chmod($dir,0755)

immediately after, followed by unlink(file) to delete the file. This keeps it all running under your web user and no need to invoke the mysql user.

Answer 5

I tried all the solutions but it still wasn't sufficient. After some more digging I eventually found I had also to set the 'file_priv' flag, and restart mysql.

To resume :

Grant the privileges :

> GRANT ALL PRIVILEGES
  ON my_database.* 
  to 'my_user'@'localhost';

> GRANT FILE ON *.* TO my_user;

> FLUSH PRIVILEGES; 

Set the flag :

> UPDATE mysql.user SET File_priv = 'Y' WHERE user='my_user' AND host='localhost';

Finally restart the mysql server:

$ sudo service mysql restart

After that, I could write into the secure_file_priv directory. For me it was /var/lib/mysql-files/, but you can check it with the following command :

> SHOW VARIABLES LIKE "secure_file_priv";

Answer 6

For future readers, one easy way is as follows if they wish to export in bulk using bash,

akshay@ideapad:/tmp$ mysql -u someuser -p test -e "select * from offices"
Enter password:

If you're exporting by non-root user then set permission like below

root@ideapad:/tmp# mysql -u root -p
MariaDB[(none)]> UPDATE mysql.user SET File_priv = 'Y' WHERE user='someuser' AND host='localhost';

Restart or Reload mysqld

akshay@ideapad:/tmp$ sudo su
root@ideapad:/tmp#  systemctl restart mariadb

Sample code snippet

akshay@ideapad:/tmp$ cat test.sh 
#!/usr/bin/env bash

user="someuser"
password="password"
database="test"

mysql -u"$user" -p"$password" "$database" <<EOF
SELECT * 
INTO OUTFILE '/tmp/csvs/offices.csv' 
FIELDS TERMINATED BY '|' 
ENCLOSED BY '"' 
LINES TERMINATED BY '\n'
FROM offices;
EOF

Execute

akshay@ideapad:/tmp$ mkdir -p /tmp/csvs
akshay@ideapad:/tmp$ chmod +x test.sh
akshay@ideapad:/tmp$ ./test.sh 
akshay@ideapad:/tmp$ cat /tmp/csvs/offices.csv
