Any ideas?
SELECT * INTO OUTFILE '/home/myacnt/docs/mysqlCSVtest.csv'
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '*'
LINES TERMINATED BY '\n'
FROM tbl_property
WHERE managerGroupID = {$managerGroupID}
Error:
开发者_开发技巧Access denied for user 'asdfsdf'@'localhost' (using password: YES)
Try executing this SQL command:
> grant all privileges
on YOUR_DATABASE.*
to 'asdfsdf'@'localhost'
identified by 'your_password';
> flush privileges;
It seems that you are having issues with connecting to the database and not writing to the folder you’re mentioning.
Also, make sure you have granted FILE
to user 'asdfsdf'@'localhost'
.
> GRANT FILE ON *.* TO 'asdfsdf'@'localhost';
Honestly I didnt bother to deal with the grants and this worked even without the privileges:
echo "select * from employee" | mysql --host=HOST --port=PORT --user=UserName --password=Password DATABASE.SCHEMA > output.txt
As @fijaaron says,
GRANT ALL
does not implyGRANT FILE
GRANT FILE
only works with*.*
So do
GRANT FILE ON *.* TO user;
Since cP/WHM took away the ability to modify User privileges as root in PHPMyAdmin, you have to use the command line to:
mysql> GRANT FILE ON *.* TO 'user'@'localhost';
Step 2 is to allow that user to dump a file in a specific folder. There are a few ways to do this but I ended up putting a folder in :
/home/user/tmp/db
and
chown mysql:mysql /home/user/tmp/db
That allows the mysql user to write the file. As previous posters have said, you can use the MySQL temp folder too, I don't suppose it really matters but you definitely don't want to make it 0777 permission (world-writeable) unless you want the world to see your data. There is a potential problem if you want to rinse-repeat the process as INTO OUTFILE
won't work if the file exists. If your files are owned by a different user then just trying to unlink($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.
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";
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'

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
