Access denied; you need (at least one of) the SUPER privilege(s) for this operation

Question

So I try to import sql file into rds (1G MEM, 1 CPU). The sql file is like 1.4G

mysql -h xxxx.rds.amazonaws.com -u user -ppass --max-allowed-packet=33554432 db < db.sql

It got stuck at:

ERROR 1227 (42000) at line 374: Access denied; you need (at least one of) the SUPER privilege(s) for this operation

The actual sql content is:

/*!50003 CREATE*/ /*!50017 DEFINER=`another_user`@`1.2.3.4`*/ /*!50003 TRIGGER `change_log_BINS` BEFORE INSERT ON `change_log` FOR EACH ROW
IF (NEW.created_at IS NULL OR NEW.created_at = '00-00-00 00:00:00' OR NEW.created_at = '') THEN
        SET NEW.created_at = NOW();
END IF */;;

another_user is not existed in rds, so I do:

GRANT ALL PRIVILEGES ON db.* TO another_user@'localhost';

Still no luck.

Answer 1

Either remove the DEFINER=.. statement from your sqldump file, or replace the user values with CURRENT_USER.

The MySQL server provided by RDS does not allow a DEFINER syntax for another user (in my experience).

You can use a sed script to remove them from the file:

sed 's/\sDEFINER=`[^`]*`@`[^`]*`//g' -i oldfile.sql

Maximomaximum

You're correct. The reason it doesn't work is that specifying another user as DEFINER when the logged-in user does not have the SUPER privilege (which itself is not allowed in RDS) would allow arbitrary privilege escalation -- stored programs run with the credentials and privileges of their DEFINER (as opposed to those of the calling user -- their INVOKER), by default. Also at Server Fault. – Huppert

For some reason I had to use * instead of +: sed 's/\sDEFINER=`[^`]*`@`[^`]*`//' -i oldfile.sql – Fugato

The + is not valid in standard sed. sed -E also works, but I don't see any harm in changing it to * anyway. – Senator

is there any faster option ? sed is kind of slow if the sql file is very big – Parve

@Parve You can try awk which might be a little faster than sed – Maximomaximum

if it easy/fast for you ... do you mind improve your answer adding an awk example too ? – Parve

@Parve I haven't used awk much. I just read online here that sed is slower than awk. – Maximomaximum

This solution worked perfectly for me. Another potential solution from aws doc: aws.amazon.com/premiumsupport/knowledge-center/… – Neurovascular

The RDS export I had had double quotes instead of backticks. /s\sDEFINER="[^]*"@"[^]*"//g works on this type. – Metastasis

@trainoasis osx uses a different version of sed/grep etc. tools. Please check the man pages for relevant commands in osx sed. – Maximomaximum

For some reason the sed.exe that comes with Git Bash tools doesn't seem to like character classes - to get around this I used this regex instead: sed 's/ DEFINER=`\w*`@`\w*`//g' -i oldfile.sql – Granados

Answer 2

Remove the 3 lines below if they're there, or comment them out with -- :

At the start:

-- SET @@SESSION.SQL_LOG_BIN= 0;
-- SET @@GLOBAL.GTID_PURGED=/*!80000 '+'*/ '';

At the end:

-- SET @@SESSION.SQL_LOG_BIN = @MYSQLDUMP_TEMP_LOG_BIN;

Note that the comment characters are "dash dash space" including the space.

A better solution is to stop these lines from being written to the dump file at all by including the option --set-gtid-purged=OFF on your mysqldump command.

Foy

You can prevent these by adding --set-gtid-purged=OFF to your mysqldump command. Found here: stackoverflow.com/a/56251925 – Grecism

@IllyaMoskvin this is what worked for me. Upon Date Export in my sql workbench --> Advanced Options --> set-gtid-purged - Add 'SET @@GLOBAL.GTID_PURGED' to the output --> set to "OFF" – Disjoined

I get mysqldump: unknown variable 'set-gtid-purged=OFF' in MariaDB 10.3 – Peashooter

This solution worked perfect for me on mysql8 hosted on AWS RDS. Thanks – Landy

Answer 3

Another useful trick is to invoke mysqldump with the option --set-gtid-purged=OFF which does not write the following lines to the output file:

SET @@SESSION.SQL_LOG_BIN= 0;
SET @@GLOBAL.GTID_PURGED=/*!80000 '+'*/ '';
SET @@SESSION.SQL_LOG_BIN = @MYSQLDUMP_TEMP_LOG_BIN;

not sure about the DEFINER one.

Bk

Thank you. In my case I ran SET @@GLOBAL.GTID_MODE = OFF; in MySql Workbench in the exporting side from source database – Asphodel

I have deleted these two lines from the dump file then it works for me --SET @@SESSION.SQL_LOG_BIN= 0; SET @@GLOBAL.GTID_PURGED=/*!80000 '+'*/ ''; – Emanuelemanuela

thank you. I solved it by specifying --set-gtid-purged=OFF in MySQL Workbench. – Snoddy

Answer 4

When we create a new RDS DB instance, the default master user is not the root user. But only gets certain privileges for that DB instance. This permission does not include SET permission. Now if your default master user tries to execute mysql SET commands, then you will face this error: Access denied; you need (at least one of) the SUPER or SYSTEM_VARIABLES_ADMIN privilege(s) for this operation

Solution 1

Comment out or remove these lines

SET @MYSQLDUMP_TEMP_LOG_BIN = @@SESSION.SQL_LOG_BIN;
SET @@SESSION.SQL_LOG_BIN= 1;
SET @@GLOBAL.GTID_PURGED=/*!80000 '+'*/ '';

Solution 2

You can also ignore the errors by using the -f option to load the rest of the dump file.

mysql -f <REPLACE_DB_NAME> -u <REPLACE_DB_USER> -h <DB_HOST_HERE> -p < dumpfile.sql

Houseman

Solution 2 works well if you are piping a mysqldump to a new database – Councilman

Answer 5

Just a MacOS extra update for hjpotter92 answer.

To make sed recognize the pattern in MacOS, you'll have to add a backslash before the = sign, like this:

sed -i old 's/\DEFINER\=`[^`]*`@`[^`]*`//g' file.sql

Answer 6

Problem: You're trying to import data (using mysqldump file) to your mysql database ,but it seems you don't have permission to perform that operation.

Solution: Assuming you data is migrated ,seeded and updated in your mysql database, take snapshot using mysqldump and export it to file

mysqldump -u [username] -p [databaseName] --set-gtid-purged=OFF > [filename].sql

From mysql documentation:

GTID - A global transaction identifier (GTID) is a unique identifier created and associated with each transaction committed on the server of origin (master). This identifier is unique not only to the server on which it originated, but is unique across all servers in a given replication setup. There is a 1-to-1 mapping between all transactions and all GTIDs.

--set-gtid-purged=OFF SET @@GLOBAL.gtid_purged is not added to the output, and SET @@SESSION.sql_log_bin=0 is not added to the output. For a server where GTIDs are not in use, use this option or AUTO. Only use this option for a server where GTIDs are in use if you are sure that the required GTID set is already present in gtid_purged on the target server and should not be changed, or if you plan to identify and add any missing GTIDs manually.

Afterwards connect to your mysql with user root ,give permissions , flush them ,and verify that your user privileges were updated correctly.

mysql -u root -p
UPDATE mysql.user SET Super_Priv='Y' WHERE user='johnDoe' AND host='%';
FLUSH PRIVILEGES;
mysql> SHOW GRANTS FOR 'johnDoe';
+------------------------------------------------------------------+
| Grants for johnDoe                                               |
+------------------------------------------------------------------+
| GRANT USAGE ON *.* TO `johnDoe`                                  |
| GRANT ALL PRIVILEGES ON `db1`.* TO `johnDoe`                     |
+------------------------------------------------------------------+

now reload the data and the operation should be permitted.

mysql -h [host] -u [user] -p[pass] [db_name] < [mysql_dump_name].sql

Answer 7

Full Solution

All the above solutions are fine. And here I'm gonna combine all the solutions so that it should work for all the situations.

1. Fixed DEFINER

For Linux and Mac

sed -i old 's/\DEFINER\=`[^`]*`@`[^`]*`//g' file.sql

For Windows
download atom or notepad++, open your dump sql file with atom or notepad++, press Ctrl+F
search the word DEFINER, and remove the line DEFINER=admin@% (or may be little different for you) from everywhere and save the file.
As for example
before removing that line: CREATE DEFINER=admin@% PROCEDURE MyProcedure
After removing that line: CREATE PROCEDURE MyProcedure

1. Remove the 3 lines Remove all these 3 lines from the dump file. You can use sed command or open the file in Atom editor and search for each line and then remove the line.
   Example: Open Dump2020.sql in Atom, Press ctrl+F, search SET @@SESSION.SQL_LOG_BIN= 0, remove that line.

SET @@SESSION.SQL_LOG_BIN= 0;
SET @@GLOBAL.GTID_PURGED=/*!80000 '+'*/ '';
SET @@SESSION.SQL_LOG_BIN = @MYSQLDUMP_TEMP_LOG_BIN;

2. There an issue with your generated file You might face some issue if your generated dump.sql file is not proper. But here, I'm not gonna explain how to generate a dump file. But you can ask me (_)

Answer 8

Issue

Below statement or line your Dump file creating issue

DEFINER=username@`%

Simple Solution

The solution that you can workaround is to remove all the entries from SQL dump file and import data from the GCP console.

 cat DUMP_FILE_NAME.sql |  sed -e 's/DEFINER=`<username>`@`%`//g' > NEW-CLEANED-DUMP.sql

above command will help to remove all those lines from the dump file and create the new fresh dump file without Definer.

Try importing new file(NEW-CLEANED-DUMP.sql).

If you are on AWS RDS

You might see face issue, if your dump file is larger you can check the first 20 lines using

head -30 filename

once you can see output look for line and line number

SET @@SESSION.SQL_LOG_BIN= 0;
SET @@GLOBAL.GTID_PURGED=/*!80000 '+'*/ '';
SET @@SESSION.SQL_LOG_BIN = @MYSQLDUMP_TEMP_LOG_BIN; 

we will remove these lines by line numbers for example 17,18,24 line number

sed -e '24d;17d;18d' file-name.sql > removed-line-file-name.sql

Answer 9

For importing database file in .sql.gz format, remove definer and import using below command

zcat path_to_db_to_import.sql.gz | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' | mysql -u user -p new_db_name

1. Earlier, export database in .sql.gz format using below command.

   mysqldump -u user -p old_db | gzip -9 > path_to_db_exported.sql.gz;

2. Import that exported database and removing definer using below command,

   zcat path_to_db_exported.sql.gz | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' | mysql -u user -p new_db

Answer 12

If it helps, when I tried to restore a DB dump on my AWS MySQL RDS, I got this error:

ERROR 1227 (42000) at line 18: Access denied; you need (at least one of) the SUPER, 
SYSTEM_VARIABLES_ADMIN or SESSION_VARIABLES_ADMIN privilege(s) for this operation

I didn't have to change the DEFINER or remove/comment out lines. I just did:

GRANT SESSION_VARIABLES_ADMIN ON *.* TO myuser@'myhost';
GRANT SYSTEM_VARIABLES_ADMIN ON *.* TO myuser@'myhost';

And I was able to do the restore.

Answer 13

None of the above solutions worked for me. I had to do the following:

• Use the following flags with mysqldump:

  mysqldump --databases <db1> <db2> --master-data=1 --single-transaction --order- 
  by-primary --foce -r all.sql -h<host> -u<user> -p<password>
  

• Remove the line that looks like:

  CHANGE MASTER TO MASTER_LOG_FILE='binlog.....
  

  • In my file, that was line #22, so I ran: sed -i '22d' all.sql

• Import the data to your RDS:

  mysql -h<host> -u<user> -p<password>
  $ source all.sql
  

Inflatable

Did your dump still contain the three SET lines that all the other solutions say we have to delete? I can't see how these flags will make a difference – Councilman

Answer 14

In my case (trying to execute a SQL file into AWS RDS) the beginning of my SQL statement looked like this:

DROP VIEW IF EXISTS `something_view`;
CREATE ALGORITHM=UNDEFINED DEFINER=`root`@`%` SQL SECURITY DEFINER VIEW `something_view`...

All I had to do to fix it was to remove ALGORITHM=UNDEFINED DEFINER='root'@'%' SQL SECURITY DEFINER part of the above statement.

So the new statement looks like this:

CREATE VIEW 'something_view' ...

Answer 16

* Answer may only be applicable to MacOS *

When trying to import a .sql file into a docker container, I encountered the error message:

Access denied; you need (at least one of) the SUPER privilege(s) for this operation

Then while trying some of the other suggestions, I received the below error on my MacOS (osx)

sed: RE error: illegal byte sequence

Finally, the following command from this resource resolved my "Access Denied" issue.

LC_ALL=C sed -i old 's/\DEFINER\=`[^`]*`@`[^`]*`//g' fileName.sql

So I could import into the docker database with:

docker exec -i dockerContainerName mysql -uuser -ppassword table < importFile.sql

Hope this helps! :)

Answer 20

Now you can grant SET_USER_ID to the user which is running the import on a mysql RDS instance:
GRANT SET_USER_ID ON *.* TO 'import_user'@'%';

then you can run:
mysql -h xxxx.rds.amazonaws.com -u import_user -ppass db < db.sql

SET_USER_ID from mysql doc:

A user with this privilege can specify any account as the DEFINER attribute of a view or stored program
