mysqldump Error 1045 Access denied despite correct

Question

This is a tricky one, I have the following output:

mysqldump: Got error: 1045: Access denied for user 'root'@'localhost' (using password: YES) when trying to connect

When attempting to export my database with mysqldump on Windows XP. The username is root, the password is correct and contains only alphanumeric characters. I have tried different cases, with/without quotes, specifying using -u and -p, specifying using --user= and --password= and other methods of specifying user/passwords etc, specifying the host (it's all local) and even specifying the database using --databases instead of just blank. The error is always the same when using a password and always the same except the "NO" message when without. I have tried many fixes found through searches with no success. One fix suggested inspecting mysql.conf, but the Windows build doesn't seem to have one. The credentials (and indeed commandline parameters) work perfectly with mysql.exe - this problem only seems to be affecting mysqldump.exe.

Many thanks for your help.

Answer 1

For MAMP PRO users (or anyone who's mysql is in a weird location) be prepared to specify the mysql full path from the boonies and also specify full path to your user local folder where you want to dump the file or you'll get the "permission denied error"..

Following worked for me after 3 hours of research:

/Applications/MAMP/Library/bin/mysqldump  -u root -proot YOUR_DB > /Users/YOUR_USER/yourdump2.sql

Answer 2

Don't enter the password with command. Just enter,

mysqldump -u (username) -p (db_name) > (backup_file).sql

Then you will get a prompt to enter password.

Answer 3

Try to remove the space when using the -p-option. This works for my OSX and Linux mysqldump:

mysqldump -u user -ppassword ...

Answer 4

I discovered a running apache process acessing the MYSQL causing this error. So I suggest to ensure that all processes which might interact with the DB are shutdown beforehand.

Answer 5

Mysql replies with Access Denied with correct credentials when the mysql account has REQUIRE SSL on

The ssl_ca file (at a minimum) had to be provided in the connection paramiters.

Additional ssl parameters might be required and are documented here: http://dev.mysql.com/doc/refman/5.7/en/secure-connection-options.html

Answer 6

This worked for me

mysqldump -u root -p mydbscheme > mydbscheme_dump.sql

after issuing the command it asks for a password:

Enter password:

entering the password will make the dump file.
