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

I had the same error for last 2 days. Tried bunch of things. Nothing worked.
But this did work:
Create another user. Grant it everything.
mysqldump -u new_user db_name > db_name.sql //no error

Answer 2

I just ran into this after a fresh install of MySQL 5.6.16.

Oddly, it works without the password specified or flagged:

mysqldump -u root myschema mytable > dump.sql

Answer 3

I had to remove the single ticks after the password flag:

--password=mypassword

and NOT

--password='mypassword'

Answer 4

Access dined problem solved when I run command prompt in Administrator mode.

Go to Start-> All Programs -> Accessories right click on Command Prompt clickc on Run as.. Select The Following User select administrator username from select option enter password if any click OK button.

Example 1: For entire database backup in mysql using command prompt.

In Windows 7 and 8

C:\Program Files <x86>>\MySQL\MySQL Server 5.5\bin>mysqldump test -u root -p >testDB.sql
Enter Password: *********

In Windows xp

C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqldump test -u root -p >testDB.sql
Enter Password: *********

It asks password for credentials enter password and click on Enter button.

Example 2: For specific table backup / dump in mysql using command prompt.

In Windows 7 and 8

C:\Program Files <x86>>\MySQL\MySQL Server 5.5\bin>mysqldump test -u root -p images>testDB_Images.sql
Enter Password: *********

In Windows xp

C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqldump test -u root -p images>testDB_Images.sql
Enter Password: *********

Dumpt file will be created under folder

In windows xp

C:\Program Files\MySQL\MySQL Server 5.5\bin

In windows 7 and 8

C:\Program Files (x86)\MySQL\MySQL Server 5.5\bin

Note: Check MySQL installation folder in Windows 7, 8 while run in command prompt. If MySQLWorkbench is 32 bit version it is installed in Program Files (x86) folder other wise Program Files folder.

Answer 5

mysqldump -u (user) -p(passwd) -h (host_or_IP) database_to_backup > backup_file.sql

example:

mysqldump -u god -pheaven -h 10.0.10.10 accounting > accounting_20141209.sql

this would create sql backup file for the accounting database on server 10.0.10.10. Sometimes your error is seen when localhost is not in config. Designating ip of server may help.

Answer 6

Put The GRANT privileges:

GRANT ALL PRIVILEGES ON mydb.* TO 'username'@'%' IDENTIFIED BY 'password';
