Resolving the mysqldump: Got error: 1045: Access denied for user Error on Debian Web Servers


In the world of Debian-based servers, many system administrators may encounter the dreaded “mysqldump: Got error: 1045: Access denied for user” error while executing a MySQL dump command. This situation happens when the user trying to execute the mysqldump does not have the required privileges or when the credentials are incorrect.

While you often can’t directly use the ‘useradd’ command to solve this problem, you can create a new user with appropriate permissions in MySQL, which should solve this error. Let’s take a step-by-step look at the process.

Solution: Create a New MySQL User with Appropriate Permissions

First, log in to your MySQL server as the root user. If your MySQL server is installed on the local machine, you can use the following command from your terminal:

mysql -u root -p

It will prompt for your MySQL root user’s password. After entering the password, you should be logged into your MySQL server.

Now, let’s create a new user. Imagine we will call our new user ‘newuser’ and set the password as ‘newuserpassword’.

CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'newuserpassword';

The next step is to grant this user the necessary privileges. To execute mysqldump, the user should at least have SELECT, SHOW VIEW, TRIGGER, LOCK TABLES privileges. We can give these privileges by running the following command:


Finally, flush the privileges to ensure that the changes take effect immediately:


Now, exit the MySQL interface by typing ‘exit’ and hitting enter. You should now be able to execute the mysqldump command with the new user ‘newuser’ and password ‘newuserpassword’.

mysqldump -u newuser -p newuserpassword DB_NAME > backup.sql

And voila! The mysqldump command should now execute successfully, creating a dump of the database named ‘DB_NAME’ into the ‘backup.sql’ file.


To sum it all up, the infamous “mysqldump: Got error: 1045: Access denied for user” error is caused by insufficient privileges or incorrect user credentials in MySQL. By creating a new MySQL user and granting them the required privileges, you should be able to resolve this error swiftly and carry on with your work.

Remember, as a system administrator, it’s important to understand not just how to fix errors, but why they happen in the first place. Always stay curious, and keep learning!
