I developed my website, but many pages that access the database throw the error ‘SQLSTATE 42000 1044 access denied for user’. Can you help!

That was a recent support ticket received at our Outsourced Technical Support department where we resolve support queries for web hosts.

Website owners often face this error due to insufficient database privileges, typo errors in username/password, and more.

So, what’s the solution here? Well, the solution varies depending on the reason for this error.

Today, let’s discuss the top 5 reasons for this error and how our Dedicated Support Engineers fix it.

‘SQLSTATE 42000 1044 access denied for user’ – What this means?

Before we move on to the reasons for this error, let’s first get an idea of this error.

Website owners usually face this error when MySQL disallow access to a database.

For instance, the complete error message looks like this:

SQLSTATE[42000] [1044] Access denied for user 'test'@'localhost' to database 'test_database'

This error shows that MySQL denies the user ‘test’@’localhost’ access to the ‘test_database’ database.

‘SQLSTATE 42000 1044 access denied for user’ – Causes and Fixes

In our experience managing servers, let’s see the main causes of this error and how our Dedicated Support Engineers fix it.

1) Incorrect details in website configuration file

This is the most common reason for the error ‘SQLSTATE 42000 1044 access denied for user‘.

Database driven websites like WordPress, Drupal, etc. use the details in the website configuration file to connect to the database and fetch data.

So, typo errors in the database name, database username, password, hostname, database port, etc. can lead to errors.

How we fix?

In such cases, our Hosting Engineers recover the database details, and correct them in the website configuration files.

And, if we can’t recover the password, we reset it and update it in the website configuration file.

Also, we ensure that the new password adheres to the MySQL password policy.

For example, in cPanel servers, we reset the database user password from

cPanel > Databases > MySQL databases > MySQL users > Current users.

2) Database user doesn’t exist

Similarly, this error occurs when the user trying to access the database doesn’t exist on the MySQL server.

Also, this error can sometimes occur when the database user isn’t properly mapped to the database.

How we fix?

In such cases, our Support Engineers check whether the database user exists in the MySQL user table.

If not, we check the user’s requirement and if valid, we create a user with that username.

In addition to that, we assign this user to the corresponding database.

For instance, in cPanel servers, we map the database user to the database from cPanel > Databases > MySQL Databases > MySQL users > Add User to Database.

3) Insufficient database user permissions

Sometimes, database users don’t have the right privileges to access the database.

In such cases, website owners see this error ‘SQLSTATE 42000 1044 access denied for user‘

How we fix?

Here, our Hosting Engineers grant the user, proper privileges over the database to correct this problem.

For example, in cPanel servers, we assign access privileges to a user from here:

cPanel > MySQL databases > Current databases >Privileged users > Click on the database user

How to set database user privileges in cPanel

On plain servers, we assign the user privileges from command line.

For example, we use the below command to grant all privileges to the user, ‘test’@’localhost to the database ‘test_database’.

GRANT ALL PRIVILEGES ON test_database.* TO 'test'@'localhost';

And, in-order for the changes to reflect, and the privileges to be saved, we use the below command.

FLUSH PRIVILEGES;

4) Existence of anonymous users

Website owners face this error when there exist anonymous users like ‘ ‘@localhost or ‘ ‘ @127.0.0.1.

That is, when a client connects to the database, MySQL looks through the rows in the user table in a sorted way.

And, it uses the first row that matches the hostname and username.

So, here the anonymous user precedes all other users when connecting from localhost.

How we fix?

Our Support Engineers check the MySQL user table and remove the anonymous user.

For instance, we use the below command to remove the anonymous user from MySQL user table.

delete from user where User=' ';

5) Missing PDO module

Website developers see this error when trying to access the database using PDO.

PDOException: SQLSTATE[42000] [1044] Access denied for user 'test'@'localhost' to database 'test_database' in lock_may_be_available() (line 164 of /home/test/public_html/includes/lock.inc).

And, this often occurs due to the missing PDO module.

Most web hosts enable PDO module by default, but some web hosts may disable this module.

How we fix?

In such cases, our Hosting Engineers enable the PDO module on the server.

On cPanel servers, we enable it exclusively for the domain via the PHP Selector option.

Conclusion

In short, ‘SQLSTATE 42000 1044 access denied for user’ error can occur due to insufficient user rights, typo in username/password, and more. Today, we’ve discussed the top 5 reasons for this error and how our Dedicated Support Engineers fix it.
