Note: A schema-less NoSQL database like MongoDB never experiences the 1045 error.

You are not authorized to access the database from localhost, as indicated by this error message. For instance, you may not have sufficient permissions or are using the incorrect account or password.

Main Reasons for MySQL Error 1045 Access Denied

Before identifying solutions to address a problem, it is advisable to thoroughly investigate the root causes of the issue to prevent the system from exhibiting such behavior. Here are the causes of the Error 1045(28000) access denied for user root localhost:

  • Wrong Username & Password:  The most frequent cause of the error is because of the incorrect login credentials. When connecting to the database, users could provide the incorrect username and password. SQL Server is therefore unable to determine whether the account is authentic.
  • Accessing from the Wrong Host: To improve security, MySQL employs host-based access controls for users. Stated differently, MySQL restricts user access to hosts listed in the MySQL user database. Therefore, the error will be displayed upon any attempt to access this user table from distant machines whose hostnames are not defined. Anyway, you can use the update user set host='hostname' where user='username'; command to add a host in the MySQL user table.
  •  The user doesn’t exist: When a user tries to access a database that doesn’t exist/registered on the MySQL server, they get the error.
  •  Connected Anonymous Users:  This error also appears for website owners when users of MySQL are anonymous. The MySQL server sorts through the rows in the user table when a client tries to connect to the database. The first row that precisely matches the hostname and login is used by the server. Thus, while connecting from localhost, the anonymous user (”@localhost) comes before any other users, such as ‘user’@localhost. Using the delete from user where User = ' '; command would be helpful to remove the anonymous user from MySQL.
  • Insufficient Privileges: If you do not possess the required permissions, you will not be allowed to access the MySQL database.
  • Bash interference: Bash can change special characters in a password. To prevent this, you can, however, enclose the password in single quotations.
  • Lack of SSL: A Secure Sockets Layer (SSL) may be needed to access the database, however, it’s possible that you don’t have a working SSL certificate.

All the above error causes have their best solutions. Stay with us to find out how to fix MySQL error 1045 once you identified it.

4 Verified Solutions to Fix MySQL Error 1045: Access Denied

So far, you have learned about MySQL error 1045 and the reasons it might occur. Let’s review this tutorial’s main part and review four different methods to fix MySQL error 1045.

Solution 1. Check the Login Credentials Correctness

You undoubtedly believe that you are entering the username and password correctly, but you are wrong. This simple solution helps you to fix MySQL error 1045. Make sure the user and password are accurate on many occasions. Sometimes, even though it might seem obvious, using the wrong username and password is the root of the MySQL 1045 Error. Even a region or a major city might have an impact at times. For example, utilizing the password operavps1 is different from using OperaVPS1.

Moreover, confirm that the layout of your keyboard is correct. For example, let’s say your password contains the letter ñ, but your keyboard is set up so that when you write it, another letter appears; and like most, you might be typing the password incorrectly if nothing appears when it is required. Lastly, it is best to copy and paste the values; however, copy them from a clear text editor because sometimes when you copy them from another source, they will include spaces and everything.

Thankfully, you can verify this data by looking through your wp-config.php file. By opening a file manager through the control panel of your host, you can locate this file.

Finding your site’s root directory—typically designated public_html—is the first step in using this method. Next, it ought to contain the wp-config.php file:

Using the Correct Username and Password to Fix MySQL Error

Note 1: You can also access your website using SFTP.

Next, verify that the values for DB_USER and DB_PASSWORD are accurate by opening the file. “root” is the username. The password you specify during installation is what you’ll use in the interim.

You can use cPanel, and navigate to Database databases > Current Users if you can’t remember the password you made. In this way, you can reset the database user password.

Note 2: The @ sign is used in various computer languages to distinguish between the host and the user, and therefore the password. The issue arises when you insert the at symbol because concatenation will generate an error. After all, the host will be seen as coming after the @ symbol, leading to conflicts. So, you are recommended to take the at symbol out of passwords. Use secure, lengthy passwords, of course, but omit the sign. If not, you may also check if there are any limitations for sending the string encoding by reading the documentation for the driving force you use.

Solution 2. Check User’s Privileges

The lack of privileges for the user “root” is one of the primary causes of the MySQL 1045 Error. So, you’ll need to find out the current state of these privileges first.

First, open your terminal and run the following command to check the user permissions:

ssh username@ipaddress

Once you are logged in, add the command below from the MySQL prompt:

mysql -uroot -p

Then, to grant all privileges, type:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'password';

Using phpMyAdmin to Check the User Privileges

phpMyAdmin can also be used to verify the user privileges. You will need to click on the User Accounts tab after logging into your hosting account in this case.

Using cPanel to Check the User Privileges

In cPanel servers, follow the path below to manage user privileges:

cPanel > Mysql databases > Current databases > Privileged users > Click on the database user.

For further security, this will encrypt your password. Then, to save your new password, click the Go button at the bottom of the screen.

Solution 4. Verify the Correctness of the port MySQL is Listening to

A further expedient fix for the MySQL 1045 Error is to confirm that the server is listening on the appropriate port. However, it’s helpful to confirm that MySQL is running first.

First, run the command below to check the server status:

systemtl status MySQL

systemtl start MySQL
