Ошибка 1698 mysql

Are you getting the following error when trying to login to the MySQL root on an Ubuntu system or other Linux distribution? We’ll show you how to clear it up in a matter of seconds.

ERROR 1698 (28000): Access denied for user 'root'@'localhost'

Explanation: This error is caused by the auth_socket plugin. The simplest solution is to just disable the plugin which we will show you how to do below.

Follow the corresponding section below, depending on whether you’re running MySQL Server or MariaDB Server, as both implementations require a different solution to fix the root login problem.

MySQL Server

In this section, we will fix the ERROR 1698 for a MySQL Server installation:

Step 1. Log in to MySQL as root (using sudo will bypass MySQL’s password prompt):

$ sudo mysql -u root

Step 2. Change to the mysql database and set the plugin to mysql_native_password for the root user:

mysql> USE mysql;
mysql> UPDATE user SET plugin='mysql_native_password' WHERE User='root';
mysql> FLUSH PRIVILEGES;

Step 3. You have to change the root password for this to work. Even just specifying the current password is fine too, but this command must be executed:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password_here';
mysql> exit;

Step 4. Lastly, restart MySQL for the changes to take effect:

$ sudo systemctl restart mysql

Step 5. You can now log in to MySQL root as normal, and will no longer encounter the error:

$ mysql -u root -p

MariaDB Server

In this section, we will fix the ERROR 1698 for a MariaDB Server installation:

Step 1. The solution for MariaDB is different. Users need to run through initial setup by executing:

$ sudo mysql_secure_installation

Step 2. Press enter when prompted for root password:

Enter current password for root (enter for none):

Step 3. Answer N when asked to enable unix_socket authentication:

Switch to unix_socket authentication [Y/n] n

Step 4. Answer Y when asked if you’d like to change the root password, then supply a new password:

Change the root password? [Y/n] y
New password: 
Re-enter new password:

Step 5. Go through the next few questions, eventually ending by answering Y to reload table privileges:

Reload privilege tables now? [Y/n] y

Step 6. You can now log in to MariaDB root as normal, and will no longer encounter the error:

$ mysql -u root -p

Did this work for you? Let us know in the comments below! Include your system information for help with troubleshooting.

With our easy steps, you can easily solve error 1698 (28000) Access denied for the user.

This error is very common when you try to log in to your MySQL for the first time.

Personally, I too faced this issue multiple times, maybe because we were not following the right way to install MySQL, or we forgot to set a password, or else we didn’t get the options to set a password.

Similarly, there may be many other reasons for the above error, but the solution to this error is pretty simple and easy. In this article, you will find a way to resolve 1698 (28000) Access denied for user ‘root’@’localhost’.

There are two ways to resolve this error.

First, you will see a simple and less time-consuming method. If the first method didn’t work in your case, then go to the second one.

Method 1: The Easiest Way to Fix Error 1698 (28000): Access Denied for User

One of the easiest ways to resolve this error is to invoke “mysql_secure_installation”, which will ask you to set a password for your MySQL root user.

$ sudo mysql_secure_installation 

You need to enter a new password and, for confirmation, re-type that password.

If the password is less than 25 characters, you will be prompted to confirm whether you want to continue or not. If you don’t want to set password characters more than 25, simply type “n”.

In my case, it didn’t work and threw me an error on-screen:

“Failed! Error: SET PASSWORD has no significance for user ‘root’@’localhost’ as the authentication method used doesn’t store authentication data in the MySQL server.

Please consider using ALTER USER instead if you want to change authentication parameters.”

If the same thing happens with you too, then close the terminal and follow the second set of steps, which worked in my case to solve error 1698 (28000) Access denied for user.

Method 2: Fix Error 1698 (28000): Access Denied for User using Alter

When you install MySQL for the first time, there is a chance you will not find the option to set a password because of the new method of authenticating users.

If it is like that, then you need to login to MySQL as a root user.

Most of the time, users may try to log in to MySQL as “mysql -u user” or “mysql -u root”, but it won’t work because “user@localhost” has not yet been created on your system, and root cannot be accessed without sudo privileges.

And when you try to log in as the root user with “mysql -u root@localhost”, you will get the below error.

Check the Authorization Mechanism

To resolve this, you must log into MySQL as a sudo on the new installation because the account that is linked with MySQL is the “root” account, not the “user” account.

Run the below command in your terminal:

$ sudo mysql -u root

Once you are logged in, you will find the MySQL console looking like the below-shown image.

Now you can access your MySQL account with the above command, but there is a small problem with this: you cannot log in to MySQL without sudo privileges.

To fix that, you can create a new user and grant the necessary privileges, or else change the password authentication mechanism of the root account.

There are different types of password mechanisms supported by MySQL by default you will find “auth_socket” for your root account to make it robust you can choose conventional “mysql_native_password” or the latest “caching_sha2_password“ on later version 8.0.0

If you want to learn more about authentication plugins, then do check out MySQL authentication documentation.

Before moving to the next step, you should check what password mechanism or plugin is attached to your root account.

To find out, you can run the following queries on the MySQL console:

mysql> SELECT User, plugin from mysql.user ;

The behavior of the above command is shown below:

Set a password on the root account

Now you can set or update your password by following the below snippet. Make sure to replace [ENTER-NEW-PASSWORD] with your password and, prior to that, select the MySQL database.

mysql> use mysql;
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH 'caching_sha2_password' BY '[ENTER-NEW-PASSWORD]';

Output:

I’m using “caching_sha2_password”.

If you want to use “mysql_native_password” on > MySQL 5.7 version, type the below queries on your MySQL console.

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH 'mysql_native_password' BY '[ENTER-NEW-PASSWORD]';

Once the changes have been implemented, restart the MySQL service.

$ sudo systemctl restart mysql.service

And once the service is restarted, type the below code in your terminal and enter the password which you have set above.

$ mysql -u root -p

Output:

Wrapping Up

That’s all to resolve error 1698 (28000) Access denied for user on MySQL.

I’m sure after following the above steps you will be able to resolve the issue, but if you are still having any issues, then do let me know in the comment section.

The error 1698 (28000): access denied for user ‘root’@’localhost’ is a common error that occurs when you do not have permission to access the database. This article covers all the details of how this error arises and what you can do to resolve it. Let’s begin!

Why Does the Error 1698: Mysql Error Message Occurs?

The error 1698 (28000): access denied for user ‘root’@’localhost’ occurs when the root user tries to perform an action requiring higher privileges than those granted. This happens when the root user’s password is incorrect or has been restricted from accessing certain databases or tables.

Additionally, this error will occur if the root user has been removed from the list of authorized users. It can also occur if there is a conflict between the user’s permissions and the privileges required by the action being performed.

• Missing grant privileges.
• Firewall or Network issues.
• Incorrect MySQL configuration.
• Syntax errors.

– Incorrect Credentials

The most common reason for this error is an incorrect username or password for the ‘root’ user. Ensure that you are using the correct username and password to log in to the MySQL server.

– Insufficient Privileges

If you have recently created a new user, it may not have sufficient privileges to access the MySQL server. Ensure that you have granted the necessary permissions to the user to access the server.

– Missing Grant Privileges

Sometimes, the user may have the necessary privileges to access the server, but the grant privileges are missing. Grant privileges are the ones that allow a user to perform specific operations on a specific database. Ensure that you have granted the necessary grant privileges to the user.

– Firewall or Network Issues

The server may not be reachable due to network or firewall issues. Ensure your network and firewall settings are correctly configured to allow MySQL server connections.

– Incorrect MySQL Configuration

Sometimes, the MySQL server configuration may be incorrect, which can cause the ‘Access Denied’ error. Check the configuration files to ensure that the server is correctly configured.

– Syntax Errors

Syntax errors are another reason why this error occurs. Sometimes, coders accidentally make a typo mistake or use the wrong operands and functions with the wrong brackets.

Such issues cause error messages to arise, such as:

• Error 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: yes).
• Access denied for user ‘root’@’localhost’ (using password: no).
• Error 1045 mysql 28000: access denied for user’ root’@’localhost centos.
• Error 1045 (28000): Access denied for user cacti localhost’ (using password: yes).

How To Resolve the Error 1698: Mysql Error Message?

To solve error 1698 (28000): Access denied for user ‘root’@’localhost’ error, you can grant administrative privileges to the user or create a new user with administrative access. Create a new user with administrative access by running “CREATE USER ‘new_user’@’localhost’ IDENTIFIED BY ‘password’;” and grant them administrative access.

– Reset the Root Password

If you cannot log in to the MySQL or MariaDB database using the root account, you can reset the root password. To do this, stop the MySQL/MariaDB server and restart it with the –skip-grant-tables option. This will let you log in to the database server without a password. Once you are logged in, you can reset the root password using the following command:

UPDATE mysql.user SET authentication_string = PASSWORD(‘new_password’) WHERE User = ‘root’ AND Host = ‘localhost’;

After resetting the password, restart the MySQL/MariaDB server without the –skip-grant-tables option.

– Grant Privileges to the Root User

When the root user doesn’t have the necessary privileges to access the database server, you can grant them using the given command:

GRANT ALL PRIVILEGES ON *.* TO ‘root’@’localhost’ IDENTIFIED BY ‘password’ WITH GRANT OPTION;

Replace ‘password’ with the root user’s password.

– Check the MySQL/MariaDB Configuration

To troubleshoot this error, you should check the MySQL/MariaDB configuration settings to ensure that the ‘root’ user has permission to access the database. Here are some steps you can take:

1. Check the authentication method: MySQL/MariaDB supports several authentication methods, including the traditional password-based authentication method and the more secure plugin-based authentication method. Check your MySQL/MariaDB configuration file to ensure the authentication method is correctly set up and the ‘root’ user has a valid password or authentication plugin.
2. Check the user permissions: Make sure that the ‘root’ user has the permissions to access the database. You can verify this by running the below command:

SELECT user, host, plugin FROM mysql.user WHERE user = ‘root’;

This will show you the authentication plugin being used by the ‘root’ user and the hostnames from which the ‘root’ user can connect to the database.

1. Check the database permissions: Verify that the ‘root’ user has the permissions to access the specified database you’re trying to connect to. You can do this by running the following command:

SHOW GRANTS FOR ‘root’@’localhost’;

This will show you the privileges assigned to the ‘root’ user on the ‘localhost’ host.

1. Restart the MySQL/MariaDB server: If all else fails, try restarting the MySQL/MariaDB server. Sometimes, configuration changes do not take effect until the server is restarted.

– Check the Firewall

If you are connecting to the MySQL/MariaDB server from a remote machine, make sure that the server’s firewall is not blocking the connection. To resolve this error, you can follow these steps:

1. Check your Firewall settings: Ensure your firewall is not blocking the MySQL port (the default port number is 3306). You can check this by opening your Firewall settings and verifying that port 3306 is open.
2. Check MySQL privileges: You can check the privileges of the user ‘root’@’localhost’ by logging in as another user with administrative permissions and running the following command:

SHOW GRANTS FOR ‘root’@’localhost’;

This will display a list of privileges granted to the ‘root’ user. If the user does not have enough privileges, you can grant them by running the following command:

GRANT ALL PRIVILEGES ON *.* TO ‘root’@’localhost’ WITH GRANT OPTION;

1. Restart MySQL service: After making any changes to the MySQL privileges, you should restart the MySQL service to ensure that the changes take effect.

Sudo systemctl restart mysql

1. Test MySQL access: After completing the above steps, you can test whether the ‘root’ user has access to MySQL by logging in with the following command:

If you can log in without any errors, it means that the issue has been resolved.

– Use a Different User Account

Try logging in with a separate user account that has the privileges to access the database server. You can make a new account by using the following command:

– Grant MySQL Access

MySQL Access refers to the ability to interact with a MySQL database using various means, such as through the command line, graphical user interfaces (GUIs), or application programming interfaces (APIs). Granting access will resolve your error message issue.

MySQL Access generally allows users to perform various operations on a MySQL database, such as creating and modifying tables, inserting and updating data, querying data, and managing users and permissions. MySQL Access can be granted to different users with different levels of privileges, depending on their roles and responsibilities.

MySQL Access can be performed using various tools, such as the MySQL command line client, phpMyAdmin, MySQL Workbench, and many other third-party applications and libraries.

– Correct Typo Mistake

If the user makes a typo or a syntax mistake, they can face this error message. Therefore, it is important to find all the syntax and typo mistakes to correct them. You can also get rid of other error messages, such as:

• Error 1045 (28000): Access denied for user ‘zabbix’@’localhost’ (using password: yes)
• db.utils.operationalerror: (1698, denied
• Error 1045 (28000): Access denied for user nextcloud localhost’ (using password: yes)
• Mysql root error 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: yes)

Conclusion
