No, you should run mysql -u root -p in bash, not at the MySQL command-line.
If you are in mysql, you can exit by typing exit.

You may need to set up a root account for your MySQL database:

In the terminal type:

mysqladmin -u root password 'root password goes here'

And then to invoke the MySQL client:

mysql -h localhost -u root -p

I was brought here by a different problem.
Whenever I tried to login, i got that message because instead of authenticating correctly I logged in as anonymous user. The solution to my problem was:

To see which user you are, and whose permissions you have:

select user(), current_user();

To delete the pesky anonymous user:

drop user ''@'localhost';

This is something to do with user permissions. Giving proper grants will solve this issue.

Step [1]: Open terminal and run this command

$ mysql -uroot -p

Output [1]:
This should give you mysql prompt shown below

Step [2]:

mysql> CREATE USER 'parsa'@'localhost' IDENTIFIED BY 'your_password';
mysql> grant all privileges on *.* to 'parsa'@'localhost';

Syntax:

mysql> grant all privileges on `database_name`.`table_name` to 'user_name'@'hostname';

Note:

hostname can be IP address, localhost, 127.0.0.1

In database_name/table_name, * means all databases

In hostname, to specify all hosts use ‘%’

Step [3]: Get out of current mysql prompt by either entering quit / exit command or press Ctrl+D.

Step [4]: Login to your new user

$ mysql -uparsa -pyour_password

Step [5]: Create the database

mysql> create database `database_name`;

You might want to try the full login command:

mysql -h host -u root -p

where host would be 127.0.0.1.

Do this just to make sure cooperation exists.

Using mysql -u root -p allows me to do a a lot of database searching, but refuses any database creation due to a path setting.

If you are in a MySQL shell, exit it by typing exit, which will return you to the command prompt.

Now start MySQL by using exactly the following command:

sudo mysql -u root -p

If your username is something other than root, replace ‘root’ in the above command with your username:

sudo mysql -u <your-user-name> -p

It will then ask you the MySQL account/password, and your MySQL won’t show any access privilege issue then on.

First, if you are unfamiliar with the command line, try using phpmyadmin from your webbrowser. This will make sure you actually have a mysql database created and a username.

This is how you connect from the command line (bash):

mysql -h hostname -u username -p database_name

For example:

fabio@crunchbang ~ $ mysql -h 127.0.0.1 -u fabio -p fabiodb

connect mysql with sudo & gives permission for the necessary user using,

sudo mysql -u user;
GRANT ALL PRIVILEGES ON database_name.* TO 'user'@'localhost';

answered Apr 20, 2021 at 5:09

@Nickparsa … you have 2 issues:

1). mysql -uroot -p
should be typed in bash (also known as your terminal) not in MySQL command-line. You fix this error by typing

exit

in your MySQL command-line. Now you are back in your bash/terminal command-line.

2). You have a syntax error:

mysql -uroot -p;

the semicolon in front of -p needs to go. The correct syntax is:

mysql -uroot -p

type the correct syntax in your bash commandline. Enter a password if you have one set up; else just hit the enter button. You should get a response that is similar to this:

Hope this helps!

Most Developers log-in to server(I assume you r having user-name and password for mysql database) then from Bash they switch to mysql> prompt then use the command below(which doesn’t work

mysql -h localhost -u root -p

What needs to be done is use the above command in the bash prompt—> on doing so it will ask for password if given it will take directly to mysql prompt and

then database, table can be created one by one

I faced similar deadlock so sharing the experience

I had the command correct per above answers, what I missed on was on the Workbench, where we mention ‘Limit Connectivity from Host’ for the user, it defaults to «%» — change this to «localhost» and it connects fine thereafter!

I’m using roles to confer least privilege on my database application users. I kept getting ‘ERROR 1044 (42000): Access denied for user…’ until I RTFM and discovered I had to give each user a default role(s) in order their account could be authenticated when they logged in.

#create a role
CREATE ROLE 'rolename';

#give necessary privileges to role
GRANT INSERT, UPDATE, DELETE, SELECT ON database.table TO 'rolename';

#create user
CREATE USER 'username'@'host' IDENTIFIED BY 'password';

#give the user a role(s)
GRANT 'rolename' TO 'username'@'host';

#set the user's default otherwise it's ERROR 1044
SET DEFAULT ROLE 'rolename' FOR 'username'@'host';

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.

[You don’t have to be a MySQL expert to keep your websites online. Our MySQL admins are available round the clock.]

‘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.

MySQL databases option in cPanel

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;

[Struggling with database user permissions and privileges. Our MySQL experts are here for your help.]

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.

PHP Selector in cPanel

[If you suspect missing PHP modules in your server. Our Support Experts can fix it for you within minutes.]

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.

This page will assist you with troubleshooting a MySQL – 1044 “Access Denied” Error Message.

Troubleshooting the MySQL 1044 “Access Denied” Error

When you import a database using phpMyAdmin, generally you are importing a text file with a .sql extension.

Here is a section of code that may be in a .sql database backup. In this example, the database we are trying to import is named Employees.

-- phpMyAdmin SQL Dump -- version 2.11.9.5 -- https://www.phpmyadmin.net -- -- Host: localhost -- Generation Time: Apr 02, 2010 at 08:01 AM -- Server version: 5.0.81 -- PHP Version: 5.2.6   
SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";   
CREATE DATABASE employees;   
-- --------------------------------------------------------   -- -- Table structure for table `employee_list` --   
CREATE TABLE 
IF NOT EXISTS `employee_list` ( `first_name` text NOT NULL, `last_name` text NOT NULL ) 
ENGINE=MyISAM 
DEFAULT CHARSET=latin1;

When using phpMyAdmin to attempt to import such a file, you will receive an error message similar to:

 Error
 
SQL query:
  
 CREATE DATABASE employees;
  
 MySQL said: Documentation
 #1044 - Access denied for user 'training'@'localhost' to database 'employees'

In this scenario, my cPanel username is Training. Because of cPanel’s database naming conventions, all database names must begin with the cPanel username followed by an “_”. I cannot create a database named Employees, however I can create a database named Training_employees.

The reason this import failed is because of the following line in the .sql file:

CREATE DATABASE employees

Again, I cannot create a database named employees, however I can create a database named Training_employees. If I change the line that says: CREATE DATABASE so that it creates: training_employees instead of employees it will again fail with the following message:

 Error
  
 SQL query:
  
 CREATE DATABASE training_employees;
  
 MySQL said: Documentation
 #1044 - Access denied for user 'training'@'localhost' to database 'training_employees'

When using cPanel, databases must be created within the cPanel itself. To fix the issue, you will need to:

Create the: training_employees database within cPanel
Comment out the: CREATE DATABASE command in my .sql file. To do this, simply change: CREATE DATABASE employees; to — CREATE DATABASE employees; You are simply adding dash dash space to the front of the line to comment it out so that it will not be executed.
Log into phpMyAdmin, access the training_employees database, and then import as normal.

To login into MySQL as root user, you can use:

mysql -u root -p

and then enter your MySQL password.

To login as another user, you will have to create that user first and grant him privileges.

Create the user using — change newuser to the username you want and password to your password of choice.

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

Sadly, at this point newuser has no permissions to do anything with the databases.
Therefore the first stage is to grant the user the privileges to do ‘things’.
To grant all privileges (select, create, delete, update, drop, etc) on all databases and tables, run:

GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost';

To grant a specific privilege on a particular database and table, just run:

GRANT [type of privilege] ON [database name].[table name] TO '[username]'@'localhost';

If you ever need to deny or revoke a certain privilege, just run:

REVOKE [type of permission] ON [database name].[table name] FROM '[username]'@'localhost';

I found two possible solutions, either:

your user is missing the LOCK privilege, so you should ask your database administrator to grant it to you
run the same mysqldump command, simply adding the --single-transaction flag, eg. mysqldump --single-transaction -u user -p ...

answered May 29, 2015 at 8:32

A quick workaround is to pass the –-single-transaction option to mysqldump:

$ mysqldump --single-transaction -u user -p DBNAME > backup.sql

Just for sharing, the below article have a good information about the same issue.

IF yours password contains special characters then; the error

mysqldump: Got error: 1045: «Access denied for user ‘root’@’localhost’ (using password: YES)» when trying to connect might occur.

Solution is simple; instead of giving the password in quotes at the time of issuing the command (for example mysql or mysqldump) just use -p. and it would ask to enter the password in terminal.

mysqldump -h localhost -u root --password='password' --add-drop-database --add-drop-table --add-drop-trigger --dump-date --single-transaction --routines --events db > /path/db_name.sql

FYI: I know this is for errors 1045 (and not 1044 using locking tables), but might help.
