'ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

I have been following a manual to install a software suite on Ubuntu. I have no knowledge of MySQL at all. I have done the following installations on my Ubuntu.

sudo apt-get update
sudo apt-get install mysql-server-5.5
sudo apt-get install mysql-client-5.5
sudo apt-get install mysql-common
sudo apt-get install glade
sudo apt-get install ntp

Then I do

cd ~/Desktop/iPDC-v1.3.1/DBServer-1.1
mysql -uroot -proot <"Db.sql"

I ended up with the following error message.

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

How may I fix it and continue?

Solution 1:^[1]

I was able to solve this problem by executing this statement

sudo dpkg-reconfigure mysql-server-5.5

Which will change the root password.

Solution 2:^[2]

You have to reset the password! Steps for Mac OS X (tested and working) and Ubuntu:

Stop MySQL using

sudo service mysql stop

sudo /usr/local/mysql/support-files/mysql.server stop

Start it in safe mode:

sudo mysqld_safe --skip-grant-tables --skip-networking

(the above line is the whole command)

This will be an ongoing command until the process is finished, so open another shell/terminal window, log in without a password:

mysql -u root

mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';

As per @IberoMedia's comment, for newer versions of MySQL, the field is called authentication_string:

mysql> UPDATE mysql.user SET authentication_string =PASSWORD('password') WHERE User='root';

Start MySQL using:

sudo service mysql start

sudo /usr/local/mysql/support-files/mysql.server start

Your new password is 'password'.

Note: for version of MySQL > 5.7 try this:

update mysql.user set authentication_string='password' where user='root';

Solution 3:^[3]

I was recently faced with the same problem, but in my case, I remember my password quite alright, but it kept on giving me the same error. I tried so many solutions, but still none helped. Then I tried this:

mysql -u root -p

After which it asks you for a password like this

Enter password:

And then I typed in the password I used. That's all.

Solution 4:^[4]

It happens when your password is missing.

Steps to change the password when you have forgotten it:

Stop MySQL Server (on Linux):
```
sudo systemctl stop mysql
```
Start the database without loading the grant tables or enabling networking:
```
sudo mysqld_safe --skip-grant-tables --skip-networking &
```
The ampersand at the end of this command will make this process run in the background, so you can continue to use your terminal and run mysql -u root (as root). It will not ask for a password.

If you get error like as below:
```
2018-02-12T08:57:39.826071Z mysqld_safe Directory '/var/run/mysqld' for UNIX
socket file don't exists.
mysql -u root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/var/run/mysqld/mysqld.sock' (2)
[1]+  Exit 1
```
Make MySQL service directory.
```
sudo mkdir /var/run/mysqld
```
Give MySQL user permission to write to the service directory.
```
sudo chown mysql: /var/run/mysqld
```
Run the same command in step 2 to run MySQL in background.

Run mysql -u root. You will get the MySQL console without entering a password.

Run these commands

FLUSH PRIVILEGES;

For MySQL 5.7.6 and newer

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';

For MySQL 5.7.5 and older

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('new_password');

If the ALTER USER command doesn't work use:

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

Now exit

To stop the instance started manually:

sudo kill `cat /var/run/mysqld/mysqld.pid`

Restart MySQL
```
sudo systemctl start mysql
```

Solution 5:^[5]

At the initial start up of the server the following happens, given that the data directory of the server is empty:

The server is initialized.
SSL certificate and key files are generated in the data directory.
The validate_password plugin is installed and enabled.
The superuser account 'root'@'localhost' is created. The password for the superuser is set and stored in the error log file.

To reveal it, use the following command:

shell> sudo grep 'temporary password' /var/log/mysqld.log

Change the root password as soon as possible by logging in with the generated temporary password and set a custom password for the superuser account:

shell> mysql -u root -p

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass5!';

Solution 6:^[6]

If the problem still exists, try to force changing the password:

/etc/init.d/mysql stop

mysqld_safe --skip-grant-tables &

mysql -u root

Set up a new MySQL root user password:

use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;
quit;

Stop the MySQL server:

/etc/init.d/mysql stop

Start the MySQL server and test it:

mysql -u root -p

Solution 7:^[7]

If none of the other answers work for you, and you received this error:

mysqld_safe Logging to '/var/log/mysql/error.log'.
mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists.
[1]+  Exit 1                  sudo mysqld_safe --skip-grant-tables

Follow the below commands step by step until you reset your password:

# Stop your server first
sudo service mysql stop

# Make the MySQL service directory.
sudo mkdir /var/run/mysqld

# Give MySQL permission to work with the created directory
sudo chown mysql: /var/run/mysqld

# Start MySQL, without permission and network checking
sudo mysqld_safe --skip-grant-tables --skip-networking &

# Log in to your server without any password.
mysql -u root mysql


# Update the password for the root user:
UPDATE mysql.user SET authentication_string=PASSWORD('YourNewPasswordBuddy'), plugin='mysql_native_password' WHERE User='root' AND Host='localhost';

# If you omit (AND Host='localhost') section, it updates
# the root password regardless of its host

FLUSH PRIVILEGES;
EXIT;

# Kill the mysqld_safe process
sudo service mysql restart

# Now you can use your new password to log in to your server
mysql -u root -p

# Take note for remote access. You should create a remote
# user and then grant all privileges to that remote user

Solution 8:^[8]

I came across this very annoying problem and found many answers that did not work. The best solution I came across was to completely uninstall MySQL and reinstall it. On reinstall you set a root password and this fixed the problem.

sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-5.5 mysql-client-core-5.5
sudo rm -rf /etc/mysql /var/lib/mysql
sudo apt-get autoremove
sudo apt-get autoclean

I found this code elsewhere, so I don't take any credit for it. But it works. To install MySQL after uninstalling it, I think DigitalOcean has a good tutorial on it. Checkout my gist for this.

How to install MySQL on Ubuntu (which works)

Solution 9:^[9]

I am using Ubuntu 16.04 (Xenial Xerus) and installed MySQL 5.7.

I had the same issue

Login denied for root user.

I tried the below steps:

dpkg --get-selections | grep mysql (to get the version of MySQL).
dpkg-reconfigure mysql-server-5.7
mysql -u root -p

Without -p that doesn't prompt you to ask password. Once you are in, you can create a user with a password by following steps:

CREATE USER 'your_new_username'@'your-hostname' IDENTIFIED BY 'your-password';

GRANT ALL PRIVILEGES ON *.* to 'your_new_username'@'your-hostname' WITH GRANT OPTION;

Exit from the root and log in from the <name> you gave above.

mysql -u <your_new_username> -p

For some reason still just typing MySQL does not work. At all. I suggest to make it a habit to use mysql -u <name> -p.

Solution 10:^[10]

In the terminal, just enter:

mysql -u root -p

Then it will ask the password from you.

Solution 11:^[11]

I installed MySQL as root user ($SUDO) and got this same issue

Here is how I fixed it:

sudo cat /etc/mysql/debian.cnf

This will show details as:

# Automatically generated for Debian scripts. DO NOT TOUCH! [client] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock [mysql_upgrade] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock

Above we can see the password. But we are just going to use(GUx0RblkD3sPhHL5) that in the prompt.
`mysql -u debian-sys-maint -p

Enter password: `

Now provide the password (GUx0RblkD3sPhHL5).
Now exit from MySQL and log in again as:

`mysql -u root -p

Enter password: `

Now provide the new password. That's all. We have a new password for further uses.

It worked for me.

Solution 12:^[12]

Please read the official documentation: MySQL: How to Reset the Root Password

If you have access to a terminal:

MySQL 5.7.6 and later:

mysql

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

MySQL 5.7.5 and earlier:

mysql

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');

Solution 13:^[13]

For those for whom the current answers didn't work can try this (tested on macOS):

mysql -h localhost -u root -p --protocol=TCP

After this, a password will be asked from you and you should use your OS user password. Then when you get into MySQL you can run:

select Host, User from mysql.user;

And you should see:

MySQL [(none)]> select Host, User from mysql.user;
+-----------+------------------+
| Host      | User             |
+-----------+------------------+
| localhost | mysql.infoschema |
| localhost | mysql.session    |
| localhost | mysql.sys        |
| localhost | root             |
+-----------+------------------+

And from here you can change the configurations and edit the password or modify the grants.

Solution 14:^[14]

I am using mysql-5.7.12-osx10.11-x86_64.dmg on Mac OS X.

The installation process automatically sets up a temporary password for the root user. You should save the password. The password can not be recovered.

Follow the instructions:

Go to cd /usr/local/mysql/bin/
Enter the temporary password (which would look something like, "tsO07JF1=>3")
You should get the mysql> prompt.
Run, SET PASSWORD FOR 'root'@'localhost' = PASSWORD('{YOUR_PASSWORD}'); If you wish to set your password: "root" then the command would be, SET PASSWORD FOR 'root'@'localhost' = PASSWORD('root');
Run ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
Run exit
Run ./mysql -u root -p
Type your password. In my case I would type, "root" (without quote)
That's all.

For convenience, you should add "/usr/local/mysql/bin" to your PATH environment variable.

Now from anywhere you can type ./mysql -u root -p and then type the password and you will get the mysql> prompt.

Solution 15:^[15]

The answer may sound silly, but after wasting hours of time, this is how I got it to work:

mysql -u root -p

I got the error message

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Even though I was typing the correct password (the temporary password you get when you first install MySQL).

I got it right when I typed in the password when the password prompt was blinking.

Solution 16:^[16]

If you have MySQL as part of a Docker image (say on port 6606) and an Ubuntu install (on port 3306) specifying the port is not enough:

mysql -u root -p -P 6606

will throw:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

as it's trying to connect to localhost by default, specifying your local IP address fixes the issue:

mysql -u root -p -P 6606 -h 127.0.0.1

Solution 17:^[17]

If the problem still exists, try to force changing the password.

Stop MySQL Server (on Linux):

/etc/init.d/mysql stop

Stop MySQL Server (on Mac OS X):

mysql.server stop

Start the mysqld_safe daemon with --skip-grant-tables:

mysqld_safe --skip-grant-tables &
mysql -u root

Set up a new MySQL root user password:

use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;
quit;

Stop MySQL Server (on Linux):

/etc/init.d/mysql stop

Stop MySQL Server (on Mac OS X):

mysql.server stop

Start the MySQL server service and test to log in by root:

mysql -u root -p

Solution 18:^[18]

Year 2021.

Answer for Ubuntu 20.04 (Focal Fossa) (maybe other distributions as well).

After days of wandering around... and having none of those answers working for me, I did this and it worked!

Always in a Bash shell:

sudo systemctl disable mysql

In order to stop the daemon from starting on boot.

sudo apt purge mysql-server

and

sudo apt purge mysql-community-server*

There, it warns you you'll erase configuration files... so it's working! Because those are the ones making trouble!

sudo autoremove

To delete all the left behind packages.

Then (maybe it's optional, but I did it) reboot. Also, I downloaded mysql-server-8.0 from the official MySQL webpage:

sudo apt install mysql-server

A signal that it's working is that when you enter the command above, the system asks you to enter the root password.

Finally:

mysql -u root -p

And the password you entered before.

Solution 19:^[19]

By default, the password will be null, so you have to change the password by doing the below steps.

Connect to MySQL

root# mysql

Use mysql

mysql> update user set password=PASSWORD('root') where User='root';

Finally, reload the privileges:

mysql> flush privileges;
mysql> quit

Solution 20:^[20]

Just one line and it solved my issue.

sudo dpkg-reconfigure mysql-server-5.5

Solution 21:^[21]

In Ubuntu 16.04 (Xenial Xerus) and MySQL version 5.7.13, I was able to resolve the problem with the steps below:

Follow the instructions from section B.5.3.2.2 Resetting the Root Password: Unix and Unix-Like Systems MySQL 5.7 reference manual

When I tried #sudo mysqld_safe --init-file=/home/me/mysql-init & it failed. The error was in /var/log/mysql/error.log:

2016-08-10T11:41:20.421946Z 0 [Note] Execution of init_file '/home/me/mysql/mysql-init' started.
2016-08-10T11:41:20.422070Z 0 [ERROR] /usr/sbin/mysqld: File '/home/me/mysql/mysql-init' not found (Errcode: 13 - Permission denied)
2016-08-10T11:41:20.422096Z 0 [ERROR] Aborting

The file permission of mysql-init was not the problem. We need to edit AppArmor permissions.

Edit by sudo vi /etc/apparmor.d/usr.sbin.mysqld

 ....
   /var/log/mysql/ r,
   /var/log/mysql/** rw,


 # Allow user init file
   /home/pranab/mysql/* r,

   # Site-specific additions and overrides. See local/README for details.
   #include <local/usr.sbin.mysqld>
 }

Do sudo /etc/init.d/apparmor reload
Start mysqld_safe again. Try step 2 above. Check file /var/log/mysql/error.log. Make sure there is no error and the mysqld is successfully started.
Run mysql -u root -p

Enter password:

Enter the password that you specified in mysql-init. You should be able to log in as root now.
Shutdown mysqld_safe by sudo mysqladmin -u root -p shutdown
Start mysqld the normal way by sudo systemctl start mysql

Solution 22:^[22]

While the top answer (with mysqladmin) worked on macOS v10.15 (Catalina), it did not work on Ubuntu. Then I tried many of the other options, including a safe start for MySQL, but none worked.

Here is one that does:

At least for the version I got 5.7.28-0ubuntu0.18.04.4 answers were lacking IDENTIFIED WITH mysql_native_password. 5.7.28 is the default on the current LTS and thus should be the default for most new new systems (till Ubuntu 20.04 (Focal Fossa) LTS comes out).

I found Can't set root password MySQL Server and now applied

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_pass_here';

which does work.

Solution 23:^[23]

The error that I faced was:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

It was a problem with the port running on.

By default, MySQL is running on port 3306.

You can check that on by running

in a 32-bit system:

sudo /opt/lampp/manager-linux.run
in a 64-bit system:

sudo /opt/lampp/manager-linux-x64.run

and click on the Configure button.

In my case the port was running on 3307, and I used the command

mysql -u root -p -P 3307 -h 127.0.0.1

Solution 24:^[24]

Copied from this link, I had the same problem and this solved the problem. After we add a password for the database, we need to add -p (password-based login), and then enter the password. Otherwise, it will return this error:

mysql -u root -p

Solution 25:^[25]

I had a similar issue:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

But in my case, the cause was really silly. I copied the command from a Word document, and the problem was that an hyphen did not have the ASCII 0x2D code but the Unicode 0xE2 0x80 0x93 UTF-8 sequence (codepoint U+2013 EN DASH).

Wrong way:

mysql -u root –pxxxx

Right way:

mysql -u root -pxxxx

Both look the same, but aren't the same (try it, copy and paste replacing your password).

Faced with this type of error, the recommendation is to try typing the command instead of copying and pasting.

Solution 26:^[26]

Because your error message says "PASSWORD: YES" this means you are are using the wrong password. This happened to me also. Luckily I remembered my correct password, and was able to make the DB connection work.

Solution 27:^[27]

In recent MySQL versions there isn't any password in the mysql.user table.

So you need to execute ALTER USER. Put this one line command into the file.

ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

And execute it as an init file (as the root or mysql user):

mysqld_safe --init-file=/home/me/mysql-init &

MySQL server need to be stopped to start mysqld_safe.

Also, there may be a problem with AppArmor permissions to load this init file. Read more in AppArmor and MySQL.

Solution 28:^[28]

If you haven't set password yet, then run mysql -uroot. It works for me.

Solution 29:^[29]

On Mac, if you have a problem in logging in with the first password you were given in installation, maybe you can just simply kill the MySQL process and then try.

So:

run the following command to find the PID of MySQL:
```
ps -aef | grep mysql | grep -v grep
```
kill the process:
```
kill -15 [process id]
```

Then you can log in with the initial password using this command:

mysql -uroot -p

Which asks you to enter your password. Just enter the initial password.
