How to reset mysql root password?
(8 answers)
Closed 6 years ago.
I have MySQL 5.6 installed using installer. I have forgotten my password. So I have followed some examples to reset the root pwd for root. The command I gave was this:
C:\Windows\system32>"C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqld.exe" --i
nit-file="c:\\new folder\mysql-init.txt" --explicit_defaults_for_timestamp=true
The command prompt silently returns without starting Mysql. I need to actually reset the password.
Please point out my mistake. Let me know If I am doing something wrong!!

Read this Reset mysql server password.
On Windows, use the following procedure to reset the password for all MySQL root accounts:
1. Log on to your system as Administrator.
2. Stop the MySQL server if it is running. For a server that is running as a Windows service, go to the Services manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list and stop it.
If your server is not running as a service, you may need to use the Task Manager to force it to stop.
3. Create a text file containing the following statements. Replace the password with the password that you want to use.
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
FLUSH PRIVILEGES;
Write the UPDATE and FLUSH statements each on a single line. The UPDATE statement resets the password for all root accounts, and the FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.
4. Save the file. For this example, the file will be named C:\mysql-init.txt.
5. Open a console window to get to the command prompt: From the Start menu, select Run, then enter cmd as the command to be run.
6. Start the MySQL server with the special --init-file option (notice that the backslash in the option value is doubled):
C:\> C:\mysql\bin\mysqld --init-file=C:\\mysql-init.txt
If you installed MySQL to a location other than C:\mysql, adjust the command accordingly.
The server executes the contents of the file named by the --init-file option at startup, changing each root account password.
You can also add the --console option to the command if you want server output to appear in the console window rather than in a log file.
If you installed MySQL using the MySQL Installation Wizard, you may need to specify a --defaults-file option:
C:\> "C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqld.exe"
--defaults-file="C:\\Program Files\\MySQL\\MySQL Server 5.6\\my.ini"
--init-file=C:\\mysql-init.txt
The appropriate --defaults-file setting can be found using the Services Manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list, right-click it, and choose the Properties option. The Path to executable field contains the --defaults-file setting.
7. After the server has started successfully, delete C:\mysql-init.txt.
You should now be able to connect to the MySQL server as root using the new password. Stop
the MySQL server, then restart it in normal mode again. If you run the server as a
service, start it from the Windows Services window. If you start the server manually,
use whatever command you normally use.

As I have commented the procedure did not complete successfully. I have tried numerous combinations and remembered the password.

mysql won't change my root password,

I'm having a serious troublesome situation trying to reset my MySQL's root password. I'm following the dev.mysql.com instructions:
Step 1. Log on to your system as Administrator.
Step 2. Stop the MySQL server if it is running. For a server that is running as a Windows service, go to the Services manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list and stop it.
If your server is not running as a service, you may need to use the Task Manager to force it to stop.
Step 3. Create a text file containing the password-assignment statement on a single line. Replace the password with the password that you want to use.
MySQL 5.7.6 and later:
ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
MySQL 5.7.5 and earlier:
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('MyNewPass');
Step 4. Save the file. This example assumes that you name the file C:\mysql-init.txt.
Step 5. Open a console window to get to the command prompt: From the Start menu, select Run, then enter cmd as the command to be run.
Step 6. Start the MySQL server with the special --init-file option (notice that the backslash in the option value is doubled):
C:\> cd "C:\Program Files\MySQL\MySQL Server 5.7\bin"
C:\> mysqld --init-file=C:\\mysql-init.txt***
That's where I'm stuck: step 6. I did everything accordingly, and cmd gives me back:
mysqld: CAN'T CHANGE DIR TO 'C:Program Files\MySQL\MySQL SERVER 5.7\data\'
<Errcode: 2 - No such file or directory>
0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.
Please use --explicit_defaults_for_timestamp server option<see documentation for more details>
0 [Note] --secure-file-priv is set to NULL. Operations related to importing and exporting data are disabled
...
PS: I've saved the mysqld-init.txt in the Local Disk(C:).
Please guys, I don't have a clue on how to solve this mess. I need to reset the root password and connect MySQL.
Thanks
This question is about half a year old, but I just ran into the same problem this morning. Made several changes at the same time, so I'm not sure which was the actual fix, but, regarding:
mysqld: CAN'T CHANGE DIR TO 'C:Program Files\MySQL\MySQL SERVER 5.7\data\'
I created an empty 'data' directory in the "MySQL SERVER 5.7" folder.
Additionally, I used an 'Administrator: Command Prompt' to execute the command. Finally, I included the "defaults file" specified in the MySQL docs, and fiddled with the order of inputs. I've closed the window now, but I don't believe I actually used "double backslashes".
My working command was:
mysqld.exe --defaults-file="C:\ProgramData\MySQL\MySQL Server 5.7\my.ini"
--init-file="C:\Users\Me\mysql-init.txt"
--console

Setting up mySQL db and TomCat on Windows for a website

I've been searching everywhere, and I just can't wrap my head around the procedure that lies in setting a server up with some schemas to be used along a website.
I'm using workbench, but also the command line way.
I have two desktop computers. One that I want for normal use. And the second to be put up as a mySQL database, and just that. The need here is that the database PC, should allow some kind of remote access, so that my website may connect to it.
Installing MySQL Server in windows is easy, however first access have a small tricks. Start by downloading MySQL Server from here:
http://dev.mysql.com/downloads/mysql/
During the install don't forget to check the options to add MySQL to the System Path Variables.
After that you'll have to reset the root password. For some weird reason the root password doesn't work (at least on windows). Follow the instructions here:
http://dev.mysql.com/doc/refman/5.1/en/resetting-permissions.html
To make it shorter:
1) Type services.msc in start menu to open the service lists
2) Stop MySQL server
3) Create a txt file with the content below, placing the commands in 2 lines.
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
FLUSH PRIVILEGES;
4) Execute this command on a DOS prompt
"C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld.exe" --defaults-file="C:\Program Files\MySQL\MySQL Server 5.5\\my.ini" --init-file=C:\\arquivo.txt --console
The init-file must point to the file created in item (3)
5) Delete the file created, restart MySQL service and logon normally with root user
To test your login, use a DOS prompt and type
mysql -h 127.0.0.1 -u root -pMyNewPass (no spaces between "P" and your password).

I have been installing the MySQL Community Server from ZIP Archive with the Inno Setup. I have used this install script (little modified) http://dark-it.blogspot.sk/2009/07/inno-setup-mysql-full-script.html, because I need one-click installation for my very simple application, which works with the MySQL database. My Installation to the Windows XP Professional was successful. Now the MySQL service is running correctly. But my problem is that I don´t know the username and the password for connect to this MySQL server. I have tried changed the username and the password in my.ini file but it wasn´t correct. And I tied blank password too. Can I somehow change the username and the password in this file? Or what is the default password after install? I need import my prepared database to one-click install too. I have located this database to /MyApplication/Data/Database_folder. In this directory are folders as test and performance_schema too. It is correct location?
Thanks for reply.
See the MySQL developer pages how to reset the root password.
Log on to your system as Administrator.
Stop the MySQL server if it is running. For a server that is running as a Windows service, go to the Services manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list and stop it.
If your server is not running as a service, you may need to use the Task Manager to force it to stop.
Create a text file containing the following statements. Replace the password with the password that you want to use.
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
FLUSH PRIVILEGES;
Write the UPDATE and FLUSH statements each on a single line. The UPDATE statement resets the password for all root accounts, and the FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.
Save the file. For this example, the file will be named C:\mysql-init.txt.
Open a console window to get to the command prompt: From the Start menu, select Run, then enter cmd as the command to be run.
Start the MySQL server with the special --init-file option (notice that the backslash in the option value is doubled):
C:> C:\mysql\bin\mysqld-nt --init-file=C:\mysql-init.txt
If you installed MySQL to a location other than C:\mysql, adjust the command accordingly.
The server executes the contents of the file named by the --init-file option at startup, changing each root account password.
You can also add the --console option to the command if you want server output to appear in the console window rather than in a log file.
If you installed MySQL using the MySQL Installation Wizard, you may need to specify a --defaults-file option:
C:> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld-nt.exe"
--defaults-file="C:\Program Files\MySQL\MySQL Server 5.0\my.ini"
--init-file=C:\mysql-init.txt
The appropriate --defaults-file setting can be found using the Services Manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list, right-click it, and choose the Properties option. The Path to executable field contains the --defaults-file setting.
After the server has started successfully, delete C:\mysql-init.txt.
You should now be able to connect to the MySQL server as root using the new password. Stop the MySQL server, then restart it in normal mode again. If you run the server as a service, start it from the Windows Services window. If you start the server manually, use whatever command you normally use.
About importing you database I would prefer to use a SQL dump they are usually smaller and simple to install with something like this:

How to start MySQL server on windows xp

Whenever I try to start MySQL by typing
> mysql -u root
I get the error
ERROR 2003(HY000): Can't connect to MySQL server on 'localhost' (10061)
How can I solve the problem above? I just downloaded MySQL and unzipped it in the E: drive. I have not done anything else. Do I have to make a connection first? If so, how can I do that?
Here is the ZIP file that I had downloaded: mysql-5.7.15-winx64.zip
Here are the steps to start MYSQL Server (mysql-5.7.15-winx64) for the first time on Windows:
Create a new folder named "data" in MYSQL installation directory (i.e. in the same location as where "bin" directory is located. For me it is: C:\programs\mysql-5.7.15-winx64\mysql-5.7.15-winx64. This location will vary as per the location where you have extracted the MYSQL zip file)
From here I will use my MYSQL folder location as reference. Go to: C:\programs\mysql-5.7.15-winx64\mysql-5.7.15-winx64\bin and execute the command: mysqld --initialize-insecure or mysqld --initialize depending on whether you want the server to generate a random initial password for the 'root'#'localhost' account.
To start the DB, go to: C:\programs\mysql-5.7.15-winx64\mysql-5.7.15-winx64\bin and execute mysqld --console You can see the start-up logs being printed.
To connect to DB, go to: C:\programs\mysql-5.7.15-winx64\mysql-5.7.15-winx64\bin and execute mysql -u root -p. When prompted, Enter password if it has been set or else just hit "Enter" button to connect
The MySQL server can be started manually from the command line. This can be done on any version of Windows.
To start the mysqld server from the command line, you should start a console window (or “DOS window”) and enter this command:
shell> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld"
The path to mysqld may vary depending on the install location of MySQL on your system.
You can stop the MySQL server by executing this command:
shell> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqladmin" -u root shutdown
**Note : **
If the MySQL root user account has a password, you need to invoke mysqladmin with the -p option and supply the password when prompted.
This command invokes the MySQL administrative utility mysqladmin to connect to the server and tell it to shut down. The command connects as the MySQL root user, which is the default administrative account in the MySQL grant system. Note that users in the MySQL grant system are wholly independent from any login users under Windows.
If mysqld doesn't start, check the error log to see whether the server wrote any messages there to indicate the cause of the problem. The error log is located in the C:\Program Files\MySQL\MySQL Server 5.0\data directory. It is the file with a suffix of .err. You can also try to start the server as mysqld --console; in this case, you may get some useful information on the screen that may help solve the problem.
The last option is to start mysqld with the --standalone and --debug options. In this case, mysqld writes a log file C:\mysqld.trace that should contain the reason why mysqld doesn't start. See MySQL Internals: Porting to Other Systems.

If the command prompt does not work in Windows, try the following:
1) Open services in Windows.
2) Then check the status for Mysql and if you found status nothing or blank then start the mysql service.
3) After then see whether the mysql is start or not .If it shows started then try to check mysql working.
It has worked for me when cmd commands were not working.
Run the command prompt as admin and cd to bin directory of MySQL
Generally it is (C:\Program Files\MySQL\mysql-5.6.36-winx64\bin)
Run command : mysqld --install. (This command will install MySQL services and if services already installed it will prompt.)
Run below commands to start and stop server
To start : net start mysql
To stop : net stop mysql
Run mysql command.
Enjoy !!
maybe
E:\mysql-5.1.39-win32\bin>mysql -u root -p
Type
C:\> "C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld" --console
to start the sql server and then test the client connection.
I was using MySQL Server 5.5 as a result I was missing the folder which majority of the answers made mention of in the bin folder. What I did instead was the following:
Open Explorer and make your way to C:\Program Files\MySQL\MySQL Server 5.5\bin or your MySQL installation directory.
Run the executable application MySQLInstanceConfig and follow the images below.
This solved my issue and I was able to access the database without any errors.
Start mysql server by command prompt
C:> "C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld" --console
Or alternative reach up to bin then
mysqld --console
It will start your server.
If you have mysql command line client available
click on it
it show enter your password :
Please enter your password.
Then you can access it.
You also need to configure and start the MySQL server. This will probably help
I tried following steps to run mysql server 5.6 on my windows 8.
Run command prompt as an administrator
go mysql server 5.6 installation directory (in my case: C:\Program Files (x86)\MySQL\MySQL Server 5.6\bin) copy that location
In Command prompt run "cd C:\Program Files (x86)\MySQL\MySQL Server 5.6\bin"
run "mysql -u root"
You need to run the server first. The command you use (in the question) starts a client to connect to the server but the server is not there so there the error.
Since I am not a Windows user (Linux comes equipped) so I might not be the best person to tell you how but I can point to you to a guide and another guide that show you how to get MySQL server up and running in Windows.
After you get that running, you can use the command (in the question) to connect it.
NOTE: You may also try http://www.apachefriends.org/en/xampp.html if you plan to use MySQL for web database development.
Hope this helps.
The error complains about localhost rather than permissions and the current practice in MySQL is to have a bind-address specifying localhost only in a configuration file.
So I don't think it's a password problem - except that you say you 'unzipped' MySQL.
Is that enough installation? What did you download?
Was there any installation step which allowed you to define a root password?
And, as NawaMan said, is the server running?
first thing you need to do is to start the mysql
for that you can use
E:\mysql-5.1.39-win32\bin>net start mysql (only when there a mysql running as service)
then you can execute
E:\mysql-5.1.39-win32\bin>mysql -u root
Run your command prompt as administrator.#
We can start MySQL service from windows command line using the below command.
net start mysql
Command to stop MySql service:
net stop mysql
Disable MySql service:
sc config mysql start= disabled
Command to enable MySql service(to automatically start MySQL service when the system starts up):
sc config mysql start= auto
Command to set the startup type to manual:
sc config mysql start= manual
How to restart MySql service?
There is no direct command to restart a service. You can combine stop and start commands like below.
net stop mysql & net start mysql
I was also having problem with starting MySql server but run command as mention right mark in picture . Its working fine .
mysql -u root -p
After entering this command in terminal, it will ask for password
Enter the password and you are ready to go!
there is one of the best solution do resolve this problem and it is going to work 100%.
as we know that server is a process so treat it like a process go to the task manager
in windows and see for services in task manager in that service see for Mysql and MS80 and try to start it manually by click on it and say run then will take some time.
go to your mysql workbench and click on start/shutdown then try to refresh the server status in server status option. it will load up thats it.
1.Open a command prompt as Administrator.
2.Go to MySQL installed bin directory in program files.
3.Copy the location of the bin directory from windows explorer.
4.In command prompt type cd and (paste the location) and do enter.
5.Type mysqld --initialize
6.Open services from the windows menu and sort the list by name.
7.Right-click Mysql and click start.
use the command "mysql -u root -p" in the bin folder path.
and give the MY SQL password which you have set earlier.

How do I retrieve my MySQL username and password?

I lost my MySQL username and password. How do I retrieve it?
Stop the MySQL process.
Start the MySQL process with the --skip-grant-tables option.
Start the MySQL console client with the -u root option.
List all the users;
SELECT * FROM mysql.user;
Reset password;
UPDATE mysql.user SET Password=PASSWORD('[password]') WHERE User='[username]';
But DO NOT FORGET to
Stop the MySQL process
Start the MySQL Process normally (i.e. without the --skip-grant-tables option)
when you are finished. Otherwise, your database's security could be compromised.
Unfortunately your user password is irretrievable. It has been hashed with a one way hash which if you don't know is irreversible. I recommend go with Xenph Yan above and just create an new one.
You can also use the following procedure from the manual for resetting the password for any MySQL root accounts on Windows:
Log on to your system as Administrator.
Stop the MySQL server if it is running. For a server that is running as a Windows service, go to
the Services manager:
Start Menu -> Control Panel -> Administrative Tools -> Services
Then find the MySQL service in the list, and stop it. If your server is
not running as a service, you may need to use the Task Manager to force it to stop.
Create a text file and place the following statements in it. Replace the password with the password that you want to use.
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
FLUSH PRIVILEGES;
The UPDATE and FLUSH statements each must be written on a single line. The UPDATE statement resets the password for all existing root accounts, and the FLUSH statement tells the server to reload the grant tables into memory.
Save the file. For this example, the file will be named C:\mysql-init.txt.
Open a console window to get to the command prompt:
Start Menu -> Run -> cmd
Start the MySQL server with the special --init-file option:
C:\> C:\mysql\bin\mysqld-nt --init-file = C:\mysql-init.txt
If you installed MySQL to a location other than C:\mysql, adjust the command accordingly.
The server executes the contents of the file named by the --init-file option at startup, changing each root account password.
You can also add the --console option to the command if you want server output to appear in the console window rather than in a log file.
If you installed MySQL using the MySQL Installation Wizard, you may need to specify a --defaults-file option:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld-nt.exe" --defaults-file="C:\Program Files\MySQL\MySQL Server 5.0\my.ini" --init-file=C:\mysql-init.txt
The appropriate --defaults-file setting can be found using the Services Manager:
Start Menu -> Control Panel -> Administrative Tools -> Services
Find the MySQL service in the list, right-click on it, and choose the Properties option. The Path to executable field contains the --defaults-file setting.
After the server has started successfully, delete C:\mysql-init.txt.
Stop the MySQL server, then restart it in normal mode again. If you run the server as a service, start it from the Windows Services window. If you start the server manually, use whatever command you normally use.
You should now be able to connect to MySQL as root using the new password.
An improvement to the most useful answer here:
1] No need to restart the mysql server
2] Security concern for a MySQL server connected to a network
There is no need to restart the MySQL server.
use FLUSH PRIVILEGES; after the update mysql.user statement for password change.
The FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.
The --skip-grant-options enables anyone to connect without a password and with all privileges. Because this is insecure, you might want to
use --skip-grant-tables in conjunction with --skip-networking to prevent remote clients from connecting.
from: reference: resetting-permissions-generic
Do it without down time
Run following command in the Terminal to connect to the DBMS (you need root access):
sudo mysql -u root -p;
run update password of the target user (for my example username is mousavi and it's password must be 123456):
UPDATE mysql.user SET authentication_string=PASSWORD('123456') WHERE user='mousavi';
at this point you need to do a flush to apply changes:
FLUSH PRIVILEGES;
Done! You did it without any stop or restart mysql service.
While you can't directly recover a MySQL password without bruteforcing, there might be another way - if you've used MySQL Workbench to connect to the database, and have saved the credentials to the "vault", you're golden.
On Windows, the credentials are stored in %APPDATA%\MySQL\Workbench\workbench_user_data.dat - encrypted with CryptProtectData (without any additional entropy). Decrypting is easy peasy:
std::vector<unsigned char> decrypt(BYTE *input, size_t length) {
DATA_BLOB inblob { length, input };
DATA_BLOB outblob;
if (!CryptUnprotectData(&inblob, NULL, NULL, NULL, NULL, CRYPTPROTECT_UI_FORBIDDEN, &outblob)) {
throw std::runtime_error("Couldn't decrypt");
}
std::vector<unsigned char> output(length);
memcpy(&output[0], outblob.pbData, outblob.cbData);
return output;
}
Or you can check out this DonationCoder thread for source + executable of a quick-and-dirty implementation.
If you have root access to the server where mysql is running you should stop the mysql server using this command
sudo service mysql stop
Now start mysql using this command
sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &
Now you can login to mysql using
sudo mysql
FLUSH PRIVILEGES;
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('MyNewPass');
Full instructions can be found here http://www.techmatterz.com/recover-mysql-root-password/
Login MySql from windows cmd using existing user:
mysql -u username -p
Enter password:****
Then run the following command:
mysql> SELECT * FROM mysql.user;
After that copy encrypted md5 password for corresponding user and there are several online password decrypted application available in web. Using this decrypt password and use this for login in next time.
or update user password using flowing command:
mysql> UPDATE mysql.user SET Password=PASSWORD('[password]') WHERE User='[username]';
Then login using the new password and user.
After MySQL 5.7.6 and MariaDB 10.1.20 (currently in 2022) you can:
Update a mysql user password having access to root user
ALTER USER 'some_user_name'#'localhost' IDENTIFIED BY 'a_super_secure_password';
Update mysql root user
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password by 'mynewpassword';
List all users
select user from mysql.user;
IF you happen to have ODBC set up, you can get the password from the ODBC config file. This is in /etc/odbc.ini for Linux and in the Software/ODBC folder in the registry in Windows (there are several - it may take some hunting)
Save the file. For this example, the file will be named C:\mysql-init.txt.

Although a strict, logical, computer science'ish interpretation of the op's question would be to require both "How do I retrieve my MySQL username" and "password" - I thought It might be useful to someone to also address the OR interpretation. In other words ...
1) How do I retrieve my MySQL username?
OR
2) password
This latter condition seems to have been amply addressed already so I won't bother with it. The following is a solution for the case "How do i retreive my MySQL username" alone. HIH.
To find your mysql username run the following commands from the mysql shell ...
SELECT User FROM mysql.user;
it will print a table of all mysql users.
