How to recovery password in MySQL workbench? [duplicate] - mysql

Question

I have actually lost my root password and I need to change it. I follow these steps :
Step # 1: Stop the MySQL server process.
Step # 2: Start the MySQL (mysqld) server/daemon process with the
--skip-grant-tables option so that it will not prompt for a password.
Step # 3: Connect to the MySQL server as the root user.
that we can found on these website : https://www.howtoforge.com/setting-changing-resetting-mysql-root-passwords#recover-mysql-root-password
mysql> use mysql;
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD("TOOR");
mysql> flush privileges;
mysql> quit
First error, so I tried :
mysql> use mysql;
mysql> update user set password=PASSWORD("TOOR") where User='root';
mysql> flush privileges;
mysql> quit
Always the same error said :
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near '("TOO
R") WHERE User='root'' at line 1
How can I resolve this?

Answer 1

as here says:
This function was removed in MySQL 8.0.11
1.if you in skip-grant-tables mode
in mysqld_safe:
UPDATE mysql.user SET authentication_string=null WHERE User='root';
FLUSH PRIVILEGES;
exit;
and then, in terminal:
mysql -u root
in mysql:
ALTER USER 'root'#'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';
2.not in skip-grant-tables mode
just in mysql:
ALTER USER 'root'#'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';

Answer 2

Jus login to mysql with sudo
Sudo mysql
Then
ALTER USER 'root'#'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';
exit;
Test it
mysql -u root -p

Answer 3

Try this:
ALTER USER 'root'#'localhost' IDENTIFIED BY 'newPasswd';

Answer 4

If you are on Windows you can try following steps
Reset MySQL 8.0 root Password in Windows
Stop the MySQL 8.0service from services
Go to path C:\Program Files\MySQL\MySQL Server 8.0\bin and open cmd
Run mysqld --console --skip-grant-tables --shared-memory
Open new cmd in the same path
Run following commands
mysql -u root
select authentication_string,host from mysql.user where user='root';
UPDATE mysql.user SET authentication_string='' WHERE user='root';
Now close both the cmd.
Try to start the MySQL 8.0 service.
Connect using username as root & password as blank.
Change the password from the user management.

Answer 5

Step 1: Create a new file in your root directory( e.g C:)
Step 2: Write this ALTER USER 'root'#'localhost' IDENTIFIED BY 'abc' and save it
Step 3: If your Mysql service is already running, please stop this and open your CMD
Step 4: Go to your Mysql installation directory (e.g C:\Program Files\MySQL\MySQL Server 8.0\bin) and type this command
mysql --init-file=C:/init.sql
Step 5: Execute this command and you are good to go :)

Answer 6

I am using 8.0.23 but had multiple issues. Here are the issues and solutions.
I followed the mysql docs and was able to do the reset, though I had isues. I have provided my solutions and a sample reset script.
Issues
following steps outlined by others had various failures
user running daemon is mysql and I cannot su to mysql id
getting error can't create lock file /var/run/mysqld/mysqlx.sock.lock , mysqld folder is getting deleted by the mysql service.
had to kill -9 mysql process after running, very ugly
Solutions
use steps from https://dev.mysql.com/doc/refman/8.0/en/resetting-permissions.html
use --user=mysql when running mysql commands
Create folder /var/run/mysqld and chown for mysql:mysql before runing comamnds
use mysqladmin shutdown to stop sql after starting it for reset
In the script, I will reset root to New%Password
# create password reset file
cat << EOF >/tmp/deleteme
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'New%Password';
EOF
# create /var/run/mysqld
mkdir /var/run/mysqld
chown mysql:mysql /var/run/mysqld
# start mysqld and run the command
mysqld --init-file=/tmp/deleteme --user=mysql &
# wait for sql to start
while [ ! -f /var/run/mysqld/mysqlx.sock.lock ]; do sleep 1; done
sleep 3
# stop sql
mysqladmin -u root -pNew%Password shutdown
while [ -f /var/run/mysqld/mysqlx.sock.lock ]; do sleep 1; done
#clean up temp file
rm /tmp/deleteme

Answer 7

Using SQLYog you can execute commands
User Creation
CREATE USER 'tester'#'localhost' IDENTIFIED BY 'Pass123#d'
Authorization
GRANT ALL PRIVILEGES ON sakila.* TO 'tester'#'localhost'
Changing Password in MySQL 8.0
ALTER USER 'tester'#'localhost' IDENTIFIED BY 'Pass123#d';
or if u know the authentication_string directly set it to update
UPDATE mysql.user
SET authentication_string='*F9B62579F38BE95639ACB009D79427F2D617158F'
WHERE USER='root'
Changing password in lower versions of mysql
GRANT USAGE ON *.\* TO 'tester'#'localhost' IDENTIFIED BY 'Pass123#d'
SET PASSWORD FOR 'tester'#'localhost' = PASSWORD('Pass123#d');
