What to do if mysql forgets the password

Table of contents

The specific operation of decompressed version installation is as follows:

Then configure our environment variables:

Find system advanced options 

Next click on Environment Variables

 Find the path to edit

 Click New and copy the decompressed path into it (make sure there are decompressed files in our decompressed path)

After configuring the environment variables successfully, next we need to configure the MySQL configuration file.

When we are using Mysql, if we forget the password, it is very troublesome to find it again, so here we teach you another method

We all know that mysql can be installed on our computer in two ways:

                                                                                        Installed version

                                                                                        decompressed version

Installing through the decompressed version does not require a password

So when we forget the password, we can uninstall Mysql and install it through the decompressed version, so that we can reuse our mysql

The specific operation of decompressed version installation is as follows:

 

               

First of all, we need to find the decompressed version of the file, and then decompress it to the file you want to decompress (the decompression path here is very important, it will be used when configuring the environment variables later)

Then configure our environment variables:

Find system advanced options 

Next click on Environment Variables

 Find the path to edit

 Click New and copy the decompressed path into it (make sure there are decompressed files in our decompressed path)

After configuring the environment variables successfully, next we need to configure the MySQL configuration file.

Open the folder you just decompressed (the decompressed folder), create a my.ini configuration file under this folder, and edit my.ini to configure the following basic information:

 

Note: the file in ini format cannot be created directly, so we can first create a text document my.txt in txt format, then edit the above code in this document, and finally rename my.txt to my.ini.

Next, let's start the MySQL database:

Open the cmd command line tool as an administrator, switch the directory to the decompression path

Type in the console

mysqld install

You will see that the service installation is successful

Then initialize data (required after MySQL5.7)

run after initialization

net start mysql

You can start mysql.

Then enter:

mysql -u root

Now that you have entered mysql, then enter

show databases;

When you see the following interface, it proves that you have successfully installed

 

 

 

Then go to the decompressed installation package to find a startup program (the one under the mysql folder)

 

After clicking, install and you can enter Mysql normally.
