Don’t tell me about downloading and unzipping
I unzipped it at: E:DBFilesmysql-5.7.15-winx64mysql-5.7.15-winx64
Add configuration file E:DBFilesmysql-5.7.15-winx64mysql-5.7.15-winx64my.ini

The data directory is no longer included in the zip package and needs to be initialized: mysqld --initialize
Then perform service registration: E:DBFilesmysql-5.7.15-winx64mysql-5.7.15-winx64bin>mysqld install MySQL --defaults-file="E:DBFilesmysql-5.7.15-winx64mysql-5.7.15-winx64my.ini"
Prompt installation successful
After the service is successfully registered, start the MySQL service. The MySQL service can be started successfully. When logging in as the root user, you will be prompted to enter a password. The root password has not been set at this time
Stop the service and add a configuration of skip-grant-tables=1 in my.ini to allow password skipping. After modification, restart the MySQL service. The root user can log in normally
After logging in, change the password using alter user root identified by 'root'
Tip: The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
Then refer to the Internet and use: update user set authentication_string=PASSWORD('root') where User='root'; you can modify it successfully
Change the password through update user set authentication_string=password('root') where user ='root', and it will prompt success
After changing the password, remove the skip-grant-tables=1 configured above, log in with the root user and the password root you just set, no problem,
But when I use mysql to switch data, I am prompted to change my password?
Then I executed: alter user 'root'@'localhost' identified by 'root';
It’s finally better now
Then you can connect normally using the HeidiSQL management tool:
When changing the password in the middle, use: alter user 'root'@'localhost' identified by 'root';
Tip: The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
Then refer to the Internet and use: update user set authentication_string=PASSWORD('root') where User='root'; you can modify it successfully
But during the restart, I was asked to change the password again, using: alter user 'root'@'localhost' identified by 'root'; This completes the change of the root password.
In the past, I installed it through the next step. This time, I installed mysql through uninstall. Due to repeated testing, I encountered many problems in the process. It took three times to succeed.
The above is the entire description of the noinstall method for installing mysql 5.7.5 m15 winx64 under Windows introduced by the editor. I hope it will be helpful to you. If you have any questions, please leave me a message and the editor will reply to you in time. , I would also like to thank everyone for your support of the website!
