two。 Extract to server C disk directory, customizable

Note here that if you don't edit anything, just follow these steps to start:

Failed to start mysql service

5. When installing mysql version 5.7 +, if you find that the data folder is missing in the root directory, please do not copy the data folder of other versions, because this operation will cause many potential problems. If you copy it, please delete it first.

You need to automatically generate the data directory and execute it in cmd.

6. At this point, the directory is complete. Open my-defult.ini and edit as follows:

Just configure it according to your own directory. Then start the MySql service again:

MySql started successfully.

If prompted "not internal or external commands", pay attention to whether the directory is wrong, or to configure environment variables, how to configure, please program for Baidu.

8. The default MySql does not have a password, which needs to be changed manually

Mysql > set password = password ('your password'); mysql > flush privileges

9. Connecting to MySql with a visual tool will indicate that the current ip cannot connect. Authorization is required for root.

Mysql > grant all on *. * to 'root'@'%' IDENTIFIED BY' your password 'with grant option; mysql > flush privileges

10. Try to connect again and you can enter.

Mysql > use mysql;mysql > update user set password=password ('your password') where user='root'; mysql > flush privileges
