2. Configure the environment variables of winodws
3. Use the administrator to run the command line window and enter d:/mysql/mysql5716/bin
4. Under mysql/bin, run:
mysqld --install
Relatively, the command to uninstall the service is: mysql --remove MySQL (of course, the service must be stopped first)
5. Under mysql/bin, run:
mysqld --initialize --console
If successful, record the default root@localhost password at the end;
if there is an error message , it may be that the directory configured in my.ini is not found (such as tmpdir, which needs to be manually created in advance)
6. Under mysql/bin, run:
net start MySQL
starts successfully.
7. Under mysql/bin, run:
mysql -uroot -p Press
Enter to connect to mysql, and enter the default password recorded above
8. Enter under mysql>:
use msysql; report the following error message, this is because the first time To enter mysql, you need to change the root password
quote
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
9. Enter under mysql>:
update mysql.user set authentication_string=password('12345678') where user='root' and Host = 'localhost';
change the root password to 12345678. Note: Starting from 5.7, the user table does not have the apssword field, but the authentication_string field.
quote
Query OK, 0 rows affected, 1 warning (0.00 sec)
I installed 5.7.17 once, but running this doesn't work, or you need to reset the password first, and then execute this sentence first:
set password for 'root'@'localhost'=password('12345678');
10. In mysql> Enter:
update mysql.user set host = '%' where user = 'root'; In this way, mysql can use the client tool to connect remotely.
11. Finally, under mysql> enter:
flush privileges;
12. Under mysql/bin, run:
net stop MySQL
to stop mysql, and then run:
net start MySQL
to complete the restart.
At the beginning, the 5th step was not executed, and the mysql service could not be started. Later, after checking the information, it was found that after the mysql5.7.7 version, the decompressed version no longer comes with data initialization data, and step 5 needs to be performed to initialize mysql.
