7. The configuration step[Starting the server and upgrading system tables (may take a long time)]Is taking longer than expected. It is advanced to not cancel the configuration and wait. Configuration steps[启动服务器并升级系统表（可能需要很长时间）]It took longer than expected. It is recommended not to unconfigure and wait. Even after waiting for a whole night to add half a day, I really vomited blood. Although there may be a computer hibernation during the period and a pop-up window that prompts whether to cancel, there is no time to click the wait button. As shown in Figure 5, Figure 6

8. In the end, I decided to give up and restart MySQL Installer as an administrator. Uninstall MySQL Server 8.0.39 . as shown in Figure 7

9. Click the Add button to reinstall, and the initializing database (may take a long time) fails. as shown in Figure 8

10. Check Log, C:\Program Files\MySQL\MySQL Server 8.0\bin\mysqld.exe: An error occurred while setting the value “0.0” to “mysqlx-port”. The parsing option of the plugin “mysqlx” fails.
