replyWell, I found a problem, because the mysql service name in the phpstudy environment is MySQLa, and when mysql is upgraded, mysqld --install is not specified and the service name defaults to MySQL, so you only need to delete the previous MySQL service and re-specify the service name. , attach the command
mysqld --remove MySQL
mysqld --install MySQLa
Manual upgrade MYSQL service is not added to PHPSTUDY
Additionally, in the phpstudy integrated environment. (I didn’t notice that the question asked is no longer on the phpstudy official website)
