mysqld --console

从错误信息 mysqld: File '.\binlog.000062' not found (OS errno 2 - No such file or directory) 可以得知 mysql-8.1.0-winx64\data 目录下缺失了 binlog.000062 文件。

解决方案

为了解决这个问题，我们可以尝试删除mysql-8.1.0-winx64\data目录下所有binlog开头的文件，然后重新启动mysql服务。

# 删除binlog文件
del /Q D:\Development\MySQL\mysql-8.1.0-winx64\data\binlog.*
# 重新启动mysql
net start mysql

成功启动mysql服务后，我们可以再次尝试登录到MySQL数据库：

mysql -u root -p

Enter password: ****
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 8.1.0 MySQL Community Server - GPL
