启动MYSQL报错
网上搜了一大堆,说是配置某文件、删除某文件,都无效。以下亲测有效,PS:MYSQL安装教程
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
说明输入了密码,但是报错。
解决办法:
再次输入:
mysql -u root -p
此时让你输入密码:
Enter password:
此时直接回车,不要输入密码!!!
此时直接回车,不要输入密码!!!
此时直接回车,不要输入密码!!!
重要的事情说三遍!
你会发现,MYSQL成功启动了:(就是这么诡异…)

若希望输入密码启动,则需重新设置密码:
输入:mysql> ALTER user ‘root’@‘localhost’ IDENTIFIED BY ‘123456’;
将密码设置为 123456。(我至今都不知道为何不用密码就能进,而且还需要重新设置密码。但是这么做有效)
mysql> ALTER user 'root'@'localhost' IDENTIFIED BY '123456';
Query OK, 0 rows affected (0.07 sec) # 这句话表示修改成功
再次启动MYSQL
mysql> exit #先输入exit,退出mysql
C:\Windows\system32>mysql -u root -p # 再次启动
Enter password: ****** # 输入密码123456
# 成功...

换一种启动方式
输入:net start mysql80
C:\Windows\system32>net start mysql80
MySQL80 服务正在启动 ..
MySQL80 服务已经启动成功。
