安装mysql8之后没有办法登录,初始密码是多少?
获取初始密码输入以下命令mysqld --initialize --console
mysqld --initialize --console 执行完成后,会输出 root 用户的初始默认密码
2018-04-20T02:35:05.464644Z 5 [Note] [MY-010454] [Server] A temporary password
is generated for root@localhost: APWCY5ws&hjQ
APWCY5ws&hjQ 就是初始密码
如果刚开始没有记住这个密码,那就删除mysql目录下的data文件夹重新进行初始化,使用该命令进行初始化(mysqld
--initialize-insecure),
第一次执行的话,时间会久一些,执行结束后没有输出信息,但是,查看bin的同级目录下会多出一个data文件夹,里面一堆文件。重新执行 (mysqld
--initialize --console),又会重新看到该密码
也可直接修改root帐号的密码
通过net start mysql 启动mysql----启动成功输入mysql -uroot -p
打开客户端连接已经启动的数据库服务 出现Enter直接回车----输入以下命令修改密码为root
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
