mysql8.0.11安装成功后初始化临时密码报错

安装mysql8.0.11成功后查看mysql版本号

PS C:\WINDOWS\system32> mysql --version
C:\Software\mysql-8.0.11-winx64\bin\mysql.exe  Ver 8.0.11 for Win64 on x86_64 (MySQL Community Server - GPL)

执行初始化命令mysqld --initialize --console报错

以管理员身份打开cmd进入到MySQL的bin目录，执行命令mysqld --initialize --console
命令mysqld --initialize --console的作用是使MySQL初始化并得到临时密码。

PS C:\Software\mysql-8.0.11-winx64\bin> mysqld --initialize --console
2018-10-31T03:18:05.201142Z 0 [System] [MY-013169] [Server] C:\Software\mysql-8.0.11-winx64\bin\mysqld.exe (mysqld 8.0.11) initializing of server in progress as process 2356
2018-10-31T03:18:05.231148Z 0 [ERROR] [MY-010457] [Server] --initialize specified but the data directory has files in it. Aborting.
2018-10-31T03:18:05.242682Z 0 [ERROR] [MY-010119] [Server] Aborting
2018-10-31T03:18:05.251312Z 0 [System] [MY-010910] [Server] C:\Software\mysql-8.0.11-winx64\bin\mysqld.exe: Shutdown complete (mysqld 8.0.11)  MySQL Community Server - GPL.

出现报错
[ERROR] [MY-010457] [Server] --initialize specified but the data directory has files in it. Aborting.

问题原因以及解决方法

mysql安装目录下data文件夹有数据，导致报错。

data文件夹的作用：
1、存放ibdata（所有数据库的信息都在这里）；
2、存放数据库的文件夹，比如有个数据库叫teacher，那么会有个teacher文件夹，存放teacher数据库的所有文件。

解决办法：将data文件夹清空。

重新执行命令mysqld --initialize --console

PS C:\Software\mysql-8.0.11-winx64\bin> mysqld --initialize --console
2018-10-31T03:24:15.995649Z 0 [System] [MY-013169] [Server] C:\Software\mysql-8.0.11-winx64\bin\mysqld.exe (mysqld 8.0.11) initializing of server in progress as process 19760
2018-10-31T03:24:26.177747Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: #ld(EIl4XmA.
2018-10-31T03:24:31.063614Z 0 [System] [MY-013170] [Server] C:\Software\mysql-8.0.11-winx64\bin\mysqld.exe (mysqld 8.0.11) initializing of server has completed

得到临时密码#ld(EIl4XmA

使用临时密码登录MySQL并修改密码

输入命令 mysql -u root -p

 PS C:\Software\mysql-8.0.11-winx64\bin> mysql -u root -p
Enter password: ************
