摘要

在官网下载了mysql，版本mysql-5.7.17-winx64，免安装的压缩包，解压后。放在MySql的文件夹中。电脑系统win10 x64.

配置文件

修改了basedir和datadir配置。

添加环境变量

我的电脑->属性->环境变量-PATH

C:\Program Files\MySql\mysql-5.7.17-winx64\bin;

管理员身份运行CMD，并进入bin目录。安装mysql。命令：mysqld -install

然后启动mysql。

出现这个错误尝试很多方法解决，最后将自己手动创建的data文件夹删除，然后运行初始化命令而解决。

初始化命令：mysqld --initialize

初始化过程中，会data创建很多的文件，如图所示：
