新电脑配置安装MySQL解压版

下载地址：（注意下载可能需要ORACLE账号）

mysql下载地址：https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.19-winx64.zip

官网如果不想去下可以参考这篇文章：https://yq.aliyun.com/articles/710422

补充个地址：我自己上传的，避免你懒得高百度账号。

说下需要注意的地方：

1、提示VCRUNTIME140.dll问题。

因为我的电脑是新机。mysqld -install 安装的时候提示，

解决办法：

你缺少那个组件，安装vc2015还是解决不了的，要下载VCRUNTIME140.DLL，地址：https://cn.dll-files.com/vcruntime140.dll.html 解压复制到C:\Windows\System32\这里就行了 删除举报回复

谢谢：@ITwlcsdn

进入这个网址，你下载对应需要的就可以了。我这边下载的是最新的。

2、第二个问题mysqld --initialize --user=mysql --console 出现一大堆信息。

mysqld: Can't create directory 'D: ofts\work\mysql-8.0.19-winx64\data\' (OS errno 2 - No such file or directory)

这个问题应该是无法自动创建data文件导致的。路径的写法问题。

D:\softs\work\mysql-8.0.19-winx64\data我一开始是直接复制的。

要改为D:/softs\work/mysql-8.0.19-winx64/data

数据库管理工具。我自己用sqlyog。下载http://soft.onlinedown.net/soft/24926.htm

自己下载安装就好了。

密码问题：如果你安装的是MySQL8.0以上的版本

D:\softs\work\mysql-8.0.19-winx64\bin>mysqld --initialize --console

这个密码会用得到。下面的操作参考：https://www.cnblogs.com/SunAutumn/p/9155977.html

下一步应该就是：注册或者启动服务器。

没注册就注册下：mysqld -install

启动mysql命令：net start install

登录mysql的命令：mysql -uroot -p

密码：6SVho;S%5tHF

改密码：ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '修改的密码';
