MySQL安装记录

背景

Windows系统重装了, 想恢复一下之前的MySQL环境, 而且本地数据库也是比较常用的, 刚好本次也在安装, 做一个简单的记录. 也算是自己的学习记录输出. 遇到的问题当然也可以同时记录在这里, 方便后
续回顾.

资料包

百度网盘

// TODO 估计放了也会被CSDN屏蔽, 这里就不放了, 后续如果有好的共享磁盘工具, 再分享. 百度网盘也是垃圾, 限速狗. 

下载地址

这里直接给下载源头地址(不太清楚是否需要科学上网):

MySQL官网: https://www.mysql.com

下载地址: https://dev.mysql.com/downloads/installer
我选得是这个:

安装

步骤一: Type and Networking

感觉都是一些简单的配置, 截图如下:

步骤二: Authentication Method

我也是选择默认配置:

步骤三: Accounts and Roles

设置一个密码, 我的是: 1一排2一排逗句, 反正也没人看懂, 哈哈

步骤四: Windows Service

我是直接默认下一步:

步骤五: Service File Permissions

这个目录不知道为啥不能修改, 有点坑啊

步骤六: Logging Options

我这里好像是之前选了高级配置, 才有这个选项.

这里我仔细配置了一下日志目录, 方便更加深入的了解MySQL, 不能简单的为了安装一个软件而安装件, 最好是可以学习到有点东西, 毕竟也花费了一点时间.

步骤七: Advanced Options

步骤八: Apply Configuration

开始配置了:

很快就安装完成了:

问题汇总

问题1: 选择安装包的时候, 有一个32bit是什么意思呢?

问题2: MSI Installer是一个什么安装方式呢?

(已处理)问题3: mysql 不是内部命令

配置环境变量就行. 这里不多赘述了.

解决方案:

把这个目录配置进去, 我是这个目录: C:\Program Files\MySQL\MySQL Server 8.0\bin

(已处理)问题4: 报错了登录不上去

问题截图:

原因分析

命令记错了.

处理方案:

mysqld命令是MySQL的主程序，用来安装初始化；mysql是MySQL的命令行工具；这里因为命令敲成了mysqld -u root -p导致的,正确的命令应该是mysql -uroot -p
