卸载MySQL
- 笔者由于跟着网上的教程将MySQL安装到了C盘,忘记了可以走更改路径这条路,在卸载MySQL的路上一去不复返。
- 试过网上诸多重装方案,大体均为以下步骤:控制面板卸载MySQL→删除注册表→删除ProgramData、Application Data、Program Files (x86)、Program Files里面的MySQL→删除环境变量,然后重启。
- 最终打开的安装包依旧是“welcome back”
- 一度令我想要重装系统
以上这种情况就是没有卸载干净
- 于是尝试了一个新的方法,借助geek软件删除有关MySQL的所有文件夹、注册表等信息。
- 下面放一个geek百度网盘下载版:百度网盘 提取码:7rbo
- 功夫不负有心人,终于卸载完毕了
重装MySQL
- 成功进行重新安装,出现的页面会和第一次安装一样,如果不是,则表示还没有删干净。
- 存档一个MySQL安装教程:MySQL+Navicat安装配置教程(超级详细、保姆级)
- 笔者安装的是最新版,与链接安装的版本不同,即没有链接中的提示→【若电脑中没有这个环境,会提示安装“Microsoft Visual C++ 2013”环境】
- 因此,需要自行下载一个Microsoft Visual C++ 2013。
- 存档一个Microsoft Visual C++ 2013链接:百度网盘

- 装上Vcredist.x86即可执行【笔者需要重启电脑才成功】。
