mysql启动报错：本地计算机上的mysql服务启动后停止,某些服务在未由其他服务或程序使用时将自动停止
新电脑上安装mysql报错。PS压缩包。注意以下cmd操作全部在对应的/bin目录下操作的
- 解压后直接配置path
- 修改my-default.ini文件。

mysqld --install mysql - 启动服务：
net start mysql - 报错：
查找问题，重新安装，找到问题原因，配置文件有误，还有就是未初始化mysql data文件夹。修改步骤如下：
- 删除mysql服务
mysqld --remove mysql - 修改配置文件中的[mysql] [mysqld] ！！注意这两个括号里面的 不能少。详细的见上面的inip配置（我贴的已经是正确的了，之前我两个括号里面都写的是[mysqld]）
- 重新安装mysql服务
mysqld --install mysql - 初始化data
mysqld --initialize-insecure - 启动mysql服务
net start mysql
