请问Mysql5.7没有data文件夹的问题怎么解决?

尝试了很多做法没有成功,难道要卸载重装?
安装完成后C:\Program Files\MySQL\目录下没有data文件
图片说明
运行show databases:没有反应

在C:\ProgramData\MySQL\隐藏文件下找到了Data文件和my.ini如图图片说明
求救!!
另外xampp也是显示错误

4个回答

1 前一阶段要用moodle,在安装XAMPP一体包的时候没遇到过

2 参考这个博客http://jingyan.baidu.com/article/eae07827baa2a51fec548527.html

3 不过我遇到了另一个问题,就是阿帕奇(apache)的需要更新到最新的版本

mySQL还是比较好卸载的,只需要在控制面板里卸载即可,再重新装一遍就好了

图不太清楚,感觉图中show database结尾是冒号,这是不对的。
应该以 分号 结束命令

问题已经解决了 data文件在隐藏目录下貌似并不影响运行

CentOS7安装MySQL5.7.18的问题
MySQL5.7.18 tar压缩包安装到CentOS7上后默认没有my.cnf配置文件的,此时可以正常启动,正常访问数据库。但是将配置文件放到/etc/my.cnf处后,MySQL就无法启动了,提示pid文件不存在 ``` Starting MySQL.. ERROR! The server quit without updating PID file (/usr/local/mysql/data/mysql.pid). ``` /usr/local/mysql/data/mysql.pid是我在my.cnf中定义的pid-file 该配置文件可在CentOS6中的MySQL5.6.36正常使用。 当我再次删除配置后,mysql又可以正常启动,可以在/usr/local/mysql/data目录下看到localhost.localdomain.pid文件。 为什么添加配置文件后反而不生成pid文件了?如果不使用配置文件又该如何控制MySQL性能?

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
