这篇文章主要介绍了解决Mysql5.7.17在windows下安装启动时提示不成功问题,需要的朋友可以参考下
在机器上首次安装MySQL,
操作系统是win7
mysql 的安装文件是 zip 格式的,版本是5.7.17
解压之后,安装步骤是
1、首先找个文件存放这些安装程序以及 数据
假设是E:\\mysql
2、把解压的文件放在E:\\mysql下,并且新建个data文件夹
3、创建环境变量mysql 路径是E:\\mysql
添加到path 中 %MYSQL%\bin;
4、在解压的文件夹下有个my-default.ini
的文件,首先拷贝一份,重命名为my.ini
修改文件内容
只修改两行就行
basedir = E:\\mysql datadir = E:\\mysql\\data
这两行原先是用#号注释掉的,
5、用系统管理员身份启动命令行
输入mysqld -install
这个是安装mysql 服务的
6、输入 mysqld --initialize
这个是因为 自动5.7.7版本之后,windows安装mysql通过zip解压的方式,不再包含data 文件夹,
如果没有data文件夹,则会在启动mysql服务的时候起不来,观察data文件夹下后缀名是.err的文件就可以发现,会报这么一些错误

其实这是因为这些表示放在data文件夹下的,所以我们需要先执行命令mysqld -initialize
在完成mysql 的初始化,这样的话,mysql会自动完成一些初始化的工作
7、启动服务 net start mysql
