Solution to the problem of unsuccessful installation and startup of Mysql5.7.17 under Windows

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
