1、先去MySQL官网下载。当前最新版是5.7.19,可能安装方法不同了,本人测试没有安装成功,若有安装成功的朋友,希望分享一下安装步骤。

个人推荐下载MySQL5.7.17,官方下载网址:https://downloads.mysql.com/archives/community/,然后选择5.7.17然后下载即可。

2、将下载的压缩包解压出来,然后在“MySQL解压目录”中新建“data”文件夹。如下图:

3、将“my-default.ini”复制一份,并改名为:“my.ini”(如上图中的my.ini),修改“basedir”指向“MySQL解压目录”,“datadir”指向MySQL解压目录下的“data”(data为第二步自己创建的)。 my.ini内容如下:

# Remove leading

4、为了方便,配置一下环境变量。

  4.1、新增系统变量:  MYSQL_HOME : 你的MySQL解压目录

5、准备工作已完成,接下来就开始真正的安装了:

  1、以管理员启动命令行,注意以”管理员“形式启动。

  2、输入命令:mysqld --initialize-insecure

  Windows中 MySQL5.7.17解压版安装步骤_qt_06

  该命令是初始化数据库得到data目录,执行完之后你会发现data中生成了一些文件。

  3、接着执行命令:mysqld --install  若出现 Service successfully installed.则说明安装成功!

   4、执行命令:net start mysql 启动MySQL服务,出现如下如说明服务已经成功启动

  5、跟换MySQL root用户密码:

    5.1 登录MySQL: mysql -uroot -p,首先是没有密码的

    5.2 修改密码:set password for root@localhost = password('123456');

 

到这里就算全部安装完成。。。。。希望此文章可以对你有帮助。。。。。
