1、之前本博写过一篇在windows下面使用uninstall方式安装MySQL 5.7.9的文章，随着MySQL 8.0 GA版本的发布，预示着8.0作为一个生产环境版本正式走上舞台，有必要将之前的安装方法予以更新，以飨读者。（其实还是用MariaDB开源社区解决方案多）
2、安装平台
Microsoft Windows Server 2016 Standard
MySQL 8.0.11 noinstall archive
3、下载安装包
https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.11-winx64.zip
4、安装布局
| 1 2 3 4 5 6 7 8 9 10 11 12 |
#程序所在位置 C:/mysql #配置文件所在位置 C:/mysql/my.ini #数据文件存放位置 D:/ProgramData/MySQL/data #pid文件位置 D:/ProgramData/MySQL/run #tmp位置 D:/ProgramData/MySQL/tmp #日志文件位置 D:/ProgramData/MySQL/logs |
5、配置my.ini文件
在C:/mysql文件夹下新建my.ini文件，具体内容如下：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 |

6、初始化MySQL
使用管理员打开CMD程序，切换到mysql的bin目录下面，执行如下命令：
| 1 |
mysqld.exe --initialize --basedir="c:/mysql" --datadir="D:/programdata/mysql/data" |
7、启动应用程序
使用–console参数查看输出
| 1 |
mysqld.exe --defaults-file="C:/mysql/my.ini" --console |
–defaults-file参数必须作为mysqld的第一个参数，不然会报“ unknown variable ‘defaults-file=C:/mysql/my.ini’”的错误。
8、登陆MySQL
MySQL初始化的时候会在error.log文件内生成一个临时密码，使用该密码登陆root 用户，将密码进行重置。
| 1 |
alter user 'root'@'localhost' identified by 'yourpassword'; |
9、将MySQL安装为系统服务
| 1 |
mysqld.exe --install MySQL --defaults-file=C:/mysql/my.ini |
若要删除mysql服务，则执行
| 1 |
mysqld.exe --remove |
Enjoy It！祝君使用愉快！
