win10安装mysql-8.0.15-winx64

1、解压将文件放在自己指定的目录（我放在了D:\code\environment\mysql\），之后右键左下角窗口图标启动管理员模式的powershell，进入你放mysql文件的目录，或者直接将msyql的bin文件夹配置到环境变量里去。主要用到bin里的文件。

2、在根目录下配置my.ini文件，我是在网上抄的

3、mysql服务安装，成功会有Service successfully installed提示，

Windows PowerShell
PS D:\code\environment\mysql\mysql-8.0.15-winx64>mysqld install
Service successfully installed.

4、初始化，第二行最后(root@localhost:之后)的乱码是临时密码，之后要用

PS D:\code\environment\mysql\mysql-8.0.15-winx64>mysqld --initialize
2020-02-20T08:57:41.938171Z 0 [System] [MY-013169] [Server] D:\code\environment\mysql\mysql-8.0.15-winx64\bin\mysqld.exe (mysqld 8.0.15) initializing of server in progress as process 4060
2020-02-20T08:57:45.318546Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: #l:mATuai2ie
2020-02-20T08:57:46.594624Z 0 [System] [MY-013170] [Server] D:\code\environment\mysql\mysql-8.0.15-winx64\bin\mysqld.exe (mysqld 8.0.15) initializing of server has completed

5、启动服务

PS D:\code\environment\mysql\mysql-8.0.15-winx64>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。

6、登录，ctrl+c拷贝上面说那串乱码，输密码时右键粘贴即可

PS D:\code\environment\mysql\mysql-8.0.15-winx64>mysql -uroot -p
Enter password: ************

mysql>

7、改密码

 mysql>alter user 'root'@'localhost' identified with mysql_native_password by '12345'

8、可能出现的问题
第4步初始化时出错：

PS D:\code\environment\mysql\mysql-8.0.15-winx64>mysqld --initialize --console
2020-02-20T08:57:07.671252Z 0 [System] [MY-013169] [Server] D:\code\environment\mysql\mysql-8.0.15-winx64\bin\mysqld.exe (mysqld 8.0.15) initializing of server in progress as process 1484
2020-02-20T08:57:07.675506Z 0 [ERROR] [MY-010457] [Server] --initialize specified but the data directory has files in it. Aborting.
2020-02-20T08:57:07.675529Z 0 [ERROR] [MY-013236] [Server] Newly created data directory D:\code\environment\mysql\mysql-8.0.15-winx64\data\ is unusable. You can safely remove it.
2020-02-20T08:57:07.688504Z 0 [ERROR] [MY-010119] [Server] Aborting

把根目录下的data文件删了再来一次，也可能是my.ini文件里有错误，路径要配置正确。

个人总结
