解压

解压之后没有my.ini文件（我的端口设置的3308），截图中是我增加的

[client]
port = 3308
default-character-set = utf8
 
[mysqld]
port = 3308
character_set_server = utf8
 
basedir=D:\MySQL\mysql-8.0.13-winx
datadir=D:\MySQL\mysql-8.0.13-winx\data
 
group_concat_max_len=20000
 
 
[WinMySQLAdmin]
D:\MySQL\mysql-8.0.13-winx\bin\mysqld.exe

管理员命令行

在MySQL安装目录的 bin 目录下执行命令：

mysqld --initialize --console

得到如下结果

D:\MySQL\mysql-8.0.13-winx\bin>mysqld --initialize --console
2018-10-24T05:32:45.732454Z 0 [System] [MY-013169] [Server] D:\MySQL\mysql-8.0.13-winx\bin\mysqld.exe (mysqld 8.0.13) initializing of server in progress as process 43080

D:\MySQL\mysql-8.0.13-winx\bin>

看到有个警告，查了一下mysql建议使用utf8mb4

修改my.ini文件

[client]
port = 3308
default-character-set = UTF8MB4 
 
[mysqld]
port = 3308
character-set-server = UTF8MB4 
 
basedir=D:\MySQL\mysql-8.0.13-winx
datadir=D:\MySQL\mysql-8.0.13-winx\data
 
group_concat_max_len=20000
 
 
[WinMySQLAdmin]
D:\MySQL\mysql-8.0.13-winx\bin\mysqld.exe

警告没有了

D:\MySQL\mysql-8.0.13-winx\bin>mysqld --initialize --console
2018-10-24T06:06:51.100372Z 0 [System] [MY-013169] [Server] D:\MySQL\mysql-8.0.13-winx\bin\mysqld.exe (mysqld 8.0.13) initializing of server in progress as process 47804
2018-10-24T06:07:18.372699Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: nj>uUJkpH4/I
2018-10-24T06:07:36.024435Z 0 [System] [MY-013170] [Server] D:\MySQL\mysql-8.0.13-winx\bin\mysqld.exe (mysqld 8.0.13) initializing of server has completed
 
D:\MySQL\mysql-8.0.13-winx\bin>

上面打印了默认密码：nj>uUJkpH4/I

安装服务

mysqld --install MySQL8.0

因为这是电脑上第二个mysql 所以服务名改成了 MySQL8.0

启动服务

net start MySQL8.0

修改初始密码

登录mysql之后执行

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
