2、在D:\database\mysql-8.0.13-winx64新建my-default.ini檔案

[mysqld]
# 設定3308埠
port=3308
# 設定mysql的安裝目錄
basedir=D:\database\mysql-8.0.13-winx64
# 設定mysql資料庫的資料的存放目錄
datadir=D:\database\mysql-8.0.13-winx64\data

#tmpdir=D:\database\mysql-8.0.13-winx64\temp
# 允許最大連線數
max_connections=200
# 允許連線失敗的次數。
max_connect_errors=10
# 服務端使用的字符集預設為UTF8
character-set-server=utf8
# 建立新表時將使用的預設儲存引擎
default-storage-engine=INNODB
# 預設使用“mysql_native_password”外掛認證
#mysql_native_password
default_authentication_plugin=mysql_native_password
[mysql]
# 設定mysql客戶端預設字符集
default-character-set=utf8
[client]
# 設定mysql客戶端連線服務端時預設使用的埠
port=3308
default-character-set=utf8
 

3、已管理員方式開啟CMD視窗，初始化資料庫，這裡一定要用全路徑方式，

D:\database\mysql-8.0.13-winx64\bin>D:\database\mysql-8.0.13-winx64\bin\mysqld.exe --initialize-insecure

D:\database\mysql-8.0.13-winx64\bin>D:\database\mysql-8.0.13-winx64\bin\mysqld.exe --install MySQL3308 --defaults-file=D:\database\mysql-8.0.13-winx64\my-default.ini
Service successfully installed.

D:\database\mysql-8.0.13-winx64\bin>net start mysql3308
MySQL3308 服務正在啟動 .
MySQL3308 服務已經啟動成功。
 

4、初次登入資料庫並修改密碼：

D:\database\mysql-8.0.13-winx64\bin>mysql -h localhost -P 3308 -u root -p
Enter password:
