1.新建my.ini和data資料夾

建立my.ini 複製以下內容,注意修改路徑,建立data資料夾

[mysqld]
basedir=E:/Program Files/MySQL/MySQL Server 8.0
datadir=E:/Program Files/MySQL/MySQL Server 8.0/data 
port = 3306
character-set-server=utf8
#忘記密碼時使用
#skip-grant-tables
#設定協議認證方式
default_authentication_plugin=mysql_native_password
[mysql]
default-character-set=utf8
 

2.將mysql資料庫user表裡的root使用者的host改成%

update user set host='%' where user='root';

3.允許root使用者遠端訪問

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY '密碼' WITH GRANT OPTION;

4.Navicat11連線mysql8報錯Client does not support authentication protocol requested by server; consider upgrading MySQL client

 ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '密碼';

 FLUSH PRIVILEGES;
