centos7 開啟 mysql8 遠端控制

mysql8.x密碼的認證方式變了，需要修改遠端認證方式

方法1create user 'root'@'%' identified with mysql_native_password  by '123123';      //修改密碼認證方式為mysql_native_password

grant all on *.* to 'root'@'%';

mysql> create user 'root'@'%' identified with mysql_native_password  by '123123';  # 執行此命令後在遠端使用root賬戶登入，密碼為123456

mysql> grant all on *.* to 'root'@'%'; # 授權
mysql> flush privileges; # 重新整理

方法2create user 'root'@'%' identified by '123123';     //預設的密碼認證外掛程式caching_sha2_password

grant all on *.* to 'root'@'%'; 

alter user 'root'@'%' identified with mysql_native_password by '123123';

mysql> create user 'root'@'%' identified by '123456';  # 執行此命令後在遠端使用root賬戶登入，密碼為123456

mysql> grant all on *.* to 'root'@'%'; # 授權
mysql> alter user 'root'@'%' identified with mysql_native_password by '123456';
mysql> flush privileges; # 重新整理
