phpstudy启动服务之后navicat for mysql连接不上,一直出现1045错误

mysqladmin -h hostname flush-privileges
use mysql; update user set password =password('yourpass') where user='root'
出现无法连接数据库的话，命令行用root用户登陆，敲下面命令：
SET PASSWORD FOR sns@'localhost'=OLD_PASSWORD('sns');
然后刷新mysql权限
FLUSH PRIVILEGES;
导入数据的方法 mysql -u name -p --default-character-set=utf8 databasename < path\*.sql

create database name character set utf8;
如果出现#1251 - Client does not support authentication protocol requested by server;的错误：
解决办法：先用root登录MYSQL服务器，执行

mysql>set password for user1@"localhost"=old_password('yourPassword');
