今天安装了navicat 和 mysql，结果最后在navicat中连接mysql时，出现了如下错误提示：
Client does not support authentication protocol requested by server;consider upgrading mysql client
在网上找到的解决办法是:
进入msql
然后输入:
>use mysql;
>alter user 'root'@'localhost' identified with mysql_native_password by '123456';
>flush privileges;
root是用户名,12345是密码.
这样就可以连接了;
