Mysql8可视化工具(navicat)连接失败 caching_sha2_password

使用可视化工具链接mysql 8 报错：
ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/local/Percona-Server-5.5.35-rel33.0-611.Linux.x86_64/lib/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory

发现新版MySQL都是默认用caching_sha2_password这个plugin来加密密码了，HeidiSQL无法接入。现改成原生密码的加密方式。

解决办法：

执行：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
flush privileges;
