在对接应用服务时MySQL返回报错：

ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/lib64/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory

因为MySQL8默认使用了新的加密规则caching_sha2_password，而不是之前的规则mysql_native_password。

解决办法

ALTER USER '用户名'@'主机地址' IDENTIFIED WITH mysql_native_password BY '密码';

使用root账号登录MySQL执行sql语句:

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'lolicp.com';
