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

部署docker下的mysql时出现以下报错

[root@docker ~]# mysql -h192.168.30.22 -uroot -p

Enter password:

出现报错：

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

原因应该是mysql版本问题
