本机远程连接发现身份认证出现问题
mysql8-2059 Authentication plugin ‘caching_sha2_password’ cannot be loaded
原因
mysql8 之前的版本中加密规则是mysql_native_password,而在mysql8之后,加密规则是caching_sha2_password
解决方案
一种是升级navicat驱动,一种是把mysql用户登录密码加密规则还原成mysql_native_password.
mysql> alter user ‘root’@’%’ identified with mysql_native_password by ‘我的密码这个隐藏掉’;
Query OK, 0 rows affected (0.01 sec)
mysql> select user ,plugin from user
-> ;
±-----------------±----------------------+
| user | plugin |
±-----------------±----------------------+
| root | mysql_native_password |
| mysql.infoschema | caching_sha2_password |
| mysql.session | caching_sha2_password |
| mysql.sys | caching_sha2_password |
±-----------------±----------------------+

这里发现已经把root的远程登陆加密规则还原掉了
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
尝试远程登陆成功
mysql> ^C
mysql> exit
Bye
