根据错误信息，你遇到了一个关于 MySQL 认证插件
caching_sha2_password的问题。这个插件要求共享对象文件caching_sha2_password.so，但在指定的路径/usr/lib64/mysql/plugin/下找不到该文件。解决此问题的方法是，你可以尝试更改 MySQL 用户的认证插件，以使用较旧的
mysql_native_password插件，这在较旧版本的 MySQL 中更常见。以下是解决方法：mysql> ALTER USER 'zabbix_proxy'@'%' IDENTIFIED WITH 'mysql_native_password' BY 'zabbix';
Query OK, 0 rows affected (0.07 sec)mysql> FLUSH PRIVILEGES;
