root user doesn't have privileges for administration

I have a newly installed mysql instance.
I need to have the root user be the administrator.
Version is mysql  Ver 8.0.20-11 for Linux on x86_64 (Percona Server (GPL), Release 11, Revision 5b5a5d2)
Running in centos 7.8.2003(core)

I did a sudo start service mysql and that created all the data file/directories.
I log in as root to mysql but I have hardly any privs and cant even see the mysql database.

@ipcmlr  I can’t seem to reproduce your case. I have the same setup running Percona Server for MySQL 8.0.20 on CentOS 7 and started the mysqld instance. Logged in and was required to changed root temp password.
I would suggest initializing the data directory after move the data directory since your setup seems like a fresh instance.

@jrivera thanks. It worked.
Looking back now I think it may have been something to do with me changing the root password and using mysql_config_editor for passwordless login.
