Re: databases are lost

[jm L]

Hi,Peter!
Before this, I upgraded mysql.
systemctl stop mysqld
use command:rpm -Uvh mysql-community-common-5.7.33-1.el7.x86_64.rpm mysql-community-libs-5.7.33-1.el7.x86_64.rpm mysql-community-client-5.7.33-1.el7.x86_64.rpm mysql-community-server-5.7.33-1.el7.x86_64.rpm
systemctl start mysqld
Is there a problem with this upgrade process?

This is the MySQL log,table performance_schema there seems to be something wrong.
