After upgrading MySQL to 5.7.8-rc
and loging to server I got error:
Table 'performance_schema.session_variables' doesn't exist
I can’t find any solution for this. Can you help ?
The mysql_upgrade worked for me as well:
# mysql_upgrade -u root -p --force # systemctl restart mysqld
mysql -u app -p mysql> set @@global.show_compatibility_56=ON;
as per http://bugs.mysql.com/bug.php?id=78159 worked for me.
