After upgrading MySQL to version 5.7.8-rc and logging into the server, I encountered the following error:
表'performance_schema.session_variables'不存在
I can't find any solution. can you help?
After running the command suggested by @robregonm, I was able to successfully log into the mysql server:
mysql_upgrade -u root -p --force
Need to restart the MySQL server.
mysql_upgrade also works for me:
# mysql_upgrade -u root -p --force # systemctl restart mysqld
good luck, MSz.
