2. Description
Steps that describe the problem and how to resolve it:
-
During MySQL installation with MySQL, you might find the following error:
ERROR 1682 (HY000): Native table 'performance_schema'.'session_variables' has the wrong structure
-
Then try to upgrade mysql server using binaries provided by the mysql server installation:
>> /path/to/mysql/5.7/bin/mysql_upgrade --defaults-file=/root/.mysql_secret-5.7
It should complete without error. That will be indicated by the command. It might happen MySQL server is already upgraded. In such case you will get something like:
This installation of MySQL is already upgraded to 5.7.13, use --force if you still need to run mysql_upgrade
Do not force. It means it was upgraded but for some reason, it was not restarted. Try first to restart before forcing anything.
-
Restart MySQL server upgraded to make changes to take effect:
>> /etc/init.d/mysql-5.7 restart
-
After this, try again to run query that was failing with this error.
