Issues after MYSQL update

Running Debian8 according to the perfect setup for ISPCFG3 inside an LXC.
Updated MYSQL from mysql-community (5.7.14-1debian8) jessie to mysql-community (5.7.15-1debian8) jessie

During the start of MYSQL I see:

Code:

        Sep 10 12:34:38 alfred mysqld: Incorrect definition of table performance_schema.replication_connection_status: expected column 'RECEIVED_TRANSACTION_SET' at position 7 to have type longtext, found type text.
        Sep 10 12:34:38 alfred mysqld: Incorrect definition of table performance_schema.replication_group_member_stats: expected column 'COUNT_TRANSACTIONS_ROWS_VALIDATING' at position 6, found 'COUNT_TRANSACTIONS_VALIDATING'.

MYSQL seems to be running fine but I'm worried about these lines. All I could find so far is this: http://bugs.mysql.com/bug.php?id=59364 which suggests:

Not sure I should blindly follow that advice also, after doing /etc/init.d/mysql stop how would I start it with the --skip-grant-tables option?

 

Use :

Code:

service mysql start --skip-grant-tables

 

thanks, seems to have worked

 

Srsly? This command lets MySQL just ignore the errors, it doesn't fix them! Please do not give answer to stuff you don't understand... Please try the following to actually fix the problem:

Code:

mysql_upgrade

This worked for my Percona Server 5.7 which through the same failures

 

The answer was there, in the quote, sorry for not making it more obvious.

 

Yep, answer was there and Ovidiu had issue with starting server with skip-grant. So I think both of us understand the things correctly here!
