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?
