mysqlbinlog: unknown variable 'default-character-set=utf8'

Today when I try to check the log-bin file, encounter an error:
mysqlbinlog: unknown variable 'default-character-set=utf8'
it's because inside the my.cnf  got
default-character-set=utf8


the default-character-set is deprecated in 5.5. we should use instead:

character-set-server = utf8

 

or add ----no-defaults

 

mysqlbinlog --no-defaults -v logbin-log.000003 > logbin003.sql

MySQL 5.6 GTID replication "doesn't exists on query" error fix

Master-slave environment encounter error 1858, it's happening when drop an object on master, but the object doesn't on slave , this is the error:

 Last_SQL_Error: Error 'Can't drop database 'dba1'; database doesn't exist' on query. Default database: 'dba1'. Query: 'drop database dba1'
firstly I try to skip this error:
mysql> set global sql_slave_skip_counter=1;
ERROR 1858 (HY000): sql_slave_skip_counter can not be set when the server is running with @@GLOBAL.GTID_MODE = ON. Instead, for each transaction that you want to skip, generate an empty transaction with the same GTID as the transaction
Oops, GTID can't use sql_slave_skip_counter any more, try to generate a null transaction to skip the error, check the binlog file and get the last gtid
mysql> show binary logs;

Show slave status\G again, that error transaction skip already, master-slave working fine.
