MySQL从库应用日志卡住

Posted 2022-12-11 Demonson

SELECT * FROM information_schema.`PROCESSLIST` WHERE command<>'sleep';

Reading event from the relay log

SHOW relaylog EVENTS IN 'mysql-relay-bin.000059' FROM 890792001 LIMIT 500 ;

查到是SET @@SESSION.GTID_NEXT= 'ANONYMOUS'事件卡住

# 卡在这个SET @@SESSION.GTID_NEXT= 'ANONYMOUS' ，不知道是啥，把这个event跳过
STOP SLAVE ;
SET GLOBAL sql_slave_skip_counter=1;
START SLAVE;

再次查看从库和主库之间差距是不是有缩小

SELECT * FROM information_schema.`PROCESSLIST` WHERE command<>'sleep';
