Could not execute Delete_rows event on table mysql.__firewall_rules__; Can’t find record in ‘__firewall_rules__’, Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event’s master log mysql-bin.000228, end_log_pos 30423413

报错信息：

Could not execute Delete_rows event on table mysql.__firewall_rules__; Can't find record in '__firewall_rules__', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.000228, end_log_pos 30423413

1032错误，master要删除一条记录，而slave上找不到报错。
临时解决：

stop slave;
set global sql_slave_skip_counter=1;
start slave;

永久解决：

更改my.cnf文件，在Replication settings下添加：

slave-skip-errors＝1032

并重启数据库，然后start salve。
注意：因为要重启数据库，不推荐，除非错误事件太多。
