恢复slave从机上的部分表
以下案例演示重新初始化slave上的个别表,如test01和test02.
1、停止slave复制
2、在master导出这张表,并记录下同步的binlog和POS点
mysqldump -uroot -pmysql -q --single --master-data=2 test test01 test02 > test_01_test_02.sql
3、查看test_01_test_02.sql文件,找到记录的binlog和POS点
MASTER_LOG_FILE='mysql-bin.000003', MASTER_LOG_POS=3407;
4、把test_01_test_02.sql复制到slave上,并做change master指向
直到sql_thread线程为NO,这期间的同步报错一律跳过即可,可用如下命令跳过:
stop slave;
set global sql_slave_skip_counter=1;
start slave;
5、在slave上导入
6、导入完毕之后,开启同步即可。
