HomeDatabaseMysql TutorialMySQL5.7设置同步复制过滤不用重启mysql服务进程了

在MySQL5.5/5.6里版本里,设置同步复制过滤,例如设置忽略掉test库的t2表,你需要在my.cnf配置文件里增加: replicate-ignore-table=test.t2 必须重启mysql服务进程才能生效。 在MySQL5.7里,通过一个新的命令,可以支持在线动态修改,而不须重启mysql进程就

在MySQL5.5/5.6里版本里,设置同步复制过滤,例如设置忽略掉test库的t2表,你需要在my.cnf配置文件里增加:

replicate-ignore-table=test.t2

必须重启mysql服务进程才能生效。


在MySQL5.7里,通过一个新的命令,可以支持在线动态修改,而不须重启mysql进程就生效。

Example:

CHANGE REPLICATION FILTER REPLICATE_DO_DB=(db1,db2);
CHANGE REPLICATION FILTER REPLICATE_IGNORE_DB=(db1,db2);
CHANGE REPLICATION FILTER REPLICATE_DO_TABLE=(db1.t1);
CHANGE REPLICATION FILTER REPLICATE_IGNORE_TABLE=(db2.t2);
CHANGE REPLICATION FILTER REPLICATE_WILD_DO_TABLE=('db.t%');
CHANGE REPLICATION FILTER REPLICATE_WILD_IGNORE_TABLE=('db%.a%');
CHANGE REPLICATION FILTER REPLICATE_REWRITE_DB=((from_db, to_db));
