备注:关于replicate-wild-do-table

  1. 1 如果同时使用replicate-wild-do-table  replicate-wild-ignore-table

  1. replicate-wild-do-table=test.%
    replicate-wild-ignore-table=test2.%
    那么:主库上的只有test的操作会同步至从库,test2和其它的库都不会同步,新建db 也不会同步

 2.只有replicate-wild-ignore-table 

 replicate-wild-ignore-table= liuliang.%
  那么:主库上只有liuliang库的操作不同步,其它的都同步,并且新建库也会同步!
 

 3.只有replicate-wild-do-table

 replicate-wild-do-table=oauth.%
那么:主库上只有oauth的操作才同步,其它的都不同步,新建的db也不会同步     ===等同于第一种模式!
