I have one master and 2 slaves,one is replicating but another slave which is read-only not replicating.

From Master :

show master status; +------------------+----------+--------------+------------------+-----------------------------------------------------------------------------------------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | | +------------------+----------+--------------+------------------+-----------------------------------------------------------------------------------------------------+ | mysql-bin.002490 | 13000479 | | | +------------------------------------------------------------------------------

Slave : Master has sent all binlog to slave; waiting for more updates

  • Look like everything is fine. Why do you think there is still no replication?

  • Everything seems to be fine. Try onething to ensure replication is running that create one table on master & check same on both slave Apr 22, 2020 at 13:21
  • I have created database on master but not replicating, tried 3/4 times. Apr 22, 2020 at 15:23
  • Replication not happening on above slave (details given in question) and in other slave replication happening. Apr 22, 2020 at 15:31
  • If slaves behave differently then they differently configured.

These say that it is replicating:

     Slave_IO_Running: Yes
    Slave_SQL_Running: Yes
           Last_Errno: 0

Seconds_Behind_Master: 0

Check my.cnf on both the Master and Slave -- look for replicate/binlog_do/ignore_... Perhaps you are not allowing some databases or tables to go from (do) the Master or be received by (ignore) the Slave.

The various %read_only variables control whether or not you can connect to the server and write; replicated writes are always allowed on the Slave.
