From your Show slave status G
output, the following things can be understood:
Slave_IO_Running: Yes
It means, Input Output thread is running - this thread is responsible for downloading data (binlog) from master server to slave server.
Slave_SQL_Running: Yes
It means, SQL thread is running - this thread is responsible for executing SQL from relay log (from binlog).
Read_Master_Log_Pos: 402
,Exec_Master_Log_Pos = 402
, It means, the IO thread reading from the binary log position 402 and the SQL thread executing the same query.
Seconds_Behind_Master: 0
It means, both the master and slave is in sync and slave is in up-to the point, no delay.
Slave_SQL_Running_State: Slave has read all relay log; waiting for more updates.
It means slave is up to the point.
It seems, slave is getting data from master and there is no issues in your settings.
FYI:
- Run the
Show Slave Status G
command continuously, you will see the following variable values will change, every time.
Master_Log_File: mysql-bin.000033
Read_Master_Log_Pos: 402
Relay_Log_File: VoltyLinux-relay-bin.000046
Relay_Log_Pos: 317
Exec_Master_Log_Pos: 402
Relay_Log_Space: 692
In case, if your slave stopped getting data from master server, you will see the No
value for Slave_IO Running
variable in your Show Slave Status G
command output as follows.
Slave_IO_Running: NO
I hope this answer will help you. Thanks.

@RickJames If master data replicated to slave, the values will change. However, we can define the maximum size limit for log files (binary log & relay log), once the max limit reached, log files names will change. I tried to answer in simple language, so may be few things change a bit. Thank you.

In non-busy systems, Log_files may change only once a week. A busy system might see them change once an hour. But not "every time you runSHOW SLAVE STATUS
".

Simple way just create a test database on master server and see if it got created on slave server (assuming no time lagging).

@RickJames If master data replicated to slave, the values will change. However, we can define the maximum size limit for log files (binary log & relay log), once the max limit reached, log files names will change. I tried to answer in simple language, so may be few things change a bit. Thank you.

In non-busy systems, Log_files may change only once a week. A busy system might see them change once an hour. But not "every time you runSHOW SLAVE STATUS
".

Simple way just create a test database on master server and see if it got created on slave server (assuming no time lagging).

"change every time"? I don't think so.

Just to clarify: with "sync" you mean that changes on master are not propagated to the slave, right? What are the
server_id
s of the servers? (run:show global variables like 'server_id'
on both the slave and the master). Please also include the master status from the master host. Do you have any replication filters enabled?– Károly Nagy
