MySQL Replication Binlog file position is not being updated

Question

I am setting up the replication but I am facing issue that the binlog file is not being updated when I am executing any query of insert update or even creating a table. Here My Master my.cnf

server-id       = 1
log_bin         = /var/log/mysql/mysql-bin.log
expire_logs_days    = 10
max_binlog_size         = 100M
binlog_do_db        = rep_db

My Master Status is as under:

mysql> show master status\G
 *************************** 1. row ***************************
 File: mysql-bin.000001
 Position: 107
 Binlog_Do_DB: rep_db
 Binlog_Ignore_DB: 
 1 row in set (0.00 sec)

It was updating the binlog file and position in the Master status but something went wrong and its not being updated.

Answer 1

you can check by below 2 ways-

Method1:use sql statement as per below and check in binlog file-

use rep_db;
Execute your update statement here

Method2: Remove your db from binlog_do_db (now all db will be replicate) for testing and restart mysql service. Now check if logs are updating in binlog file.
