java - mysql binlog reader from remote server

1. Configure your server to enable binlog in my.cnf file. The bold configurations are required.

## enable binlog
server_id=1
log_bin = /path/to/your/binlogfile.log
expire_logs_days = 10
max_binlog_size = 100M
binlog-format = row

2. Grant REPLICATION SLAVE, REPLICATION CLIENT privileges to user to read binlog from remote server
Login mysql with root user, then run command below:

GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'binloguser'@'%' IDENTIFIED BY '123456a@';

3. Test binlog reading from a remote server 

mysqlbinlog -R -h192.168.146.252 --port=3307 -ubinloguser -p mysql-bin.000001

Note: 

-R option instructs mysqlbinlog command to read the log file from the remote server

-h specify the ip-address of the remote server

-p This will prompt you for the password. 

mysqld-bin.000001 This is the name of the binary log file from the remote server that we are reading here

4. Read binlog with Java

Don't forget to configure iptables to allow vrrp protocol between servers.

Example: 
# Allow keepalived
-I INPUT -i eth1 -d 224.0.0.0/8 -p vrrp -j ACCEPT
-I OUTPUT -o eth1 -d 224.0.0.0/8 -p vrrp -j ACCEPT
-I INPUT -i eth2 -d 224.0.0.0/8 -p vrrp -j ACCEPT
-I OUTPUT -o eth2 -d 224.0.0.0/8 -p vrrp -j ACCEPT
