MySql slaves on Amazon EC2 RHEL 7.6 server not getting connected automatically after mysql service restart on...
I have setup MySQL Master - slave replication on Amazon EC2 instance.
OS : RHEL 7.6
MySQL Version: 8.0.13
Mater server IP : 192.168.1.128
Slave server IP : 192.168.1.129
I have two ec2 instance on which i have configured one ec2 as Master and another one as its slave.
I have created user "replicator" on master server for replication with " %" host.
After executing change master statement on slave server as mentioned below.
CHANGE MASTER TO MASTER_HOST='192.168.1.128',MASTER_USER='replicator', MASTER_PASSWORD='Replication@123', MASTER_HEARTBEAT_PERIOD=5, MASTER_LOG_FILE='mysql-bin.000063', MASTER_LOG_POS=195;
I have executed start slave and show slave statusG command on slave server i.e. on 192.168.1.129 .
i have got following error:
Slave_IO_State: Connecting to master
Master_Host: 192.168.1.128
Master_User: replicator
Slave_IO_Running: Connecting
Slave_SQL_Running: Yes
Last_IO_Error: error connecting to master replication@192.168.1.128:3306 - retry-time: 60 retries: 8
Then i have taken login to master mysql server from slave server i.e.
mysql -u replicator -p -h192.168.1.128
slave started sucessfully.
show slave statusG ouput:
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
After all these i came to know that i have to repeat this step i.e. mysql -u replicator -p -h192.168.1.128 from slave server every time whenever master MySQL service restart. Otherwise replication will not take place and we will get the same error as describe above i,e. error connecting to master 'replication@192.168.1.128:3306'
!! Thanks for any help in advance !!
