Mysql – RDS slave (read replica) not replication

Hey I know a crazy method to create a slave without augmenting any operation of master (ServerA) or slave (ServerB)

Step 1) Setup a New Server (ServerC)

Step 2) On ServerC, Install MySQL (same version as ServerB)

Step 3) On ServerC, service mysql stop

Step 4) Copy /etc/my.cnf from ServerB to ServerC

Step 5) On ServerC, change server_id to a value different from ServerA and ServerB

Step 6) rsync /var/lib/mysql on ServerB to ServerC

Step 7) When rsync is completed, run "STOP SLAVE;" on ServerB

Step 8) rsync /var/lib/mysql on ServerB to ServerC

Step 9) On ServerB, run "START SLAVE;"

Step 10) On ServerC, service mysql start

Step 11) On ServerC, run "START SLAVE;" (Do this if skip-slave-start is in /etc/my.cnf)

Give it a Try !!!

BTW I have the utmost confidence this will work because I just did this for client over the last 2 days. Client had 2.7TB of data on a slave. I rsyncd to another server while the slave was still active. rsync took like 11 hours. I then ran STOP SLAVE; on the first slave and ran rsync again. That took another hour. I then performed the above step and everything is done.

I think I see the problem

You have the following in your question:

Replicate_Do_DB: db1; db2

That is not supposed to be a semicolon-separated list. It is supposed to be a comma-separated list.

My guess is your have this in your slave's /etc/my.cnf

replicate-do-db=db1; db2

The correct way to set this up is

replicate-do-db=db1
replicate-do-db=db2

Please adjust this in the slave's /etc/my.cnf and restart mysql on the slave

Give it a Try !!!

You may want to clear out the relay log by doing this

STOP SLAVE;
CHANGE MASTER TO master_log_file='mysql-bin.000008',master_log_pos-98;
START SLAVE;

then run SHOW SLAVE STATUS\G and make sure replication is running by making sure you see this

Slave_IO_Running: Yes
Slave_SQL_Running: Yes

just as you posted in your question
