Going by your question, I will like to review what I believe you did thus far:
- You stopped mysql on the Master
- You copied Master's /var/lib/mysql to the Slave's /var/lib/mysql
- I surmise the binlogs on the Master were copied as well
Look at the Slave's last binlog. From the question, it should be
mydbm1-bin.008524
- Filesize 1330529
Believe it or not, you have to do a few things:
1) On the Master, create a replication user like this:
GRANT REPLICATION SLAVE,REPLICATION CLIENT
ON *.* TO replicator@'%'
IDENTIFIED BY 'r3plic4t0R';
2) Make /var/lib/mysql on the Slave owned by mysql
user
chown -R mysql:mysql /var/lib/mysql
3) Make sure Master's server_id is explicitly set in my.cnf
[mysqld]
server_id = 1
4) Make sure Slave's server_id is explicitly set in my.cnf
[mysqld]
server_id = 2
5) Startup mysql on the Slave
service mysql start
6) Setup replication by running this on the Slave
CHANGE MASTER TO
MASTER_HOST='IPAddressOfMaster',
MASTER_PORT=3306,
MASTER_USER='replicator',
MASTER_PASSWORD='r3plic4t0R',
MASTER_LOG_FILE='mydbm1-bin.008524',
MASTER_LOG_POS=1330529;
START SLAVE;
SELECT SLEEP(5);
SHOW SLAVE STATUS\G
You will see something like this:
mysql> show slave status\G

I already answered a post back on Feb 06, 2012 ( How to setup replication(Master/slave) in MySQL 5.5.20? ) with essentially the same steps.
I wanted to add additional posts I made for setting up Circular Replication should you decide to setup the two DB servers as Master/Master
ls -l /var/lib/mysql
SHOW MASTER STATUS;
