Moving MySQL Cold Backup to Another DB Server
You missed three(3) things


On DB1, mysql -uroot -ppassword -e"SET GLOBAL innodb_fast_shutdown = 0"
On DB1, service mysql stop (DB1)
Copying the backup (/var/lib/mysql) on DB1
Copy /etc/my.cnf on DB1 to /etc folder on DB2
Importing DB1 backup to DB2 (/var/lib/mysql)
On DB2, chown -R mysql:mysql /var/lib/mysql
Start mysql on DB2


Step 1 flushes everything InnoDB not yet committed to disk. That makes for a faster mysql startup.

From here, you have the option of changing settings

Give it a Try !!!
