Centos 1, 5.4
Mysql 5.1.xx is directly installed using rpm
Xtrabackup 1.2.22 directly installed with rpm

[Mysqld]
Server-id = 1
Log-bin
Innodb_flush_log_at_trx_commit = 1
Sync_binlog = 1
Datadir =/var/lib/mysql
Character-set-server = utf8
Init_connect = 'set NAMES utf8'

If the default character set is set to utf8, you can choose this configuration as needed.

Grant replication slave on *.*
TO' '@' '
Identified' ';

4. Master: export data to slave
Xtrabackup is used to back up mysql. the advantage is that the lock table time on the master node is very short and can be used in the actual production environment. xtrabackup automatically records the location of the synchronization log file.

Sudo innobackupex-1.5.1 -- stream = tar/tmp/| ssh "Mkdir/tmp/db; tar xfi--C/tmp/db /"

In this step, the master data, including the entire table structure, is exported, compressed, copied to slave, and decompressed to the/tmp/db directory of slave.

5. Slave: import data to slave

Innobackupex-1.5.1 -- apply-log/tmp/db
Innobackupex-1.5.1 -- copy-back/tmp/db
Chown-R mysql. mysql/var/lib/mysql /*

6. Slave: start data synchronization

MASTER_USER =' ',
MASTER_PASSWORD =' ',
MASTER_LOG_FILE =' ',
MASTER_LOG_POS = ;
