結合mysql replication那篇文章，只是把mydump備份使用了innobackupex工具替代，其他操作基本一樣。使用innobackupex不需要手動鎖表操作，鎖表時間更短，備份更加快。
master:192.168.1.1 slave:192.168.1.2
master上進行備份操作
innobackupex --user=root --password=xxxxxx --host=127.0.0.1 --port=3306 --stream=tar
--defaults-file=/etc/my.cnf /tmp/| ssh [email protected] "mkdir /db; tar xfi - -C /db/"
innobackupex 以steam方式拷貝主服務器上的datadir目錄中的數據到到從服務器/db。
slave停止mysql服務
/etc/init.d/mysqld stop
#rm /var/lib/mysql/* -rf #刪除原始數據
#innobackupex --host=127.0.0.1 --user=root --password=xxxxx --port=3306 --apply-log /db/
#innobackupex --host=127.0.0.1 --user=root --password=xxxxx --port=3306 --copy-back /db/
cat /db/xtrabackup_binlog_info #查看二進制的日誌和pos

查看Slave_IO_Running,Slave_SQL_Running如果都是yes,則replication perfect！
