1.What is mysqldump ?
mysqldump is a sql based dump, data is dumped then loaded and all indexes are recreated. During mysqldump, all the tables would be locked and will not be accessible for queries.

2.Create test table doudou01 and doudou02
mysql> select * from doudou01;
+----+
| i |
+----+
| 2 |
| 22 |
| 35 |
+----+
3 rows in set (0.00 sec)

3.list of mysqldump sql
[root@dbdou02 ~]# mysqldump -pDoudou123! test doudou01
Warning: Using a password on the command line interface can be insecure.
-- MySQL dump 10.13 Distrib 5.6.29, for Linux (x86_64)

-- Host: localhost Database: test

-- Server version 5.6.29

## Basic information ##

/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
/*!40103 SET @OLD_TIME_ZONE=@@TIME_ZONE */;
/*!40103 SET TIME_ZONE='+00:00' */;
/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;

--
-- Table structure for table `doudou01`
--

DROP TABLE IF EXISTS `doudou01`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `doudou01` (
`i` bigint(20) NOT NULL AUTO_INCREMENT,
PRIMARY KEY (`i`)
) ENGINE=MyISAM AUTO_INCREMENT=36 DEFAULT CHARSET=gbk;
/*!40101 SET character_set_client = @saved_cs_client */;
## create table statement ##
--
-- Dumping data for table `doudou01`
--

LOCK TABLES `doudou01` WRITE;
/*!40000 ALTER TABLE `doudou01` DISABLE KEYS */;
INSERT INTO `doudou01` VALUES (2),(22),(35);
/*!40000 ALTER TABLE `doudou01` ENABLE KEYS */;
UNLOCK TABLES;
/*!40103 SET TIME_ZONE=@OLD_TIME_ZONE */;
## export table data to sql-format ##

/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;
/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;
/*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */;
/*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;
/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;

-- Dump completed on 2016-03-18 15:02:09

4.backup using mysqldump
[root@dbdou02 ~]# mysqldump -uroot -p test doudou01 >doudou01.sql
[root@dbdou02 ~]# mysqldump -uroot -p test doudou02 >doudou02.sql
[root@dbdou02 ~]# ls -l doudou*
-rw-r--r--. 1 root root 1866 Mar 21 11:14 doudou01.sql
-rw-r--r--. 1 root root 2102 Mar 21 11:14 doudou02.sql

5.reloading SQL-Format Backups
5.1 use mysqldump other database
mysql> use test1
