1. 备份 cancer 数据库
“`
mysql show databases;
+——————–+
| Database |
+——————–+
| information_schema |
| mysql |
| cancer |
| cancer_utf8 |
| performance_schema |
| test |
+——————–+
6 rows in set (0.05 sec)
“`
2. 备份的方向符号为 ()
“`
[root@mysql 3306]# mysqldump -uroot -p -S /data/3306/mysql.sock cancer /opt/cancer_bak.sql
Enter password:
“`
3. 查看备份的语句
“`
[root@mysql 3306]# egrep -v #|\*|–|^$ /opt/cancer_bak.sql
DROP TABLE IF EXISTS `student`;
CREATE TABLE `student` (
`id` int(4) NOT NULL AUTO_INCREMENT,
`names` char(20) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
LOCK TABLES `student` WRITE;
INSERT INTO `student` VALUES (1, ???),(2, è???”·?-?
UNLOCK TABLES;
“`
4. 备份恢复的方向符号为 ()
“`
[root@mysql 3306]# mysql -uroot -p -S /data/3306/mysql.sock cancer /opt/cancer_bak.sql
“`
加 - B 的备份与恢复
1. 备份
“`
[root@mysql 3306]# mysqldump -uroot -p -S /data/3306/mysql.sock -B cancer /opt/cancer_bak_B.sql
Enter password:
[root@mysql 3306]# cd /opt
[root@mysql opt]# diff cancer_bak.sql cancer_bak_B.sql
18a19,26
— Current Database: `cancer`
—
CREATE DATABASE /*!32312 IF NOT EXISTS*/ `cancer` /*!40100 DEFAULT CHARACTER SET latin1 */;
USE `cancer`;

“`
2. 恢复
“`
[root@mysql opt]# mysql -uroot -p -S /data/3306/mysql.sock /opt/cancer_bak_B.sql
“`
3. 压缩备份
“`
[root@mysql opt]# mysqldump -uroot -p -S /data/3306/mysql.sock -B cancer|gzip /opt/cancer_bak_gzip.sql.gz
Enter password:
“`
4. 备份多个库
“`
[root@mysql opt]# mysqldump -uroot -p -S /data/3306/mysql.sock -B cancer cancer_utf8 /opt/cancer_mul_bak
Enter password:
“`
5. 多库备份脚本
“`
[root@mysql opt]# mysql -uroot -p -S /data/3306/mysql.sock -e show databases; |grep -Evi database|infor|perfor |sed -r s#^([a-z].*$)#mysqldump -uroot -pcancer -S /data/3306/mysql.sock -B –events \1|gzip /opt/\1.sql.gz#g |bash
Enter password:
“`
脚本的显示内容
“`
mysqldump -uroot -pcancer -S /data/3306/mysql.sock -B mysql|gzip /opt/mysql.sql.gz
mysqldump -uroot -pcancer -S /data/3306/mysql.sock -B cancer|gzip /opt/cancer.sql.gz
mysqldump -uroot -pcancer -S /data/3306/mysql.sock -B cancer_utf8|gzip /opt/cancer_utf8.sql.gz
mysqldump -uroot -pcancer -S /data/3306/mysql.sock -B test|gzip /opt/test.sql.gz
“`
1. 备份具体某个库中的某个表
“`
[root@mysql ~]# mysqldump -uroot -p -S /data/3306/mysql.sock cancer student test
Enter password:
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `student` (
`id` int(4) NOT NULL AUTO_INCREMENT,
`names` char(20) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
/*!40101 SET character_set_client = @saved_cs_client */;
INSERT INTO `student` VALUES (1, ???),(2, è???”·?-?
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `test` (
`id` int(11) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
/*!40101 SET character_set_client = @saved_cs_client */;
“`
2. 只备份表结构
“`
[root@mysql ~]# mysqldump -uroot -p -S /data/3306/mysql.sock -d cancer
Enter password:
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `student` (
`id` int(4) NOT NULL AUTO_INCREMENT,
`names` char(20) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
/*!40101 SET character_set_client = @saved_cs_client */;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `test` (
`id` int(11) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
/*!40101 SET character_set_client = @saved_cs_client */;
“`
“`
[root@mysql ~]# mysqldump -uroot -p -S /data/3306/mysql.sock -d cancer student
Enter password:
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `student` (
`id` int(4) NOT NULL AUTO_INCREMENT,
`names` char(20) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
/*!40101 SET character_set_client = @saved_cs_client */;
“`
3. 只备份数据
“`
[root@mysql ~]# mysqldump -uroot -p -S /data/3306/mysql.sock -t cancer student
Enter password:
INSERT INTO `student` VALUES (1, ???),(2, è???”·?-?
“`
