Enter password:

`

4. Back up multiple libraries

`

[root@mysql opt] # mysqldump-uroot-p-S / data/3306/mysql.sock-B cancer cancer_utf8 > / opt/cancer_mul_bak

Enter password:

`

5. Multi-library backup script

`

[root@mysql opt] # mysql-uroot-p-S / data/3306/mysql.sock-e "show databases;" | grep-Evi "database | infor | perfor" | sed-r's # ^ ([Amurz]. * $) # mysqldump-uroot-pcancer-S / data/3306/mysql.sock-B-events\ 1 | gzip > / opt/\ 1.sql.gzroomg' | bash

`

The display of the script

`

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. Back up a table in a specific library

`

[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)

/ *! 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 * /

`

two。 Backup list structure only

`

[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. Back up data only

`

[root@mysql] # mysqldump-uroot-p-S / data/3306/mysql.sock-t cancer student

Enter password:

INSERT INTO `student`VALUES (1), (2)
