For the impatient, here is the quick snippet of how backup and restore MySQL database using mysqldump:

代码如下 复制代码

backup: # mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql

restore:# mysql -u root -p[root_password] [database_name] < dumpfilename.sql


1. Backup a single database:
This example takes a backup of sugarcrm database and dumps the output to sugarcrm.sql

代码如下 复制代码

# mysqldump -u root -ptmppassword sugarcrm > sugarcrm.sql

# mysqldump -u root -p[root_password] [database_name] > dumpfilename.sqlThe sugarcrm.sql will contain drop table, create table and insert command for all the tables in the sugarcrm database. Following is a partial output of sugarcrm.sql, showing the dump information of accounts_contacts table:

代码如下 复制代码

-- Table structure for table `accounts_contacts`
--

DROP TABLE IF EXISTS `accounts_contacts`;
SET @saved_cs_client = @@character_set_client;
SET character_set_client = utf8;
CREATE TABLE `accounts_contacts` (
`id` varchar(36) NOT NULL,
`contact_id` varchar(36) default NULL,

) ENGINE=MyISAM DEFAULT CHARSET=utf8;
SET character_set_client = @saved_cs_client;
