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
