使用MyISAM和InnoDB表备份MySQL数据库

Question

I have a MySQL database with mixed up tables (MyISAM, InnoDB).

How can I create a full backup of the database with mysqldump via Linux command line, what option should I use?

Answer 1

use below-

Generic command for all db's is-

mysqldump -uroot -proot123 -A > /path/mydbbackup.sql

If you want to take few or all db's as per your choice then-

mysqldump -uroot -proot123 -B mydb1 mydb2 mydb3 > /path/mydbbackup.sql

If you want to avoid locking then use single transaction option-

mysqldump --single-transaction -uroot -proot123 -A > /path/mydbbackup.sql

If you want to take specific db backup then-

mysqldump -uroot -proot123 mydb > /path/mydbbackup.sql

If you want to take a table backup then-

mysqldump -uroot -proot123 mydb mytable > /path/mydbbackup.sql

where username is root and password is root123, you can change as per your's

Note: mysqldump utility takes innodb and myisam both backups.

Answer 2

There is no convenient solution currently:

• MyISAM tables need the option --lock-tables
• InnoDB tables need the option --single-transaction --skip-lock-tables

Both options are mutually exclusive. You must select databases first and then dump them separately.

Or...

If you have databases with both types of tables, just run mysqldump twice...
