Available today tried it MYSQLHOTCOPY this fast hot standby MYISAM engine tools.
( This article is the case for a single server, multi-server will be added later related operations )
compare his and MYSQLDUMP of:
1, the former is in the sense of a fast COPY file, which is a database-side set of SQL statements.
2, the former can only run on the machine where the directory database, which can be used in remote client. However, the backup file is stored on the server.
3, the same places are performed online TABLES LOCK TABLES and UNLOCK
4, the former need only restore backup files to the source directory COPY be covered, which requires pour SQL files to their original library. ( Source or \ . Or MySQL < backup file )
step by MYSQLHOTCOPY backup:
1, there is no PERL-DBD module installed
on my machine:
[ root @ localhost the Data ] # RPM -qa | grep perl-DBD | grep MySQL
perl - DBD - MySQL - 3 . 0007- . 1 . FC6
2, assign a dedicated database for backup in the user segment
MySQL > Grant SELECT , reload , Lock Tables ON * . * To 'hotcopyer' @ 'localhost' IDENTIFIED by '123456' ;
Query the OK , 0 rows affected ( 0 . 00 sec )
MySQL > flush privileges ;
Query the OK , 0 rows affected ( 0 . 00 sec )
3, add the user's personal or visit /etc/my.cnf master file .my.cnf inside
[mysqlhotcopy]
interactive-timeout
user=hotcopyer
password=123456
port=3306
4、开始备份。
[root@localhost ~]# mysqlhotcopy t_girl t_girl_new
Locked 4 tables in 0 seconds.
Flushed tables (`t_girl`.`category`, `t_girl`.`category_part`, `t_girl`.`id`, `t_girl`.`parent`) in 0 seconds.
