Percona XtraBackup 2.2.8 发布了,XtraBackup 是一个用来备份 MySQLInnoDB 数据库的开源工具。该版本基于 MySQL 5.6.22,修复了一些 bug:

Bugs Fixed:

  • Incremental backups would fail if the number of undo tablespaces (innodb_undo_tablespaces) was more than 1. This was caused by innobackupex removing the undo tablespaces during the prepare phase. Bug fixed #1363234.

  • Fixed multiple memory leaks detected by AddressSanitizer. Bug fixed #1395143.

  • innobackupex could fail when preparing backup that was taken from Percona Server 5.5 with log files (innodb_log_file_size) bigger than 4G. The root cause was that the last checkpoint LSN offset in log group is stored at different offsets in ibdata1 for Percona Server 5.5 and MySQL 5.6 when the total size of log files is greater than 4G. Bug fixed #1403237.

  • Percona XtraBackup out-of-source builds failed. Bug fixed #1402450.

Ubuntu 14.04可以非常方便地通过apt安装Percona官方源提供的二进制包:
http://www.percona.com/doc/percona-server/5.6/installation/apt_repo.html
sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 1C4CBDCDCD2EFD2A
sudo nano /etc/apt/sources.list 加入:
deb http://repo.percona.com/apt trusty main
deb-src http://repo.percona.com/apt trusty main
其中trusty是Ubuntu 14.04的代号,12.04的代号为precise。
sudo apt-get update 更新源,使sources.list生效。
apt-cache search percona 可以看到percona提供的所有工具,比如:
percona-server-server-5.5
percona-server-server-5.6
percona-xtradb-cluster
percona-toolkit
percona-xtrabackup
percona-zabbix-templates
percona-cacti-templates
percona-nagios-plugins

如果你只想安装5.6版本,只需要执行:
sudo apt-get install percona-server-server-5.6
