有免费的MySQL,为什么还要买? >>>  

MySQL 5.5.44 发布,此版本主要是 bug 修复:

  • InnoDB; Partitioning:The CREATE_TIME column of the INFORMATION_SCHEMA.TABLES table now        shows the correct table creation time for partitioned InnoDB tables. The CREATE_TIME column of the        INFORMATION_SCHEMA.PARTITIONS table now shows the correct partition creation time for a partition of    partitioned InnoDB tables.

    The UPDATE_TIME column of the INFORMATION_SCHEMA.TABLES table now shows when a partitioned InnoDB table was last updated by an INSERTDELETE, or UPDATE. The        UPDATE_TIME column of the INFORMATION_SCHEMA.PARTITIONS table now shows when a partition of a partitioned InnoDB table was last updated. (Bug #69990, Bug #17299181)

  • InnoDB: An assertion was raised on shutdown due to XA PREPARE transactions holding explicit locks.       (Bug #20816223)

  • InnoDB: Removal of a foreign key object from the data dictionary cache during error handling caused the server to exit.  (Bug #20442523)

  • InnoDB:  SHOW ENGINE INNODB STATUS output showed negative reservation and signal count values due to a counter overflow error. (Bug #20417397)

  • InnoDB: Estimates that were too low for the size of merge chunks in the result sorting algorithm caused a server exit.  (Bug #20049521)

  • SHOW VARIABLES mutexes were being locked twice, resulting in a server exit. (Bug #20788853)

  • A Provides rule in RPM .spec files misspelledmysql-embeddedasmysql-emdedded. (Bug #20734434)

  • Under certain conditions, the libedit command-line library could write outside an array boundary and  cause a client program crash.  (Bug #20318154)

  • Host value matching for the grant tables could fail to use the most specific of values that contained wildcard characters. (Bug #20181776)

  • A user with a name of event_scheduler could view the Event Scheduler process list without the        PROCESS privilege. (Bug #20007583, Bug #20754369)

  • SHOW GRANTS after connecting using a proxy user could display the password hash of the proxied user.       (Bug #19817663)

  • For a prepared statement with an ORDER BY  that refers by column number to a GROUP_CONCAT() expression that has an outer reference, repeated statement execution could cause a server exit.       (Bug #19814337)

  • Loading corrupt spatial data into a MyISAM table could cause the server to exit during index building.       (Bug #19573096)

  • Certain queries for the INFORMATION_SCHEMA  TABLES and  COLUMNS tables could lead to excessive memory use when there were large numbers of empty InnoDB tables.  (Bug #72322, Bug #18592390)

  • MySQL failed to compile using OpenSSL 0.9.8e.  (Bug #68999, Bug #16861371)

在Oracle收购SUN之前,MySQL的InnoDB引擎就已经被Oracle收购.
Oracle收购SUN后,对MySQL是大力发展的,社区版源代码依然以GPL协议开放.
数据库排名上,MySQL力压SQL Server上升到第二,这还不包括MariaDB和Percona的份额.

如果Oracle把MySQL闭源,那只会让MariaDB和Percona顺利上位.
Oracle苦心经营那么久,不至于这么蠢.
不过总归有人是担心的,所以Redhat从RHEL7开始用MariaDB替代了MySQL.
Facebook/Google/LinkedIn/Twitter/Alibaba则联合维护的一个开源MySQL分支WebScaleSQL:
https://github.com/webscalesql
Linux上Percona是个不错的选择,紧跟MySQL官方版本,除了改进MySQL,还吸收社区补丁.
比如XtraDB就是Percona针对InnoDB的改进版,Percona还提供了一个内置TokuTek开发的大数据事务存储引擎TokuDB的版本,真心赞.
Percona还提供了一些列企业级的MySQL运维工具,比如percona-toolkit,和InnoDB/XtraDB热备份工具xtrabackup,以及zabbix模板等等.

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
