概述
- MariaDB数据库管理系统是MySQL的一个分支，主要由开源社区在维护，采用GPL授权许可 MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能轻松成为MySQL的代替品。在存储引擎方面，使用XtraDB来代替MySQL的InnoDB。 MariaDB由MySQL的创始人Michael Widenius主导开发，他早前曾以10亿美元的价格，将自己创建的公司MySQL AB卖给了SUN，此后，随着SUN被甲骨文收购，MySQL的所有权也落入Oracle的手中。MariaDB名称来自Michael Widenius的女儿Maria的名字。
- MariaDB基于事务的Maria存储引擎，替换了MySQL的MyISAM存储引擎，它使用了Percona的 XtraDB，InnoDB的变体，分支的开发者希望提供访问即将到来的MySQL 5.4 InnoDB性能。这个版本还包括了 PrimeBase XT (PBXT) 和 FederatedX存储引擎。
安装部署
