使用InnoDB替代XtraDB

默认MariaDB 10.1和更早的版本会和XtraDB一起编译为默认版本。从MariaDB 10.2开始,InnoDB是默认的存储引擎。

MariaDB starting with 5.5

MariaDB 5.5开始,所有MariaDB标准发行版也会包括InnoDB插件。

要使用InnoDB插件替换XtraDB,你可以在my.cnf文件中添加:

[mysqld]
ignore_builtin_innodb
plugin_load=ha_innodb.so
# 如果你使用软件包安装的mariadb,则不需要下面这行:
plugin_dir=/usr/local/mysql/lib/mysql/plugin
MariaDB until 5.3

对于MariaDB 5.3和更低的版本,所使用的库名为ha_innodb_plugin.so

你可能会基于以下几种原因使用InnoDB替代XtraDB:

  • 你想要在InnoDB/XtraDB之间做压力测试比较性能
  • 你在XtraDB中遇到了Bug
  • 你在XtraDB中遇到了表空间崩溃且无法恢复的问题。在某些情况下,InnoDB在数据恢复方面更好些。
