今天配置了台数据库服务器，Intel Xeon 至强四核2.4G， 8G RAM, 320G×2 （组 RAID1）.
总的架构是 CentOS 5.3 (x86_64) 运行在 LVM + RAID1之上。
- RAID1就是镜像备份， 所以2块 320G 的硬盘主板能识别到2块， 而操作系统就只显示单块320G了。
- LVM 能对磁盘进行更灵活的管理。 除了/boot不允许建立在LVM之上， 其他 swap /home /等均建立在LVM上。
- CentOS 5.3 是好东西，可是官方的软件包版本比较滞后， 经常跟不上需求，最后使用了官方源和民间源结合升级的方式， ustc + jasonlitka ， 成功将mysql 及 php各个插件和其他软件包升级， 其中最难伺候的是64位的mysql。
