开源存储之ceph

小记,曾经的很多单骑,赵子龙,杨再兴,..............为大将者所应用的胆识和气度,值得敬仰!

名师出高徒啊,

周侗北宋末年之武术大师,相传为三国姜维的传人(真实性ruiy哥就不考察了哈)，后拜少林派武师谭正芳为师，得少林武术真传;
大徒弟卢俊义
二徒弟林冲
三徒弟史文恭(虽是,叛徒坏人,但实力也是很可观的)
义子岳飞
不记名徒弟武松
以上非个人观点,看官自辨;

咱不扯淡,俗话说的好,胜王,败寇;搞定即是王道,直接主题不瞎扯淡;

ceph配置 for centos6.4

1,yum repo配置整理

别的配置根据如下

setup ceph nodes

看看那sshpasswordless还是很重要的,在大数据,云环境,大多数分布式群集环境中多需要sshPDless,ruiy之前农工过sshPDless简单维护工具请感兴趣的另行;

倒是puppet,chef等数据中心群集配置管理不要ssh,但这又说回来了,人家这些可是C/S架构,有中央Server,他们内部通讯靠的是CS以维护的信任证书;

配置ceph节点

下面就是配置ceph中央服务器池与从节点间的sshpasswordless;

快速搞定,仅仅是案例脚本,请根据你的具体测试或是应用场景环境自行简单修改;
