Centos7.0安装ceph(JEWEL)及以上版本的实例解析
<p><span><strong>背景</strong></span></p>
<p>
由于docker的Ceph插件rexray对Ceph版本有一定的要求，当Ceph版本为hammer (0.94.10)时，rexray无法成功创建rbd设备。CentOS 7及以上版本，默认安装的就是hammer版本，因此，我们需要安装更高的jewel版本。Ceph的版本可参见。</p>
<p>
<span><strong>安装</strong></span></p>
<p>
为了安装速度，我们可以选用国内源。通常大家使用的国内源包括： </p>
<ul>
<li>
网易 http://mirrors.163.com/ceph</li>
<li>
中科大 http://mirrors.ustc.edu.cn/ceph</li>
<li>
阿里 http://mirrors.aliyun.com/ceph</li>
</ul>
<p>
<span><strong>添加源</strong></span></p>
<p>
给yum增加一个Ceph源(这里以网易源为例)。</p>
