ceph学习笔记

环境centos6.6
安装参考
http://ceph.com/docs/master/install/install-storage-cluster/
不过yum配置要改
yum install yum-plugin-priorities
vim /etc/yum/pluginconf.d/priorities.conf

[main]
enabled = 1

ensure your YUM ceph.repo entry includes priority=2. See Get Packages for details:

[code="java"]
# cat ceph.repo
[ceph]
name=Ceph packages for $basearch
#baseurl=http://ceph.com/rpm-{ceph-release}/{distro}/$basearch
baseurl=http://ceph.com/rpm-emperor/el6/$basearch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-noarch]
name=Ceph noarch packages
#baseurl=http://ceph.com/rpm-{ceph-release}/{distro}/noarch
baseurl=http://ceph.com/rpm-emperor/el6/noarch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-source]
name=Ceph source packages
#baseurl=http://ceph.com/rpm-{ceph-release}/{distro}/SRPMS
baseurl=http://ceph.com/rpm-emperor/el6/SRPMS
enabled=0

注意上面几个变量替换掉了，如果出现找不到的情况

yum install snappy leveldb gdisk python-argparse gperftools-libs
