Ceph集群安装
1.环境说明2. 安装步骤2.1 ceph模块安装（各节点都需要安装）yum installceph-deploy ceph python-ceph nodejs-argparse redhat-lsb xfsdump qemu-kvmqemu-kvm-tools qemu-img qemu-guest-agent libvirt –y
2.2 生成fsid# uuidgen
2.3 ceph配置（在bgw-os-node151上执行）# cat > /etc/ceph/ceph.conf << EOF

2.4 在bgw-os-node151上创建各种密钥# ceph-authtool --create-keyring /etc/ceph/ceph.mon.keyring--gen-key -n mon. --cap mon 'allow *'

3.添加元数据服务器3.1在bgw-os-node151上创建mds# mkdir -p /var/lib/ceph/mds/ceph-bgw-os-node151
# ceph-authtool --create-keyring/var/lib/ceph/bootstrap-mds/ceph.keyring --gen-key -n client.bootstrap-mds #集群中仅需要执行一次

4.添加rules在bgw-os-node151上执行如下命令：
# ceph osd crush rule create-simplejiayuan-replicated-ruleset default rack
# ceph osd pool set data crush_ruleset 1
# ceph osd pool set metadata crush_ruleset 1
# ceph osd pool set rbd crush_ruleset 1
# ceph osd pool set images crush_ruleset 1
# ceph osd pool set volumes crush_ruleset 1
# ceph osd pool set compute crush_ruleset 1
