单节点ceph测试环境搭建

1.添加ceph.repo，安装ceph-deploy

[root@ss04 yum.repos.d]# cat /etc/yum.repos.d/ceph.repo
[Ceph]
name=Ceph packages for $basearch
baseurl=http://hk.ceph.com/rpm-jewel/el7/$basearch
enabled=1
gpgcheck=0

[Ceph-noarch]
name=Ceph noarch packages
baseurl=http://hk.ceph.com/rpm-jewel/el7/noarch
enabled=1
gpgcheck=0

[ceph-source]
name=Ceph source packages
baseurl=http://hk.ceph.com/rpm-jewel/el7/SRPMS
enabled=1
gpgcheck=0

# yum clean all
# yum install ceph-deploy

2.创建集群，并安装ceph相关软件包

# 创建目录
mkdir /home/ceph

# 进入目录，创建集群
cd /home/ceph
ceph-deploy new ss04

# 安装ceph软件包
yum install ceph ceph-radosgw

3.修改配置文件，配置初始化

[root@ss04 ceph]# cat ceph.conf
[global]
fsid = 90602ee8-b900-44f2-b218-9dd4fc8273af
mon_initial_members = ss04
mon_host = 10.64.37.54
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx

osd pool default size = 2
public network = 10.64.37.0/24

# 初始化
ceph-deploy mon create-initial

4.添加osd

# 创建文件夹
mkdir osd0 osd1
chown ceph:ceph osd0 osd1

# 添加osd
ceph-deploy osd prepare ss04:/home/ceph/osd0
ceph-deploy osd prepare ss04:/home/ceph/osd1

ceph-deploy osd activate ss04:/home/ceph/osd0
ceph-deploy osd activate ss04:/home/ceph/osd1
