一、安装依赖

以下操作需要在所有节点上执行
1、安装ceph源

1	yum install epel-release yum-plugin-priorities -y

2、添加ceph源
编辑/etc/yum.repos.d/ceph.repo

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

[Ceph] name=Ceph packages for $basearch baseurl=http://debian.ustc.edu.cn/ceph/rpm-jewel/el7/$basearch enabled=1 gpgcheck=1 type=rpm-md gpgkey=http://debian.ustc.edu.cn/ceph/keys/release.asc priority=1 [Ceph-noarch] name=Ceph noarch packages baseurl=http://debian.ustc.edu.cn/ceph/rpm-jewel/el7/noarch enabled=1 gpgcheck=1 type=rpm-md gpgkey=http://debian.ustc.edu.cn/ceph/keys/release.asc priority=1 [ceph-source] name=Ceph source packages baseurl=http://debian.ustc.edu.cn/ceph/rpm-hammer/el7/SRPMS enabled=1 gpgcheck=1 type=rpm-md gpgkey=http://debian.ustc.edu.cn/ceph/keys/release.asc priority=1

3、安装ntp

1 2 3

yum install ntp -y systemctl enable ntpd systemctl restart ntpd

4、创建部署用户

1 2 3 4

useradd -m ceph passwd ceph echo "ceph ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/ceph chmod 0440 /etc/sudoers.d/ceph

5、修改sudo配置，找到Defaults   requiretty行修改如下

1	Defaults    !requiretty

6、编辑/etc/hosts 添加ceph节点的主机名

1 2 3

192.168.56.103 node0 192.168.56.104 node1 192.168.56.105 node2

二、配置部署节点
1、在部署节点上安装ceph-deploy

1	yum update && yum install ceph-deploy -y

2、配置部署节点的ceph用户，使用无密码方式以ceph用户登录ceph节点

1 2 3 4 5

su - ceph ssh-keygen ssh-copy-id ceph@node0 ssh-copy-id ceph@node1 ssh-copy-id ceph@node2

3、编辑 ceph用户下的文件 ~/.ssh/config

1 2 3 4 5 6 7 8 9

Host node0    Hostname node0    User ceph Host node1    Hostname node1    User ceph Host node2    Hostname node2    User ceph

4、修改~/.ssh/config 权限

1	chmod 644 ~/.ssh/config

三、部署ceph
以ceph用户登录布署节点
1、创建布署目录

1 2	mkdir my-cluster cd my-cluster

2、清理旧配置，全新安装可不用执行

1 2	ceph-deploy purgedata node0 node1 node2 ceph-deploy forgetkeys

3、创建cluster

1	ceph-deploy new node0

4、编辑ceph.conf

1 2 3 4 5 6 7 8 9 10 11

[global] fsid = 2e351760-f2f1-455f-940d-89be2f855a76 mon_initial_members = node0 mon_host = 192.168.56.103 auth_cluster_required = cephx auth_service_required = cephx auth_client_required = cephx osd pool default size = 1 osd pool default min size = 1 public network = 192.168.56.0/24 cluster network = 192.168.56.0/24

5、安装ceph
这里直接登录进各ceph节点，手动安装

1	yum install ceph -y

6、添加 initial monitor

1	ceph-deploy mon create-initial

7、添加osd

1 2	ceph-deploy osd prepare node0:sdb ceph-deploy osd activate  node0:/dev/sdb1

四、安装radosgw

1 2	ssh ceph@node0 sudo yum install ceph-radosgw -y ceph-deploy rgw create node0
