centos7 ceph-deploy 安装jewel

一、安装依赖

以下操作需要在所有节点上执行
1、安装ceph源

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

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

[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

yum install ntp -y
systemctl enable ntpd
systemctl restart ntpd

4、创建部署用户

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

5、编辑/etc/hosts 添加ceph节点的主机名

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

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

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(仅需要配置admin节点)

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

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

mkdir my-cluster
cd my-cluster

2、清理旧配置，全新安装可不用执行

ceph-deploy purge node0 node1 node2 #此命令会删除ceph包，也就有执行此命令后，下面的命令才可执行
ceph-deploy purgedata node0 node1 node2
ceph-deploy forgetkeys

3、创建cluster

ceph-deploy new node0

4、编辑ceph.conf

[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

yum install ceph -y

6、添加 initial monitor

ceph-deploy mon create-initial

7、添加osd

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

四、安装radosgw

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