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
1
yum install epel-release yum-plugin-priorities -y
2、添加ceph源
编辑/etc/yum.repos.d/ceph.repo

priority=1
3、安装ntp

3
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
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

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

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

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

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 activatenode0:/dev/sdb1
四、安装radosgw
1
2
ssh ceph@node0 sudo yum install ceph-radosgw -y
ceph-deploy rgw create node0
