Ceph单节点安装

此处使用的是 Ubuntu16.04 KVM 虚拟机.

（1）更换软件源

cp /etc/apt/sources.list /etc/apt/sources.list.bak

/etc/apt/sources.list：

deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse

sudo apt-get update && sudo apt-get upgrade

（2）主机名解析

编辑 /etc/hosts：

...
192.168.122.124 

为此处的主机名。

（3）安装 ceph-deloy

wget -q -O- 'https://download.ceph.com/keys/release.asc' | sudo apt-key add -
echo deb https://download.ceph.com/debian-nautilus/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
sudo apt-get update
sudo sudo apt-get install ceph-deploy

ceph 版本：https://download.ceph.com/

（4）部署 monitor

mkdir ceph-cluster && cd ceph-cluster
sudo ceph-deploy new 
sudo ceph-deploy install 
sudo ceph-deploy mon create-initial

sudo ceph-deploy admin  
sudo chmod +r /etc/ceph/ceph.client.admin.keyring
ceph config set mon auth_allow_insecure_global_id_reclaim false

（5）部署 manager

sudo ceph-deploy mgr create 

（6）部署 OSD
此处 主机上有 /dev/vdb、/dev/vdc 和 /dev/vdd 三块硬盘。

sudo ceph-deploy disk zap  /dev/vdb
sudo ceph-deploy disk zap  /dev/vdc
sudo ceph-deploy disk zap  /dev/vdd

sudo ceph-deploy osd create  --data /dev/vdb
sudo ceph-deploy osd create  --data /dev/vdc
sudo ceph-deploy osd create  --data /dev/vdd

（7）部署 radosgw

sudo apt-get install radosgw
sudo ceph-deploy rgw create 

（8）查看集群状态

$ ceph -s
