ceph安装过程
准备三个节点ceph-1、ceph-2、ceph-3配置host
cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.53 ceph-3
10.0.0.52 ceph-2
10.0.0.51 ceph-1 /etc/ceph/ceph.conf中加入
public network = 10.0.0.0/24 在ceph-1上做无密码登录配置
然后在ceph-1上安装ceph-deploy
yum install ceph-deploy 在ceph-1上使用ceph-deploy安装ceph
mkdir my-cluster
cd my-cluster
ceph-deploy new ceph-1
ceph-deploy install ceph-1 ceph-2 ceph-3 --repo-url=http://mirrors.aliyun.com/ceph/rpm-luminous/el7/ 创建第一个ceph monitor
ceph-deploy mon create-initial 添加一个metadata服务
ceph-deploy mds create ceph-1-51 配置更改后同步到远程节点
ceph-deploy --overwrite-conf config pushceph-3-53ceph-2-52ceph-deploy mgr create ceph-2-52 ceph-3-53 ceph health问题解决
# ceph -s
cluster:
id: 7af4a47d-2cbf-4a8a-b156-f0d3f908f137
health: HEALTH_WARN
clock skew detected on mon.ceph-2-52, mon.ceph-3-53通过ceph health detail发现这是因为时间不同步造成的，做过ntp同步后解决
# ceph -s
cluster:
id: 7af4a47d-2cbf-4a8a-b156-f0d3f908f137
health: HEALTH_OK
