# 配置文件存储

本小节仅需在主节点ceph1节点上执行。


#### 定义Ceph服务需求

1. 进入site.yml文件。
  1 2 cp /home/ceph-ansible/site.yml.sample /home/ceph-ansible/site.yml vim /home/ceph-ansible/site.yml

2. 如图所示，添加mdss选项：


#### 定义集群主机服务

在“ceph-ansible”目录内进入hosts文件。

```
vim /home/ceph-ansible/hosts
```

根据需要修改集群中各节点所拥有的应用：


#### 定义Ceph集群配置

1. 修改all.yml。
  1 vim /home/ceph-ansible/group_vars/all.yml

2. 通过查找 CephFS 关键字，修改配置如下。

  - Ceph在线下载方式：

    参数monitor_interface为Public Network的网口设备ID。

  - Ceph离线下载方式：
    1 2 3 ceph_origin: distro ceph_repository: local ceph_stable_release: nautilus


#### 定义OSD

参照定义OSD的方法，定义相应的OSD。
