配置对象存储

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. 在“hosts”选项下，增加rgws的定义。

   1 2 3 4 5 6 7 8 9 10 11 12 13

   - hosts: - mons - osds # - mdss - rgws # - nfss # - rbdmirrors - clients - mgrs # - iscsigws # - iscsi-gws # for backward compatibility only! # - grafana-server # - rgwloadbalancers

vim /home/ceph-ansible/group_vars/all.yml

在all.yml中，设置前端网络类型，端口，每个RGW节点的RGW实例数。

• Ceph在线下载方式：

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

  ceph_origin: repository ceph_repository: community ceph_mirror: http://download.ceph.com ceph_stable_release: nautilus ceph_stable_repo: "{{ ceph_mirror }}/rpm-{{ ceph_stable_release }}" ceph_stable_redhat_distro: el7 monitor_interface: enp133s0 journal_size: 5120 public_network: 172.19.106.0/0 cluster_network: 172.19.106.0/0 osd_objectstore: bluestore ## Rados Gateway options radosgw_frontend_type: beast radosgw_frontend_port: 12345 radosgw_interface: "{{monitor_interface}}" radosgw_num_instances: 3

  部分参数填写说明如表1所示。

  表1 参数填写说明

  参数	说明
  monitor_interface	Public Network的网口设备ID
  radosgw_frontend_type	RGW前端类型，根据需要选填
  radosgw_frontend_port	RGW前端端口，根据需要选填
  radosgw_num_instances	设置每个节点上RGW的实例个数，此时RGW的访问端口基于radosgw_frontend_port指定的端口号递增
