# 创建zonegroup
docker exec mon radosgw-admin zonegroup create --rgw-zonegroup=chian --endpoints=http://10.36.3.113:8080 --rgw-realm=earth --master –default
# 删除默认zone
docker exec mon radosgw-admin zone delete --rgw-zone=default
# 创建zone
docker exec mon radosgw-admin zone create --rgw-zonegroup=china --rgw-zone=huabei --master --default --endpoints=http://10.36.3.113:8080
