1. 修改自定义storage id文件
若使用了storage_ids.conf，则需要修改所有的storeage、tracker的storage_ids.conf。
2. 修改nginx_http_module模块配置文件
在所有storage机器上，修改/etc/fdfs/mod_fastdfs.conf，
group_name=group1/group2/group3 # 所有组名group_count = 3 # 组的总数# 把所有组和目录都添加上[group1]group_name=group1storage_server_port=23000store_path_count=3store_path0=/opt/fastdfs/data/group1/M00store_path1=/opt/fastdfs/data/group1/M01store_path2=/opt/fastdfs/data/group1/M02# group settings for group #2# since v1.14# when support multi-group, uncomment following section as neccessary[group2]group_name=group2storage_server_port=23000store_path_count=3store_path0=/opt/fastdfs/data/group2/M00store_path1=/opt/fastdfs/data/group2/M01store_path2=/opt/fastdfs/data/group2/M02[group3]group_name=group3storage_server_port=23000store_path_count=3store_path0=/opt/fastdfs/data/group3/M00store_path1=/opt/fastdfs/data/group3/M01store_path2=/opt/fastdfs/data/group3/M02
