[原]fastdfs 新添加一个项目的图片目录 实现独立的上传下载功能
1，功能需求
Fastdfs已经安装完成，部署过程见：http://blog.csdn.net/mchdba/article/details/50933405，fastdfs安装启动后，默认只有一个group1，只能适合用于一个项目；那么如果有新项目过来了，是否需要再准备新的linux服务器重新安装一套fastdfs呢？答案是否定的
这里已经实现了group1/group2/group3，现在有新的项目过来，不想重新搭建安装fastdfs环境，想直接在这上面再添加一个项目图片目录group4，存储位置要分开，实现正常上传下载访问功能。我们可以在原来的fastdfs上新添加一个group4来实现这个新的项目的图片目录的功能，这省了服务器资源也节省了部署时间。
操作思路是：在mod_fastdfs.conf上添加新的group组，然后准备新的storage_group4.conf文件，再启动一个fdfs_storaged进程。
2，配置mod_fastdfs.conf文件
# 创建新的group文件夹 mkdir /file/fastdfs_group4 chown –R
vim /etc/fdfs/mod_fastdfs.conf # runing for haisheng，在这里添加一个新的group [group4] group_name=group4 storage_server_port=23004 store_path_count=1 store_path0=/file/fastdfs_group4 |
3，在nginx配置group4
# for wenhaisheng on 20160617 location /group4/M00 { root /file/fastdfs_group4/data; include gzip.conf; ngx_fastdfs_module; client_max_body_size 100m; expires 12h; } |
4，启动新的fastdfs服务
启动命令比较方便，加上新的group4配置文件即可：
# 开始启动 [root@test_dev_fastdfs_32 ~]# /usr/local/bin/fdfs_storaged /etc/fdfs/storage_group4.conf [root@test_dev_fastdfs_32 ~]#
# 查看fdfs进程，已经有了group4的storaged进程 [root@test_dev_fastdfs_32 ~]# ps -eaf|grep fastdfs |grep conf fastdfs 3023 1 0 Jun17 ? 00:00:05 /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf fastdfs 10851 1 0 Jun08 ? 00:00:42 /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf fastdfs 10867 1 0 Jun08 ? 00:00:37 /usr/local/bin/fdfs_storaged /etc/fdfs/storage_group2.conf fastdfs 10891 1 0 Jun08 ? 00:00:36 /usr/local/bin/fdfs_storaged /etc/fdfs/storage_group3.conf fastdfs 31820 1 0 Jun17 ? 00:00:03 /usr/local/bin/fdfs_storaged /etc/fdfs/storage_group4.conf [root@test_dev_fastdfs_32 ~]# |
5，测试功能
使用fdfs_test命令上传文件：
[fastdfs@test_dev_fastdfs_32 fdfs]$ /usr/local/bin/fdfs_test /etc/fdfs/client.conf upload /tmp/xg.png This is FastDFS client test program v4.06

这里fdfs_test组件默认是上传到group1上面去，那如何测试group4的功能，可以将/group1/M00/00/23/wKh5IFdjrumAc879AASrW0_jx78607_big.png copy到group4里面的对应目录去，然后把网址中的group1换成group4，新网址变成：
http://192.168.121.32/group4/M00/00/23/wKh5IFdjrumAc879AASrW0_jx78607_big.png
这样先证明了这个fastdfs的group4新目录里面的图片是可以被访问的，然后再让开发人员在调用组件上传突破的时候，将调用url里面的group1变成group4即可。
