fastdfs-client-java fastdfs5.0.4上传、下载、删除
一、在&下载客户端，解压后并执行ant命令，在E:\tools\libs\fastdfs\fastdfs-client-java-master\src\build下会生成fastdfs_client.jar如图示
二、mvn安装fastdfs_client.jar，在cmd中执行命令
mvn install:install-file -DgroupId=org.csource -DartifactId=fastdfs-client-java -Dversion=5.0.4 -Dpackaging=jar -Dfile=D:\fastdfs_client.jar&
三、在eclipse中新建maven项目fastdfs-demo，在pom.xml中加入依赖如下
&project&xmlns="http://maven.apache.org/POM/4.0.0"&xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

在src/main/resources中新建fdfs_client.conf文件，内容如下

http.tracker_http_port = 80
http.anti_steal_token = no
http.secret_key = FastDFS
tracker_server = 192.168.17.112:22122
#tracker_server = 192.168.0.119:22122
在src/main/java中创建TestFastDfs.java如下

【rom】小米4原生安卓5.0.2包放出了赶紧的下载
编辑：chen
来源：网络
开发者@秋叶随风ivan已经完成了原生Android 5.0.2系统的小米3与小米4的适配，喜欢原生风格的机友们不妨考虑一下。由于硬件平台大体相同，因此该ROM支持小米手机3联通/电信版、小米手机4联通3G/电信3G版以及小米手机4移动/联通4G版。
刷机包：【】（密码：l8pn）
Recovery：【】（密码：r0t7）
目前该ROM还存在两个比较明显的Bug，其一是多用户功能使用之后文件管理器会FC，另外就是通话中灭屏状态下触摸屏可操作。

由于网站使用nfs共享方式保存用户上传的图片，附件等资料，然后通过apache下载的方式供用户访问，在网站架构初期，使用这种简单的方式实现了静态资源的读写分离，但随着网站数据量的增加，图片服务器渐渐成为整个网站的短板，缘次催生了使用fastfds的想法，故而先进行一番简单的测试！在开始之前还是先来看看fastfds的介绍信息：
FastDFS is an open source high performance distributed file system (DFS). It's major functions include: file storing, file syncing and file accessing, and design for high capacity and load balancing.
FastDFS is an open source high performance distributed file system. It's major functions include: file storing, file syncing and file accessing (file uploading and file downloading), and it can resolve the high capacity and load balancing problem. FastDFS should meet the requirement of the website whose service based on files such as photo sharing site and vidio sharing site.
FastDFS has two roles: tracker and storage. The tracker takes charge of scheduling and load balancing for file access. The storage store files and it's function is file management including: file storing, file syncing, providing file access interface. It also manage the meta data which are attributes representing as key value pair of the file. For example: width=1024, the key is &width& and the value is &1024&.
The tracker and storage contain one or more servers. The servers in the tracker or storage cluster can be added to or removed from the cluster by any time without affecting the online services. The servers in the tracker cluster are peer to peer.
The storarge servers organizing by the file volume/group to obtain high capacity. The storage system contains one or more volumes whose files are independent among these volumes. The capacity of the whole storage system equals to the sum of all volumes' capacity. A file volume contains one or more storage servers whose files are same among these servers. The servers in a file volume backup each other, and all these servers are load balancing. When adding a storage server to a volume, files already existing in this volume are replicated to this new server automatically, and when this replication done, system will switch this server online to providing storage services. When the whole storage capacity is insufficiency, you can add one or more volumes to expand the storage capacity. To do this, you need to add one or more storage servers.
The identification of a file is composed of two parts: the volume name and the file name.
fastdfs是一个开源的，高性能的的分布式文件系统，他主要的功能包括：文件存储，同步和访问，设计基于高可用和负载均衡，fastfd非常适用于基于文件服务的站点，例如图片分享和视频分享网站
fastfds有两个角色：跟踪服务和存储服务，跟踪服务控制，调度文件以负载均衡的方式访问；存储服务包括：文件存储，文件同步，提供文件访问接口，同时以key value的方式管理文件的元数据
跟踪和存储服务可以由1台或者多台服务器组成，同时可以动态的添加，删除跟踪和存储服务而不会对在线的服务产生影响，在集群中，tracker服务是对等的
存储系统由一个或多个卷组成，卷与卷之间的文件是相互独立的，所有卷的文件容量累加就是整个存储系统中的文件容量。一个卷可以由一台或多台存储服务器组成，一个卷下的存储服务器中的文件都是相同的，卷中的多台存储服务器起到了冗余备份和负载均衡的作用。在卷中增加服务器时，同步已有的文件由系统自动完成，同步完成后，系统自动将新增服务器切换到线上提供服务。当存储空间不足或即将耗尽时，可以动态添加卷。只需要增加一台或多台服务器，并将它们配置为一个新的卷，这样就扩大了存储系统的容量。
下面几张图可以清楚的说明fastfds的架构和文件上传和下载流程等：
下面将介绍下fastdfs在rhel上的部署过程

[root@db1&~]#&wget&/downloads/libevent/libevent/libevent-2.0.14 &-stable.tar.gz &[root@db1&~]#&tar&-zxvpf&libevent-2.0.14-stable.tar.gz& &[root@db1&~]#&cd&libevent-2.0.14-stable &[root@db1&libevent-2.0.14-stable]#&./configure&--prefix=/usr/local/libevent-2.0.14&&&& &make&&&&make&install &[root@db1&~]#&wget&/files/FastDFS_v3.02.tar.gz &[root@db1&~]#&tar&-zxvf&FastDFS_v3.02.tar.gz& &[root@db1&~]#&cd&FastDFS &[root@db1&FastDFS]#&grep&-A&4&'/usr/local/FastDFS'&make.sh& &TARGET_PREFIX=/usr/local/FastDFS &TARGET_CONF_PATH=/etc/fdfs &WITH_HTTPD=1&WITH_LINUX_SERVICE=1&[root@db1&FastDFS]#&./make.sh&C_INCLUDE_PATH=/usr/local/libevent-2.0.14/include&& &LIBRARY_PATH=/usr/local/libevent-2.0.14/lib &[root@db1&FastDFS]#&./make.sh&install &[root@db1&FastDFS]#&ls&/etc/fdfs/ &client.conf&&http.conf&&mime.types&&storage.conf&&tracker.conf&
二：tracker配置文件
[root@db1&~]#&grep&-v&'^#'&/etc/fdfs/tracker.conf&|grep&-v&'^$' &disabled=false&bind_addr=192.168.123.110 &port=22122&connect_timeout=30&network_timeout=60&base_path=/home/data/fastdfs &max_connections=256&work_threads=4&store_lookup=2&store_group=group2&store_server=0&store_path=0&download_server=0&reserved_storage_space&=&4GB&log_level=info&run_by_group= &run_by_user= &allow_hosts=* &sync_log_buff_interval&=&10&check_active_interval&=&120&thread_stack_size&=&64KB&storage_ip_changed_auto_adjust&=&true&storage_sync_file_max_delay&=&86400&storage_sync_file_max_time&=&300&use_trunk_file&=&false& &slot_min_size&=&256&slot_max_size&=&16MB&trunk_file_size&=&64MB&http.disabled=false&http.server_port=8080&http.check_alive_interval=30&http.check_alive_type=tcp&http.check_alive_uri=/status.html &http.need_find_content_type=true&&[root@db1&~]#&grep&-v&'^#'&/etc/fdfs/http.conf&&|grep&-v&'^$' &http.default_content_type&=&application/octet-stream &http.mime_types_filename=/etc/fdfs/mime.types &http.anti_steal.check_token=false&http.anti_steal.token_ttl=900&http.anti_steal.secret_key=FastDFS&http.anti_steal.token_check_fail=/home/data/fastdfs/conf/anti-steal.jpg&
三：启动tracker服务，需要注意tracker.conf文件最后一行为#include httpd.conf

五：启动storage，需要注意storage.conf文件最后一行为#include httpd.conf
[root@db2&~]#&mkdir&-p&/home/data/fastdfs &[root@db2&~]#&echo&'/usr/local/libevent-2.0.14/include/'&&/etc/ld.so.conf &[root@db2&~]#&echo&'/usr/local/libevent-2.0.14/lib/'&&/etc/ld.so.conf &[root@db2&~]#&ldconfig &&[root@db2&~]#&tail&-2&/etc/fdfs/storage.conf& &#use&&#include&&directive&to&include&HTTP&other&settings &#include&http.conf &&[root@db2&~]#&/usr/local/FastFDS/bin/fdfs_storaged&/etc/fdfs/storage.conf& &mkdir&data&path:&00&... &mkdir&data&path:&01&... &mkdir&data&path:&02&... &&&&输出省略&&&& &data&path:&/home/data/fastdfs/data,&mkdir&sub&dir&done. &&[root@db2&~]#&ps&-ef&|grep&fdfs &root&&&&&14451&&&&&1&&0&16:15&?&&&&&&&&00:00:00&/usr/local/FastFDS/bin/fdfs_storaged& &/etc/fdfs/storage.conf &root&&&&&1&&0&16:16&pts/1&&&&00:00:00&grep&fdfs &&[root@db2&~]#&netstat&-ntpl&|grep&fdfs &tcp&&&&&&&&0&&&&&&0&192.168.123.20:8888&&&&&&&&&0.0.0.0:*&&&&&&&&&&&&&&&&&&&LISTEN&&&&&& &14451/fdfs_storaged& &tcp&&&&&&&&0&&&&&&0&192.168.123.20:23000&&&&&&&&0.0.0.0:*&&&&&&&&&&&&&&&&&&&LISTEN&&&&&& &14451/fdfs_storaged&&
