FastDFS—基础

一、分布式文件系统

　　1、什么是分布式文件系统

　　　　随着文件数据的越来越多，通过tomcat或nginx虚拟化的静态资源文件在单一的一个服务器节点内是存不下的，如果用多个节点来存储也可以，但是不利于管理和维护，所以我们需要一个系统来管理多台计算机节点上的文件数据，这就是分布式文件系统。

　　　　分布式文件系统是一个允许文件通过网络在多台节点上分享的文件系统，多台计算机节点共同组成一个整体，为更多的用户提供分享文件和存储空间。比如常见的网盘，本质就是一个分布式的文件存储系统。虽然我们是一个分布式的文件系统，但是对用户来说是透明的，用户使用的时候，就像是访问本地磁盘一样。

　　　　分布式文件系统可以提供冗余备份，所以容错能力很高。系统中有某些节点宕机，但是整体文件服务不会停止，还是能够为用户提供服务，整体还是运作的,数据也不会丢失。

　　　　分布式文件系统的可扩展性强，增加或减少节点都很简单，不会影响线上服务，增加完毕后会发布到线上，加入到集群中为用户提供服务。

　　　　分布式文件系统可以提供负载均衡能力，在读取文件副本的时候可以由多个节点共同提供服务，而且可以通过横向扩展来确保性能的提升与负载。

二、fastDFS介绍

　　1、简介

　　FastDFS 是一个开源的高性能分布式文件系统（DFS）。它的主要功能包括：文件存储，文件同步和文件访问，以及高容量和负载平衡。主要解决了海量数据存储问题，特别适合以中小文件（建议范围：4KB < file_size <500MB）为载体的在线服务。

FastDFS 系统有三个角色：跟踪服务器(Tracker Server)、存储服务器(Storage Server)和客户端(Client)。

　　Tracker Server：跟踪服务器，主要做调度工作，起到均衡的作用；负责管理所有的 storage server和 group，每个 storage 在启动后会连接 Tracker，告知自己所属 group 等信息，并保持周期性心跳。

　　Storage Server：存储服务器，主要提供容量和备份服务；以 group 为单位，每个 group 内可以有多台 storage server，数据互为备份。

　　Client：客户端，上传下载数据的服务器，也就是我们自己的项目所部署在的服务器。

　　2、fastDFS 存储策略

　　为了支持大容量，存储节点（服务器）采用了分卷（或分组）的组织方式。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。

　　3、fastDFS 上传过程

　　FastDFS向使用者提供基本文件访问接口，比如upload、download、append、delete等，以客户端库的方式提供给用户使用。
　　Storage Server会定期的向Tracker Server发送自己的存储信息。当Tracker Server Cluster中的Tracker Server不止一个时，各个Tracker之间的关系是对等的，所以客户端上传时可以选择任意一个Tracker。
当Tracker收到客户端上传文件的请求时，会为该文件分配一个可以存储文件的group，当选定了group后就要决定给客户端分配group中的哪一个storage server。当分配好storage server后，客户端向storage发送写文件请求，storage将会为文件分配一个数据存储目录。然后为文件分配一个fileid，最后根据以上的信息生成文件名存储文件。

　　4、fastDFS 文件下载

　　客户端uploadfile成功后，会拿到一个storage生成的文件名，接下来客户端根据这个文件名即可访问到该文件。

　　跟upload file一样，在downloadfile时客户端可以选择任意tracker server。tracker发送download请求给某个tracker，必须带上文件名信息，tracke从文件名中解析出文件的group、大小、创建时间等信息，然后为该请求选择一个storage用来服务读请求。

三、安装 fastDFS 环境

　　1、下载安装 libfastcommon，并解压

wget https://github.com/happyfish100/libfastcommon/archive/V1.0.7.tar.gz

　　　　进入到 libfastcommon-1.0.7 中

　　　　编译、安装

　　　　创建软连接

ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so
ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so
ln -s /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so

　　2、安装 fastDFS

wget https://github.com/happyfish100/fastdfs/archive/V5.05.tar.gz

　　　　解压

 tar -zxvf V5.05.tar.gz 
 cd cd fastdfs-5.05/

　　　　编译安装

./make.sh
./make.sh install

　　　　进入 /usr/bin，全是脚本文件

　　　　进入 /etc/fdfs/，配置文件

　　　　进入 /etc/init.d，服务脚本文件

　　　　fastDFS 服务脚本设置的 bin 目录是 /usr/local/bin，但实际命令安装在 /usr/bin/ 下。

　　　　建立 /usr/bin 到 /usr/local/bin 的软连接

 ln -s /usr/bin/fdfs_trackerd   /usr/local/bin
 ln -s /usr/bin/fdfs_storaged   /usr/local/bin
 ln -s /usr/bin/stop.sh         /usr/local/bin
 ln -s /usr/bin/restart.sh      /usr/local/bin

# check storage HTTP server alive uri/url
# NOTE: storage embed HTTP server support uri: /status.html
http.check_alive_uri=/status.html

　创建目录（-p递归创建）

mkdir /usr/local/fastdfs/tracker -p

　　4、启动 Tracker

# 第一种
    /etc/init.d/fdfs_trackerd start
# 也可以用这种方式启动，前提是上面创建了软链接，后面都用这种方式
    service fdfs_trackerd start

　　　　Tracker服务启动成功后，会在base_path下创建data、logs两个目录。目录结构如下：

${base_path}
  |__data
  |   |__storage_groups.dat：存储分组信息
  |   |__storage_servers.dat：存储服务器列表
  |__logs
  |   |__trackerd.log： tracker server 日志文件

　　5、关闭 Tracker 命令

 service fdfs_trackerd stop

　　6、设置 Tracker 开机启动

chkconfig fdfs_trackerd on

　　　　或者，前提需要添加权限

chmod +x /etc/rc.d/rc.local

vim /etc/rc.d/rc.local

# 加入配置：
/etc/init.d/fdfs_trackerd start

五、配置 FastDFS 存储 (Storage)

　　2、启动 Storage

　　　　启动Storage前确保Tracker是启动的。

　　　初次启动 Storage 会在刚才设置的目录下创建 data 、logs 两个目录。

# 可以用这种方式启动
/etc/init.d/fdfs_storaged start

# 第二种
service fdfs_storaged start

　　3、关闭 Storage 命令

service fdfs_storaged stop

　　4、查看 Storage 和 Tracker 是否在通信

/usr/bin/fdfs_monitor /etc/fdfs/storage.conf

　　5、设置 Storage 开机启动

chkconfig fdfs_storage on

　　　　或者修改配置文件

vim /etc/rc.d/rc.local

# 加入配置
/etc/init.d/fdfs_storaged start

　　6、Storage 目录

　　7、文件上传测试

　　修改 Tracker 服务器的客户端配置文件，并且创建

# connect timeout in seconds
# default value is 30s
connect_timeout=30

# network timeout in seconds
# default value is 30s
network_timeout=60

# the base path to store log files

# since V4.05
storage_ids_filename = storage_ids.conf


#HTTP settings
http.tracker_server_port=80

#use "#include" directive to include HTTP other settiongs
##include http.conf

　　创建文件夹

mkdir /usr/local/fastdfs/client

　　随便照一张图片下载下来，并重命名

# 使用命令，前面脚本，客户端，要上传的文件
