一、 安装tracker_server
1、安装libevent
卸载原有的linevent
yum -y remove libevent
wget http://down1.chinaunix.net/distfiles/libevent-1.4.12-stable.tar.gz
tar xvf libevent1.4.12-stable.tar.gz
cd libevent
./configure -prefix=/usr
make
make install
2、安装tracker_server
wget http://fastdfs.googlecode.com/files/FastDFS_v3.11.tar.gz
tar xvzf FastDFS_v3.05.tar.gz
cd FastDFS
./make.sh
./make.sh install
nginx添加fastdfs模块，所以不需要fastdfs支持 http 所以我就不需要去掉 #WITH_HTTPD=1 前的注释了，直接编译./make.sh
vi /etc/fdfs/tracker.conf
修改/etc/fdfs/tracker.conf，主要修改以下两处，如有其他调整，可参考文档自行调整，默认的配置也可以工作。
# the base path to store data and log files
base_path=/home/tracker ====> 放置data和log的目录
#func：上传文件的选组方式。
#valu：0、1或2。
# 0：表示轮询
# 1：表示指定组
# 2：表示存储负载均衡（选择剩余空间最大的组）
store_lookup=0（默认配置为2）一般配置0测试为0
3、启动tracker服务
mkdir -p /home/tracker
启动tracker服务
[root@tracker]# /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
确认8080,22122端口已经监听
[root@tracker]# netstat -nl|grep -E '8080|22122'
tcp 0 0 0.0.0.0:22122 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN
V4.02办法默认开机启动
启动时报错：
处理方式：
原因是系统debug的路径中没有我们实际的动态库的路径
ln -s /usr/lib/libevent-1.4.so.2 /usr/lib64/libevent-1.4.so.2
停止tracker服务
[root@tracker]# /usr/local/bin/stop.sh /etc/fdfs/tracker.conf
进入/home/tracker /logs/tracker.log查看tracker的日志是否正常启动
二、 安装storage_server
1、安装FastDFS
wget http://fastdfs.googlecode.com/files/FastDFS_v3.11.tar.gz
wget http://fastdfs.googlecode.com/files/fastdfs-nginx-module_v1.10.tar.gz
wget http://nginx.org/download/nginx-1.0.11.tar.gz
wget http://down1.chinaunix.net/distfiles/libevent-1.4.12-stable.tar.gz
卸载原有的linevent
tar xvf libevent1.4.12-stable.tar.gz（未安装时安装）
cd libevent1.4.12-stable
./configure -prefix=/usr
Make
Make install
tar xvzf FastDFS_v3.05.tar.gz
cd FastDFS
./make.sh
./make.sh install
2、安装Nginx
groupadd www 建立用户组
useradd -g www www 建立用户www属于www用户组的
tar xvzf nginx-1.0.11.tar.gz
tar xvzf fastdfs-nginx-module_v1.10.tar.gz
cd nginx-1.0.11
./configure --prefix=/usr/local/nginx --add-module=/root/fastdfs-nginx-module/src
./configure --user=www --group=www --add-module=../fastdfs-nginx-module/src
--prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make
make install
3、配置storage_server
vi /etc/fdfs/storage.conf
修改/etc/fdfs/storage.conf，主要修改以下几处，如有其他调整，可参考文档自行调整，默认的配置也可以工作。
# the name of the group this storage server belongs to
group_name=group1 ====> 此台storage server所属的服务器组名
# the base path to store data and log files
base_path=/home/storage ====> 放置data和log的目录
# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
store_path0=/home/storage ====> 放置文件的目录
# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=172.16.23.176:22122 ====> tracker server的ip和端口，此处可以写多个tracker server，每行一个
#HTTP settings
http.disabled=true ====> 关闭内置的web server
# the port of the web server on this storage server
http.server_port=80 ====> web server的端口改成80
扩展模块配置
cp /root/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
vi /etc/fdfs/mod_fastdfs.conf
# the base path to store log files
base_path=/home/storage ====> 放置log的目录
# FastDFS tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=172.16.23.176:22122 ====> tracker server的ip和端口，此处可以写多个tracker server，每行一个
# the group name of storage server
group_name=group1 ====> 此台storage server所属的服务器组名
# if uri including group name
# default value is false
url_have_group_name =true ====> 在URL中包含group名称
# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
store_path0=/home/storage ====> 放置文件的目录
# if need find content type from file extension name
# should set to false because it done by apache
http. need_find_content_type=true====> nginx下需要将http.conf中的参数http. need_find_content_type设置为true，apache设置为false（文档建议，个人测试中未设置）
启动storage_server
mkdir -p /home/storage
mkdir -p /home/storage/data
在nginx的server配置段中增加M00的location声明
[root@storage]# vi /usr/local/nginx/conf/nginx.conf
location /group1/M00 {
root /home/storage/data;
ngx_fastdfs_module;
}
设置其它组：
location /group2/M00 {
root /home/storage/data;
ngx_fastdfs_module;
}
不建议做组间跳转或者proxy，建议每个group采用一个子域名，即通过子域名来区分group。如：g1.xxx.com, g2.xxx.com等等。
创建M00目录的软连接(可忽略不配)
[root@storage]# ln -s /home/storage/data /home/storage/data/M00
启动storage服务
/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf
启动nginx
[root@tracker]# /usr/local/nginx/sbin/nginx
确认80, 23000端口已经监听
[root@storage]# netstat -nl|grep -E '80|23000'
tcp 0 0 0.0.0.0:23000 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
重启storage服务：
/usr/local/bin/restart.sh /etc/fdfs/storage.conf
停止storage服务：
/usr/local/bin/stop.sh /etc/fdfs/storage.conf
开机启动服务：
vi /etc/rc.local
/usr/local/nginx/sbin/nginx
/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf
3、查看组中运行多个storage_server
进入tracker_server /home/tracker/data
cat storage_servers_new.dat
4、测试上传文件（tracker_server端操作）
FastDFS有自带的客户端程序，经过配置后，可进行文件上传。
vi /etc/fdfs/client.conf文件。
Base_path=/tmp
修改tracker_server, 可以不是唯一
Tracker_server 172.16.23.176:22122
开启http支持
##include http.conf –>#include http.conf
[root@localhost ~]# vi b.txt
/usr/local/bin/fdfs_test /etc/fdfs/client.conf upload b.txt
测试上传(常用客户上传)
/usr/local/bin/fdfs_upload_file /etc/fdfs/client.conf b.txt
浏览
http://172.16.23.176:8080/group1/M00/00/00/rBAXr1AJGF_3rC-ZAAAAEc45MdM850_big.txt
跳转至以下地址
http://172.16.23.173/group1/M00/00/00/rBAXr1AJGF_3rC-ZAAAAEc45MdM850_big.txt
http://172.16.23.175/group1/M00/00/00/rBAXr1AJGF_3rC-ZAAAAEc45MdM850_big.txt
查看存储内文件：
cd /home/storage/data/M00/M00/00/00
storang1内容
Storang2内容
cd /home/storage/data/M00/M00/00/00
三、文件操作
1、查看文件信息（tracker_server端操作）
fdfs_file_info /etc/fdfs/client.conf group1/M00/00/00/rBAXr1AIMnnK94hVAAAAFPmPj8E816.txt
2、下载文件（tracker_server端操作）
/usr/local/bin/fdfs_download_file /etc/fdfs/client.confgroup1/M00/00/00/rBAXr1AIMnnK94hVAAAAFPmPj8E816.txt
下载后文件名更改为demofile.txt
3、文件删除（tracker_server端操作）
/usr/local/bin/fdfs_delete_file /etc/fdfs/client.conf group1/M00/00/00/rBAXr1AIMnnK94hVAAAAFPmPj8E816.txt
四、 服务器信息
1、存储服务器信息查看（tracker_server端操作）
/usr/local/bin/fdfs_monitor /etc/fdfs/client.conf -h 172.16.23.176 list
/usr/local/bin/fdfs_monitor /etc/fdfs/client.conf
2、 存储服务器踢出集群（tracker_server端操作）
/usr/local/bin/fdfs_monitor /etc/fdfs/client.conf -h 172.16.23.176 delete group1 172.16.23.173
注意：如果被删除的storage server的状态是ACTIVE，也就是该storage server还在线上服务的情况下，是无法删除掉的。
3、 存储服务器状态
storage server有7个状态，如下：
# FDFS_STORAGE_STATUS_INIT :初始化，尚未得到同步已有数据的源服务器
# FDFS_STORAGE_STATUS_WAIT_SYNC :等待同步，已得到同步已有数据的源服务器
# FDFS_STORAGE_STATUS_SYNCING :同步中
# FDFS_STORAGE_STATUS_DELETED :已删除，该服务器从本组中摘除（注：本状态的功能尚未实现）
# FDFS_STORAGE_STATUS_OFFLINE :离线
# FDFS_STORAGE_STATUS_ONLINE :在线，尚不能提供服务
# FDFS_STORAGE_STATUS_ACTIVE :在线，可以提供服务
五、 扩展
1、扩展到多台tracker和storage的配置方法
2、按照步骤一配置所需数量的tracker，只需要ip地址不重复就可以。
3、按照步骤二配置所需数量的storage,注意Group_name项，如果是同一组，那么group_name相同，端口号也相同，如果group_name不同，那么端口号也不同。
4、在storage的配置文件中修改tracker_server的地址和端口，可以指定多个，将新增的tracker也加进去就可以了。
原始文件名和FastDFS上的文件名对应关系都是保存在DB, 源文件只有client知道.
六、 内部测试
1、测试上传文件的选组方式。
#func：上传文件的选组方式。
#valu：0、1或2。
# 0：表示轮询
# 1：表示指定组
# 2：表示存储负载均衡（选择剩余空间最大的组）
store_lookup=2
测试环境建立group1（172.16.23.173、172.16.23.175）、group2（172.16.23.172）；172.16.23.172挂在10G磁盘空间，默认store_lookup=2，当两个组同时活动时客户端测试上传文件默认到组group2（172.16.23.172）。
2、测试group2组宕机下线
group2（172.16.23.172）服务器关机，文件上传时上传group2报错，大约30秒后文件上传测试重新现在group1上传成功。选择对storage 服务器下线处理。
/usr/local/bin/fdfs_monitor /etc/fdfs/client.conf -h 172.16.23.176 delete group1 172.16.23.173
3、 测试组group1中storang server宕机
Group 中172.16.23.173宕机，测试上传至172.16.23.175读取成功。
七、 Http下载方式
1、tracker跳转方式：通过Tracker server跳转：Tracker server上需使用内置web server，Storage server可以使用内置web server或使用外部web server，推荐使用外部web server如apache或nginx。
2、非tracker跳转方式（使用扩展模块方式）：Storage server直接提供文件下载：tracker server上不需要任何web server，在每台storage server上部署web server，直接对外提供HTTP服务目前已提供apache和nginx扩展模块推荐使用扩展模块方式。
FastDFS扩展模块要点：
?使用扩展模块来解决文件同步延迟问题
?在每台storage server上部署web server，直接对外提供HTTP服务
?tracker server上不需要部署web server，开启http服务。
?如果请求文件在当前storage上不存在，通过文件ID反解出源storage，直接请求源storage
?目前已提供apache和nginx扩展模块 FastDFS扩展模块不依赖于FastDFS server，可以独立存在！
模块工作机制：
?对请求URL中的文件名进行反解，得到文件创建时间、文件大小和源storage server IP地址
? 如果文件在本地存在，直接返回文件内容；否则转3
? 文件在本地不存在的情况处理：
1）如果 (当前时间 - 文件创建时间) > 文件同步延迟阀值（如一天） 或者 源storage server IP地址在本机IP中（即当前文件上传到的源storage server为本机），则返回404 NOT FOUND
2）如果配置为redirect模式，直接重定向到源storage server IP对应的URL；否则为proxy模式，调用FastDFS client API从源storage server IP获取该文件并返回给客户端
? nginx的fdfs扩展模块后，就使用nginx的负载均衡，向tracker server获取两个参数而已，这两个参数是：
storage_sync_file_max_delay：文件同步的最大延迟，缺省为1天
storage_sync_file_max_time：同步单个文件需要的最大时间，缺省为5分钟。
3.推荐的FastDFS部署方案
?文件上传和删除等操作：使用FastDFS client API，目前提供了C、PHP extension和Java的client API
?文件下载采用HTTP方式：使用nginx或者apache扩展模块，不推荐使用FastDFS内置的web server
?不要做RAID，直接挂载单盘，每个硬盘作为一个mount point
Tracker server的性能非常高，一个较大的集群（比如上百个group）中有3台就足够了。
八、FastDFS注意事项
1. 除了在storage.conf里的tracker_server增加tracker的ip和端口，其他地方要注意什么？
tracker server ip和端口，肯定是要正确设置的。支持多tracker server，每行设置一个tracker。另外，base_path也要正确设置。其余参数，通常采用缺省配置即可。
2. 每台tracker和storage的启动有没有先后关系？
正常情况下，应该先启动tracker。FastDFS不会有这样的要求，你要启动storage也是没有任何问题的。
3. fastDFS产生的记录清空，再重新搭建一次，应该删除哪些文件？
停止storage server和tracker server，删除base_path下的data子目录即可。注意：storage 的data目录下保存了上传文件，删除时请慎重。
4. 这些Track Server的内容是对等的，还是分组，每个Track Server负责一部分Storage Server?
对等的。
Client是绑定一个Track Server，还是可以绑定多个或全部？
在一个集群中，应该绑定全部。
Storage Server也是同样的问题，是绑定一个Track Server，还是可以多个或者全部？
在一个集群中，应该绑定全部。
5. FastDFS存储服务器的硬盘挂载
FastDFS存储服务器的硬盘可以做RAID，比如RAID5等等，这样系统中的mount point只有一个。也可以单个硬盘直接mount使用，这样系统中的mount point就是多个（多个硬盘的情况下）。RAID5并不能充分发挥各个磁盘的最大吞吐量，出于磁盘IO效率考虑，建议采用第二种做法，这样磁盘整体IO吞吐量最理想的情况下，为各个硬盘IO吞吐量之和。
采用多个mount point的情况下，如果有一块硬盘损坏，可以有两种修复方法：
1. 更换掉坏掉的硬盘，在服务停止的情况下，手工复制已有服务器上该路径的文件到该mount point，然后启动FastDFS服务程序fdfs_storaged；
2. 更换一台同样配置的新服务器，或者更换掉坏的硬盘后，重做系统，然后启动FastDFS服务fdfs_storaged即可。
只要${base_path}这个路径所在硬盘没有坏，也就是系统数据文件（如${base_path}/data/sync/*）都在的情况下，文件自动同步是没有任何问题的。
6. 组内新增加一台storage server A时，由系统自动完成已有数据同步，处理逻辑
tracker server的配置文件中没有出现storage server，而storage server的配置文件中会列举出所有的tracker server。这就决定了storage server和tracker server之间的连接由storage server主动发起，storage server为每个tracker server启动一个线程进行连接和通讯，这部分的通信协议请参阅《FastDFS HOWTO -- Protocol》中的“2. storage server to tracker server command”。
tracker server会在内存中保存storage分组及各个组下的storage server，并将连接过自己的storage server及其分组保存到文件中，以便下次重启服务时能直接从本地磁盘中获得storage相关信息。storage server会在内存中记录本组的所有服务器，并将服务器信息记录到文件中。tracker server和storage server之间相互同步storage server列表：
<1>. 如果一个组内增加了新的storage server或者storage server的状态发生了改变，tracker server都会将storage server列表同步给该组内的所有storage server。以新增storage server为例，因为新加入的storage server主动连接tracker server，tracker server发现有新的storage server加入，就会将该组内所有的storage server返回给新加入的storage server，并重新将该组的storage server列表返回给该组内的其他storage server；
<2>. 如果新增加一台tracker server，storage server连接该tracker server，发现该tracker server返回的本组storage server列表比本机记录的要少，就会将该tracker server上没有的storage server同步给该tracker server。
同一组内的storage server之间是对等的，文件上传、删除等操作可以在任意一台storage server上进行。文件同步只在同组内的storage server之间进行，采用push方式，即源服务器同步给目标服务器。以文件上传为例，假设一个组内有3台storage server A、B和C，文件F上传到服务器B，由B将文件F同步到其余的两台服务器A和C。我们不妨把文件F上传到服务器B的操作为源头操作，在服务器B上的F文件为源头数据；文件F被同步到服务器A和C的操作为备份操作，在A和C上的F文件为备份数据。同步规则总结如下：
<1>. 只在本组内的storage server之间进行同步；
<2>. 源头数据才需要同步，备份数据不需要再次同步，否则就构成环路了；
<3>. 上述第二条规则有个例外，就是新增加一台storage server时，由已有的一台storage server将已有的所有数据（包括源头数据和备份数据）同步给该新增服务器。
storage server有7个状态，如下：
# FDFS_STORAGE_STATUS_INIT :初始化，尚未得到同步已有数据的源服务器
# FDFS_STORAGE_STATUS_WAIT_SYNC :等待同步，已得到同步已有数据的源服务器
# FDFS_STORAGE_STATUS_SYNCING :同步中
# FDFS_STORAGE_STATUS_DELETED :已删除，该服务器从本组中摘除（注：本状态的功能尚未实现）
# FDFS_STORAGE_STATUS_OFFLINE :离线
# FDFS_STORAGE_STATUS_ONLINE :在线，尚不能提供服务
# FDFS_STORAGE_STATUS_ACTIVE :在线，可以提供服务
当storage server的状态为FDFS_STORAGE_STATUS_ONLINE时，当该storage server向tracker server发起一次heart beat时，tracker server将其状态更改为FDFS_STORAGE_STATUS_ACTIVE。
组内新增加一台storage server A时，由系统自动完成已有数据同步，处理逻辑如下：
<1>. storage server A连接tracker server，tracker server将storage server A的状态设置为FDFS_STORAGE_STATUS_INIT。storage server A询问追加同步的源服务器和追加同步截至时间点，如果该组内只有storage server A或该组内已成功上传的文件数为0，则没有数据需要同步，storage server A就可以提供在线服务，此时tracker将其状态设置为FDFS_STORAGE_STATUS_ONLINE，否则tracker server将其状态设置为FDFS_STORAGE_STATUS_WAIT_SYNC，进入第二步的处理；
<2>. 假设tracker server分配向storage server A同步已有数据的源storage server为B。同组的storage server和tracker server通讯得知新增了storage server A，将启动同步线程，并向tracker server询问向storage server A追加同步的源服务器和截至时间点。storage server B将把截至时间点之前的所有数据同步给storage server A；而其余的storage server从截至时间点之后进行正常同步，只把源头数据同步给storage server A。到了截至时间点之后，storage server B对storage server A的同步将由追加同步切换为正常同步，只同步源头数据；
<3>. storage server B向storage server A同步完所有数据，暂时没有数据要同步时，storage server B请求tracker server将storage server A的状态设置为FDFS_STORAGE_STATUS_ONLINE；
<4>. 当storage server A向tracker server发起heart beat时，tracker server将其状态更改为FDFS_STORAGE_STATUS_ACTIVE。
9. Storage 2: ip_addr = 172.16.23.173 RECOVERY 问题
单盘故障恢复中。。。原因：采用多store path，更换group造成应避免。
10．Tracker和storage或storage之间时间要一致
11.上传后原文件名和上传后生成新的文件名的对应关系
上传前为test.txt,上传后生成rBAXrVAfNqSRJqy3AAAABWFXmN8243_big.tx
要实现文件Id映射，可以使用my-fastdfs-client, 需要保存原始文件名的话需要由应用端来保存这个映射关系。
12.两个磁盘都给FastDFS使用，在nginx配置两个location
location /group1/M00/ {
alias /fastdfs1/data/;
}
location /group1/M01/ {
alias /fastdfs2/data/;
}
13.Fdfs升级
从新编译安装Fdfs和Nginx+Nginx扩展模块,配置文件无需更改
八、 应用场景
Nginx配置：
upstream webservergroup1 {
