完整安装流程
下载的包都存放在~/caibh/fdfs-package目录下。
下载libfastcommon、fastdfs、fastdfs-nginx-module：
cd ~/caibh/fdfs-package
# -S print server response
# -O write documents to file
wget https://github.com/happyfish100/libfastcommon/archive/V1.0.39.tar.gz -SO libfastcommon.tar.gz
wget https://github.com/happyfish100/fastdfs/archive/V5.11.tar.gz -SO fastdfs.tar.gz
wget https://github.com/happyfish100/fastdfs-nginx-module/archive/V1.20.tar.gz -SO fastdfs-nginx-module.tar.gz
# 解压
tar -xf xxx.tar.gz 安装 libfastcommon
cd ~/caibh/fdfs-package
cd libfastcommon-1.0.39
./make.sh
./make.sh install安装 fastdfs
cd ~/caibh/fdfs-package
cd fastdfs-5.11
./make.sh
./make.sh install安装好后，程序是在/usr/bin目录下：
$ which fdfs_trackerd
/usr/bin/fdfs_trackerd而配置文件是在/etc/fdfs目录下：
$ cd ~/caibh/fdfs-package/fastdfs-5.11
$ ls /etc/fdfs
client.conf.sample storage_ids.conf.sample tracker.conf.sample storage.conf.sample但是这些配置文件是不全的，而且都是模板，所以需要从fastdfs包中拷贝过来，并修改配置：
$ cd ~/caibh/fdfs-package/fastdfs-5.11/conf
$ ls
anti-steal.jpg client.conf http.conf mime.types storage.conf storage_ids.conf tracker.conf
$ sudo cp ~/caibh/fdfs-package/fastdfs-5.11/conf/* /etc/fdfs修改配置
sudo vi /etc/fdfs/tracker.conf：
# the tracker server port
port=22122# the base path to store data and log files
base_path=/home/caibh/fdfs# HTTP port on this tracker server
http.server_port=9270sudo vi /etc/fdfs/storage.conf：
# storage所属的组
group_name=group1# the storage server port
port=23000# the base path to store data and log files
base_path=/home/caibh/fdfs# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
store_path0=/home/caibh/fdfs
#store_path1=/home/caibh/fdfs2# tracker服务器，虽然是同一台机器上，但是不能写127.0.0.1。这项配置可以出现一次或多次
tracker_server=191.8.1.77:22122# the port of the web server on this storage server
http.server_port=8888sudo vi /etc/fdfs/client.conf：
# the base path to store log files
base_path=/home/caibh/fdfs/client
# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=191.8.1.77:22122
#HTTP settings
http.tracker_server_port=9270sudo vi /etc/fdfs/mod_fastdfs.conf：
# the base path to store log files
base_path=/tmp# FastDFS tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
# valid only when load_fdfs_parameters_from_tracker is true
tracker_server=191.8.1.77:22122# the port of the local storage server
# the default value is 23000
storage_server_port=23000# the group name of the local storage server
group_name=group1# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
# must same as storage.conf
store_path0=/home/caibh/fdfs
#store_path1=/home/yuqing/fastdfs1配置过程中有几点要注意：
- 确保配置中用到的目录已经创建了。比如
~/fdfs/client、~/fdfs/data、~/fdfs/logs 确保各种配置文件之间引用的端口一直。比如：
mod_fastdfs.conf文件中tracker_server的端口应该跟tracker.conf中port一致；mod_fastdfs.conf文件中storage_server_port的端口应该跟跟storage.conf中port一致；
其他配置或文件虽然不用修改，但是
fastdfs-nginx-module模块会用到：anti-steal.jpghttp.confmime.types
启动tracker和storage：
# 启动
fdfs_trackerd /etc/fdfs/tracker.conf start
fdfs_storaged /etc/fdfs/storage.conf start
# 查看日志
tail -n10 ~/fdfs/logs/trackerd.log
tail -n10 ~/fdfs/logs/storaged.log
# 如果日志显示有错误信息，需要根据信息来查找错误原因用fdfs_test测试上传
$ fdfs_test /etc/fdfs/client.conf upload ~/caibh/test_images/XinXiJuZhiWang.jpg安装fastdfs-nginx-module
思路：
安装过程比较复杂，由于当前系统已经有一个nginx在运行了，所以要先确认当前系统nginx的版本，然后到官网下载对应版本的nginx源码，然后查看系统nginx的编译选项，用一模一样的编译选项外加
fastdfs-nginx-module的源码，重新编译一个nginx程序。用新的nginx替换系统的nginx。注意：
这里的安装场景是tracker和storage都装在同一个机器上。
查看已安装并在运行中的nginx的版本：
$ nginx -v
nginx version: nginx/1.10.3 (Ubuntu)到官网下载对应版本的nginx源码，并解压，改名为nginx-src，然后进入nginx-src目录
查看当前运行的ngxin原来的编译选项：
$ cd ~/caibh/nginx-src
$ nginx -V
nginx version: nginx/1.10.3 (Ubuntu)
built with OpenSSL 1.0.2g 1 Mar 2016
TLS SNI support enabled

$ cd ~/caibh/nginx-src
$ cat custom_configure.sh

# 如果能看到图片则表示安装fastdfs-nginx-module成功附录1：FastDFS 官网介绍
FastDFS是一款高性能的分布式文件系统。主要功能包括：文件存储，文件同步，文件访问（上传下载）。它可以解决高容量和负载均衡的问题。FastDFS适合用来做文件相关的网站，如图片分享、视频分享等。
FastDFS有两种角色：tracker和storage。tracker负责文件访问的跟踪和负载均衡。storage负责存储文件，它的功能包括：文件存储、文件同步、提供文件访问接口，storage还负责管理文件的元数据，这些数据是以键值对的形式表示的，如：width=1024，键是“width”，值是“1024”。
tracker和storage可以是一个或多个服务器。在tracker或storage的集群中，任何时候都可以从中删除服务器，对线上服务没有任何影响。tracker集群中的服务器是点对点的。
存储服务器以 卷/组 形式组织，以获取高容量。存储系统包括一个或多个卷，卷与卷之间的文件是相互独立的。整个存储系统的总容量等于所有卷的容量之和。一个文件卷包括一个或多个存储服务器，一个卷中的存储服务器之间的文件是一样的。一个文件卷中的服务器会互相备份，且这些服务器之间是负载均衡的。当添加一个存储服务器到一个卷的时候，卷中的文件会自动复制到新的服务器，复制完以后，系统会把新服务器切换到线上，已提供存储服务。
当存储容量不足时，你可以添加一个或多个卷来扩展存储容量。
一个文件的标识包括两部分：卷名和文件名
附录2：FastDFS官方INSTALL文件
step 1. 下载安装 libfastcommon地址：https://github.com/happyfish1...
step 2. 下载安装 FastDFS
解压：
tar xzf FastDFS_v5.08.tar.gzstep 3. 进入FastDFS的目录
cd FastDFSstep 4. 执行make:
./make.shstep 5. 执行make install
./make.sh installstep 6. 修改tracker和storage的配置文件：
/etc/fdfs/tracker.conf几个重要的配置：
# the tracker server port
port=22122# the base path to store data and log files
base_path=/home/caibh/fdfs# which group to upload file
# when store_lookup set to 1, must set store_group to the group name
store_group=group2# HTTP port on this tracker server
http.server_port=9270/etc/fdfs/storage.conf几个重要的配置：
# the storage server port
port=23000# the base path to store data and log files
base_path=/home/caibh/fdfs# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
store_path0=/home/caibh/fdfs
#store_path1=/home/caibh/fdfs2# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
# 在同一台机器上配置tracker和storage时，这里如果是127.0.0.1会报错，所以要配置真正的ip地址。
tracker_server=191.8.1.77:22122# the port of the web server on this storage server
http.server_port=8888
step 7. run server programs
启动tracker：
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restartin Linux, you can start fdfs_trackerd as a service:
/sbin/service fdfs_trackerd start启动storage：
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf restartin Linux, you can start fdfs_storaged as a service:
/sbin/service fdfs_storaged startstep 8. 测试
修改客户端配置文件：
/etc/fdfs/client.conf几个重要的配置：
# the base path to store log files
base_path=/home/caibh/fdfs/client# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=191.8.1.77:22122#HTTP settings
http.tracker_server_port=9270run the client test program:
/usr/bin/fdfs_test <client_conf_filename> <operation>
/usr/bin/fdfs_test1 <client_conf_filename> <operation>例如上传一个图片文件：
caibh@pc:~$ fdfs_test /etc/fdfs/client.conf upload /develop/fastdfs/test_file/LiuLangDiQiu.jpg

notice
info
debug - allow_hosts can ocur more than once, host can be hostname or ip address,
"*" means match all ip addresses, can use range like this: 10.0.1.[1-15,20]
or host[01-08,20-25].domain.com, for example:
