0\在windows eclipse 下的编译
首先建一个hello 工程,并且能编译通过,然后把FastDfs文件目录copy到 src目录下
a:设置环境变量 CYGWIN_HOME
b:在properties中的c/c++ build的build command设置 ${CYGWIN_HOME}/bin/sh.exe /cygdrive/u/programe/testproject/test/src/FastDFS/make.sh
1\基本配置
参看install
主要是调路径,端口号等
2\如果要支持http Server
配 置
tracker.conf ,把##include http.conf改成 #include http.conf
storage.conf ,把##include http.conf改成 #include http.conf
修改mash.sh 把 #WITH_HTTPD=1 改成 WITH_HTTPD=1(重要)
安装libEvent库
1. # tar xzvf libevent-2.0.4-alpha.tar.gz
2. # cd libevent-2.0.4
3. # ./configure --prefix=/home/super/installLIB
4. # make
5. # make install
3\执行
./make.sh
./make.sh install (如果要卸载,./make.sh clean)
可能会出现
error while loading shared libraries: libevent_core.so.3: cannot open shared object file: No such file or directory
[root@bogon bin]# ./fdfs_trackerd /fastdfs/FastDFS/conf/tracker.conf
./fdfs_trackerd: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory
执行
ln -s /home/super/installLIB/lib/libevent_core.so.3 /lib/libevent_core.so.3
4\注意
运行情况请看日志文件
trackerd.log
storaged.log
它们具体内容如下

5\上传图片后(参看install文件)
则返回 http://192.168.247.128:8080/group1/M00/00/00/wKj3gEvd84oAAAAAAABdrVV-uEs424_big.jpg
在ie中执行 http://192.168.247.128:8080/group1/M00/00/00/wKj3gEvd84oAAAAAAABdrVV-uEs424_big.jpg 看到此图片正常运行

>> 3.store_path这个参数的作用
同一个GROUP中的store_path目录个数必须大小一样,但目录名称可以不相同。
>> 4.能直接访问吗?我认为不能?
可以配合apache使用。在存储服务器上安装apache,将DocumentRoot配置到${base_path}/data目录。
以前有人问过类似的问题,参阅:http://linux.chinaunix.net/bbs/thread-1062825-1-1.html
2.其它这个10台电脑.用rsync就可能实现.好像也没有必要使用fast-dfs吧!
问题一
无法断点调试,断点时报错如下,
Can't find a source file at "/cygdrive/d/eclipse-cpp/workspaces/easyhello/easyhello.cpp"
Locate the file or edit the source lookup path to include its location.
解决:
must provide a mapping from /cygdrive/d to d:\ (or whatever your drive letter is).
in the eclipse IDE, go to menu Window -> Preferences -> C/C++ -> Debug-> Common Source Lookup Path -> Add.
增加一个Path Mapping
名字debugmapping 点击 add
Compilation path ---->/cygdrive/d
Local File System Path ---> d:\
Select OK to finish the dialogs.
注意(Windows平台下),特别要在
make.sh 中加入如下三行
cd /cygdrive/j
cd /cygdrive/j/fastdfs/fastv1.21_twoDevelope/fdstdfs/dfsfast/src/FastDFS
pwd
1、FastDFS底层技术及协议
2、在测试环境中分次搭建如下测试环境
a、一个Tracker Service ,一个Storage Service
a、一个Tracker Service ,多个Storage Service 测试两个 ok
b、多个Tracek Service ,多个Storage Service 都两个,测试中
c、多个分组,每个分组包括一个Tracker Service ,多个Storage Service
d、多个分组,多个Tracek Service ,多个Storage Service

一台机可以配置多个组,每个组都需要一套conf文件,
上传文件通过指定组的方式,没问题
不指定组的方式,直接把两个组都包括进去会怎样呢(不行,要以指定组的方式才可以)
[root@bogon fdfs]# /usr/local/bin/fdfs_append_file client.conf group1/M00/00/00/wKgAgU1_mF_vb_LiAMDAAJQUX_s782.exe /testdata/shankejingling_gerenban.exe
说明 fastdfs-apache-module_v1.04 的工作方式
另外一个解决方案:使用web server扩展模块方式,通过storage server上部署的web server直接对用户提供HTTP下载服务。此时tracker server上不需要开启HTTP服务。
模块工作机制:
1. 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
2. 如果文件在本地存在,直接返回文件内容;否则转3
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
目前已开发完成apache模块,正在测试阶段。
安装 apache
1. 源码包:httpd-2.2.6.tar.gz 从 www.apache.org 下载到此目录下:/usr/local/src 同时在 /usr/local 下创建一个httpd目录:mkdir httpd
2. 解压安装包:tar -zxvf httpd-2.2.6.tar.gz
3. 进入解压后的安装包:cd httpd-2.2.6
4. 配置:./configure --prefix=/usr/local/apache2 --enable-cgi ( 意义支持CGI)
5. 编译:make
6. 安装:make install
7. 启动web服务:
安装后fastdfs-apache-module_v1.04
启动apache 时报

Apache版本httpd-2.2.3-11.el5_1.centos.3
欲将www主目录设置为/home/www/html,目录权限如下

httpd.conf配置文件如下
DocumentRoot "/home/www/html"
执行/etc/rc.d/init.d/httpd start出现如下错误
启动 httpd:Syntax error on line 281 of /etc/httpd/conf/httpd.conf:

[失败]
如将DocumentRoot "/home/www/html"替换为DocumentRoot "/var/www/html"
则启动成功。。。
/var/www/html权限如下
drwxr-xr-x 2 root root 4096 01-16 09:36 /var/www/html
百思不得其解。。。望哪位大大告知。。。
seigfied继续试验,设置DocumentRoot "/home/seigfied"
/home/seigfied权限为
drwx------ 2 seigfied seigfied 4096 01-11 17:33 /home/seigfied
执行/etc/rc.d/init.d/httpd start,启动成功
真的没弄明白,/home/www/html明明就是一个目录。。
为什么Apache会告诉我DocumentRoot必须是一个目录呢
kenduest一般通常都是 selinux 問題。
請修改目錄的 security content,讓 apache 有存取該目錄的權限。
另外該相同問題於 linux.vbird.org 您有問過。

fastdfs-apache-module 有关返回原始文件名的问题
问:
之前看到happy_fish100如下说
模块工作机制:
1. 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
2. 如果文件在本地存在,直接返回文件内容;否则转3
3. 文件在本地不存在的情况处理:

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
=======================================================
我已测试过fastdfs-apache-module,很好用,解决了文件延时问题,有可起到分流分压的作用,有如下问题想问一下
具体问题描述
我有一个文件名叫 "540个活动营销策略.doc" 上传后假如文件名是wKj3gEvd84oAAAAAAABdrVV-uEs424.doc,我想通过redirect的模式在下载时直接返回"540个活动营销策略.doc"(即原始文件名),不知道有没有办法做到,我也看到happy_fish100说过,文件名在通过客户端上传时可以写到属性中,如“540个活动营销策略.doc”写到属性中,但下载(直接下载或用flashget之类的工具)怎样能返回原始中文名(我的站点是做文档分享的)呢,我也想过可不可通过fastdfs-apache-module 在内部进行处理,还请happy_fish100回复
======================================================================================
happy_fish100 回答:
已经有用户提出过这个需求了,呵呵。
原始文件名由应用记录到数据库中,生成下载链接时,URL参数中指定原始文件名,对应的参数名为:filename。
问(由于没及时看到回答,又问):
有过这样的回答:
可以使用文件附加属性来存储该文件的原文件名。在apache或nginx扩展模块中,可以在HTTP Header中输出原文件名。
happy_fish100 回答:
不推荐使用文件附件属性的方式保存原始文件名。
建议原始文件名由应用保存到数据库中。参见我上面的回复。
URL中指定参数filename,例如:filename=xxxx.doc
问:
happy_fish100 ,你好,谢谢你的回复,
QUOTE:已经有用户提出过这个需求了,呵呵。
原始文件名由应用记录到数据库中,生成下载链接时,URL参数中指定原始文件名,对应的参数名为:filename。
你上面说的 filename参数,是特别在fastdfs-apache-module 作过处理的吗?即通过如00/00/wKgAgk1_M36eGCazAAHAC_MLulA790.doc ?filename=540个活动营销策略.doc 样式访问文件,
通过 00/00/wKgAgk1_M36eGCazAAHAC_MLulA790.doc 定位磁盘文件,而filename是用户保存数据文件时的文件名,可以这样理解吗,我想应该是这样,如果是这样,太好了,我的问题解决了
happy_fish100 回答:
是的,你的理解完全正确。
不过文件名中包含中文,因为字符集问题,可能会导致另存时,显示的文件名为乱码。
问:
太谢谢happy_fish100 ,谢谢happy_fish100的提醒
QUOTE:是的,你的理解完全正确。
不过文件名中包含中文,因为字符集问题,可能会导致另存时,显示的文件名为乱码。
这个与apache本身的httpd.conf 的配置文件有关吧,可以让httpd.conf的字符集与网页字符集相应调整,可以解决吧
总之,可以通过如下方法访问物理磁盘文件名

0\在windows eclipse 下的编译
首先建一个hello 工程,并且能编译通过,然后把FastDfs文件目录copy到 src目录下
a:设置环境变量 CYGWIN_HOME
b:在properties中的c/c++ build的build command设置 ${CYGWIN_HOME}/bin/sh.exe /cygdrive/u/programe/testproject/test/src/FastDFS/make.sh
1\基本配置
参看install
主要是调路径,端口号等
2\如果要支持http Server
配 置
tracker.conf ,把##include http.conf改成 #include http.conf
storage.conf ,把##include http.conf改成 #include http.conf
修改mash.sh 把 #WITH_HTTPD=1 改成 WITH_HTTPD=1(重要)
安装libEvent库
1. # tar xzvf libevent-2.0.4-alpha.tar.gz
2. # cd libevent-2.0.4
3. # ./configure --prefix=/home/super/installLIB
4. # make
5. # make install
3\执行
./make.sh
./make.sh install (如果要卸载,./make.sh clean)
可能会出现
error while loading shared libraries: libevent_core.so.3: cannot open shared object file: No such file or directory
[root@bogon bin]# ./fdfs_trackerd /fastdfs/FastDFS/conf/tracker.conf
./fdfs_trackerd: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory
执行
ln -s /home/super/installLIB/lib/libevent_core.so.3 /lib/libevent_core.so.3
4\注意

一台机可以配置多个组,每个组都需要一套conf文件,
上传文件通过指定组的方式,没问题
不指定组的方式,直接把两个组都包括进去会怎样呢(不行,要以指定组的方式才可以)
[root@bogon fdfs]# /usr/local/bin/fdfs_append_file client.conf group1/M00/00/00/wKgAgU1_mF_vb_LiAMDAAJQUX_s782.exe /testdata/shankejingling_gerenban.exe
说明 fastdfs-apache-module_v1.04 的工作方式
另外一个解决方案:使用web server扩展模块方式,通过storage server上部署的web server直接对用户提供HTTP下载服务。此时tracker server上不需要开启HTTP服务。
模块工作机制:
1. 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
2. 如果文件在本地存在,直接返回文件内容;否则转3
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
目前已开发完成apache模块,正在测试阶段。
安装 apache
1. 源码包:httpd-2.2.6.tar.gz 从 www.apache.org 下载到此目录下:/usr/local/src 同时在 /usr/local 下创建一个httpd目录:mkdir httpd
2. 解压安装包:tar -zxvf httpd-2.2.6.tar.gz
3. 进入解压后的安装包:cd httpd-2.2.6
4. 配置:./configure --prefix=/usr/local/apache2 --enable-cgi ( 意义支持CGI)
5. 编译:make
6. 安装:make install
7. 启动web服务:
安装后fastdfs-apache-module_v1.04
启动apache 时报

Apache版本httpd-2.2.3-11.el5_1.centos.3
欲将www主目录设置为/home/www/html,目录权限如下

httpd.conf配置文件如下
DocumentRoot "/home/www/html"
执行/etc/rc.d/init.d/httpd start出现如下错误
启动 httpd:Syntax error on line 281 of /etc/httpd/conf/httpd.conf:

如将DocumentRoot "/home/www/html"替换为DocumentRoot "/var/www/html"
则启动成功。。。
/var/www/html权限如下
drwxr-xr-x 2 root root 4096 01-16 09:36 /var/www/html
百思不得其解。。。望哪位大大告知。。。
seigfied继续试验,设置DocumentRoot "/home/seigfied"
/home/seigfied权限为
drwx------ 2 seigfied seigfied 4096 01-11 17:33 /home/seigfied
执行/etc/rc.d/init.d/httpd start,启动成功
真的没弄明白,/home/www/html明明就是一个目录。。
为什么Apache会告诉我DocumentRoot必须是一个目录呢
kenduest一般通常都是 selinux 問題。
請修改目錄的 security content,讓 apache 有存取該目錄的權限。
chcon -R -t httpd_sys_content_t /home/www/html
另外該相同問題於 linux.vbird.org 您有問過。

fastdfs-apache-module 有关返回原始文件名的问题
引用
问:
之前看到happy_fish100如下说
模块工作机制:
1. 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
2. 如果文件在本地存在,直接返回文件内容;否则转3
3. 文件在本地不存在的情况处理:

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
=======================================================
我已测试过fastdfs-apache-module,很好用,解决了文件延时问题,有可起到分流分压的作用,有如下问题想问一下
具体问题描述
我有一个文件名叫 "540个活动营销策略.doc" 上传后假如文件名是wKj3gEvd84oAAAAAAABdrVV-uEs424.doc,我想通过redirect的模式在下载时直接返回"540个活动营销策略.doc"(即原始文件名),不知道有没有办法做到,我也看到happy_fish100说过,文件名在通过客户端上传时可以写到属性中,如“540个活动营销策略.doc”写到属性中,但下载(直接下载或用flashget之类的工具)怎样能返回原始中文名(我的站点是做文档分享的)呢,我也想过可不可通过fastdfs-apache-module 在内部进行处理,还请happy_fish100回复
======================================================================================
happy_fish100 回答:
已经有用户提出过这个需求了,呵呵。
原始文件名由应用记录到数据库中,生成下载链接时,URL参数中指定原始文件名,对应的参数名为:filename。
问(由于没及时看到回答,又问):
有过这样的回答:
可以使用文件附加属性来存储该文件的原文件名。在apache或nginx扩展模块中,可以在HTTP Header中输出原文件名。
happy_fish100 回答:
不推荐使用文件附件属性的方式保存原始文件名。
建议原始文件名由应用保存到数据库中。参见我上面的回复。
URL中指定参数filename,例如:filename=xxxx.doc
问:
happy_fish100 ,你好,谢谢你的回复,
QUOTE:已经有用户提出过这个需求了,呵呵。
原始文件名由应用记录到数据库中,生成下载链接时,URL参数中指定原始文件名,对应的参数名为:filename。
你上面说的 filename参数,是特别在fastdfs-apache-module 作过处理的吗?即通过如00/00/wKgAgk1_M36eGCazAAHAC_MLulA790.doc ?filename=540个活动营销策略.doc 样式访问文件,
通过 00/00/wKgAgk1_M36eGCazAAHAC_MLulA790.doc 定位磁盘文件,而filename是用户保存数据文件时的文件名,可以这样理解吗,我想应该是这样,如果是这样,太好了,我的问题解决了
happy_fish100 回答:
是的,你的理解完全正确。
不过文件名中包含中文,因为字符集问题,可能会导致另存时,显示的文件名为乱码。
问:
太谢谢happy_fish100 ,谢谢happy_fish100的提醒
QUOTE:是的,你的理解完全正确。
不过文件名中包含中文,因为字符集问题,可能会导致另存时,显示的文件名为乱码。
这个与apache本身的httpd.conf 的配置文件有关吧,可以让httpd.conf的字符集与网页字符集相应调整,可以解决吧
总之,可以通过如下方法访问物理磁盘文件名
