FashDFS开发环境及配置

参考资源(以后经常补写)

问查询某个端口是否已被使用 
#netstat   -na   |grep   tcp   
  列出所有开放的TCP端口（已经占用的） 
netstat   -an   |   grep   8080 
  查询8080端口是否占用 

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 

   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
  trackerd.log

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


  6、
  查看端口号
     lsof -i :端口 号 
     lsof -i :8080

wget  -S file_url
wget  -S http://192.168.247.128:8888/group1/M00/00/00/wKj3gEvd84oAAAAAAABdrVV-uEs424_big.jpg 可以得到文件,并把文件保存在当前路径下

>> 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
