❶ 谁用过fastDFS上传文件，能不能分享点经验
一. 应用系统在上传文件到FastDFS成功时将原始文件名和“文件索引（FID）”保存下来（例如：保存到数据库）。
二. 用户点击下载的时用Nginx的域名和FID拼出url，然后在url后面增加一个参数，指定原始文件名。例如：http://121.14.161.48:9030/group2/M00/00/89/eQ6h3FKJf_PRl8p4AUz4wO8tqaA688.apk?attname=filename.apk
三. 在Nginx上进行如下配置，这样Nginx就会截获url中的参数attname，在Http响应头里面加上字段 Content-Disposition “attachment;filename=$arg_attname”。
location /group2/M00 {
root /data/store/data;
if ($arg_attname ~ "^(.*).apk") {
add_header Content-Disposition "attachment;filename=$arg_attname";
}
ngx_fastdfs_mole;
}

四. 浏览器发现响应头里面有Content-Disposition “attachment;filename=$arg_attname”时，就会把文件名显示成filename指定的名称。
❷ 如何在Linux系统中安装配置FastDFS软件
在Linux系统中进行FastDFS软件的安装配置，方法的过程中是很复杂的，所以如果不是专业的电脑高手可能是没有办法整理出来，所以为了方便网友们更好的了解这个软件的安装，一下就是详细的过程，大家一起来看看吧！
第一步：安装FastDFS
1.解压 FastDFS_v4.07.tar.gz ==>FastDFS
2. cd FastDFS ==>vim make.sh
修改以下内容
TARGET_PREFIX=/usr/local/fdfs
TARGET_CONF_PATH=/usr/local/fdfs/conf
mkdir -p /usr/local/fdfs
mkdir -p /usr/local/fdfs/conf
修改
if [ "$uname" = "Linux" ]; then
if [ "$WITH_LINUX_SERVICE" = "1" ]; then
if [ ! -d $TARGET_CONF_PATH ]; then
mkdir -p $TARGET_CONF_PATH
cp -f conf/tracker.conf $TARGET_CONF_PATH
cp -f conf/storage.conf $TARGET_CONF_PATH
cp -f conf/client.conf $TARGET_CONF_PATH
cp -f conf/http.conf $TARGET_CONF_PATH
cp -f conf/mime.types $TARGET_CONF_PATH
fi
cp -f init.d/fdfs_trackerd /etc/rc.d/init.d/
cp -f init.d/fdfs_storaged /etc/rc.d/init.d/
/sbin/chkconfig --add fdfs_trackerd
/sbin/chkconfig --add fdfs_storaged
fi
fi
第二步：安装libevent-2.0.19-stable.tar.gz
1.解压 libevent-2.0.19-stable.tar.gz==>libevent-2.0.19-stable
2.进入libevent-2.0.19-stable 安装
./configure --prefix=/usr/local/libevent
make
make install
3. 添加软连接
ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/lib/libevent-2.0.so.5
ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5
ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /lib64/libevent-2.0.so.5
ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /lib/libevent-2.0.so.5
ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/local/lib64/libevent-2.0.so.5
ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/local/lib/libevent-2.0.so.5
第三步：安装FastDFS
./make.sh C_INCLUDE_PATH=/usr/local/libevent/include LIBRARY_PATH=/usr/local/libevent/lib
./make.sh install
第四步:如果/usr/local/fastdfs/conf没有fdfs_trackerd和fdfs_storaged这两个文件，就从 /FastDFS/tracker 和FastDFS/storage/目录下复制过去
第五步:修改配置
mkdir -p /home/softinstall/data/tracker
1. 修改 tracker.conf
base_path=/home/softinstall/data/tracker
bind_addr=192.168.9.169
1.1 修改storage_ids.conf
100001 group1 192.168.9.169
2. 启动tracker
./fdfs_trackerd ../conf/tracker.conf
查看22122端口是否启动起来
第六步：配置storage
mkdir -p /home/softinstall/data/store
mkdir -p /home/softinstall/data/store/store0
mkdir -p /home/softinstall/data/store/store1
mkdir -p /home/softinstall/data/store/store2
1.修改storage.conf
base_path=/home/softinstall/data/store
store_path_count=3
store_path0=/home/softinstall/data/store/store0
store_path1=/home/softinstall/data/store/store1
store_path2=/home/softinstall/data/store/store2
tracker_server=192.168.9.169:22122
#限6*6=36个目录 默认256*256
subdir_count_per_path=6
2. 启动storage
./fdfs_storaged ../conf/storage.conf
查看23000端口是否启动
第七步：安装nginx+fastdfs模块
1. 安装pcre-8.32
进入pcre-8.32
./configure
make
make install
安装如果有问题缺省某些包，可以执行:
yum groupinstall "Development Tools"
第八步：解压fastdfs-nginx-mole_v1.15.tar.gz和 nginx-1.4.2.tar.gz
1.进入 fastdfs-nginx-mole_v1.15/src
vim fastdfs-nginx-mole_v1.15/src/config
修改成以下内容
ngx_addon_name=ngx_http_fastdfs_mole
HTTP_MODULES="$HTTP_MODULES ngx_http_fastdfs_mole"
NGX_ADDON_SRCS="$NGX_ADDON_SRCS $ngx_addon_dir/ngx_http_fastdfs_mole.c"
CORE_INCS="$CORE_INCS /usr/local/fdfs/include/fastdfs /usr/local/fdfs/include/fastcommon/"
CORE_LIBS="$CORE_LIBS -L/usr/local/fdfs/lib -lfastcommon -lfdfsclient"
CFLAGS="$CFLAGS -D_FILE_OFFSET_BITS=64 -DFDFS_OUTPUT_CHUNK_SIZE='256*1024' -DFDFS_MOD_CONF_FILENAME='\"/usr/local/fdfs/conf/mod_fastdfs.conf\"'"
2. 安装
进入nginx-1.4.2目录
./configure --prefix=/home/softinstall/nginx/nginx-fastdfs-install --with-pcre=/home/softinstall/nginx/pcre-8.32 --add-mole=/home/softinstall/nginx/fastdfs-nginx-mole/src
安装中如果有问题
可以执行安装以下包:yum -y install gcc gcc-c++ zlib-devel openssl-devel
3.配置nginx.conf
进入nginx-fastdfs-install/conf
vim nginx.conf 配置以下内容
location /M00 {
root /home/softinstall/data/store/store0/data;
ngx_fastdfs_mole;
}
location /M01 {
root /home/softinstall/data/store/store1/data;
ngx_fastdfs_mole;
}
location /M02 {
root /home/softinstall/data/store/store2/data;
ngx_fastdfs_mole;
}
4.配置mod_fastdfs.conf
mkdir -p /home/softinstall/data/nginx_mod
进入 /usr/local/fdfs/conf目录
vim mod_fastdfs.conf
base_path=/home/softinstall/data/nginx_mod
tracker_server=192.168.9.169:22122
store_path_count=3
store_path0=/home/softinstall/data/store/store0
store_path1=/home/softinstall/data/store/store1
store_path2=/home/softinstall/data/store/store2
5. 启动nginx
进入 /home/softinstall/nginx/nginx-fastdfs-install/sbin
./nginx
如果启动找不到
error while loading shared libraries: libfdfsclient.so: cannot open shared object file: No such file or directory
error while loading shared libraries: libfastcommon.so: cannot open shared object file: No such file or directory
请使用以下软连接
ln -s /usr/local/fdfs/lib/libfastcommon.so /usr/lib/libfastcommon.so
ln -s /usr/local/fdfs/lib/libfastcommon.so /usr/lib64/libfastcommon.so
ln -s /usr/local/fdfs/lib/libfdfsclient.so /usr/lib64/libfdfsclient.so
ln -s /usr/local/fdfs/lib/libfdfsclient.so /usr/lib/libfdfsclient.so
==========================fastDHT================================
【第一步:】安装 Berkley DB
【1.】 tar -zxvf db-4.7.25.tar.gz
进入 db-4.7.25/build_unix
../dist/configure --prefix=/usr
【第二步:】安装FastDHT
mkdir -p /usr/local/fdht
mkdir -p /usr/local/fdht/conf
1. tar -zxvf FastDHT_v1.23.tar.gz
进入 FastDHT_v1.23
vim make.sh
修改
TARGET_PREFIX=/usr/local/fdht
TARGET_CONF_PATH=/usr/local/fdht/conf
if [ "$1" = "install" ]; then
cd ..
cp -f restart.sh $TARGET_PREFIX/bin
cp -f stop.sh $TARGET_PREFIX/bin
if [ "$uname" = "Linux" ]; then
if [ "$WITH_LINUX_SERVICE" = "1" ]; then
if [ ! -d $TARGET_CONF_PATH ]; then
mkdir -p $TARGET_CONF_PATH
cp -f conf/fdhtd.conf $TARGET_CONF_PATH
cp -f conf/fdht_servers.conf $TARGET_CONF_PATH
cp -f conf/fdht_client.conf $TARGET_CONF_PATH
fi
cp -f init.d/fdhtd /etc/rc.d/init.d/
/sbin/chkconfig --add fdhtd
fi
fi
fi
【2.】 安装
./make.sh
------------------------------------------------------------------------------
如果出现 global.h:18:19: error: event.h: No such file or directory
进入/home/softinstall/fastdfs/libevent-2.0.19-stable然后执行
./configure --prefix=/usr
make
make install
---------------------------------------------------------------------------------
./make.sh install
【3.】 配置fdht
【3.1】 vim /usr/local/fdht/conf/fdhtd.conf
port=11411
bash_path=/home/softinstall/data/fastdht
cache_size = 32MB
store_sub_keys=true
use_storage_id=true
#include /usr/local/fdht/conf/fdht_servers.conf (本行前有#表示打开，如果想关闭此选项，则应该为##开头)
【3.2】 vim /usr/local/fdht/conf/fdht_server.conf
group_count = 1
group0 = 192.168.9.165:11411
【3.3】 vim /usr/local/fdht/conf/fdht_client.conf
keep_alive=1 (本选项关联 storaged.conf文件)
base_path=/home/softinstall/data/fastdht
#include /usr/local/fdht/conf/fdht_servers.conf
【3.4】 配置FastDFS 的 storaged.conf文件
vi storaged.conf （默认位置： /usr/local/fdfs/conf/storaged.conf）
check_file_plicate=1
本配置项解释： 是否检测上传文件已经存在。如果已经存在，则不存在文件内容，建立一个索引链接以节省磁盘空间
key_namespace=FastDFS
本配置项解释： 当上个参数设定为1时 ， 在FastDHT中的命名空间
keep_alive=1
本配置项解释： 长连接配置选项，如果为0则为短连接 1为长连接
#include /usr/local/fdht/conf/fdht_servers.conf
本配置项解释： 可以通过 #include filename 方式来加载 FastDHT servers 的配置
【3.5】

=================================================================
❸ 初次用fastdfs，请教关于上传文件的问题
faq:9. fdfs_test和fdfs_test1是做什么用的？ 这两个是FastDFS自带的测试程序，会对一个文件上传两次，分别作为主文件和从文件。返回的文件ID也是两个。 并且会上传文件附加属性，storage server上会生成4个文件。
