fast DFS 单机使用实例

fast DFS 单机使用实例

我在一台服务器上简单测试了fastdfs。client, tracker, storage server都是同一个物理服务器。

 

1. 编译fastdfs：

 

sles207:/opt/mars/FastDFS # ./make.sh

 

storage_service.o: In function `storage_service_init':
/opt/mars/FastDFS/storage/storage_service.c:1100: undefined reference to `event_base_new'
storage_service.o: In function `work_thread_entrance':
/opt/mars/FastDFS/storage/storage_service.c:1364: undefined reference to `event_base_free'
collect2: ld returned 1 exit status
make: *** [fdfs_storaged] Error 1

没有装libevent，需下载安装。（http://monkey.org/~provos/libevent/）

 

 

2. 安装fastdfs：

 

sles207:/opt/mars/FastDFS # ./make.sh install
mkdir -p /usr/local/bin
mkdir -p /etc/fdfs
cp -f fdfs_trackerd  /usr/local/bin
if [ ! -f /etc/fdfs/tracker.conf ]; then cp -f ../conf/tracker.conf ../conf/mime.types ../conf/http.conf /etc/fdfs; fi
mkdir -p /usr/local/bin
mkdir -p /etc/fdfs
cp -f fdfs_storaged  /usr/local/bin
if [ ! -f /etc/fdfs/storage.conf ]; then cp -f ../conf/storage.conf ../conf/mime.types ../conf/http.conf /etc/fdfs; fi
mkdir -p /usr/local/bin
mkdir -p /etc/fdfs
mkdir -p /usr/local/lib
cp -f fdfs_monitor fdfs_test fdfs_test1 fdfs_crc32 fdfs_upload_file fdfs_download_file fdfs_delete_file fdfs_file_info fdfs_appender_test fdfs_appender_test1 fdfs_append_file fdfs_upload_appender /usr/local/bin
cp -f libfastcommon.so.1 libfdfsclient.so.1 /usr/local/lib
if [ ! -f /etc/fdfs/client.conf ]; then cp -f ../conf/client.conf ../conf/http.conf /etc/fdfs; fi
mkdir -p /usr/local/include
mkdir -p /usr/local/include/fastcommon
mkdir -p /usr/local/include/fastdfs
cp -f ../common/common_define.h ../common/hash.h ../common/chain.h ../common/logger.h ../common/base64.h ../common/shared_func.h ../common/pthread_func.h ../common/ini_file_reader.h ../common/sockopt.h ../common/sched_thread.h ../common/http_func.h ../common/md5.h ../common/_os_bits.h ../common/local_ip_func.h /usr/local/include/fastcommon
cp -f ../common/fdfs_define.h ../common/fdfs_global.h ../common/mime_file_parser.h ../common/fdfs_http_shared.h ../tracker/tracker_types.h ../tracker/tracker_proto.h tracker_client.h storage_client.h storage_client1.h client_func.h client_global.h fdfs_client.h /usr/local/include/fastdfs
#ln -fs /usr/local/lib/libfastcommon.so.1 /usr/local/lib/libfastcommon.so
#ln -fs /usr/local/lib/libfdfsclient.so.1 /usr/local/lib/libfdfsclient.so
sh ./fdfs_link_library.sh

3. 修改配置文件：

 

a. client.conf:

 

sles207:/etc/fdfs # cat client.conf

4. 启动tracker server：

                                                               
sles207:/etc/fdfs # /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf

5. 启动 storage server：

sles207:/etc/fdfs # /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf

....
