fastdfs 学习

fastdfs安装
1.编译安装 libevent-1.4.14b-stable

 $./configure
  $ make
  # make install

2.FastDFS v3.05
 

$./make.sh
  #./make.sh install

FastDFS安装使用实战二（配置篇）
1.

cd /etc/fdfs/

   修改tracker.conf文件,修改如下
2.

base_path=/home/liguojun/fastdfs_tracker

3.

http.server_port=8080 -> http.server_port=8090

  (http端口) 
4.

##include http.conf -> #include http.conf 

  (http支持)
5.

reserved_storage_space = 4GB -> reserved_storage_space = 1GB 

6.

port=22122

   (tracker server对storage server供服务的端口)
7.

cd /usr/local/bin/ 

8.

fdfs_trackerd /etc/fdfs/tracker.conf 

 (启动tracker服务器)
9.

cat /home/liguojun/fastdfs_tracker/logs/trackerd.log

查看日志
 
配置及启动Storage Server
1.

cd /etc/fdfs

  修改storage.conf文件，修改如下
2.

base_path=/home/yuqing/fastdfs -> /home/liguojun/fastdfs_storge

#文件的存储位置，在一台storage server上可以指定多个存储位置
#

store_path0=/home/yuqing/fastdfs -> store_path0=/home/liguojun/fastdfs_storge

3.

group_name=group1 

4.

tracker_server=192.168.209.121:22122 -> tracker_server=10.0.2.15:22122 

5.

##include http.conf ->#include http.conf  

6.

 cd /usr/local/bin/ 

7.

fdfs_storaged /etc/fdfs/storage.conf 

8.

cat /home/liguojun/fastdfs_storge/logs/storaged.log

查看日志

FastDFS安装使用实战三（使用篇）
1.

cd /etc/fdfs

  修改client.conf文件，修改如下
2.

base_path=/home/yuqing/fastdfs-> base_path=/home/soar/fastdfs_tracker

3.

tracker_server=192.168.209.121:22122 -> tracker_server=10.0.2.15:22122 

4.

http.tracker_server_port=8080 ->http.tracker_server_port=8090

5.

##include http.conf ->#include http.conf

6.

cd /usr/local/bin/

7.
