分布式文件系统FastDFS之HTTP服务详解

FastDFS是一个开源的轻量级分布式文件系统，它对文件进行管理，功能包括：文件存储、文件同步、文件访问（文件上传、文件下载）等，解决了大容量存储和负载均衡的问题。特别适合以文件为载体的在线服务，如相册网站、视频网站等等。FastDFS本身具备web服务器功能，但是在5.0版本以上的HTTP模式已被取消。nginx模块也很久未有更新。现在很多人都采用主流的七牛或者又拍云服务，个人觉得无论在速度还是时间上，又拍云完胜七牛。

接下来主要介绍一下FastDFS自带的http服务，在小型服务器上，这个还是简单好用的。注意下版本选择，需要在5.0一下版本才有此功能。

FastDFS 安装配置

[root@vanedev2 ~] wget –no-check-certificate https://github.com/downloads/libevent/libevent/libevent-2.0.20-stable.tar.gz
[root@vanedev2 ~] tar zxvf libevent-2.0.20-stable.tar.gz
[root@vanedev2 ~] cd libevent-2.0.20-stable/
[root@vanedev2 ~] ./configure –prefix=/usr/local/libevent
[root@vanedev2 ~] make -j8 && make install
[root@vanedev2 ~] echo “/usr/local/libevent/lib” >> /etc/ld.so.conf
[root@vanedev2 ~] ldconfig

[root@vanedev2 ~] wget https://fastdfs.googlecode.com/files/FastDFS_v3.11.tar.gz
[root@vanedev2 ~] cd FastDFS_v3.11.tar.gz
[root@vanedev2 ~] vi make.sh

开启http及linux服务支持(修改make.sh文件）
去掉注释# WITH_HTTPD=1
去掉注释# WITH_LINUX_SERVICE=1
修改安装目录：TARGET_PREFIX=/usr/local/fastdfs

[root@vanedev2 ~] ./make.sh C_INCLUDE_PATH=/usr/local/libevent/include LIBRARY_PATH=/usr/local/libevent/lib
[root@vanedev2 ~] ./make.sh install

修改tracker.conf文件,修改如下

1
2
3

base_path=/usr/local/fastdfs/
http.server_port= 8090 # 指定端口
#include http.conf # HTTP支持

修改storage.conf文件,修改如下：

#可以自定义，但必须存在此目录，用于存储storage相关的log、group内的相关信息
group_name=lxsym #自定义组
base_path=/usr/local//fastdfs #安装路径
store_path0=/data/fastdfs #数据存储路径(可以指定多个)
tracker_server=192.168.1.19:22122 #跟踪器IP及端口
http.server_port= 8888 # 指定端口
#include http.conf # HTTP支持
修改client.conf文件,修改如下
http.tracker_server_port=8080 # 指定端口

启动服务：

[root@vanedev2 ~] /usr/local/fastdfs/bin/fdfs_trackerd /etc/fdfs/tracker.conf
[root@vanedev2 ~] /usr/local/fastdfs/bin/fdfs_storaged /etc/fdfs/storage.conf

上传文件测试：

[root@vanedev2 bin]# /usr/local/fastdfs/bin/fdfs_test /etc/fdfs/client.conf upload 1.txt

This is FastDFS client test program v3.11
