简介
- 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。FastDFS服务端有两个角色：跟踪器（tracker）和存储节点（storage）。跟踪器主要做调度工作，在访问上起负载均衡的作用。
-
存储节点存储文件，完成文件管理的所有功能：就是这样的存储、同步和提供存取接口，FastDFS同时对文件的metadata进行管理。所谓文件的meta data就是文件的相关属性，以键值对（key valuepair）方式表示，如：width=1024，其中的key为width，value为1024。文件metadata是文件属性列表，可以包含多个键值对。
拓扑图
部署
- 环境安装
yum install -y zlib zlib-devel pcre pcre-devel gcc gcc-c++ openssl openssl-devel libevent libevent-devel perl unzip 或者 yum groupinstall 'Development tools' -y
- 下载软件包
下载Libfastcommon
wget https://github.com/happyfish100/libfastcommon/archive/master.zip
下载FastDFS
wget https://github.com/happyfish100/fastdfs/archive/V5.05.tar.gz
下载FastDFS-Nginx模块
wget http://jaist.dl.sourceforge.net/project/fastdfs/FastDFS%20Nginx%20Module%20Source%20Code/fastdfs-nginx-module_v1.16.tar.gz
下载Nginx
wget http://nginx.org/download/nginx-1.8.0.tar.gz
- 创建数据储存目录
#在tracker_server上创建tracker目录；在storage_server上创建storage目录
mkdir -p /data/fastdfs/{storage,tracker}
- 安装Libfastcommon
Tracker-server和storage-server都需要安装
unzip libfastcommon-master.zip
cd libfastcommon-master
./make.sh
./make.sh install
ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so
ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so
ln -s /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so
- 安装FastDFS
解压、编译安装FastDFS
tar -xf FastDFS_v5.08.tar.gz
cd FastDFS
sh make.sh && sh make.sh install
cp -pa conf/*.conf /etc/fdfs/
cp -pa conf/mime.types /etc/fdfs/
cd /etc/fdfs/
rm -rf *.sample
chown -R nobody.nobody /data/fastdfs
chown -R nobody.nobody /etc/fdfs
注：这里赋予nobody账号权限是因为nginx用nobody用户启动

- 安装Nginx和Fastdfs-Nginx模块
tar -zxf fastdfs-nginx-module_v1.16.tar.gz && tar -zxf nginx-1.10.1.tar.gz
cd fastdfs-nginx-module/src/
cp -r mod_fastdfs.conf /etc/fdfs/
vim /soft/FastDFS/fastdfs-nginx-module/src/config
#修改config文件如下
更改前：“CORE_INCS="$CORE_INCS /usr/local/include/fastdfs /usr/local/include/fastcommon/"
CORE_LIBS="$CORE_LIBS -L/usr/local/lib -lfastcommon -lfdfsclient"”
更改后：“CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/local/include/fastcommon/"
CORE_LIBS="$CORE_LIBS -L/usr/lib64 -lfastcommon -lfdfsclient"”

ln -sv /usr/incloud/fastcommon /usr/local/incloud/fastcommon
ln -sv /usr/incloud/fastdfs /usr/local/incloud/fastdfs
ln -sv /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
#安装nginx
cd nginx-1.10.1

- 启动进程，并查看端口
/etc/init.d/fdfs_trackerd start
/etc/init.d/fdfs_storaged start
Starting FastDFS storage server:
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
#查看进程
netstat -npl|grep -E "nginx|fdfs"
tcp 0 0 0.0.0.0:23000 0.0.0.0:* LISTEN 27454/fdfs_storaged
tcp 0 0 10.12.8.42:22122 0.0.0.0:* LISTEN 14179/fdfs_trackerd
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 14201/nginx
ps:注意事情：Centos 7.1版本中trackerd和storaged启动失败时，做以下操作
ln -s /usr/bin/fdfs_trackerd /usr/local/bin
ln -s /usr/bin/fdfs_storaged /usr/local/bin
ln -s /usr/bin/stop.sh /usr/local/bin
ln -s /usr/bin/restart.sh /usr/local/bin
- 测试
echo 'test fastDFS!!!' > test.htm
vim /etc/fdfs/client.conf
添加tracker_server地址
fdfs_test /etc/fdfs/client.conf upload test.html
This is FastDFS client test program v5.08
