fastdfs 简介
FastDFS是一个国产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。

安装文件：

FastDFS 5.x 取消了对 libevent 的依赖，添加了对 libfastcommon 的依赖。
本部署说明用到的软件版本：

libfastcommon v1.13

FastDFS v5.08

fastdfs-nginx-module v1.17

fastdfs安装配置：

创建用户与组

# groupadd fdfs

# useradd fdfs -g fdfs

解压、安装

在每一台tracker和storage服务器上执行

# tar xzvf FastDFS_v5.08.tar.gz

#cd FastDFS/

#./make.sh

#./make.sh install

# yum install -y gcc perl   # 安装依赖的软件包

#cd ~/fdfs/libfastcommon && ./make.sh && ./make.sh install

# cd ~/fdfs/fastdfs && ./make.sh && ./make.sh install

安装完成后，所有可执行文件在目录/usr/bin下，以fdfs_开头：

# ls /usr/bin/fdfs*

fdfs_monitor   fdfs_trackerd  fdfs_storaged

配置文件在目录/etc/fdfs下

client.conf.sample  storage.conf.sample  tracker.conf.sample

FastDFS配置

配置Tracker跟踪器

开放tracker监听端口访问

firewall-cmd --zone=public --add-port=22122/tcp --permanent
firewall-cmd --reload

vim /etc/sysconfig/iptables

service iptables restart

修改配置文件

mkdir -p /data/fastdfs
cd /etc/fdfs
cp tracker.conf.sample tracker.conf
cp /root/fdfs/fastdfs/conf/http.conf .
cp /root/fdfs/fastdfs/conf/mime.types .

启动tracker：fdfs_trackerd /etc/fdfs/tracker.conf

启动storage：fdfs_storaged /etc/fdfs/storage.conf

设置开机自启动

cat /data/fastdfs/logs/trackerd.log

vim /etc/rc.local

运行fdfs_monitor查看storage服务器是否已经登记到tracker服务器

fdfs_monitor /etc/fdfs/storage.conf

自启动

su - fastdfs -c “/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start”

su - fastdfs -c “/usr/bin/fdfs_storaged /etc/fdfs/storage.conf start”

 待确定

注意，上述安装的路径在/usr/lib64/，但是FastDFS主程序设置的lib目录是/usr/local/lib，所以需要创建软连接如下:

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
