	1》安装
		yum  localinstall ./* #安装软件
		cd /etc/fdfs/ ;ls  #发现有很多示例
		anti-steal.jpg  client.conf.sample  http.conf  mime.types  storage.conf.sample  storage_ids.conf.sample  tracker.conf.sample
	2》在centos7.1节点上配置tracker节点
		cd /etc/fdfs/
		cp tracker.conf.sample tracker.conf.sample.bak
		mv tracker.conf.sample tracker.conf
		vim tracker.conf
			base_path=/app/fastdfs/tracker #设置tracker的存储路径
			store_group=shen #设置一个存储组，注意不能带任何符号，不然会出现端口启用不了
		mkdir -pv /app/fastdfs/tracker #在centos7.1节点上创建tracker的数据目录
		mkdir /app/fastdfs/storage #创建storage的存储目录
	3》在centos7.2和7.3节点上只创建storage的存储目录
		mkdir /app/fastdfs/storage -pv
	4》在三个节点上对storage进行配置
		cd /etc/fdfs/
		cp storage.conf.sample storage.conf.sample.bak
		mv storage.conf.sample storage.conf
		vim storage.conf
			group_name=shen
			base_path=/app/fastdfs/storage #storage的基础路径，用于存储日志等
			store_path0=/app/fastdfs/storage #storage的存储路径，这个必须设置，可以和上面的在同一个目录下
			tracker_server=192.168.213.251:22122 #指明tracker主机
		在centos7.1节点上启动tracker和storage服务
			systemctl start fdfs_trackerd
			systemctl start fdfs_storaged
		ss  -nltp  #发现tracker监听的端口是22122，storage监听的端口是23000
		在centos7.2和7.3节点上启动storage服务
			systemctl start fdfs_storaged
			ss -nlt #发现23000端口已经打开
	5》配置客户端的配置文件，在centos7.1节点设置
		cd /etc/fdfs/ ;ls
			anti-steal.jpg      http.conf   storage.conf             storage_ids.conf.sample  tracker.conf.sample.bak
			client.conf.sample  mime.types  storage.conf.sample.bak  tracker.conf
		cp client.conf.sample client.conf.bak
		mv client.conf.bak client.conf
		vim client.conf
			base_path=/app/fastdfs/tracker
			tracker_server=192.168.213.251:22122
		fdfs_monitor /etc/fdfs/client.conf #可以查看存储节点的状态信息
	6》文件的上传和查看操作
		cd /etc/fdfs/ ;ls
			anti-steal.jpg  client.conf.sample  mime.types    storage.conf.sample.bak  tracker.conf
			client.conf     http.conf           storage.conf  storage_ids.conf.sample  tracker.conf.sample.bak
		fdfs_upload_file /etc/fdfs/client.conf /app/flower.jpg #注意上传时要指明客户端的配置文件
			shen/M00/00/00/wKjV-1o01sOAHG17AAAN9EUC0YY902.jpg
		cd /app/fastdfs/storage/data/00/00/  ;ls    #每个节点的此目录下都有这个文件，说明同步成功
			wKjV-1o01sOAHG17AAAN9EUC0YY902.jpg
		fdfs_file_info /etc/fdfs/client.conf shen/M00/00/00/wKjV-1o01sOAHG17AAAN9EUC0YY902.jpg #查看文件
			source storage id: 0
			source ip address: 192.168.213.251
			file create timestamp: 2017-12-16 16:18:11
			file size: 3572
			file crc32: 1157812614 (0x4502D186)
		fdfs_test /etc/fdfs/client.conf upload /root/anaconda-ks.cfg  #上传测试
		fdfs_upload_file /etc/fdfs/client.conf  /root/anaconda-ks.cfg #上传文件
			magedu/M00/00/00/rBIVB1oylFSADeGrAAAHXGXWizs514.cfg
		fdfs_download_file /etc/fdfs/client.conf magedu/M00/00/00/rBIVB1oylFSADeGrAAAHXGXWizs514.cfg #下载文件到当前目录

FastDFS实现nginx代理

	1》在centos7.1节点安装nginx的相关包，注意要安装nginx-1.10版本，不然可能没有ngx_fastdfs_module模块，如果之前已经安装nginx及相应的依赖包，最好先卸载了
		cd /app
		ls #将nginx-1.10.2版本的nginx及相应的依赖包下载到本地
			nginx-1.10.2-1.el7.centos.x86_64.rpm #注意版本要统一都是1.10.2的版本
			nginx-all-modules-1.10.2-1.el7.centos.noarch.rpm #下面这些都是nginx的依赖包
			nginx-filesystem-1.10.2-1.el7.centos.noarch.rpm
			nginx-mod-http-geoip-1.10.2-1.el7.centos.x86_64.rpm
			nginx-mod-http-image-filter-1.10.2-1.el7.centos.x86_64.rpm
			nginx-mod-http-perl-1.10.2-1.el7.centos.x86_64.rpm
			nginx-mod-http-xslt-filter-1.10.2-1.el7.centos.x86_64.rpm
				nginx-mod-mail-1.10.2-1.el7.centos.x86_64.rpm
			nginx-mod-stream-1.10.2-1.el7.centos.x86_64.rpm
		yum install ./nginx*
	2》修改nginx的配置文件
		vim /etc/nginx/nginx.conf
			location /magedu/M00 { #表示匹配以 /magdu/M00开头的uri
			          root /app/fastdfs/storage; #指明数据存储的目录
			            ngx_fastdfs_module;
			}
		nginx
			ngx_http_fastdfs_set pid=14594
		ss -nlt
	3》修改fastdfs_module配置文件的设置
		vim /etc/fdfs/mod_fastdfs.conf
			url_have_group_name = true #是否允许访问的url中包含组名
			store_path0=/app/fastdfs/storage #指明storage节点存储数据的目录
			tracker_server=172.18.21.107:22122 #指明tracker节点
			group_name=magedu #指明组名
	4》测试
		fdfs_upload_file /etc/fdfs/client.conf /app/sunset.jpg #上传一个文件
			magedu/M00/00/00/rBIVa1ozvNWAJLHkAAAKwLGLsZc035.jpg
			访问如下网站就可以看到存储的图片
