FastDFS是一个开源的轻量级分布式文件系统，由跟踪服务器（tracker server）、存储服务器（storage server）和客户端（client）三个部分组成，主要解决了海量数据存储问题，特别适合以中小文件（建议范围：4KB < file_size <500MB）为载体的在线服务。在生成环境FastDFS一般都是用集群配置，以提高FastDFS的可用性，并发能力。
部署架构：
环境IP地址(关闭所有环境的防火墙)：
Tracker 192.168.18.178
Group 1：
S1：192.168.110.71
S2：192.168.110.91
Group 2：
S3：192.168.100.90
S4：192.168.100.194
注：Tracker可以部署多台，提供负载，这里资源有限，就部署一台。
由于需要安装nginx，每台机器都安装依赖：
yum -y install zlib pcre pcre-devel zlib-devel
所用的安装软件下载：http://download.csdn.net/detail/tianwei7518/8745279
一、安装tracker
1.安装依赖libfastcommon
unzip libfastcommon-master.zip
cd libfastcommon
./make.sh
./make.sh install
2.安装FastDFS
unzip fastdfs.zip
cd fastdfs
./make.sh
./make.sh install
默认安装目录：/usr/bin
将原安装文件夹下的配置文件复制到/etc/fdfs目下：cp ./conf/* /etc/fdfs/
3.配置
编辑配置文件目录下的tracker.conf
一般只需改动以下几个参数即可：
disabled=false #启用配置文件
port=22122 #设置tracker的端口号
base_path=/home/fastdfs #设置tracker的数据文件和日志目录（需预先创建）
http.server_port=8080 #设置http端口号
4.启动
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
二、安装tracker代理nginx
在tracker上安装的nginx主要为了提供http访问的反向代理、负载均衡以及缓存服务。 1.安装nginx tar -zxvf nginx-1.8.0.tar.gz
tar -zxvf ngx_cache_purge-2.3.tar.gz
cd nginx-1.8.0
./configure --prefix=/usr/local/nginx --add-module=/root/ngx_cache_purge-2.3
make
make install
如果提示错误，可能缺少依赖的软件包，需先安装依赖包，再次运行./configure
nginx以及nginx cache purge插件模块安装完成，安装目录/usr/local/nginx
2.配置nginx 1

}
}
}
|
创建缓存目录：/var/cache/nginx/proxy_cache/tmp 3.启动
/usr/local/nginx/sbin/nginx
三、安装storage
1.安装
参考安装tracker前2步骤。
2.配置
编辑配置文件目录下的storage.conf
只需改动以下几个参数即可：
disabled=false #启用配置文件
group_name=group1 #组名，根据实际情况修改
port=23000 #设置storage的端口号
base_path=/home/fastdfs #设置storage的日志目录（需预先创建）
store_path_count=1 #存储路径个数，需要和store_path个数匹配
store_path0=/home/fastdfs#存储路径
tracker_server=192.168.18.178:22122#tracker服务器的IP地址和端口号
http.server_port=8080 #设置http端口号
创建目录mkdir /home/fastdfs
3.运行
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf start
另外：
分别在其他机器上全部安装storage并确认运行正常。注意配置文件中group名参数需要根据实际情况调整：
group1：192.168.110.71，192.168.110.91
group2：192.168.100.90，192.168.100.194
另外每个group中所有storage的端口号必须一致。
四、在storage上安装nginx
在storage上安装的nginx主要为了提供http的访问服务，同时解决group中storage服务器的同步延迟问题。
1.解压fastdfs-nginx-module插件
unzip fastdfs-nginx-module.zip
2.安装nginx
tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
./configure --prefix=/usr/local/nginx --add-module=../fastdfs-nginx-module/src
make
make install
安装目录：/usr/local/nginx
若安装报错：[emerg] 13513#0: eventfd() failed (38: Function not implemented)
原因是：编译时带了--with-file-aio模块，这个要Linux 2.6.22以后内核才支持．服务器是2.6.18。也可以下载低版本的nginx版本
3.配置
1）配置FastDFS的nginx插件
将FastDFS的nginx插件模块的配置文件copy到FastDFS配置文件目录
fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
编辑/etc/fdfs配置文件目录下的mod_fastdfs.conf，设置storage信息并保存。
一般只需改动以下几个参数即可：
base_path=/home/fastdfs #保存日志目录
tracker_server=192.168.18.178:22122 #tracker服务器的IP地址以及端口号
storage_server_port=23000#storage服务器的端口号
group_name=group1#当前服务器的group名
url_have_group_name = true #文件url中是否有group名
store_path_count=1 #存储路径个数，需要和store_path个数匹配
store_path0=/home/fastdfs #存储路径
http.need_find_content_type=true#从文件扩展名查找文件类型（nginx时为true）
group_count = 2 #设置组的个数
在末尾增加2个组的具体信息：
[group1]
group_name=group1
storage_server_port=23000
store_path_count=1
store_path0=/home/fastdfs
[group2]
group_name=group2
storage_server_port=23000
store_path_count=1
store_path0=/home/fastdfs
建立M00至存储目录的符号连接：
ln -s /home/fastdfs/data /home/fastdfs/data/M00
2）配置nginx
vi nginx.conf
user root;
location ~/group[1-3]/M00 {
root /home/fastdfs/data;
ngx_fastdfs_module;
}
4.启动
/usr/local/nginx/sbin/nginx
另外：
分别在其他机器storage上全部安装nginx并确认运行正常。注意配置文件中group名参数需要根据实际情况调整：
group1：192.168.110.71，192.168.110.91
group2：192.168.100.90，192.168.100.194
另外nginx的端口号8090。
至此所有配置完毕。
四、测试
配置/etc/fdfs/client.conf
base_path=/home/fastdfs #日志存放路径
tracker_server=192.168.18.43:22122 #tracker服务器IP地址和端口号
http.tracker_server_port=8080 #tracker服务器的http端口号
通过fdfs_upload_file上传一个文件到FastDFS，程序会自动返回文件的URL，
#fdfs_upload_file /etc/fdfs/client.conf 40-15052PZK5.jpg
group1/M00/00/00/wKhuR1Vmh_2ADmdfAAF1dmVtk4w934.jpg
然后使用浏览器访问，访问正常
http://192.168.18.43/group1/M00/ ... fAAF1dmVtk4w934.jpg
注：可以使用fdfs_monitor查看tracker和所有group的运行情况
