图片服务器(FastDFS)的搭建

1.1 什么是FastDFS

FastDFS是用c语言编写的一款开源的分布式文件系统。FastDFS为互联网量身定制，充分考虑了冗余备份、负载均衡、线性扩容等机制，并注重高可用、高性能等指标，使用FastDFS很容易搭建一套高性能的文件服务器集群提供文件上传、下载等服务。

1.2 文件上传流程

1.3 文件下载流程

1.4 上传文件的文件名

客户端上传文件后存储服务器将文件ID返回给客户端，此文件ID用于以后访问该文件的索引信息。文件索引信息包括：组名，虚拟磁盘路径，数据两级目录，文件名。

n 组名：文件上传后所在的storage组名称，在文件上传成功后有storage服务器返回，需要客户端自行保存。

n 虚拟磁盘路径：storage配置的虚拟路径，与磁盘选项store_path*对应。如果配置了store_path0则是M00，如果配置了store_path1则是M01，以此类推。

n 数据两级目录：storage服务器在每个虚拟磁盘路径下创建的两级目录，用于存储数据文件。

文件名：与文件上传时不同。是由存储服务器根据特定信息生成，文件名包含：源存储服务器IP地址、文件创建时间戳、文件大小、随机数和文件拓展名等信息。

1.5 FastDFS搭建

可以使用一台虚拟机来模拟，只有一个Tracker、一个Storage服务。

配置nginx访问图片。

1.5.1 搭建步骤

第一步：把fastDFS都上传到linux系统。

第二步：安装FastDFS之前，先安装libevent工具包。

yum -y install libevent

第三步：安装libfastcommonV1.0.7工具包。

1、解压缩

2、./make.sh

3、./make.sh install

4、把/usr/lib64/libfastcommon.so文件向/usr/lib/下复制一份

第四步：安装Tracker服务。

1、解压缩

2、./make.sh

3、./make.sh install

安装后在/usr/bin/目录下有以fdfs开头的文件都是编译出来的。

配置文件都放到/etc/fdfs文件夹

4、把/root/FastDFS/conf目录下的所有的配置文件都复制到/etc/fdfs下。

5、配置tracker服务。修改/root/FastDFS/conf/tracker.conf文件。

6、启动tracker。/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf

重启使用命令：/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart

第五步：安装storage服务。

1、如果是在不同的服务器安装，第四步的1~4需要重新执行。

2、配置storage服务。修改/root/FastDFS/conf/storage.conf文件

 

3、启动storage服务。

/usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart

第六步：测试服务。

1、修改配置文件/etc/fdfs/client.conf

2、测试

/usr/bin/fdfs_test /etc/fdfs/client.conf upload anti-steal.jpg

第七步：搭建nginx提供http服务。

可以使用官方提供的nginx插件。要使用nginx插件需要重新编译。

fastdfs-nginx-module_v1.16.tar.gz

1、解压插件压缩包

2、修改/root/fastdfs-nginx-module/src/config文件，把其中的local去掉。

 

3、对nginx重新config

./configure \

--prefix=/usr/local/nginx \

--pid-path=/var/run/nginx/nginx.pid \

--lock-path=/var/lock/nginx.lock \

--error-log-path=/var/log/nginx/error.log \

--http-log-path=/var/log/nginx/access.log \

--with-http_gzip_static_module \

--http-client-body-temp-path=/var/temp/nginx/client \

--http-proxy-temp-path=/var/temp/nginx/proxy \

--http-fastcgi-temp-path=/var/temp/nginx/fastcgi \

--http-uwsgi-temp-path=/var/temp/nginx/uwsgi \

--http-scgi-temp-path=/var/temp/nginx/scgi \

--add-module=/root/fastdfs-nginx-module/src

2、make

3、make install

4、把/root/fastdfs-nginx-module/src/mod_fastdfs.conf文件复制到/etc/fdfs目录下。编辑：

 

 

1、nginx的配置

在nginx的配置文件中添加一个Server：

server {

        listen       80;

        server_name  192.168.101.3;

 

        location /group1/M00/{

                #root /home/FastDFS/fdfs_storage/data;

                ngx_fastdfs_module;

        }

}

2、将libfdfsclient.so拷贝至/usr/lib下

cp /usr/lib64/libfdfsclient.so /usr/lib/

3、启动nginx

nginx 400 Bad Request，详情可参考以下链接:

[root@web2 ~]# vim /etc/fdfs/mod_fastdfs.conf 
url_have_group_name = false 改为 true      #关于啥意思，配置文件中有解释
