【架构设计】分布式文件系统 FastDFS的原理和安装使用

fastDFS需要安装libevent比较新的版本，将本机的比较低的版本卸载了。
 
rpm -qa libevent
libevent-1.4.13-1.el6.x86_64
rpm -e --nodeps libevent
安装一个最新稳定版
 
wget https://github.com/downloads/libevent/libevent/libevent-2.0.18-stable.tar.gz
tar zxvf libevent-2.0.18-stable.tar.gz
cd libevent-2.0.18-stable
./configure
make && make install
为libevent创建软链接到/lib库下，64位系统对应/lib64
 
ln -s /usr/local/lib/libevent* /lib/
ln -s /usr/local/lib/libevent* /lib64/

wget http://fastdfs.googlecode.com/files/FastDFS_v3.06.tar.gz
tar zxvf FastDFS_v3.06.tar.gz
cd FastDFS
./make.sh
./make.sh install

环境：
tracker server
192.168.1.5
storage server
192.168.1.51
192.168.1.52
 
1、配置并启动 tracker server
①配置 tracker.conf
 
mkdir /data/fastdfs
vim /etc/fdfs/tracker.conf
base_path=/data/fastdfs
②启动 tracker
 
/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
③开机启动
 
vim /etc/rc.local
/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
2、配置并启动 storage server
①配置 tracker.conf
 
mkdir /data/fastdfs
mkdir /data/images
vim /etc/fdfs/storage.conf
base_path=/data/fastdfs
store_path0=/data/images
tracker_server=192.168.1.5:22122
②启动 tracker
 
/usr/local/bin/fdfs_storage /etc/fdfs/storage.conf
③开机启动
 
vim /etc/rc.local
/usr/local/bin/fdfs_storage /etc/fdfs/storage.conf
3、为storage节点安装fastdfs-nginx-module模块
①安装模块
安装Nginx详见：
需重新编译Nginx
 
wget http://fastdfs.googlecode.com/files/fastdfs-nginx-module_v1.10.tar.gz
tar zxvf fastdfs-nginx-module_v1.10.tar.gz
wget http://nginx.org/download/nginx-1.2.0.tar.gz
tar zxvf nginx-1.2.0.tar.gz
cd nginx-1.2.0
./configure --prefix=/usr/local/nginx --add-module=../fastdfs-nginx-module/src
make && make install
cd ..
②配置
编辑nginx.conf
 
vim /usr/local/nginx/conf/nginx.conf
server {
    listen       80;
    server_name  localhost;
 
    location /M00 {
        alias /data/images/data;
        ngx_fastdfs_module;
    }
    ......
}
给 storage 的存储目录做一个软连接
 
ln -s /data/images/data/ /data/images/data/M00
拷贝mod_fastdfs.conf 到 /etc/fdfs/
 
cp fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
vim /etc/fdfs/mod_fastdfs.conf
base_path=/data/fastdfs
tracker_server=192.168.1.5:22122
store_path0=/data/images
启动nginx
 
/usr/local/nginx/sbin/nginx

1、上传文件
FastDFS安装包中，自带了客户端程序，通过程序可以进行文件上传。在使用这个客户端程序之前，首先需要配置client.conf，然后再进行文件上传及下载。
在tracker上修改客户端配置文件client.conf
 
vim /etc/fdfs/client.conf
base_path=/data/fastdfs
tracker_server=192.168.1.5:22122
vim a.html
This Is FastDFS Test.
上传文件
 
/usr/local/bin/fdfs_test /etc/fdfs/client.conf upload a.html
This is FastDFS client test program v3.06
