FastDFS分布式文件系统的安装及配置
-
整体网络配置
Tracker Server 192.168.127.11 /home/fastdfs/tracker 端口:22122 Storage1 Server 192.168.127.12 group1 /home/fastdfs/fdfs_storage 端口:23000 Storage2 -Server1(源) 192.168.127.13 group2 /home/fastdfs/fdfs_storage 端口:23000 Storage2 -Server2 192.168.127.14 group2 /home/fastdfs/fdfs_storage 端口:23000 注意: 1.Storage2 同组的fastdfs服务的端口必须一致: port=23000 2.如果开启http 端口 则Storage2 同组的http端口必须一致: http.server_port 3.一台服务器可以装多个组但不能装同组的多个Storage,日志会报错误 4.无论你是否启动内部绑定的的http服务器,都要安装libevent包,fastdfs内部调用libevent的处理机制

#软件安装包存储: /usr/local/src /etc/fdfs/* #tracker,storage ·· 配置文件所在目录 #基本目录列表: /home/fastdfs/tracker #创建tracker目录保存运行日志 /home/fastdfs/fdfs_storage #创建Storage目录保存运行日志及其data数据 mkdir -p /home/fastdfs/tracker; mkdir -p /home/fastdfs/fdfs_storage; 为方便查找目录,设置变量 # vi .bashrc alias worksrc='cd /usr/local/src;ls' alias worktracker='cd /home/fastdfs/tracker;ls' alias workstorage='cd /home/fastdfs/fdfs_storage;ls' #track启动 重启 停止 alias trackstart='/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf;netstat -tunl '; alias trackrestart='/usr/local/bin/restart.sh /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf;netstat -tunl'; alias trackstop='/usr/local/bin/stop.sh /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf;netstat -tunl'; #storaged 启动 重启 停止 alias storagedstart='/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf;netstat -tunl '; alias storagedrestart='/usr/local/bin/restart.sh /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf;netstat -tunl'; alias storagedstop='/usr/local/bin/stop.sh /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf;netstat -tunl'; 配置生效 # source .bashrc

安装libevent 和 FastDFS
-
首先安装libevent,因为 FastDFS 在编译源程序时,需要用到libevent一些依赖文件,否则编译 FastDFS 会出错
##卸载系统自带libevent,自带版本过低,安装fastdfs会出错 rpm -qa|grep libevent;yum remove libevent* #下载安装libevent worksrc; wget http://cloud.github.com/downloads/libevent/libevent/libevent-2.0.19-stable.tar.gz; tar -zxvf libevent-2.0.19-stable.tar.gz; cd libevent-2.0.19-stable; make clean; ./configure --prefix=/usr/local/libevent 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/libevent/lib/libevent-2.0.so.5 /usr/lib/libevent-2.0.so.5 ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5 命令汇总:worksrc;wget http://cloud.github.com/downloads/libevent/libevent/libevent-2.0.19-stable.tar.gz;tar -zxvf libevent-2.0.19-stable.tar.gz;cd libevent-2.0.19-stable;make clean;./configure --prefix=/usr/local/libevent;make && make install;cd ../

安装FastDFS的步骤
wget http://fastdfs.googlecode.com/files/FastDFS_v3.11.tar.gz tar -zxvf FastDFS_v3.11.tar.gz cd FastDFS #因为不启用内置http服务,所以不需要修改make.sh和开启端口 ./make.sh C_INCLUDE_PATH=/usr/local/libevent/include LIBRARY_PATH=/usr/local/libevent/lib ./make.sh install

测试下载文件
在浏览器中,输入上图中的url地址, tracker server会自动重定向到存储文件的storage server,文件下载成功。至此,已经成功搭建了FastDFS,编写你自己的client来进行访问吧:展示aa.txt文本数据
