对于拥有大量图片和小文件的站点,如电子商务网站,用tfs是非常理想的,淘宝就是NB.

四台服务器，系统都为Centos 5.6

一、基础环境的设置（只需在dataserver两台服务器上配置）

1.加载ext4模块，让系统支持ext4文件系统

modprobe ext4

2.安装ext4格式工具

yum –y install  e4fsprogs e4fsprogs-devel

3.建立数据目录

mkdir /home/disk1

mkdir /home/disk2

mkdir /home/disk3

4.格式硬盘

mkfs.ext4 /dev/sdb

mkfs.ext4 /dev/sdc

mkfs.ext4 /dev/sdd

5.挂载硬盘

mount /dev/sdb /home/disk1

mount /dev/sdc /home/disk2

mount /dev/sdd /home/disk3

6.查看挂载分区

二、文档配置（安装略…可参考官网http://code.taobao.org/p/tfs/wiki/index/）

5.TFS的Dataserver(192.168.2.243)配置...略和2.243相似，不能写，写不下了。

三、服务启动

1．启动tfs（192.168.2.240）的nameserver

/usr/local/tfs/scripts/tfs  start_ns

2．启动tfs（192.168.2.241）的nameserver

/usr/local/tfs/scripts/tfs  start_ns

3．启动tfs（192.168.2.242）的dataserver

/usr/local/tfs/scripts/tfs admin_ns

3.1查看到服务端的连接

3.2查看dataserver下的块

4.启动tfs（192.168.2.243）的dataserver

/usr/local/tfs/scripts/tfs admin_ns

四、测试

用tfstool工具连接到服务端上传图片

看到上传的图片已经保存成功
