本文介绍了tfs 2.2.16版本在centos linux 6.3 64位系统上单台nameserver和dataserver环境的配置过程。
在Tfs体系架构中把服务器角色分配为nameserver, dataserver, rcs server,meta server等，其中nameserver和data server是核心，nameserver在TFS中类似DNS服务器的作用，客户端通过向nameserver发起请求，查询dataserver的相关信息，然后在dataserver上进行添加，删除，更新等文件操作。更详细的介绍请参考官方文档！http://tfs.taobao.org
环境介绍:
Tfs nameserver: 192.168.1.225/24
Tfs dataserver: 192.168.1.227/24
一：nameserver配置文件, 各项配置参数的具体含义可参考注释或官方文档说明。

三: 启动nameserver

|
# /usr/local/tfs/scripts/tfs start_ns
nameserver is up SUCCESSFULLY pid: 10609
# netstat -ntpl |grep name
|
四: 启动dataserver
|

3
|
# cd /usr/local/tfs/scripts/
# ./stfs format 1-3 //这里的format 1-3指格式化第一到第三个挂载点
# df -h |grep data

|
# ./tfs start_ds 1-3
dataserver 1 is up SUCCESSFULLY pid: 28821
dataserver 2 is up SUCCESSFULLY pid: 28847
dataserver 3 is up SUCCESSFULLY pid: 28866
# netstat -ntpl |grep data
|
五:连接测试
|

|
# /usr/local/tfs/bin/ssm -s 192.168.1.225:8108 -i show server
# /usr/local/tfs/bin/ssm -s 192.168.1.225:8108 -i show machine
|
六:写入测试，写入后会吐出几个关键的信息，block_id,file_id和file_name
