TFS使用tb-common-utils软件包，tb-common-utils包含淘宝使用的基础系统库tbsys和网络库tbnet两个组件；安装tb-common-utils前需要设置环境变量TBLIB_ROOT，tbsys和tbnet将会被安装TBLIB_ROOT对应的路径（必须是绝对路径）下，TFS会在这个路径下查找tbsys、tbnet头文件和库。

设置TBLIB_ROOT环境变量
export TBLIB_ROOT=/usr/local/tb/lib

export LD_LIBRARY_PATH=/usr/local/gcc-4.1.2/lib

export CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/home/tb-common-utils_18/tbsys/src:/home/tb-common-utils_18/tbnet/src
export echo=echo
在~/.bash_profile文件中加入，export TBLIB_ROOT=/usr/local/tb , 然后执行source ~/.bash_profile
# cd tb-common-utils

#cd tbnet

#./configure

#cd tbsys

#./configure

# sh build.sh

# cd tfs
# sh build.sh init
# ./configure --prefix=/usr/local/tfs --with-release
# make
# make install

报错解决第一步，高版本的gcc4.4.7，tfs一般要用低版本的gcc4.1.2，但是高版本呢的也可以解决报错问题，首先
用# find ./ -name Makefile | xargs sed -i 's/-Werror//'
第二步
# vi ./src/common/session_util.h
第一行添加如下：
#include <stdint.h>
第三步
# vi ./src/name_meta_server/meta_server_service.cpp
1584行修改如下：
char* pos = (char *) strstr(sub_dir, parents_dir);
然后再make make install

一、安装依赖的软件包:
1、automake TFS基于automake工具构建:

yum install automake.noarch

2、libtool automake需要使用libtool:

yum install libtool

3、realine 用于命令行编辑的库：

yum install readline-devel

4、libz-devel 用于数据压缩/解压缩：

yum install zlib-devel

5、uuid-devel 用于生成全局唯一ID：

yum install e2fsprogs-devel
yum install libuuid-devel

6、tcmalloc google的内存管理库(由玩googl被封，那就暂且跳过吧，可选)

二、安装tb-common-utils
TFS使用tb-common-utils软件包，tb-common-utils包含淘宝使用的基础系统库tbsys和网络库tbnet两个组件；安装tb-common-utils前需要设置环境变量TBLIB_ROOT，tbsys和tbnet将会被安装TBLIB_ROOT对应的路径（必须是绝对路径）下，TFS会在这个路径下查找tbsys、tbnet头文件和库。
设置TBLIB_ROOT环境变量：
1、在~/.bash_profile文件中加入，export TBLIB_ROOT=path_to_tbutil , 然后执行source：

~/.bash_profile

vi ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
	. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
export TBLIB_ROOT=/usr/local/tb-common-utils

# source ~/.bash_profile

2、下载源码：

# svn co -r 18 http://code.taobao.org/svn/tb-common-utils/trunk tb-common-utils

注意：这里不要checkout最新版本，version18以后的修改导致部分接口不能前向兼容

# cd /usr/local/tb-common-utils/
# sh build.sh

checking for C++ compiler default output file name... 
configure: error: in `/usr/local/tb-common-utils/tbnet':
configure: error: C++ compiler cannot create executables
See `config.log' for more details.
make: *** No targets specified and no makefile found.  Stop.
make: *** No rule to make target `install'.  Stop.

这个错误是因为缺少gcc-c++：

yum install gcc-c++

如果一切顺利，tb-common-utils已经安装成功到$TBLIB_ROOT路径下；

三、安装TFS
TFS开源用户大都只使用TFS的基本功能，所以这个版本我们默认只编译TFS的nameserver，dataserver，client和tool，以去除对mysql的依赖，需要使用到rcserver（全局资源管理服务），metaserver(TFS自定义文件名服务）的用户请自行编译安装这两个服务。
下载源码并安装：

# svn co http://code.taobao.org/svn/tfs/branches/dev_for_outer_users tfs
# cd tfs/
# sh build.sh init
+ aclocal
+ libtoolize --force --copy
libtoolize: putting auxiliary files in `.'.
libtoolize: copying file `./ltmain.sh'
libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and
libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree.
libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
libtoolize: `AC_PROG_RANLIB' is rendered obsolete by `LT_INIT'
+ autoconf --force
+ automake --foreign --copy --add-missing
configure.ac:16: installing `./config.guess'
configure.ac:16: installing `./config.sub'
configure.ac:8: installing `./install-sh'
configure.ac:8: installing `./missing'
src/adminserver/Makefile.am: installing `./depcomp'
# ./configure --prefix=/usr/local/taobaoFS --with-release

checking for tc_cfree in -ltcmalloc... no
configure: error: in `/usr/local/tfs/tfs':
configure: error: tcmalloc link failed (--without-tcmalloc to disable)
See `config.log' for more details.

注意，这里报错了，是因为之前我们没有安装tcmalloc，所以这里要改一下编译条件：

# ./configure --prefix=/usr/local/taobaoFS --with-release --without-tcmalloc
# make
# make install

–prefix 指定tfs安装路径，默认会被安装到~/tfs_bin目录
–with-release 指定按release版本的参数进行编译，如果不指定这个参数，则会按开发版本比较严格的参数编译，包含-Werror参数，所有的警告都会被当错误，在高版本gcc下会导致项目编译不过，很多开源用户反馈的编译问题都跟这个有关，因为gcc高版本对代码的检查越来越严格，淘宝内部使用的gcc版本是gcc-4.1.2。

四、配置文件：

hash_slot_ratio = 0.5

五、启动说胆：
1、运行TFS
启动nameserver
执行scripts目录下的tfs：

# ./tfs start_ns
 nameserver is up SUCCESSFULLY pid: 24744

2、启动DS
现有TFS可以在一台服务器上启动多个DataServer进程。一般每个DataServer进程负责一个磁盘。
将数据盘格式化成EXT4文件系统，并挂载到/data/tfs1至/data/tfs(i)，其中i为磁盘号。
启动步骤：
A、存储区预分配。执行scripts下的stfs format n (n为挂载点的序号，具体用法见stfs的Usage)。例如stfs format 2,4-6 则会对/data/tfs2,
/data/tfs4,/data/tfs5,/data/tfs6，进行预分配。运行完后会在生成/data/tfs2, /data/tfs4,/data/tfs5,/data/tfs6下预先创建主块，扩展块及相应的统计信息。

# ./stfs clear 1
 clear ds 1 SUCCESSFULLY 
 [2014-08-07 10:59:11] INFO  blockfile_manager.cpp:111 [140398366021408] clear block file system end. mount_point: /data/disk1, ret: 1

B、运行data server。有两种方法：
通过adminserver来启动dataserver（推荐）: 执行scripts下的./tfs admin_ds
直接启动dataserver，执行scripts下的./tfs start_ds 2,4-6，则会启动dataserver2，dataserver4，dataserver5，dataserver6

# ./tfs start_ds 1
 dataserver 1 is up SUCCESSFULLY pid: 2212
# ./tfs start_ds 2
 dataserver 2 is up SUCCESSFULLY pid: 28715 

# netstat -lantp | grep dataserver
tcp        0      0 0.0.0.0:8200                0.0.0.0:*                   LISTEN      2960/dataserver

# netstat -lantp | grep dataserver

程序基本上启动起来了
