TFS（Taobao FileSystem）是一個高可擴充、高可用、高性能、面向網際網路服務的分布式檔案系統，其設計目标是支援海量的非結構化資料的存儲；TFS使用C++語言開發，需要運作在64bit Linux OS上，TFS為淘寶提供海量小檔案存儲，通常檔案大小不超過1M，滿足了淘寶對小檔案存儲的需求，被廣泛地應用 在淘寶各項應用中。它采用了HA架構和平滑擴容，保證了整個檔案系統的可用性和擴充性。同時扁平化的資料組織結構，可将檔案名映射到檔案的實體位址，簡化了檔案的通路流程，一定程度上為TFS提供了良好的讀寫性能。本文介紹如何在Linux環境編譯安裝TFS及相關使用說明：
一、安裝依賴的軟體包:
1、automake TFS基于automake工具建構:
| 1 | yum install automake . noarch |
2、libtool automake需要使用libtool:
| 1 | yum install libtool |
3、realine 用于指令行編輯的庫：
| 1 | yum install readline - devel |
4、libz-devel 用于資料壓縮/解壓縮：
| 1 | yum install zlib - devel |
5、uuid-devel 用于生成全局唯一ID：
| 1 2 | yum install e2fsprogs - devel yum install libuuid - devel |
6、tcmalloc google的記憶體管理庫(由玩googl被封，那就暫且跳過吧，可選)
二、安裝tb-common-utils
TFS使用tb-common-utils軟體包，tb-common-utils包含淘寶使用的基礎系統庫tbsys和網絡庫tbnet兩個元件；安裝tb-common-utils前需要設定環境變量TBLIB_ROOT，tbsys和tbnet将會被安裝TBLIB_ROOT對應的路徑（必須是絕對路徑）下，TFS會在這個路徑下查找tbsys、tbnet頭檔案和庫。
設定TBLIB_ROOT環境變量：
1、在~/.bash_profile檔案中加入，export TBLIB_ROOT=path_to_tbutil , 然後執行source：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | ~ / . 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、下載下傳源碼：
| 1 | # svn co -r 18 http://code.taobao.org/svn/tb-common-utils/trunk tb-common-utils |
注意： 這裡不要checkout最新版本，version18以後的修改導緻部分接口不能前向相容
| 1 2 3 4 5 6 7 8 9 | # 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 . |
這個錯誤是因為缺少gcc-c++：
| 1 | yum install gcc - c ++ |
如果一切順利，tb-common-utils已經安裝成功到$TBLIB_ROOT路徑下；
三、安裝TFS
TFS開源使用者大都隻使用TFS的基本功能，是以這個版本我們預設隻編譯TFS的nameserver，dataserver，client和tool，以去除對mysql的依賴，需要使用到rcserver（全局資源管理服務），metaserver(TFS自定義檔案名服務）的使用者請自行編譯安裝這兩個服務。
下載下傳源碼并安裝：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | # svn co http://code.taobao.org/svn/tfs/branches/dev_for_outer_users tfs # cd tfs/ # sh build.sh init + aclocal + libtoolize -- force -- copy libtoolize : putting auxiliary files in ` . '. libtoolize: copying file `./ltmain.sh' libtoolize : Consider adding ` AC_CONFIG_MACRO_DIR ( [ m4 ] ) ' to configure.ac and libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree. libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile . am . libtoolize : ` AC_PROG _RANLIB ' is rendered obsolete by `LT_INIT' + autoconf -- force + automake -- foreign -- copy -- add - missing configure . ac : 16 : installing ` . / config . guess ' configure.ac:16: installing `./config.sub' configure . ac : 8 : installing ` . / install - sh ' configure.ac:8: installing `./missing' src / adminserver / Makefile . am : installing ` . / depcomp ' # ./configure --prefix=/usr/local/taobaoFS --with-release checking for tc_cfree in -ltcmalloc... no configure: error: in `/usr/local/tfs/tfs' : configure : error : tcmalloc link failed ( -- without - tcmalloc to disable ) See ` config . log' for more details . |
注意，這裡報錯了，是因為之前我們沒有安裝tcmalloc，是以這裡要改一下編譯條件：
| 1 2 3 | # ./configure --prefix=/usr/local/taobaoFS --with-release --without-tcmalloc # make # make install |
–prefix 指定tfs安裝路徑，預設會被安裝到~/tfs_bin目錄
–with-release 指定按release版本的參數進行編譯，如果不指定這個參數，則會按開發版本比較嚴格的參數編譯，包含-Werror參數，所有的警告都會被當錯誤，在高版本gcc下會導緻項目編譯不過，很多開源使用者回報的編譯問題都跟這個有關，因為gcc高版本對代碼的檢查越來越嚴格，淘寶内部使用的gcc版本是gcc-4.1.2。
四、配置檔案：
ns.conf:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 | # cd /usr/local/taobaoFS/conf/ # cat ns.conf | grep -v ^# | grep -v ^$ [ public ] log_size = 1073741824 log_num = 8 log_level = info task_max_queue_size = 10240 port = 8108 work_dir = / usr / local / taobaoFS dev_name = eth0 thread_count = 32 ip_addr = 192.168.1.63 [ nameserver ] safe_mode_time = 360 ip_addr_list = 192.168.1.63 | 192.168.0.2 group_mask = 255.255.255.255 max_write_timeout = 3 cluster_id = 1 block_max_use_ratio = 98 block_max_size = 75497472 max_replication = 2 min_replication = 2 replicate_ratio = 50 max_write_filecount = 64 use_capacity_ratio = 96 heart_interval = 4 object_dead_max_time = 300 object_clear_max_time = 180 heart_thread_count = 4 heart_max_queue_size = 2048 report_block_thread_count = 6 report_block_max_queue_size = 32 report_block_hour_range = 2 ~ 4 report_block_time_interval = 1 repl_wait_time = 180 compact_delete_ratio = 10 compact_max_load = 200 compact_hour_range = 1 ~ 10 dump_stat_info_interval = 60000000 balance_percent = 0.05 add_primary_block_count = 3 task_percent_sec_size = 200 oplog_sync_max_slots_num = 1024 oplog_sync_thread_num = 1 group_count = 1 group_seq = 0 discard_newblk_safe_mode_time = 360 choose_target_server_random_max_num = 128 |
ds.conf:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | # cat ds.conf | grep -v ^# | grep -v ^$ [ public ] log_size = 1073741824 log_num = 8 log_level = info task_max_queue_size = 10240 port = 8200 work_dir = / usr / local / taobaoFS dev_name = eth0 thread_count = 32 ip_addr = 192.168.1.64 [ dataserver ] ip_addr = 192.168.1.63 ip_addr_list = 192.168.1.63 | 192.168.0.2 port = 8108 heart_interval = 2 check_interval = 2 replicate_threadcount = 2 block_max_size = 75497472 dump_visit_stat_interval = 60 backup_type = 1 mount_name = / data / disk mount_maxsize = 768959044 base_filesystem_type = 1 superblock_reserve = 0 avg_file_size = 15360 mainblock_size = 75497472 extblock_size = 4194304 block_ratio = 0.5 hash_slot_ratio = 0.5 |
第三台伺服器的ds配置如下：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | # cat ds.conf | grep -v ^# | grep -v ^$ [ public ] log_size = 1073741824 log_num = 8 log_level = info task_max_queue_size = 10240 port = 8200 work_dir = / usr / local / taobaoFS dev_name = eth0 thread_count = 32 ip_addr = 192.168.1.66 [ dataserver ] ip_addr = 192.168.1.63 ip_addr_list = 192.168.1.63 | 192.168.0.2 port = 8108 heart_interval = 2 check_interval = 2 replicate_threadcount = 2 block_max_size = 75497472 dump_visit_stat_interval = 60 backup_type = 1 mount_name = / data / disk mount_maxsize = 768959044 base_filesystem_type = 1 superblock_reserve = 0 avg_file_size = 15360 mainblock_size = 75497472 extblock_size = 4194304 block_ratio = 0.5 hash_slot_ratio = 0.5 |
五、啟動說膽：
1、運作TFS
啟動nameserver
執行scripts目錄下的tfs：
| 1 2 | # ./tfs start_ns nameserver is up SUCCESSFULLY pid : 24744 |
2、啟動DS
現有TFS可以在一台伺服器上啟動多個DataServer程序。一般每個DataServer程序負責一個磁盤。
将資料盤格式化成EXT4檔案系統，并挂載到/data/tfs1至/data/tfs(i)，其中i為磁盤号。
啟動步驟：
A、存儲區預配置設定。執行scripts下的stfs format n (n為挂載點的序号，具體用法見stfs的Usage)。例如stfs format 2,4-6 則會對/data/tfs2,
/data/tfs4,/data/tfs5,/data/tfs6，進行預配置設定。運作完後會在生成/data/tfs2, /data/tfs4,/data/tfs5,/data/tfs6下預先建立主塊，擴充塊及相應的統計資訊。

B、運作data server。有兩種方法：
通過adminserver來啟動dataserver（推薦）: 執行scripts下的./tfs admin_ds
直接啟動dataserver，執行scripts下的./tfs start_ds 2,4-6， 則會啟動dataserver2，dataserver4，dataserver5，dataserver6

程式基本上啟動起來了
