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
  1. 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
  2. 安装Tracker Server -192.168.127.11

    • 引用上例中安装libevent 和 FastDFS步骤
    • 配置及启动Tracker Server,端口:22122

         #修改tracker.conf配置
   vim /etc/fdfs/tracker.conf
   # the tracker server port
   port=22122
   # the base path to store data and log files
   base_path=/home/yuqing/fastdfs -> base_path=/home/fastdfs/tracker #日志目录
   reserved_storage_space = 4GB -> reserved_storage_space = 1GB
   
         #启动Tracker Server
   /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
   
         #启动过程中出现的错误
   #./fdfs_trackerd: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory
   #解决办法
   ln -s /usr/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5
    • #检查tracker是否启动成功，可以查看如下文件

         vim /home/fastdfs/tracker/logs/trackerd.log
   #[2012-08-26 19:01:30] INFO - FastDFS v3.11, base_path=/home/fastdfs/tracker, run_by_group=, run_by_user=, connect_timeout=30s, network_timeout=60s, port=22122, bind_addr=, max_connections=256, work_threads=4, store_lookup=0, store_group=, store_server=0, store_path=0, reserved_storage_space=1024MB, download_server=0, allow_ip_count=-1, sync_log_buff_interval=10s, check_active_interval=120s, thread_stack_size=64 KB, storage_ip_changed_auto_adjust=1, storage_sync_file_max_delay=86400s, storage_sync_file_max_time=300s, use_trunk_file=0, slot_min_size=256, slot_max_size=16 MB, trunk_file_size=64 MB, trunk_create_file_advance=0, trunk_create_file_time_base=02:00, trunk_create_file_interval=86400, trunk_create_file_space_threshold=20 GB
   
         #启动成功，加入开机启动
   # vim /etc/rc.d/rc.local
   /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf

    安装Storage Server -192.168.127.12
    配置及启动存储服务(Storage Server)

    • 引用上例中安装libevent 和 FastDFS步骤 
    •    #修改storage.conf配置
   vim /etc/fdfs/storage.conf
   # the name of the group this storage server belongs to
   group_name=group1

   tracker_server=192.168.209.121:22122 -> tracker_server=192.168.127.11:22122

   #启动storage Server
   /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf

   #接下来会出现很多mkdir data path,这是系统在创建数据目录
   data path: /home/fastdfs/fdfs_storage/data, mkdir sub dir...
   mkdir data path: 00 ...
   mkdir data path: 01 ...
   mkdir data path: 02 ...

  3. 测试及使用FastDFS-192.168.127.11

    • FastDFS之配置client

        vim /etc/fdfs/client.conf
  base_path=/home/yuqing/fastdfs-> base_path=/home/fastdfs/tracker
  tracker_server=192.168.209.121:22122 -> tracker_server=192.168.127.11:22122
  
    •   cd /usr/local/bin
  vim aa.txt 增加内容:展示aa.txt文本数据   :wq
  ./fdfs_test /etc/fdfs/client.conf upload aa.txt

      执行成功后会出现如下提示：

        # ./fdfs_test /etc/fdfs/client.conf upload aa.txt
  [2012-08-25 02:08:26] INFO - base_path=/home/fastdfs/tracker, connect_timeout=30, network_timeout=60, tracker_server_count=1, anti_steal_token=0, anti_steal_secret_key length=0
  tracker_query_storage_store_list_without_group:
          server 1. group_name=group2, ip_addr=192.168.127.13, port=23000
  group_name=group2, ip_addr=192.168.127.6, port=23000
  storage_upload_by_filename
  group_name=group2, remote_filename=M00/00/00/wKh_BlA3wxql4hTXAAAAB8v-VvY710.txt
  source ip address: 192.168.127.13
  file timestamp=2012-08-25 02:08:26
  file size=7
  file crc32=3422443254
  file url:
  storage_upload_slave_by_filename
  group_name=group2, remote_filename=M00/00/00/wKh_BlA3wxql4hTXAAAAB8v-VvY710_big.txt
  source ip address: 192.168.127.6
  file timestamp=2012-08-25 02:08:26
  file size=7
  file crc32=3422443254
  file url:
  
        执行过程中可能出现防火墙封口：
  # ERROR - file: tracker_proto.c, line: 420, connect to 192.168.127.11:22122 fail, errno: 113, error info: No route to host
  解决：
  iptables -L;iptables -F;service iptables stop
    • 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
    • 常规命令范例:

        #启动tracker、storaged
  /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
  /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf

  #重启tracker、storaged
  /usr/local/bin/restart.sh  /usr/local/bin/fdfs_trackerd  /etc/fdfs/tracker.conf
  /usr/local/bin/restart.sh  /usr/local/bin/fdfs_storaged  /etc/fdfs/storage.conf

  #停止tracker、storaged
  /usr/local/bin/stop.sh  /usr/local/bin/fdfs_trackerd  /etc/fdfs/tracker.conf
  /usr/local/bin/stop.sh  /usr/local/bin/fdfs_storaged  /etc/fdfs/storage.conf

  #监控storage
  /usr/local/bin/fdfs_monitor /etc/fdfs/storage.conf
  #如果存在多个多个组，只需要监控其中一个组，就能调出所有组的状态

  #删除组内服务器storage和查看各个组内服务器状态
  /usr/local/bin/fdfs_monitor /etc/fdfs/client.conf delete group2 192.168.127.13
  /usr/local/bin/fdfs_monitor /etc/fdfs/client.conf
  storage server有7个状态，如下(数值从1~7)：
  # FDFS_STORAGE_STATUS：INIT      :初始化，尚未得到同步已有数据的源服务器
  # FDFS_STORAGE_STATUS：WAIT_SYNC :等待同步，已得到同步已有数据的源服务器
  # FDFS_STORAGE_STATUS：SYNCING   :同步中
  # FDFS_STORAGE_STATUS：DELETED   :已删除，该服务器从本组中摘除
  # FDFS_STORAGE_STATUS：OFFLINE   :离线
  # FDFS_STORAGE_STATUS：ONLINE    :在线，尚不能提供服务
  # FDFS_STORAGE_STATUS：ACTIVE    :在线，可以提供服务
