    FastDFS配置说明

    1)tracker.conf

    # is this config file disabled

    # false for enabled

    # true for disabled

    disabled=false

    #用于说明这个配置文件是否可用,false为可用。

     

    # bind an address of this host

    # empty for bind all addresses of this host

    bind_addr=

    #是否绑定ip

    #bind_addr=后面即为绑定的ip地址,常用于一台服务器有多个ip地址,希望其中的一个ip地址提供服务。不设置时,绑定所有的地址。一般情况下保持默认的不设置即可。

     

    # the tracker server port

    port=22122

    #tracker提供服务的端口号。

     

    # connect timeout in seconds

    # default value is 30s

    connect_timeout=30

    #网络连接超时时间,以秒为单位。针对socket套接字函数connect

     

    # network timeout in seconds

    # default value is 30s

    network_timeout=60

    #  tracker server的网络超时,单位为秒。发送或接收数据时,如果在超时时间后还不能发送或接收数据,则本次网络通信失败。

     

    # the base path to store data and log files

    base_path=/home/chenfeic/fdfs

     #存放数据和日志的根目录地址(这个目录必须存在,其下的子目录自动生成)

    此目录说明:

        {base_path}/data/storage_groups_new.dat:存储分组信息(data目录自动生成)

         {base_path}/data/storage_servers_new.dat:存储服务器(storage)列表

        {base_path}/logs/trackerd.log:tracker server日志文件

     

    # max concurrent connections this server supported

    max_connections=256

     #系统提供服务时的最大连接数

     

    # work thread count, should <= max_connections

    # default value is 4

    # since V2.00

    work_threads=4

    #工作线程数,通常设置为CPU数。此值不能超过max_connections,默认是4

     

    # the method of selecting group to upload files

    # 0: round robin

    # 1: specify group

    # 2: load balance, select the max free space group to upload file

    store_lookup=2

    #上传文件到组 的方式 0:轮询方式 1: 指定组 2: 平衡负载(选择最大剩余空间的组上传)。默认是选择最大剩余空间。

     

    # which group to upload file

    # when store_lookup set to 1, must set store_group to the group name

    store_group=group2

    #当上一个参数设定为1 时 (store_lookup=1,即指定组名时),必须设置本参数为系统中存在的一个组名。如果选择其他的上传方式,这个参数就没有效了。

     

    # which storage server to upload file

    # 0: round robin (default)

    # 1: the first server order by ip address

    # 2: the first server order by priority (the minimal)

    store_server=0

    #选择哪个storage server 进行上传操作(一个文件被上传后,这个storage server就相当于这个文件的storage server源,会对同组的storage server推送这个文件达到同步效果)

    # 0: 轮询方式 (默认方式)

    # 1: 根据ip 地址进行排序选择第一个服务器(IP地址最小者)

    # 2: 根据优先级进行排序(上传优先级由storage server来设置,参数名为upload_priority) 

     

    # which path(means disk or mount point) of the storage server to upload file

    # 0: round robin

    # 2: load balance, select the max free space path to upload file

    store_path=0

    选择storage server 中的哪个目录进行上传。storage server可以有多个存放文件的base path(可以理解为多个磁盘)。

    # 0: 轮流方式,多个目录依次存放文件

    # 2: 选择剩余空间最大的目录存放文件

     

    # which storage server to download file

    # 0: round robin (default)

    # 1: the source storage server which the current file uploaded to

    download_server=0

    # 选择哪个 storage server 作为下载服务器 

    # 0: 轮询方式,可以下载当前文件的任一storage server

    # 1: 哪个为源storage server 就用哪一个 (前面说过了这个storage server源 是怎样产生的) 就是之前上传到哪个storage server服务器就是哪个了

     

    # reserved storage space for system or other applications.

    # if the free(available) space of any stoarge server in

    # a group <= reserved_storage_space,

    # no file can be uploaded to this group.

    # bytes unit can be one of follows:

    ### G or g for gigabyte(GB)

    ### M or m for megabyte(MB)

    ### K or k for kilobyte(KB)

    ### no unit for byte(B)

    ### XX.XX% as ratio such as reserved_storage_space = 10%

    reserved_storage_space = 10%

    # storage server 上保留的空间,保证系统或其他应用需求空间。可以用绝对值或者百分比。只要同组内任一storage server剩余空间小于这个值,就不允许再上传文件。

    #(注意如果同组的服务器的硬盘大小一样,以最小的为准,也就是只要同组中有一台服务器达到这个标准了,这个标准就生效,原因就是因为他们进行备份)

    # 注意:tracker server 的日志不是时时写硬盘的,而是先写内存。

     

    # check storage server alive interval seconds

    check_active_interval = 120

    # 检测 storage server 存活的时间隔,以秒为单位。

    # storage server定期向tracker server 发心跳,如果tracker server在一个check_active_interval内还没有收到storage server的一次心跳,那边将认为该storage server已经下线。所以本参数值必须大于storage server配置的心跳时间间隔。通常配置为storage server心跳时间间隔的2倍或3倍。
