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)
#standard log level as syslog, case insensitive, value list:
### emerg for emergency
### alert
### crit for critical
### error
### warn for warning
### notice
### info
### debug

# allow_hosts can ocur more than once, host can be hostname or ip address,
# "*" means match all ip addresses, can use range like this: 10.0.1.[1-15,20] or

# 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。
