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

# 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

# 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
