　　1、基本配置
　　
# is this config file disabled
# false for enabled
# true for disabled
disabled=false# the name of the group this storage server belongs to
group_name=group1# bind an address of this host
# empty for bind all addresses of this host
bind_addr=10.16.125.32# if bind an address of this host when connect to other servers
# (this storage server as a client)
# true for binding the address configed by above parameter: "bind_addr"
# false for binding any address of this host
client_bind=true# the storage server port
port=21000# connect timeout in seconds
# default value is 30s
connect_timeout=30# network timeout in seconds
# default value is 30s
network_timeout=60# heart beat interval in seconds
heart_beat_interval=30# disk usage report interval in seconds
stat_report_interval=60# the base path to store data and log files
base_path=/home/openpf/app/fdfs407/base-g1# max concurrent connections the server supported
# default value is 256
# more max_connections means more memory will be used
max_connections=1024# the buff size to recv / send data
# this parameter must more than 8KB
# default value is 64KB
# since V2.00
buff_size = 256KB　　
　　
# accept thread count
# default value is 1
# since V4.07
accept_threads=1# work thread count, should <= max_connections
# work thread deal network io
# default value is 4
# since V2.00

# default value is 0 (short connection)
keep_alive=0# namespace for storing file indexes (key-value pairs)
# this item must be set when check_file_duplicate is true / on
key_namespace=FastDFS# if check file duplicate, when set to true, use FastDHT to store file indexes
# 1 or yes: need check
# 0 or no: do not check
# default value is 0
check_file_duplicate=0# the NIC alias prefix, such as eth in Linux, you can see it by ifconfig -a
# multi aliases split by comma. empty value means auto set by OS type
# default values is empty
if_alias_prefix=# the priority as a source server for uploading file.
# the lower this value, the higher its uploading priority.
# default value is 10

#standard log level as syslog, case insensitive, value list:
### emerg for emergency
### alert
### crit for critical
### error
### warn for warning
### notice
### info
### debug
log_level=info
# allow_hosts can ocur more than once, host can be hostname or ip address,
# &quot;*&quot; means match all ip addresses, can use range like this: 10.0.1.[1-15,20] or
# host[01-08,20-25].domain.com, for example:
# allow_hosts=10.0.1.[1-15,20]
# allow_hosts=host[01-08,20-25].domain.com

# store_path (disk), value can be 1 to 256, default value is 256

　　二、IO
　　
# if disk read / write separated
##  false for mixed read and write
##  true for separated read and write
# default value is true
# since V2.00
disk_rw_separated = true# disk reader thread count per store base path
# for mixed read / write, this parameter can be 0
# default value is 1
# since V2.00

# for mixed read / write, this parameter can be 0
# default value is 1
# since V2.00
disk_writer_threads = 1　　
　　3、同步

　　
# after sync a file, usleep milliseconds
# 0 for sync successively (never call usleep)
sync_interval=0# when no entry to sync, try read binlog again after X milliseconds
# must > 0, default value is 200ms
sync_wait_msec=50# storage sync start time of a day, time format: Hour:Minute
# Hour from 0 to 23, Minute from 0 to 59
sync_start_time=00:00# storage sync end time of a day, time format: Hour:Minute
# Hour from 0 to 23, Minute from 0 to 59
sync_end_time=23:59# write to the mark file after sync N files
# default value is 500
write_mark_file_freq=500# call fsync to disk when write big file
# 0: never call fsync
# other: call fsync when written bytes >= this bytes
# default value is 0 (never call fsync)
fsync_after_written_bytes=0# sync log buff to disk every interval seconds
# must > 0, default value is 10 seconds
sync_log_buff_interval=10# sync binlog buff / cache to disk every interval seconds
# default value is 60 seconds
sync_binlog_buff_interval=10# sync storage stat info to disk every interval seconds
# default value is 300 seconds
sync_stat_file_interval=3004、HTTP相关
　　
　　
# use the ip address of this storage server if domain_name is empty,
# else this domain name will ocur in the url redirected by the tracker server
http.domain_name=# the port of the web server on this storage server
