FastDFS文件分布系统

原理图：介绍地址：http://www.oschina.net/p/fastdfs

　　　　　　　老大：跟踪器（tracker）：负责专门存储图片的所在地址
　　　　　　　小弟：存储节点（storage）：负责具体存储图片

 

FastDFS最低配置为6台：两台老大机(Tracker),两台小弟机为一组(storage),两台小弟机为一组(storage),

 

 

fdfs_client.conf 核心配置文件:

# connect timeout in seconds
# default value is 30s
connect_timeout=30

# network timeout in seconds
# default value is 30s
network_timeout=60

# the base path to store log files
base_path=/home/fastdfs

# tracker_server can ocur more than once, and tracker_server format is
#  "host:port", host can be hostname or ip address

#tracker_server=192.168.101.4:22122

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

# if use connection pool
# default value is false
# since V4.05
use_connection_pool = false

# connections whose the idle time exceeds this time will be closed
# unit: second
# default value is 3600
# since V4.05
connection_pool_max_idle_time = 3600

# if load FastDFS parameters from tracker server
# since V4.05
# default value is false
load_fdfs_parameters_from_tracker=false

# if use storage ID instead of IP address
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# default value is false
# since V4.05
use_storage_id = false

# specify storage ids filename, can use relative or absolute path
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# since V4.05

#HTTP settings
