一,fastdfs是什么

FastDFS是一个开源的分布式文件系统,她对文件进行管理,功能包括:文件存储、文件同步、文件访问(文件上传、文件下载)等,解决了大容量存储和负载均衡的问题。特别适合以文件为载体的在线服务,如相册网站、视频网站等等。

二,安装

wget http://fastdfs.googlecode.com/files/FastDFS_v1.22.tar.gz
tar zxf FastDFS_v1.22.tar.gz
cd FastDFS
./make.sh
mkdir /usr/local/include             #一般情况下,local下面会有一个include文件夹的,如果没有在建个目录
./make.sh install

三,fastdfs的配置

1),tracker server的配置

disabled=false
bind_addr=
port=22122
network_timeout=60
base_path=/home/zhangy/FastDFS
max_connections=32

# 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

# which group to upload file
# when store_lookup set to 1, must set store_group to the group name
store_group=group1

# which storage server to upload file
# 0: round robin (default)
# 1: the first server order by ip address
store_server=0

# 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

# which storage server to download file
# 0: round robin (default)
# 1: the source storage server which the current file uploaded to
download_server=0

# 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)
reserved_storage_space = 1GB

#standard log level as syslog, case insensitive, value list:

### alert
### crit for critical

# 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
# 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
allow_hosts=*

# sync log buff to disk every interval seconds
# default value is 10 seconds
sync_log_buff_interval = 10

# check storage server alive interval
check_active_interval = 120

# thread stack size, should > 512KB
# default value is 1MB
thread_stack_size=1MB

#HTTP settings
http.disabled=false
http.server_port=8080

#use "#include" directive to include http other settiongs
##include http.conf

2)storager server的配置

disabled=false
group_name=group1
bind_addr=

network_timeout=60
heart_beat_interval=30
stat_report_interval=60
base_path=/home/zhangy/FastDFS
#store_path0=/home/zhangy/FastDFS

max_connections=32

# when no entry to sync, try read binlog again after X milliseconds
# 0 for try again immediately (not need to wait)
sync_wait_msec=200

# after sync a file, usleep milliseconds
# 0 for sync successively (never call usleep)
sync_interval=0

# 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

# 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

# path(disk or mount point) count, default value is 1
store_path_count=1

# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
store_path0=/mnt/song/fastfds2
#store_path1=/home/zhangy/fastdfs2

# subdir_count  * subdir_count directories will be auto created under each
# store_path (disk), value can be 1 to 256, default value is 256
subdir_count_per_path=256

# tracker_server can ocur more than once, and tracker_server format is
#  "host:port", host can be hostname or ip address
tracker_server=192.168.1.71:22122

#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

#unix group name to run this program,
#not set (empty) means run by the group of current user

# allow_hosts=10.0.1.[1-15,20]
# allow_hosts=host[01-08,20-25].domain.com
allow_hosts=*

# the mode of the files distributed to the data path
# 0: round robin(default)
# 1: random, distributted by hash code
file_distribute_path_mode=0

# valid when file_distribute_to_path is set to 0 (round robin),
# when the written file count reaches this number, then rotate to next path
# default value is 100
file_distribute_rotate_count=100

# 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
# default value is 10 seconds
sync_log_buff_interval=10

# sync binlog buff / cache to disk every interval seconds
# this parameter is valid when write_to_binlog set to 1
# default value is 60 seconds
sync_binlog_buff_interval=60

# thread stack size, should > 512KB
# default value is 1MB
thread_stack_size=1MB

# 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

# namespace for storing file indexes (key-value pairs)
# this item must be set when check_file_duplicate is true / on
key_namespace=FastDFS

# set keep_alive to 1 to enable persistent connection with FastDHT servers
# default value is 0 (short connection)
keep_alive=0

# you can use "#include filename" (not include double quotes) directive to
# load FastDHT server list, when the filename is a relative path such as
# pure filename, the base path is the base path of current/this config file.
# must set FastDHT server list when check_file_duplicate is true / on
# please see INSTALL of FastDHT for detail
##include /home/yuqing/fastdht/conf/fdht_servers.conf

#HTTP settings
http.disabled=false
http.server_port=8888
http.trunk_size=256KB

#use "#include" directive to include HTTP other settiongs
##include http.conf

四,启动fastdfs
/usr/local/bin/fdfs_trackerd /etc/conf.d/tracker.conf       #启动tracker服务
/usr/local/bin/fdfs_storaged /etc/conf.d/storage.conf    #启动storager服务

[root@BlackGhost include]#  ps -e|grep fdfs
22790 ?        00:00:00 fdfs_trackerd
22845 ?        00:00:00 fdfs_storaged

说明已经启动了。

五,测试结果
在一台Storage Server上运行
#/usr/local/bin/fdfs_test /etc/conf.d/storage.conf upload needed_upload_filename

/usr/local/bin/fdfs_monitor /etc/conf.d/storage.conf      #查看一下,刚才上传的文件是不是传上去了。
