第一部分 FastDFS介?
1.FastDFS是什?
FastDFS是一款?Google FS的?源分布式文件系?,它用?C?言???,支持Linux、FreeBSD、AIX等UNIX系?。它只能通??S?PI?ξ募?M行存取???,不支持POSIX接口方式,不能mount使用。
准?地?,Google FS以及FastDFS、mogileFS、 HDFS、TFS等?Google FS都不是系??的分布式文件系?,而是??眉?的分布式文件存?Ψ?铡
FastDFS的作者是??c,?在淘???Java中?件?F??氖?ava基?平台研?工作。
以上文字引用自<<程序?T>> 文章 <<分布式文件系?FastDFS架??剖析>> http://www.programmer.com.cn/tag/fastdfs-架??/
2.FastDFS的?系???
3.FastDFS工作?程
1. Client???Tracker server上?鞯降?torage server;
2. Tracker server返回一台可用的Storage server,返回的?????Storage server的IP地址和端口;
3. Client直接和?Storage server建立?接,?行文件上?鳎?torage server返回新生成的文件ID,文件上?鹘Y束。
1. Client???Tracker server可以下?指定文件的Storage server,参?滴?募?D(包含?名和文件名);
2. Tracker server返回一台可用的Storage server;
3. Client直接和?Storage server建立?接,完成文件下?。
FastDFS??1.20?始,支持通?HTTP?f?下?文件。
1.用??g?器???Tracker server?戎玫?eb Server,URL中包含文件ID(包含?名和文件名);
2.Tracker server?⑦@??HTTP?求redirect到一台可用的Storage server的Web Server上(可以是apache或nginx);
3.用??g?器直接?Storage server的Web Serverr建立?接,完成文件下?。
第二部分 FastDFS+nginx_module配置手?
1.系??境
最小化安?的 CentOS 5.6 x86_64
tracker server: 192.168.3.220
storage server: 192.168.3.226
2.?境准??所有服?掌魃喜僮?
为了速度,配置使用sohu的源
cd /etc/yum.repo.d/
wget http://go.rritw.com/mirrors.sohu.com/help/CentOS-Base-sohu.repo
安?EPEL源
rpm -ihv http://go.rritw.com/download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
安???工具和??nginx所需的??包
yum groupinstall "Development Tools"
yum install libevent-devel.x86_64 pcre-devel.x86_64 zlib-devel.x86_64
3.在tracker上的操作[安?tracker server]
[root@tracker]# wget http://go.rritw.com/fastdfs.googlecode.com/files/FastDFS_v3.05.tar.gz
[root@tracker]# tar xvzf FastDFS_v3.05.tar.gz
[root@tracker]# cd FastDFS
[root@tracker]# vi make.sh
?⑷缦?尚星斑?的"#"?h除
WITH_HTTPD=1
WITH_LINUX_SERVICE=1
[root@tracker]# ./make.sh
[root@tracker]# ./make.sh install
[root@tracker]# vi /etc/fdfs/tracker.conf
修改/etc/fdfs/tracker.conf,主要修改以下?商?,如有其他?整,可参考文?n自行?整,默?的配置也可以工作。
# the base path to store data and log files
base_path=/home/tracker ====> 放置data和log的目?
##include http.conf ====> #include http.conf ??一定要注意!是 #include,不是include!!!
[root@tracker]# mkdir -p /home/tracker
启??racker服?
[root@tracker]# /etc/init.d/fdfs_trackerd start
??8080,22122端口已???
[root@tracker]# netstat -nl|grep -E '8080|22122'
tcp 0 0 0.0.0.0:22122 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN
4.在storage上的操作
[root@storage]# wget http://go.rritw.com/fastdfs.googlecode.com/files/FastDFS_v3.05.tar.gz
[root@storage]# wget http://go.rritw.com/fastdfs.googlecode.com/files/fastdfs-nginx-module_v1.10.tar.gz
[root@storage]# wget http://go.rritw.com/nginx.org/download/nginx-1.0.11.tar.gz
[root@storage]# tar xvzf FastDFS_v3.05.tar.gz
[root@storage]# cd FastDFS
[root@storage]# ./make.sh
[root@storage]# ./make.sh install
[root@storage]# tar xvzf nginx-1.0.11.tar.gz
[root@storage]# tar xvzf fastdfs-nginx-module_v1.10.tar.gz
[root@storage]# cd nginx-1.0.11
[root@storage]# ./configure --prefix=/usr/local/nginx --add-module=/root/fastdfs-nginx-module/src
[root@storage]# make
[root@storage]# make install
[root@storage]# vi /etc/fdfs/storage.conf
修改/etc/fdfs/storage.conf,主要修改以下?滋?,如有其他?整,可参考文?n自行?整,默?的配置也可以工作。
# the name of the group this storage server belongs to
group_name=group1 ====> 此台storage server所?俚姆?掌鹘M名
# the base path to store data and log files

# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
store_path0=/home/storage ====> 放置文件的目?
# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=192.168.3.220:22122 ====> tracker server的ip和端口,此?可以??多??tracker server,每行一??
#HTTP settings
http.disabled=true ====> ???戎玫?eb server
# the port of the web server on this storage server
http.server_port=80 ====> web server的端口改成80
[root@storage]# cp /root/fastdfs-nginx-module/mod_fastdfs.conf /etc/fdfs/
[root@storage]# vi /etc/fdfs/mod_fastdfs.conf
# the base path to store log files
base_path=/home/storage ====> 放置log的目?
# FastDFS tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=192.168.3.220:22122 ====> tracker server的ip和端口,此?可以??多??tracker server,每行一??
# the group name of storage server
group_name=group1 ====> 此台storage server所?俚姆?掌鹘M名
# if uri including group name
# default value is false

# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
store_path0=/home/storage ====> 放置文件的目?
[root@storage]# mkdir -p /home/storage
在nginx的server配置段中增加M00的location?明
[root@storage]# vi /usr/local/nginx/conf/nginx.conf
location /group1/M00 {
root /home/storage/data;
ngx_fastdfs_module;
}
??建M00目?的??接
[root@storage]# ln -s /home/storage/data /home/storage/data/M00
启??torage服?
[root@storage]# /etc/init.d/fdfs_storaged start
启??ginx
[root@tracker]# /usr/local/nginx/sbin/nginx
??8080,22122端口已???
[root@storage]# netstat -nl|grep -E '80|23000'
tcp 0 0 0.0.0.0:23000 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
5.在tracker上的操作[作为client?y?]
修改/etc/fdfs/client.conf文件,主要修改以下?滋?,如有其他?整,可参考文?n自行?整,默?的配置也可以工作。
# the base path to store log files
base_path=/tmp
# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=192.168.3.220:22122
??建一??用於?y?的文件demofile.txt
[root@tracker]# vi demofile.txt
?热菥鸵恍凶? dddddddddd
使用自?У?dfs_test上?魑募?y?。
[root@tracker]# /usr/local/bin/fdfs_test /etc/fdfs/client.conf upload demofile.txt

6.使用?g?器打?上?鞯奈募
我??在?g?器中?入http://go.rritw.com/192.168.3.220:8080/group1/M00/00/00/wKgD4k8ZC1SNK-NYAAAAC3lx3Rk484.txt
可以看到,???的地址已?被redirect到了storage server的IP(192.168.3.226)了。
