fastdfs

总结：通过nginx的代理拦截，不同路径请求到不同的预设路径下

fastdfs结合nginx使用实现访问

环境介绍:

1: 公司目前有5个项目 A B C D E 日后可能会有所增加.

2: 使用fastdfs存储这5各项目的文件,要求各各项目的文件分开存储,也就是每个项目的文件存储到一个固定的位置.

3: 三台机器ip地址分配如下

tracker角色 IP:192.168.1.219

storageA角色 IP: 192.168.1.215

storageB角色 IP:192.168.1.216

4: 这里主要记录下实现思路,具体的配置方法都很简单.

---------tracker这台机器主要有两个服务 fdfs_tracker 和 nginx---------------

tracker.conf的配置文件很简单这里不贴出来了

nginx的配置文件如下: nginx负责把访问请求转发给后台的两台storage.

[root@trackerB ~]# cat /usr/local/nginx/conf/nginx.conf | grep -v "#" | grep -v "^$"

}

}

---------------storage角色的两台机器-------------------

这两天机器的配置完全一样. 都运行了fdfs_storage 和 nginx , 其中nginx添加了fastdfs模块

fdfs_storage的配置文件storage.conf内容如下:

[root@localhost ~]# cat /etc/fdfs/storage.conf | grep -v "^#" | grep -v "^$"

nginx配置文件如下

[root@localhost ~]# cat /usr/local/nginx/conf/nginx.conf | grep -v "^#" | grep -v "^$"

worker_processes 1;

events {

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for"';

access_log logs/access.log main;

sendfile on;

keepalive_timeout 65;

client_max_body_size 2m;

server {

listen 80;

server_name localhost;

#charset koi8-r;

access_log logs/host.access.log main;

location /group1/M00 { #根据请求路径配置对应的存储路径.

root /data/data1;

ngx_fastdfs_module; #使用nginxmodule处理请求

}

location /group1/M01 {

root /data/data2;

ngx_fastdfs_module;

}

location /group1/M02 {

root /data/data3;

ngx_fastdfs_module;

}

location /group1/M03 {

root /data/data4;

ngx_fastdfs_module;

}

location /group1/M04 {

root /data/data5;

ngx_fastdfs_module;

}

location /group1/M05 {

ngx_fastdfs_module;

}

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root html;

}

include /usr/local/nginx/conf/vhosts/*.conf;

}

nginx的fastdfs模块的配置文件如下:

[root@localhost ~]# cat /etc/fdfs/mod_fastdfs.conf | grep -v "^#" | grep -v "^$"

connect_timeout=2

network_timeout=30

base_path=/tmp

load_fdfs_parameters_from_tracker=true

storage_sync_file_max_delay = 86400

use_storage_id = false

storage_ids_filename = storage_ids.conf

tracker_server=192.168.1.219:22122

storage_server_port=23000

group_name=group1

url_have_group_name = true

store_path_count=6

store_path0=/data/data1

store_path1=/data/data2

store_path2=/data/data3

store_path3=/data/data4

store_path4=/data/data5

store_path5=/data/data6

log_filename=/var/log/mod_fastdfs.log

response_mode=proxy

if_alias_prefix=

flv_support = true

flv_extension = flv

group_count = 0

-----------------以上就是用到的所有配置文件----------------------------

想实现按照不通的项目存储到不同的路径,主要通过代码来实现以java为例

首先: 我们可以通过tracker获取一个可以使用的storage的ip, -------java代码如下---------

/**
* 获得可用的storage IP
*
* @param trackerClient
* @param trackerServer
* @return 返回storage IP
*/
private static String getStorageServerIp(TrackerClient trackerClient, TrackerServer trackerServer) {
String storageIp = null;
if (trackerClient != null && trackerServer != null) {
try {
StorageServer storageServer = trackerClient.getStoreStorage(trackerServer, STORAGE_SERVER_GROUP);
storageIp = storageServer.getSocket().getInetAddress().getHostAddress();
} catch (IOException e) {
e.printStackTrace();
}
}
log.info("——获取组中可用的storage IP——" + storageIp);
return storageIp;
}

其次:可以根据获取的ip把需要上传的文件指定到要上传到的路径里面

/**
* 得到Storage服务
*
* @param storageIp
* @return 返回Storage服务
*/
private static StorageServer getStorageServer(String storageIp) {
StorageServer storageServer = null;
if (storageIp != null && !("").equals(storageIp)) {
try {
storageServer = new StorageServer(storageIp, Integer.parseInt(STORAGE_SERVER_PORT), Integer.parseInt(STORAGE_SERVER_M00));
} catch (IOException e) {
e.printStackTrace();
}
}
log.info("——storage server生成");
return storageServer;
}
