fastdfs操作順序

    fastdfs 安裝
    
    //查詢：
    docker search fastdfs
    
    //下載：
    docker pull season/fastdfs
    
   // 本機方式啟動註冊中心tracker：
   docker run -itd --name trakcer -v ~/tracker_data:/fastdfs/tracker/data --net=host season/fastdfs tracker
     預設啟動22122埠
     
   //  禁用防火牆：
    vi /
 
etc/sysconfig/selinux
    
   //重啟虛擬機器：
    reboot

防火牆禁用方法

啟動倉庫storage

   docker run -itd --name storage -v ~/storage_data:/fastdfs/storage/data -v ~/store_path:
   /fastdfs/store_path --net=host -e TRACKER_SERVER:192.168.1.2:22122 season/fastdfs storage

進入容器

	//進入容器:
	docker exec -it storage bash
	
	//檢視配置：
 

	more storage.conf
	
	//複製出來，修改配置再考回去
	docker cp storage.conf:/fdfs_conf ~/
	
	//考回去
	docker cp ./storage.conf  storage:/fdfs_conf/
	
	//因為docker是精簡版的系統,所以修改配置需要拷貝出來改好再複製回去
	

將ip修改為Linux系統Ip
重啟storage：docker stop storage → docker start storage
再次進入storage容器 docker exec -it storage bash

確認配置是否修改成功

下圖箭頭為組名，預設group1,依次往上加，有組號說明tracker已啟動

    fdfs_monitor fdfs_conf/storage.conf

》》測試檔案上傳
檢視/usr/bin下的所有fdfs工具

[root@bogon fdfs]# ls /usr/bin | grep fdfs

fdfs_trackerd
fdfs_upload_appender
fdfs_upload_file  //上傳檔案

啟動客戶端

//啟動容器
docker run -itd --name fdfs_sh --net=host season/fastdfs sh

//進入容器
docker exec -it sh bash

//建立檔案賦值
a.txt： echo  dajiahao>a.txt

//進入目錄
root@localhost:/#  cd fdfs_conf

//上傳檔案
root@localhost:/fdfs_conf#  fdfs_upload_file storage.conf /a.txt

//上傳成功 返回的地址

刪除檔案（fdfs_delete_file <config_file> <file_id>）

   [root@bogon 00]# fdfs_delete_file /etc/fdfs/client.conf group1/M00/00/00/wKiuglwGoJWARxYvAAAACZLaVGU072.txt
    #刪除了該檔案 還可以檢視到它的資訊
