fastdfs的安装配置比较复杂，不过网上有人做的docker可以直接拿来用，记录下过程。
一、Centos7安装docker安装步骤参照清华源说明：https://mirrors.tuna.tsinghua.edu.cn/help/docker-ce/
（一）如果之前安装过 docker，请先删掉
sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine
（二）安装一些依赖
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
（三）下载docker-ce.repo
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
（四）把软件仓库地址替换为 TUNA:
sudo sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo
（五）最后安装
sudo yum makecache fast sudo yum install docker-ce
（六）安装后启动docker
systemctl start docker
查看状态
systemctl status docker二、获取并运行fastdfs的docker镜像
docker的常用命令不赘述，网上资料很多
（一）获取fastdfs的docker镜像docker image pull delron/fastdfs
如果已经下载好的该镜像可以用load命令加载镜像：
docker load -i 文件路径/fastdfs_docker.tar（二）在运行fastdfs镜像时需要将容器中的运行目录映射到宿主机的目录，这里在Centos中先创建好
mkdir -p /var/fdfs/tracker mkdir -p /var/fdfs/storage（三）运行fastdfs镜像
fastdfs镜像要运行2次，先运行tracker server，再运行storage server，顺序不能互换
1、运行tracker serverdocker run -dit --name tracker --network=host -v /var/fdfs/tracker:/var/fdfs delron/fastdfs tracker
-d是以守护进程的方式运行该tracker容器，–network为将容器的网络映射到主机，-v为映射目录，即宿主机目录:容器中目录
最后一个tracker为让tracker server运行
docker run -dti --name storage --network=host -e TRACKER_SERVER=192.168.5.192:22122 -v /var/fdfs/storage:/var/fdfs delron/fastdfs storage
各选项的含义与上面类似，其中TRACKER_SERVER=192.168.5.192:22122中的IP地址注意修改为自己宿主机的IP。
（四）检查容器的运行状态docker container list -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3ca387cac802 delron/fastdfs "/usr/bin/start1.sh …" 11 hours ago Up 10 hours storage 14b5a18cc965 delron/fastdfs "/usr/bin/start1.sh …" 11 hours ago Up 11 hours tracker三、windows 10安装fdfs_client-py-master.zip
开发端用的windows 10的python环境，安装fdfs_client-py-master.zip的时候有报错
（一）安装py3Fdfspip install py3Fdfs（二）修改fdfs_client-py-master.zip
需要修改2个地方，解压fdfs_client-py-master.zip
1、修改fdfs_clientstorage_client.py
注释第12行
#from fdfs_client.sendfile import *
2、修改setup.py
注释第33、34行
# 'ext_modules': [Extension('fdfs_client.sendfile',
# sources=['fdfs_client/sendfilemodule.c'])],
3、重新压缩为fdfs_client-py-master.zip
pip install fdfs_client-py-master.zip（三）安装mutagen
注意版本选择1.40，好像新的版本会报错
pip install mutagen==1.40（四）安装requests
pip install requests（五）windows10中的fastdfs的client.conf，自己根据自己的配置进行修改，特别是IP
# connect timeout in seconds # default value is 30s connect_timeout=30 # network timeout in seconds # default value is 30s network_timeout=120 # the base path to store log files base_path=../../logs/fastdfs-logs/ # tracker_server can ocur more than once, and tracker_server format is # "host:port", host can be hostname or ip address tracker_server=192.168.5.192:22122 #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 # 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 storage_ids_filename = storage_ids.conf #HTTP settings http.tracker_server_port=80 #use "#include" directive to include HTTP other settiongs ##include http.conf（六）使用python上传图片验证
进入python的命令行终端
>>> from fdfs_client.client import Fdfs_client
>>> client = Fdfs_client('utils/fastdfs/client.conf') # 配置文件目录
>>> client.upload_by_filename('E:/11-life/02-picture/tmp/1.JPG') # 要上传的图片路径
上传成功的话会有下面的提示
{'Group name': 'group1', 'Remote file_id': 'group1\M00/00/00/wKgFwGJ2ZEyAOBG2AABo9FzmFBU118.JPG', 'Status': 'Upl
oad successed.', 'Local file name': 'E:/11-life/02-picture/tmp/1.JPG', 'Uploaded size': '26.00KB', 'Storage IP':
'192.168.5.192'}
验证方法：http://192.168.5.192:8888/group1\M00/00/00/wKgFwGJ2ZEyAOBG2AABo9FzmFBU118.JPG
这个地方端口号好像必须是8888，不能改。
如果上传失败，可能是网络或防火墙的问题。
firewall-cmd --zone=public --add-port=23000/tcp --permanent firewall-cmd --zone=public --add-port=22122/tcp --permanent firewall-cmd --zone=public --add-port=8888/tcp --permanent systemctl restart firewalld
或者直接关闭防火墙
systemctl stop firewalld
