一、Docker安装运行FastDFS
1.获取FastDFS镜像
# 从仓库拉取镜像
$ sudo docker image pull delron/fastdfs
# 解压⽂档中本地镜像
$ sudo docker load -i ⽂件路径/fastdfs_docker.tar
sudo docker load -i /home/sanha/fastdfs_docker.tar
创建挂载文件
# cd /var
# mkdir fdfs
# mkdir storage
# mkdir tracker
➜ ~ sudo su
[sudo] password for sanha:
root@sanha-virtual-machine:/home/sanha# cd /var/fdfs/
root@sanha-virtual-machine:/var/fdfs# ls
root@sanha-virtual-machine:/var/fdfs# mkdir storage
root@sanha-virtual-machine:/var/fdfs# mkdir tracker
root@sanha-virtual-machine:/var/fdfs# ls
storage tracker
root@sanha-virtual-machine:/var/fdfs#
2.开启tracker容器
我们将 tracker 运⾏⽬录映射到宿主机的 /var/fastdfs/tracker⽬录中。
sudo docker run -dit --name tracker --network=host -v /var/fdfs/tracker:/var/fdfs delron/fastdfs tracker
root@sanha-virtual-machine:/home/sanha# cd /var/fdfs/
root@sanha-virtual-machine:/var/fdfs# sudo docker run -dit --name tracker --network=host -v /var/fdfs/tracker:/var/fdfs delron/fastdfs tracker
26fef3c64e890d51d9e069de14defcd6ed3c3624d224e73194bf6ed67a416437
3.开启storage容器
TRACKER_SERVER=Tracker的ip地址:22122（Tracker的ip地址不要使⽤127.0.0.1）
我们将 storage 运⾏⽬录映射到宿主机的 /var/fdfs/storage⽬录中。
sudo docker run -dti --name storage --network=host -e TRACKER_SERVER=192.168.231.130:22122 -v /var/fdfs/storage:/var/fdfs delron/fastdfs storage
root@sanha-virtual-machine:/var/fdfs# sudo docker run -dti --name storage --network=host -e TRACKER_SERVER=192.168.231.130:22122 -v /var/fdfs/storage:/var/fdfs delron/fastdfs storage
324f0152a4a33315f024fd53d9fc0ac9f8d5836ee2eb568580fa12b2fc5bc6bf
4.启动容器
root@sanha-virtual-machine:/var/fdfs# sudo docker container start storage
storage
root@sanha-virtual-machine:/var/fdfs# sudo docker container start tracker
tracker
root@sanha-virtual-machine:/var/fdfs#
查看正在运行的容器
sudo docker container ls
5.查看宿主机映射路径
注意：如果⽆法重启storage容器，可以删除/var/fdfs/storage/data⽬录下fdfs_storaged.pid ⽂件，然后重新运⾏storage。
二、FastDFS客户端上传⽂件
Python版本的FastDFS客户端使⽤参考⽂档：https://github.com/JaceHo/fdfs_client-py
1.安装FastDFS客户端扩展
安装模块虚拟环境中
$ pip install py3Fdfs
$ pip install mutagen
$ pip install requests
(mg_env) ➜ apps git:(dev) ✗ pip install py3Fdfs
Collecting py3Fdfs

2.准备FastDFS客户端扩展的配置⽂件
mgproject.utils.fastdfs.client.conf
# connect timeout in seconds
# default value is 30s
connect_timeout=30
# network timeout in seconds
# default value is 30s
network_timeout=60
# the base path to store log files
base_path=/home/ynxiaolu/Desktop
# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=192.168.231.130:22122
3.FastDFS客户端实现⽂件存储
# 使⽤ shell 进⼊ Python交互环境
$ python manage.py shell
Python 3.8.10 (default, Nov 14 2022, 12:59:47)
[GCC 9.4.0] on linux
Django 2.2
# 1. 导⼊FastDFS客户端扩展
>>> from fdfs_client.client import Fdfs_client, get_tracker_conf
# 2. 创建FastDFS客户端实例
>>> tracker_path = get_tracker_conf('/home/sanha/Desktop/PythonProjects/mangguo/mgproject/mgproject/utils/fastdfs/client.conf')
>>> client = Fdfs_client(tracker_path)
# 3. 调⽤FastDFS客户端上传⽂件⽅法
>>> ret = client.upload_by_filename('/home/sanha/Desktop/sanha.jpg')
>>>
ret = {
'Group name': b'group1',
'Remote file_id':
b'group1/M00/00/00/wKjngmP8KOqAScumAAEYnyGQQes988.jpg',
'Status': 'Upload successed.',
'Local file name': '/home/sanha/Desktop/sanha.jpg',
'Uploaded size': '70.16KB',
'Storage IP': b'192.168.231.130'}
ret = {
'Group name': 'Storage组名',

'Status': '⽂件上传结果反馈',
'Local file name': '上传⽂件全路径',
'Uploaded size': '⽂件⼤⼩',
'Storage IP': 'Storage地址'
}

3. 浏览器下载并渲染图⽚
思考：如何才能找到在Storage中存储的图⽚？
协议：http
IP地址：192.168.231.130
Nginx服务器的IP地址。
因为 FastDFS 擅⻓存储静态⽂件，但是不擅⻓提供静态⽂件的下载服务，
所以我们⼀般会将 Nginx 服务器绑定到 Storage ，提升下载性能。
端⼝：8888
Nginx服务器的端⼝。
路径：group1/M00/00/00/wKjngmP8KOqAScumAAEYnyGQQes988.jpg
⽂件在Storage上的⽂件索引。
