python-django框架中使用FastDFS分布式文件系统

一、安装FastDFS

1-1：执行docker命令安装

# 安装tracker
docker run -dti --network=host --name tracker -v /var/fdfs/tracker:/var/fdfs youkou1/fastdfs tracker

# 安装storage
docker run -dti --network=host --name storage -e TRACKER_SERVER=IP地址:22122 -v /var/fdfs/storage:/var/fdfs youkou1/fastdfs storage

1-2 测试是否安装成功：执行命令 docker ps -a

TRACKER_SERVER：IP地址说明不要使用lo 和docker下的IP地址因为在安装镜像中配的是enp3s0下面的IP地址。

1-3、在项目中创建客户端配置文件 fastdfs/client.conf

client.conf配置文件内容：注意tracker_serverIP地址。

# 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=utils/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=192.168.31.170:22122

#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
use_connection_pool = false

# connections whose the idle time exceeds this time will be closed
# unit: second
# default value is 3600
connection_pool_max_idle_time = 3600

# if load FastDFS parameters from tracker server
# 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
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
storage_ids_filename = storage_ids.conf


#HTTP settings
http.tracker_server_port=80

1-4：在xhell中进入项目的虚拟环境安装python相关包（在虚拟环境中）

# 安装相关包 
pip install fdfs_client.zip
pip install mutagen
pip install requests

1-5：如果pip install fdfs_client.zip 安装报错

请执行如下命令

sudo apt-get install python3 python-dev python3-dev build-essential libssl-dev libffi-dev libxml2-dev libxslt1-dev zlib1g-dev python-pip

然后在执行安装命令：

查看所安装的包：

分析上传步骤：
　　1）指定图片绝对地址
　　2）指定图片服务器地址；使用 Client.conf 配置文件
　　3）加载图片服务器，连接图片服务器
　　4）创建图片服务器 tracker 客户端
　　5）从客户端获取 tracker 连接

　　6）创建 storage 客户端，存储图片

测试代码：

from fdfs_client.client import Fdfs_client
FDFS_Client = Fdfs_client('/common/fastdfs/client.conf')
ret = FDFS_Client.upload_by_filename('/media/2018.png')
print(ret)

　　如果执行不报错，返回结果如下说明就成功了：
