什么是 InvenTree ？
InvenTree是一个开源的库存管理系统，提供强大的低级别库存控制和零件跟踪。InvenTree系统的核心是Python/Django数据库后端，它提供了一个管理界面（基于web）和一个REST API，用于与外部接口和应用程序交互。强大的插件系统为自定义应用程序和扩展提供支持。
前期准备
在群晖上以 Docker 方式安装。因为涉及到多个容器，所以采用了 docker-compose 安装
老苏是按生产环境搭建，因为开发模式只能用 localhost 访问，所需的文件都来自于官方的 production 目录：https://github.com/inventree/InvenTree/tree/master/docker/production
版本选择的是
InvenTree的最新稳定版本stable，对应的版本为0.12.8
docker-compose.yml
将下面的内容保存为 docker-compose.yml 文件
version: "3.8"# Docker compose recipe for a production-ready InvenTree setup, with the following containers:
# - PostgreSQL as the database backend
# - gunicorn as the InvenTree web server
# - django-q as the InvenTree background worker process
# - nginx as a reverse proxy
# - redis as the cache manager (optional, disabled by default)# ---------------------
# READ BEFORE STARTING!
# ---------------------# -----------------------------
# Setting environment variables
# -----------------------------
# Shared environment variables should be stored in the env.txt file
# Changes made to this file are reflected across all containers!
#
# IMPORTANT NOTE:
# You should not have to change *anything* within this docker-compose.yml file!
# Instead, make any changes in the env.txt file!# ------------------------
# InvenTree Image Versions
# ------------------------
# By default, this docker-compose script targets the STABLE version of InvenTree,
# image: inventree/inventree:stable
#
# To run the LATEST (development) version of InvenTree,
# change the INVENTREE_TAG variable (in the env.txt file) to "latest"
#
# Alternatively, you could target a specific tagged release version with (for example):
# INVENTREE_TAG=0.7.5

相比官方的 docker-compose.yml，老苏做了 2 处修改，但都不是必须的，你可以直接用官方原版的
nginx的版本，官方用的是nginx:stable，老苏为了少下载一个镜像，改为了nginx，也就是nginx:latest，因为机器上已经有了，这个不是必须要改的；- 给每个容器增加了
container_name，只是为了看着舒服，同样也不是必须的；
nginx.prod.conf
将下面的内容保存为 r-compose.yml 文件，不需要做任何改动
server {# Listen for connection on (internal) port 80# If you are exposing this server to the internet, you should use HTTPS!# In which case, you should also set up a redirect from HTTP to HTTPS, and listen on port 443# See the Nginx documentation for more detailslisten 80;real_ip_header proxy_protocol;location / {proxy_set_header Host $http_host;proxy_set_header X-Forwarded-By $server_addr:$server_port;proxy_set_header X-Forwarded-For $remote_addr;proxy_set_header X-Forwarded-Proto $scheme;proxy_set_header X-Real-IP $remote_addr;proxy_set_header CLIENT_IP $remote_addr;proxy_pass_request_headers on;proxy_redirect off;client_max_body_size 100M;proxy_buffering off;proxy_request_buffering off;# Do not touch this unless you have a specific reason - this and the docker-compose need to matchproxy_pass http://inventree-server:8000;}# Redirect any requests for static fileslocation /static/ {alias /var/www/static/;autoindex on;# Caching settingsexpires 30d;add_header Pragma public;add_header Cache-Control "public";}# Redirect any requests for media fileslocation /media/ {alias /var/www/media/;# Media files require user authenticationauth_request /auth;# Content header to force downloadadd_header Content-disposition "attachment";}# Use the 'user' API endpoint for authlocation /auth {internal;proxy_pass http://inventree-server:8000/auth/;proxy_pass_request_body off;proxy_set_header Content-Length "";proxy_set_header X-Original-URI $request_uri;}}
.env
将下面的内容保存为 .env 文件
# InvenTree environment variables for a postgresql production setup# Location of persistent database data (stored external to the docker containers)
# Note: You *must* un-comment this line, and point it to a path on your local machine# e.g. Linux

参数说明：
- 基本设置
INVENTREE_EXT_VOLUME：映射为卷的本地目录，需要根据自己的目录进行修改；INVENTREE_WEB_PORT：访问时的Web端口，本地不冲突就可以；INVENTREE_DEBUG：调试模式，默认False为关闭；INVENTREE_LOG_LEVEL：日志级别；
【建议】：前两项需要根据自己的情况就行修改；
- 管理员设置
INVENTREE_ADMIN_USER：管理员账号；INVENTREE_ADMIN_PASSWORD：管理员密码；INVENTREE_ADMIN_EMAIL：管理员邮件地址；
【建议】：三项都需要根据自己的情况进行修改；这里如果不设置，就需要用命令行去单独创建管理员；
- 数据库设置
INVENTREE_DB_ENGINE：数据库类型，除了postgresql外，还支持mysqlINVENTREE_DB_NAME：数据库库名；INVENTREE_DB_HOST：数据库主机；INVENTREE_DB_PORT：数据库端口；INVENTREE_DB_USER：数据库用户；INVENTREE_DB_PASSWORD：数据库密码；
【建议】：只要修改密码就可以的，其他的不建议修改；
Redis设置INVENTREE_CACHE_HOST：Redis主机，默认本行被注释，在数据库初始化之前，一定不要取消注释；INVENTREE_CACHE_PORT：Redis端口，默认本行被注释，在数据库初始化之前，一定不要取消注释；
【强烈建议】：不管你后续是否要使用
Redis，在数据库初始化之前，一定不要取消注释，否则会报错的，切记！切记！
- 其他
INVENTREE_GUNICORN_TIMEOUT：服务器超时设置；INVENTREE_PLUGINS_ENABLED：是否启用自定义插件；INVENTREE_TAG：镜像的tag的版本，不建议修改；COMPOSE_PROJECT_NAME：默认就可以；
【建议】：保持默认就可以了；
更多的参数说明，请看官方文档：https://docs.inventree.org/en/stable/start/config/
以上建议是给和老苏一样的小白用户的，高手请忽略
命令行安装
上传文件
文件准备好之后，依次执行下面的命令
# 新建文件夹 inventree 和 子目录
mkdir -p /volume1/docker/inventree/data# 进入 inventree 目录
cd /volume1/docker/inventree# 将 docker-compose.yml 、.env 、 nginx.prod.conf 放入当前目录
现在的目录
初始化
# 初始化数据库
docker-compose run inventree-server invoke update
这行初始化命令执行了以下步骤：
- 确保安装了所需的
python包 - 创建一个新的（空）数据库
- 执行所需的架构更新以创建所需的数据库表
- 更新翻译文件
- 将所有必需的静态文件收集到可由
nginx提供服务的目录中
一定不要先注释 .env 中的 redis 设置，否则最后 Running InvenTree database migrations... 时会有错误
redis.exceptions.ConnectionError: Error -2 connecting to inventree-cache:6379. Name or service not known.
正常应该是下面这样的
创建管理员
- 已在
.env中指定管理员帐户详细信息，可以跳过这一步； - 为了安全起见，请确保在首次运行后从
.env文件中删除管理员帐户凭据；
# 创建管理员账号
docker-compose run inventree-server invoke superuser
启动 Docker 容器
现在可以开始启动了
# 一键启动（不带 redis）
docker-compose up -d
如果需要 Redis 服务 ，首先修改 .env 中的 redis 设置，取消 INVENTREE_CACHE_HOST 和 INVENTREE_CACHE_PORT 前面的注释
如果你取消了
redis注释，但是执行的又是不带redis的一键启动，也是会存在错误的，或导致容器不断重启；
然后再执行下面的启动命令
# 一键启动（带 redis）
docker-compose --profile redis up -d
不出意外的话，我们在 Docker 管理器中应该看到下面这样
inventree-production_inventree-server_run_2a703d49eef5是初始化数据库的时候生成的，看着不爽的话，可以删掉
运行
在浏览器中输入 http://群晖IP:1337 就能看到登录界面
用我们前面设置的管理员账号、密码登录
主界面默认有部分中文显示，显然翻译程度还不高
不知道初始化时最一行显示的
InvenTree translation coverage: 27%是不是指的中文翻译；
如果看到下面的提示，只要重启 inventree-server 容器即可
Server Restart Required
A configuration option has been changed which requires a server restart. Contact your system administrator for further information
其他
一些其他可能会用到的命令
# 一键删除
docker-compose down# 将数据库导出为 JSON
docker-compose run inventree-server invoke export-records -f /volume1/docker/inventree/data/data.json# 删除卷
docker volume rm -f inventree_data
