Casdoor 是一个基于 OAuth 2.0 / OIDC 的中心化的单点登录（SSO）身份验证平台，简单来说，就是 Casdoor 可以帮你解决用户管理的难题，你无需开发用户登录、注册等与用户鉴权相关的一系列功能，只需几个步骤进行简单配置，与你的主应用配合，便可完全托管你的用户模块，简单省心，功能强大。
官网有 demo 体验，及文档。本文是依照文档「服务器安装」「使用 Docker 运行」于 Ubuntu 22 上的实践记录。
安装环境
安装 Go
# 下载，依据系统选择 Linux x86-64 的发布包
curl -O -L https://go.dev/dl/go1.20.4.linux-amd64.tar.gz
# 解压
tar -xzvf go1.20.4.linux-amd64.tar.gz
# 重命名，带上版本号
mv go go1.20.4.linux-amd64
# 软链，便于配置或切版本
sudo ln -sfT `pwd`/go1.20.4.linux-amd64 /usr/local/go
# 配置，GOPATH 用自己的工作目录
cat <<-EOF >> ~/.bashrc
# go
export GOROOT=/usr/local/go
export GOPATH=\$HOME/Codes/Go
export PATH=\$GOROOT/bin:\$GOPATH/bin:\$PATH
EOF
# 检查
go version
go env
安装 Node.js
# 下载，选了当前最新的 LTS 版本，可用
curl -O -L https://nodejs.org/dist/v18.16.0/node-v18.16.0-linux-x64.tar.xz
# 解压
tar -xvf node-v18.16.0-linux-x64.tar.xz
# 软链，便于配置或切版本
sudo ln -sfT `pwd`/node-v18.16.0-linux-x64 /usr/local/node
# 配置，GOPATH 用自己的工作目录
cat <<-EOF >> ~/.bashrc
# node
export NODE_HOME=/usr/local/node
export PATH=\$NODE_HOME/bin:\$PATH
EOF
# 检查
node -v
npm -v
安装 Yarn
npm install yarn -g
# 检查
yarn -v
安装 MySQL
sudo apt update -y
# 安装
sudo apt install mysql-server -y
# 检查
systemctl status mysql.service
# 或启动
systemctl start mysql.service
配置 MySQL：
1 修改 root 用户的密码，
sudo mysql
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'YourPassword';
exit
不然，执行 mysql_secure_installation 会遇到如下错误：
... Failed! Error: SET PASSWORD has no significance for user 'root'@'localhost' as the authentication method used doesn't store authentication data in the MySQL server. Please consider using ALTER USER instead if you want to change authentication parameters.
2 执行配置脚本 mysql_secure_installation 把不安全的功能都给关了，
$ sudo mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root:
The 'validate_password' component is installed on the server.
The subsequent steps will run with the existing configuration
of the component.
Using existing password for root.
Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n
... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.
All done!
3 恢复 sudo mysql 登录，
用客户端的话，跳过这一步。
# 密码登录
mysql -u root -p
# 恢复 sudo mysql 登录
ALTER USER 'root'@'localhost' IDENTIFIED WITH auth_socket;
# 退出
exit
安装 MySQL 客户端：
# 例如，用 MySQL Workbench
sudo snap install mysql-workbench-community
# 或者，用 phpMyAdmin 等
选择 Local 实例，用密码登录，
创建一个名为 casdoor 的数据库，
另外，可创建一个名为 casdoor 的新用户，专门管理该数据库。
获取源码
进工作目录，获取 Casdoor 源码，
# 获取源码
git clone --depth 1 https://github.com/casdoor/casdoor.git
配置
配置位于 casdoor/conf/app.conf，
appname = casdoor
httpport = 8000
runmode = dev
copyrequestbody = true
driverName = mysql
dataSourceName = root:123456@tcp(localhost:3306)/
dbName = casdoor
tableNamePrefix =
showSql = false
redisEndpoint =
defaultStorageProvider =
isCloudIntranet = false
authState = "casdoor"
socks5Proxy = "127.0.0.1:10808"
verificationCodeTimeout = 10
initScore = 2000
logPostOnly = true
origin =
staticBaseUrl = "https://cdn.casbin.org"
isDemoMode = false
batchSize = 100
ldapServerPort = 389
languages = en,zh,es,fr,de,id,ja,ko,ru,vi
quota = {"organization": -1, "user": -1, "application": -1, "provider": -1}
目前先只配置数据库字段 driverName dataSourceName dbName。更多字段说明，见官方文档「服务器安装 / 通过-ini-文件配置」。
运行
开发模式
运行后端：
cd casdoor/
go run main.go
如果发生错误 checksum mismatch，可执行：
go clean -modcache
rm go.sum
go mod tidy
# 还不行，切个代理，再试一次
# 可能代理缓存不一致；可写进 ~/.bashrc
export GOPROXY="https://goproxy.cn,direct"
运行前端：
cd casdoor/web
yarn install
yarn start
访问 http://localhost:7001/，用户 admin 密码 123 登录，
生产模式
运行后端：
cd casdoor/
go build
./casdoor
运行前端：
cd casdoor/web
yarn install
yarn build
容器运行
Docker 准备
Install Docker Desktop on Ubuntu，
$ docker -v
Docker version 23.0.6, build ef23cbc
$ docker compose version
Docker Compose version v2.17.3
Docker 运行
Casdoor 可以使用 docker-compose 运行，它带有独立的数据库，
cd casdoor/
docker compose up
可以如下修改，用本地已有的数据库，
- 编辑
docker-compose.yml- 删掉
services/casdoor下，-
entrypoint里的--createDatabase=true参数 -
depends_on里的db依赖
-
- 删掉
services/db的所有配置
- 删掉
version: '3.1'
services:
casdoor:
restart: always
build:
context: ./
dockerfile: Dockerfile
target: STANDARD
entrypoint: /bin/sh -c './server'
ports:
- "8000:8000"
volumes:
- ./conf:/conf/
- 编辑
Dockerfile删掉ENTRYPOINT ["/server"]之后的 db 内容- 遇到
go build提示版本问题，可修改FROM golang:1.17.5 AS BACK升下版本，如1.20.4 - 遇到
go test不过，- 若下载问题，可命令前加
export GOPROXY="https://goproxy.cn,direct" &&用代理 - 若
TestGetVersionInfoFail，可git pull --unshallow拉取更多 commits 即可
- 若下载问题，可命令前加
- 遇到 apk 安装问题，可以注掉
RUN sed -i 's/https/http/' /etc/apk/repositories - 遇到 yarn fresh packages 永不终止，可以注掉
yarn config set registry https://registry.npmmirror.com
- 遇到
此外，再写个独立的 docker-secret.yaml 来放 services/casdoor 的数据库配置：
version: '3.1'
services:
casdoor:
environment:
driverName: "mysql"
dataSourceName: "casdoor:password@tcp(host.docker.internal:3306)/"
dbName: "casdoor"
最后，
# 运行服务
$ docker compose -f docker-compose.yml -f docker-secret.yml up

结语
Casdoor 这里选择源码方式安装，是考虑做定制化修改；使用容器编译和运行，是考虑发布和部署。
至于 Casdoor 功能如何、怎么使用，要阅读官方文档多做了解，同时也在运行环境里实际玩上一玩。
