介绍
安装
- 首先安装自制homebrew安装 管理器，然后运行以下命令：
brew install readline pkg-config libffi openssl mysql postgresql@14
- 配置环境变量
需要设置 LDFLAGS 和 CFLAGS 才能正确构建某些 Python 包。您可以使用以下命令导出这些变量
export LDFLAGS="-L$(brew --prefix openssl)/lib"
export CFLAGS="-I$(brew --prefix openssl)/include"
- 克隆代码到本地
git clone https://github.com/apache/superset.git
cd superset
- 安装
# Create a virtual environment and activate it (recommended)
python3 -m venv venv # setup a python3 virtualenv
source venv/bin/activate
# Install external dependencies
pip install -r requirements/testing.txt
# Install Superset in editable (development) mode
pip install -e .
# Initialize the database
superset db upgrade
# Create an admin user in your metadata database (use `admin` as username to be able to load the examples)
superset fab create-admin
# Create default roles and permissions
superset init
# Load some data to play with.
# Note: you MUST have previously created an admin user with the username `admin` for this command to work.
superset load-examples #optional
#Before running back-end services, front-end dependencies need to be downloaded and packaged, and js will be automatically loaded when running the back-end service
#install node
brew install node
#Install the domestic image source
npm install -g cnpm --registry=https://registry.npm.taobao.org
#install client dependencies
cd superset-frontend
cnpm i
# Start the Flask dev web server from inside your virtualenv.
# Note that your page may not have CSS at this point.
# See instructions below how to build the front-end assets.
superset run -p 8088 --reload --debugger --debug
安装运行遇到的问题
1. 执行superset load-examples报错需要证书才能拉下来
2. 执行superset安装时需要配置SUPERSET_SECRET_KEY环境变量，不然拒绝加载服务
更多详情参考官方超级配置集
# Flask App Builder configuration
# Your App secret key will be used for securely signing the session cookie
# and encrypting sensitive information on the database
# Make sure you are changing this key for your deployment with a strong key.
# Alternatively you can set it with `SUPERSET_SECRET_KEY` environment variable.
# You MUST set this for production environments or the server will not refuse
# to start and you will see an error in the logs accordingly.
SECRET_KEY = 'YOUR_OWN_RANDOM_GENERATED_SECRET_KEY'
解决方式1:
#生成加密密钥
openssl rand -base64 42
#使用openssl生成的密钥，临时加载环境变量
export SUPERSET_SECRET_KEY='xxxxxxxxx'
解决方式2:
自行在 superset/config.py配置SUPERSET_SECRET_KEY
替换本地mysql
#安装pymysql依赖
pip install pymysql
修改 superset/config.py的mysql连接
注意事项：连接mysql 8.0以上报错
pymysql.err.OperationalError: (2003, "Can't connect to MySQL server on 'localhost' ([Errno 61] Connection refused)")
原因分析：
方式一：
修改vim /etc/my.cnf
重启mysql
brew services restart mysql
方式二：
在pymysql连接时加上unix_socket=/tmp/mysql.sock，如上图
