=========================== Superset安装部署 =============================================================================
==========================================================================================================================
1、安装python环境
superset运行要求python3.6环境
1）安装miniconda
下载地址：https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
2）安装miniconda
sh Miniconda3-latest-Linux-x86_64.sh
是否每次登陆自动激活base环境：conda config --set auto_activate_base false
3）创建python3.6环境
配置conda国内镜像
bin/conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free
bin/conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
bin/conda config --set show_channel_urls yes
创建python3.6环境
bin/conda create --name superset python=3.6
附件：
conda环境管理命令
创建环境：conda create -n env_name
查看所有环境：conda info -envs
删除环境: conda remove -n env_name --all
4）激活superset环境：
bin/conda activate superset
停止superset环境：
bin/conda deactivate
5）查看python版本信息
(superset) [root@chavin miniconda3]# python
Python 3.6.10 |Anaconda, Inc.| (default, Mar 25 2020, 23:51:54)
[GCC 7.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
2、安装superset
1）安装superset环境依赖
sudo yum upgrade python-setuptools
sudo yum install gcc gcc-c++ libffi-devel python-devel python-pip python-wheel openssl-devel cyrus-sasl-devel openldap-devel
2）通过获取最新的pip 和setuptools库，将所有机会都放在您的身边。：
bin/pip install --upgrade setuptools pip -i https://pypi.douban.com/simple/
3）安装superset ：依赖较多，可能较慢
bin/pip install apache-superset -i https://pypi.douban.com/simple/
4）编写superset配置文件，主要更改元数据配置信息
a)配置python环境变量：
$ vim ~/.bash_profile
PYTHONPATH="/opt/miniconda3/conf:{$PYTHONPATH}"
export PYTHONPATH
b)编写配置文件
$ vim /opt/miniconda/conf/superset_config.py
#---------------------------------------------------------
# Superset specific config
#---------------------------------------------------------
ROW_LIMIT = 5000
SUPERSET_WEBSERVER_PORT = 8088
#---------------------------------------------------------
#---------------------------------------------------------
# Flask App Builder configuration
#---------------------------------------------------------
# Your App secret key
SECRET_KEY = '21thisismyscretkey12eyyh'
# The SQLAlchemy connection string to your database backend
# This connection defines the path to the database that stores your
# superset metadata (slices, connections, tables, dashboards, ...).
# Note that the connection information to connect to the datasources
# you want to explore are managed directly in the web UI
# 注释掉默认数据库 ，同时配置mysql元数据库地址
# SQLALCHEMY_DATABASE_URI = 'sqlite:////path/to/superset.db'
SQLALCHEMY_DATABASE_URI = 'mysql://superset:mysql@chavin.king/superset'
# Flask-WTF flag for CSRF
WTF_CSRF_ENABLED = True
# Add endpoints that need to be exempt from CSRF protection
WTF_CSRF_EXEMPT_LIST = []
# A CSRF token that expires in 1 year
WTF_CSRF_TIME_LIMIT = 60 * 60 * 24 * 365
# Set this API key to enable Mapbox visualizations
MAPBOX_API_KEY = ''
5）初始化数据库
a）首先对接mysql数据源：
bin/conda install mysqlclient
b）执行superset初始化
bin/superset db upgrade
附加 - 此处可能报错如下：

ModuleNotFoundError: No module named 'MySQLdb'
解决办法 - bin/pip install mysqlclient
6）创建管理员用户
export FLASK_APP=superset
bin/superset fab create-admin
7）初始化superset
bin/superset init
8）启动superset
a）安装gunicorn
bin/pip install gunicorn -i https://pypi.douban.com/simple/
b）启动superset ，确保当前环境为superset
bin/gunicorn --workers 2 --timeout 120 --bind chavin.king:8088 "superset.app:create_app()"
--workers : 指定进程个数
--timeout ：worker进程超时时间，超时会自动重启
--bind : 绑定本机地址 ，即superset访问地址
或者
bin/superset run -h 0.0.0.0 -p 8088 --with-threads --reload --debugger
c）停止superset
ps -ef|awk '/gunicorn/ %% !/awk/{print $2}' | xargs kill -9
d）退出superset
conda deactivate
e）登录superset
