Centos7安装可视化工具Superset1.2.0(含中文配置)

1. 安装superset的依赖

[root@bigdata005 ~]# 
[root@bigdata005 ~]# yum install -y libffi-devel gcc-c++
[root@bigdata005 ~]#

2. 安装python

这里我们安装两个python

1. python3.9.6为服务器的python3环境
2. 因为Superset1.2.0需要python3.7, 所以我们安装python3.7.11作为virtualenv的引用python3环境，但python3.7.11不设置系统软链接

• python3的安装可以参考我的centos7同时安装Python2和Python3

3. 安装Superset的python3.7虚拟环境

1. 安装virtualenv

[root@bigdata005 python3]# 
[root@bigdata005 python3]# pip3 install --upgrade pip
[root@bigdata005 python3]#
[root@bigdata005 python3]# pip3 install virtualenv
[root@bigdata005 python3]#

2. 用virtualenv虚拟superset的python环境

[root@bigdata005 python3]# 
[root@bigdata005 python3]# /opt/python3/python-3.9.6/bin/virtualenv superset --python=/opt/python3/python-3.7.11/bin/python3.7
[root@bigdata005 python3]#

会在当前目录生成虚拟的python3.7环境目录superset

3. 进入superset虚拟环境

[root@bigdata005 python3]# 
[root@bigdata005 python3]# . /opt/python3/superset/bin/activate
(superset) [root@bigdata005 python3]#

• 此时安装和卸载python的包，都只影响虚拟环境
• 可以使用deactivate退出虚拟环境

4. 安装mysql客户端、在mysql中创建superset元数据库

1. 安装mysql客户端

(superset) [root@bigdata005 python3]# 
(superset) [root@bigdata005 python3]# pip3 install --upgrade pip
(superset) [root@bigdata005 python3]# 
(superset) [root@bigdata005 python3]# pip3 install pymysql
(superset) [root@bigdata005 python3]# 

2. 创建superset元数据库

[root@bigdata005 ~]# 
[root@bigdata005 ~]# mysql -u root -pRoot_123
mysql: [Warning] Using a password on the command line interface can be insecure.

mysql> 
mysql> create database superset;

mysql> 

5. 安装superset

(superset) [root@bigdata005 python3]# 
(superset) [root@bigdata005 python3]# pip3 install apache-superset -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
(superset) [root@bigdata005 python3]#

6. 配置

6.1 superset_config.py

1. 在/root/.bashrc添加PYTHONPATH环境变量

export PYTHONPATH=/opt/python3/superset

2. 在PYTHONPATH下，新增superset_config.py，内容如下：

(superset) [root@bigdata005 superset]# pwd
/opt/python3/superset
(superset) [root@bigdata005 superset]# 
(superset) [root@bigdata005 superset]# touch superset_config.py
(superset) [root@bigdata005 superset]# 
(superset) [root@bigdata005 superset]# vi superset_config.py 
(superset) [root@bigdata005 superset]# 
(superset) [root@bigdata005 superset]# cat superset_config.py 
# Superset specific config
ROW_LIMIT = 5000

SUPERSET_WEBSERVER_PORT = 8088

# Flask App Builder configuration
# Your App secret key
SECRET_KEY = '\2\1thisismyscretkey\1\2\e\y\y\h'

# 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
SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://root:Root_123@bigdata005:3306/superset?charset=utf8'

(superset) [root@bigdata005 superset]# 

• superset的默认参数查看请点这里
• Flask的默认参数查看请点这里

6.2 中文的配置

修改/opt/python3/superset/lib/python3.7/site-packages/superset/config.py文件, 修改内容如下：

BABEL_DEFAULT_LOCALE = "zh"

7. superset初始化相关操作

1. superset数据库初始化

(superset) [root@bigdata005 python3]# 
(superset) [root@bigdata005 python3]# superset db upgrade
(superset) [root@bigdata005 python3]# 

2. 设置Flask的APP为superset

(superset) [root@bigdata005 python3]# 
(superset) [root@bigdata005 python3]# export FLASK_APP=superset
(superset) [root@bigdata005 python3]# 

3. superset管理员用户名初始化

(superset) [root@bigdata005 python3]# 
(superset) [root@bigdata005 python3]# superset fab create-admin
/opt/python3/superset/lib/python3.7/site-packages/pandas/compat/__init__.py:109: UserWarning: Could not import the lzma module. Your installed Python is incomplete. Attempting to use lzma compression will result in a RuntimeError.
  warnings.warn(msg)

4. 加载superset的测试数据、图表、看板
   1. 因为默认会从github上下载测试数据，下载慢且会失败，所以我们从github测试数据地址下载数据
   2. 上传解压到我们的文件服务器上，文件服务器的部署请参考使用Tomcat10.0.10搭建一个文件下载服务器
   3. 文件服务器目录结构如下

[root@bigdata005 download2]# 
[root@bigdata005 download2]# pwd
/opt/tomcat/apache-tomcat-10.0.10/download2
[root@bigdata005 download2]# 
[root@bigdata005 download2]# cd superset/
[root@bigdata005 superset]# 
[root@bigdata005 superset]# ls
examples-data-master  examples-data-master.zip
[root@bigdata005 superset]# 
[root@bigdata005 superset]# cd examples-data-master
[root@bigdata005 examples-data-master]# 
[root@bigdata005 examples-data-master]# ll

[root@bigdata005 examples-data-master]# 

• 4. 修改/opt/python3/superset/lib/python3.7/site-packages/superset/examples/helpers.py，内容如下：

BASE_URL = "http://bigdata005:8090/download2/superset/examples-data-master/"

• 5. 说明：/opt/python3/superset/lib/python3.7/site-packages/superset/examples/configs/datasets/examples目录下xxx.yaml文件中，也有很多github的链接，链接直接打开文件而不是下载；链接的父地址也打不开；链接文件的内容和上面下载的examples-data目录的内容不一样；所以只能多次执行superset load_examples解决
  6. 执行测试数据加载命令superset load_examples

5. superset初始化

(superset) [root@bigdata005 python3]#
(superset) [root@bigdata005 python3]# superset init
(superset) [root@bigdata005 python3]#

8. 启动

(superset) [root@bigdata005 python3]# 
(superset) [root@bigdata005 python3]# nohup superset run -h 0.0.0.0 -p 8088 --with-threads --reload >> /opt/python3/superset/superset.log 2>&1 &
[1] 17930
(superset) [root@bigdata005 python3]# 

9. 查看web页面
