前言

这次博客我们就可以完成线上问诊的离线数仓项目。

---

一、全流程调度

正常应该使用DolphinScheduler进行全流程调度，但是由于博主的电脑硬件的极限。所以为了完成整个项目，我们自己写一个bash脚本，来进行流程调度

1.生产新数据

vim /opt/module/maxwell/config.properties

medical_mock.sh 1

在数据库中查看是否出现10号数据。

2.编写脚本

这个脚本是我自己写的，项目中原本没有
vim ~/bin/medical_run.sh

#!/bin/bash 
/bin/bash /home/atguigu/bin/medical_mysql_to_hdfs_full.sh all $1
/bin/bash /home/atguigu/bin/medical_hdfs_to_ods.sh all $1
/bin/bash /home/atguigu/bin/medical_ods_to_dwd.sh all $1
/bin/bash /home/atguigu/bin/medical_ods_to_dim.sh all $1
/bin/bash /home/atguigu/bin/medical_dwd_to_dws_1d.sh all $1
/bin/bash /home/atguigu/bin/medical_dws_1d_to_dws_nd.sh all $1
/bin/bash /home/atguigu/bin/medical_dws_1d_to_dws_td.sh all $1
/bin/bash /home/atguigu/bin/medical_dws_to_ads.sh all $1
/bin/bash /home/atguigu/bin/medical_hdfs_to_mysql.sh all

添加权限
chmod +x ~/bin/medical_run.sh

3.脚本测试

先打开之前创建的所有通道

myhadoop.sh start
zk.sh start
kf.sh start
mxw.sh start
medical-f1.sh start
hiveservices.sh start

medical_run.sh 2023-05-10

当数据库中出现10号，代表成功。

二、可视化展示

这里我们就不需要通道了，如果硬件不太够，可以把通道关闭。

1.安装Miniconda3

minconda3清华源

bash Miniconda3-latest-Linux-x86_64.sh

安装地址修改一下。
/opt/module/miniconda3
激活环境
source ~/.bashrc
取消默认激活base
conda config --set auto_activate_base false
换源
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
conda config --set show_channel_urls yes

2.安装python3

conda create --name superset python=3.8.16
激活环境
conda activate superset

3.Superset部署

1.安装依赖

sudo yum install -y gcc gcc-c++ libffi-devel python-devel python-pip python-wheel python-setuptools openssl-devel cyrus-sasl-devel openldap-devel

2.加载模块

编写一个base.txt文件

4.Superset部署

1.安装Superset

pip install apache-superset==2.0.0 -i https://pypi.tuna.tsinghua.edu.cn/simple -r base.txt

2.配置Superset元数据库

CREATE DATABASE superset DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
create user superset@'%' identified WITH mysql_native_password BY 'superset';
grant all privileges on *.* to superset@'%' with grant option;
flush privileges;

3.修改superset配置文件

vim /opt/module/miniconda3/envs/superset/lib/python3.8/site-packages/superset/config.py

SQLALCHEMY_DATABASE_URI = ‘mysql://superset:superset@hadoop102:3306/superset?charset=utf8’

4.安装python msyql驱动

conda install mysqlclient

5.初始化superset元数据

export FLASK_APP=superset
superset db upgrade

5.SupersetSet初始化

1.创建管理员用户

superset fab create-admin

密码自己输入一下，其他的默认就行了。

2.初始化superset

superset init

3.启动脚本

pip install gunicorn -i https://pypi.douban.com/simple/
vim ~/bin/superset.sh

#!/bin/bashsuperset_status(){result=`ps -ef | awk '/gunicorn/ && !/awk/{print $2}' | wc -l`if [[ $result -eq 0 ]]; thenreturn 0elsereturn 1fi
}
superset_start(){source ~/.bashrcsuperset_status >/dev/null 2>&1if [[ $? -eq 0 ]]; thenconda activate superset ; gunicorn --workers 5 --timeout 120 --bind hadoop102:8787 --daemon 'superset.app:create_app()'elseecho "superset正在运行"fi}superset_stop(){superset_status >/dev/null 2>&1if [[ $? -eq 0 ]]; thenecho "superset未在运行"elseps -ef | awk '/gunicorn/ && !/awk/{print $2}' | xargs kill -9fi
}case $1 instart )echo "启动Superset"superset_start;;stop )echo "停止Superset"superset_stop;;restart )echo "重启Superset"superset_stopsuperset_start;;status )superset_status >/dev/null 2>&1if [[ $? -eq 0 ]]; thenecho "superset未在运行"elseecho "superset正在运行"fi
esac

添加权限
chmod +x ~/bin/superset.sh
启动superset
superset.sh start
访问http://hadoop102:8787

用之前设置的密码登录。

6.Superset使用

1.连接MYSQL

2.配置Table

用这三张表进行数据可视化。

3.制作仪表盘

可以和数据库数据对比一下。









检查一下数据




自己拖拽三个框

直接拖进去

自己调整一下大小就可以保存了。


把得到的连接复制到浏览器即可使用。
