操作步骤

python安装包

pip3 install pandas==2.0.3 -i https://mirrors.aliyun.com/pypi/simple/
pip3 install flask==3.0.0 -i https://mirrors.aliyun.com/pypi/simple/
pip3 install flask-cors==4.0.1 -i https://mirrors.aliyun.com/pypi/simple/
pip3 install pymysql==1.1.0 -i https://mirrors.aliyun.com/pypi/simple/
pip3 install pyecharts==2.0.4 -i https://pypi.tuna.tsinghua.edu.cn/simple

启动MySQL

# 查看mysql是否启动 启动命令: systemctl start mysqld.service
systemctl status mysqld.service
# 进入mysql终端
# MySQL的用户名:root 密码:123456
# MySQL的用户名:root 密码:123456
# MySQL的用户名:root 密码:123456
mysql -uroot -p123456

创建MySQL库

CREATE DATABASE IF NOT EXISTS echarts CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

启动Hadoop

# 离开安全模式: hdfs dfsadmin -safemode leave
# 启动hadoop
bash /export/software/hadoop-3.2.0/sbin/start-hadoop.sh

准备目录

mkdir -p /data/jobs/project/
cd /data/jobs/project/# 上传 "project-spark-olympic-gold-medals-analysis" 整个文件夹 到 "/data/jobs/project/" 目录

上传文件到hdfs

cd /data/jobs/project/project-spark-olympic-gold-medals-analysis/datahdfs dfs -mkdir -p /data/input/
hdfs dfs -rm -r /data/input/*
hdfs dfs -put summer.csv /data/input/hdfs dfs -ls /data/input/

程序打包

cd /data/jobs/project/# 对 项目 "project-spark-olympic-gold-medals-analysis" 进行打包
# 打包命令: mvn clean package -Dmaven.test.skip=true
# yes | cp /data/jobs/project/project-spark-olympic-gold-medals-analysis/target/project-spark-olympic-gold-medals-analysis-jar-with-dependencies.jar /data/jobs/project/# 上传 "project-spark-olympic-gold-medals-analysis/target/" 目录下的 "project-spark-olympic-gold-medals-analysis-jar-with-dependencies.jar" 文件 到 "/data/jobs/project/" 目录

spark数据分析

cd /data/jobs/project/spark-submit \
--master local[*] \
--class org.example.demo.CleanCsv \
/data/jobs/project/project-spark-olympic-gold-medals-analysis-jar-with-dependencies.jar /data/input/ /data/output/

启动可视化

cd /data/jobs/project/project-spark-olympic-gold-medals-analysis/可视化/flaskProject/# windows本地运行: python app.py
python3 app.py pro
