操作步骤
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
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/
# 解压 "data" 目录下的 "data.7z" 压缩包
# 解压 "data" 目录下的 "data.7z" 压缩包
# 上传 "project-spark-shop-maternal-child-data-analysis-sys" 整个文件夹
上传文件到hdfs
cd /data/jobs/project/project-spark-shop-maternal-child-data-analysis-sys/data/
hdfs dfs -mkdir -p /data/input/
hdfs dfs -rm -r /data/input/*
hdfs dfs -put -f sam_tianchi_mum_baby.csv /data/input/
hdfs dfs -put -f sam_tianchi_mum_baby_trade_history.csv /data/input/
hdfs dfs -ls /data/input/
程序打包
cd /data/jobs/project/project-spark-shop-maternal-child-data-analysis-sys/spark_analysis/spark-job/
mvn clean package -Dmaven.test.skip=true
yes | cp target/spark-job-jar-with-dependencies.jar /data/jobs/project/spark-job-jar-with-dependencies.jar
创建MySQL表
cd /data/jobs/project/project-spark-shop-maternal-child-data-analysis-sys/mysql/
# 请确认mysql服务已经启动了
# 快速执行.sql文件内的sql语句
mysql -u root -p < mysql.sql
spark数据清洗
cd /data/jobs/project/
spark-submit \
--master local[*] \
--class com.exam.SparkClean \
/data/jobs/project/spark-job-jar-with-dependencies.jar /data/input/sam_tianchi_mum_baby.csv /data/input/sam_tianchi_mum_baby_trade_history.csv /data/output/trade/ /data/output/baby/
spark数据分析
cd /data/jobs/project/
spark-submit \
--master local[*] \
--class com.exam.SparkApp \
/data/jobs/project/spark-job-jar-with-dependencies.jar /data/output/baby/ /data/output/trade/
启动可视化
cd /data/jobs/project/project-spark-shop-maternal-child-data-analysis-sys/后端/springboot-demo/
mvn clean package -Dmaven.test.skip=true
yes | cp target/springboot-demo-1.0-SNAPSHOT.jar /data/jobs/project/springboot-demo-1.0-SNAPSHOT.jar
# 启动后端 端口: 5173
java -jar /data/jobs/project/springboot-demo-1.0-SNAPSHOT.jar org.apophis.Application
