啟動MySQL
# 查看mysql是否啟動 啟動命令: systemctl start mysqld.service
systemctl status mysqld.service
# 進入mysql終端
# MySQL的用戶名:root 密碼:123456
# MySQL的用戶名:root 密碼:123456
# MySQL的用戶名:root 密碼:123456
mysql -uroot -p123456
啟動Hadoop
# 離開安全模式: hdfs dfsadmin -safemode leave
# 啟動hadoop
bash /export/software/hadoop-3.2.0/sbin/start-hadoop.sh
準備目錄
mkdir -p /data/jobs/project/
cd /data/jobs/project/
# 上傳 "project-spark-market-data-analysis" 整個文件夾
上傳文件到hdfs
cd /data/jobs/project/project-spark-market-data-analysis/
hdfs dfs -mkdir -p /data/input/
hdfs dfs -rm -r /data/input/*
hdfs dfs -put -f data/market_sale_order.csv /data/input/
hdfs dfs -put -f data/market_sale_persons.csv /data/input/
hdfs dfs -put -f data/market_sale_return.csv /data/input/
hdfs dfs -ls /data/input/
程序打包
cd /data/jobs/project/project-spark-market-data-analysis/
mvn clean package -Dmaven.test.skip=true
cp target/project-spark-market-data-analysis-jar-with-dependencies.jar /data/jobs/project/
創(chuàng)建MySQL表
cd /data/jobs/project/project-spark-market-data-analysis/
# 請確認mysql服務(wù)已經(jīng)啟動了
