使用hadoop平臺進行小型網站日志分析
0.上傳日志文件到linux中,通過flume將文件收集到hdfs中。
執行命令/home/cloud/flume/bin/flume-ng agent -n a4 -c conf -f /home/cloud/flume/conf/a4.conf -Dflume.root.logger=DEBUG,console
1.建立hive表
create external table bbslog (ip string,logtime string,url string) partitioned by (logdate string) row format delimited fields terminated by '\t' location '/cleaned';
2.創建shell腳本
touch daily.sh
添加執行權限
chmod +x daily.sh
daily.sh:
CURRENT=date +%Y%m%d
對數據進行清理,保存到cleaned文件夾,按照當前日期進行保存
/home/cloud/hadoop/bin/hadoop jar /home/cloud/cleaner.jar /flume/$CURRENT /cleaned/$CURRENT
修改hive表,添加當前日期的分區
/home/cloud/hive/bin/hive -e "alter table bbslog add partition (logdate=$CURRENT) location 'cleaned/$CURRENT'"
使用hive進行分析,根據業務需求而定
統計pv并計入每日的pv表
/home/cloud/hive/bin/hive -e "create table pv_$CURRENT row format delimited fields terminated by '\t' as select count(*) from bbslog where logdate=$CURRENT;"
統計點擊次數過20的潛在用戶
/home/cloud/hive/bin/hive -e "create table vip _$CURRENT row format delimited fields terminated by '\t' as select $CURRENT,ip,count(*) as hits from bbslog where logdate=$CURRENT group by ip having hits > 20 order by hits desc"
查詢uv
/home/cloud/hive/bin/hive -e "create table uv_$CURRENT row format delimited fields terminated by '\t' as select count(distinct ip) from bbslog where logdate=$CURRENT"
查詢每天的注冊人數
/home/cloud/hive/bin/hive -e "create table reg_$CURRENT row format delimited fields terminated by '\t' as select count(*) from bbslog where logdate=$CURRENT AND instr(url,'member.php?mod=register')>0"
將hive表中的數據導入mysql
/home/cloud/sqoop/bin/sqoop export --connect jdbc:mysql://cloud3:3306/jchubby --username root --password JChubby123 --export-dir "/user/hive/warehouse/vip_$CURRENT" --table vip --fields-terminated-by '\t'
