2、Mysql目标表结构

CREATE TABLE `yemao_logpy` (
`id` varchar(80) DEFAULT NULL,
`time` varchar(80) DEFAULT NULL,
`url_from` varchar(800) DEFAULT NULL,
`url_current` varchar(800) DEFAULT NULL,
`url_to` varchar(800) DEFAULT NULL,
`options` varchar(800) DEFAULT NULL,
`ip` varchar(100) DEFAULT NULL,
`uid` varchar(80) DEFAULT NULL,
`new_visitor` varchar(8) DEFAULT NULL,
`province` varchar(8) DEFAULT NULL,
`city` varchar(8) DEFAULT NULL,
`site` varchar(80) DEFAULT NULL,
`device` varchar(80) DEFAULT NULL,
`browser` varchar(800) DEFAULT NULL,
`phone` varchar(80) DEFAULT NULL,
`token` varchar(800) DEFAULT NULL,
`dorm` varchar(800) DEFAULT NULL,
`order_phone` varchar(80) DEFAULT NULL,
`order_dormitory` varchar(80) DEFAULT NULL,
`order_amount` varchar(80) DEFAULT NULL,
`order_id` varchar(80) DEFAULT NULL,
`uname` varchar(80) DEFAULT NULL,
`site_id` varchar(80) DEFAULT NULL,
`address` varchar(800) DEFAULT NULL,
`dorm_id` varchar(80) DEFAULT NULL,
`dormentry_id` varchar(80) DEFAULT NULL,
`tag` varchar(800) DEFAULT NULL,
`rid` varchar(80) DEFAULT NULL,
`cart_quantity` varchar(80) DEFAULT NULL,
`response` text,
`paytype` varchar(80) DEFAULT NULL,
`data` text,
`info` varchar(800) DEFAULT NULL,
`status` varchar(80) DEFAULT NULL,
`log_date` int(8) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8
/*!50100 PARTITION BY LIST (log_date)
(PARTITION p0 VALUES IN (0) ENGINE = InnoDB,
PARTITION p20151109 VALUES IN (20151109) ENGINE = InnoDB,
PARTITION p20151110 VALUES IN (20151110) ENGINE = InnoDB,
PARTITION p20151111 VALUES IN (20151111) ENGINE = InnoDB,
PARTITION p20151112 VALUES IN (20151112) ENGINE = InnoDB,
PARTITION p20151113 VALUES IN (20151113) ENGINE = InnoDB,
PARTITION p20151114 VALUES IN (20151114) ENGINE = InnoDB,

PARTITION p20151116 VALUES IN (20151116) ENGINE = InnoDB,
PARTITION p20151117 VALUES IN (20151117) ENGINE = InnoDB) */

3、目标表分区维护的存储过程

CREATE DEFINER=`datahouse`@`%` PROCEDURE `p_ymlogpy_maintain`(IN `v_log_date` int)
BEGIN
DECLARE
v_partition_exists INT;

SELECT
count(1) INTO v_partition_exists
FROM
information_schema.`PARTITIONS`
WHERE
TABLE_SCHEMA = 'logdata'
AND table_name = 'yemao_logpy'
AND partition_name = concat('p',v_log_date);

IF v_partition_exists = 1 THEN
SET @exec_sql=concat("ALTER TABLE logdata.yemao_logpy DROP PARTITION p",v_log_date);
PREPARE stmt FROM @exec_sql;
EXECUTE stmt;
END IF;

SET @exec_sql=concat("ALTER TABLE logdata.yemao_logpy ADD PARTITION (PARTITION p",v_log_date," VALUES IN (",v_log_date,"));");
PREPARE stmt FROM @exec_sql;
EXECUTE stmt;

END

二、运行的python及shell脚本

1、连接mysql数据库的python脚本

[spark@Master Py_logproc]$ cat db.py
import MySQLdb

db_config = {
'host': '120.55.189.188',
'user': 'datahouse',
'passwd': 'DTHS2016',
'port': 3306,
'db': 'logdata',
'charset': 'utf8'
}

def getDB():
try:
conn = MySQLdb.connect(host=db_config['host'],user=db_config['user'],passwd=db_config['passwd'],port=db_config['port'],charset=db_config['charset'])
conn.autocommit(True)
curr = conn.cursor()
curr.execute("SET NAMES utf8");
curr.execute("USE %s" % db_config['db']);

return conn, curr
except MySQLdb.Error,e:
print "Mysql Error %d: %s" % (e.args[0], e.args[1])
return None, None

2、处理JSON数据的python脚本

[spark@Master Py_logproc]$ cat json2mysql_python_recordasarray.py
# -*- encoding:utf-8 -*-
from db import getDB
import json
import warnings
warnings.filterwarnings("ignore")

conn,curr = getDB()

if __name__=="__main__":
import sys
reload(sys)
sys.setdefaultencoding( "utf-8" )

if len(sys.argv)==1:
print "need argv"
else:
print sys.argv

i=0

for json_array in open('/home/spark/opt/Log_Data/Py_logproc/log_tmpdir/yemaopythonlog'):
yemao_array = json.loads(json_array)
for yemao in yemao_array:
if not yemao.has_key('_reason'):

id              =   yemao['id']
time            =   yemao['time']
url_from        =   yemao['url_from']
url_current     =   yemao['url_current']
url_to          =   yemao['url_to']
options         =   yemao['options']
ip              =   yemao['ip']
uid             =   yemao['uid']
new_visitor     =   yemao['new_visitor']
province        =   yemao['province']
city            =   yemao['city']
site            =   yemao['site']
device          =   yemao['device']
browser         =   yemao['browser']
phone           =   yemao['phone']
token           =   yemao['token']
dorm            =   yemao['dorm']
order_phone     =   yemao['order_phone']
order_dormitory =   yemao['order_dormitory']
order_amount    =   yemao['order_amount']
order_id        =   yemao['order_id']
uname           =   yemao['uname']
site_id         =   yemao['site_id']
address         =   yemao['address']
dorm_id         =   yemao['dorm_id']
dormentry_id    =   yemao['dormentry_id']
tag             =   yemao['tag']
rid             =   yemao['rid']
cart_quantity   =   yemao['cart_quantity']
response        =   yemao['response']
paytype         =   yemao['paytype']

if yemao.has_key('data'):
data = yemao['data']
else:
data = '0'

data = '"'+str(data)+'"'

if yemao.has_key('info'):
info = yemao['info']
else:
info = '0'

if yemao.has_key('status'):
status = yemao['status']
else:
status = '0'
log_date        =   int(sys.argv[1])

sql = "insert into yemao_logpy(id,time,url_from,url_current,url_to,options,ip,uid,new_visitor,province,city,site,device,browser,phone,token,dorm,order_phone,order_dormitory,order_amount,order_id,uname,site_id,address,dorm_id,dormentry_id,tag,rid,cart_quantity,response,paytype,data,info,status,log_date) values ('%s',  '%s',  '%s',  '%s', '%s', '%s',  '%s',  '%s',  '%s', '%s', '%s',  '%s',  '%s',  '%s', '%s', '%s',  '%s',  '%s',  '%s', '%s', '%s',  '%s',  '%s',  '%s', '%s', '%s',  '%s',  '%s',  '%s', '%s', '%s',  %s,  '%s',  '%s',%d)" % (id,time,url_from,url_current,url_to,options,ip,uid,new_visitor,province,city,site,device,browser,phone,token,dorm,order_phone,order_dormitory,order_amount,order_id,uname,site_id,address,dorm_id,dormentry_id,tag,rid,cart_quantity,response,paytype,data,info,status,log_date)

print sql

curr.execute(sql)

print i
i += 1
else:
print i
i += 1
print i

curr.close()
conn.close()

print 'yemao_array_python done'
[spark@Master Py_logproc]$

3、定时调度的shell脚本

[spark@Master Py_logproc]$ cat Py_logproc.sh
#/bin/bash
export yesterday=`date -d last-day +%Y%m%d`

cd /home/spark/opt/Log_Data/Py_logproc
for tar in /home/spark/opt/Log_Data/yemao/yemao*$yesterday.tar.gz;
do
tar zxvf $tar -C /home/spark/opt/Log_Data/Py_logproc/log_tmpdir;
grep  -h "\[{.*}\]" /home/spark/opt/Log_Data/Py_logproc/log_tmpdir/*.log >> ./log_tmpdir/yemaopythonlog;
rm -rf /home/spark/opt/Log_Data/Py_logproc/log_tmpdir/*.log
done
#sed -i 's/^.//' yemaolog
#sed -i 's/..$//' yemaolog
/usr/local/mysql/bin/mysql -h120.55.189.188 -udatahouse -pDTHS2016 -e "call logdata.p_ymlogpy_maintain($yesterday);"
python /home/spark/opt/Log_Data/Py_logproc/json2mysql_python_recordasarray.py $yesterday
#/home/spark/opt/hive-1.2.1/bin/hive -e "alter table yemao_log drop if exists partition (log_date=$yesterday);alter table yemao_log add if not exists partition (log_date=$yesterday);load data local inpath '/home/spark/opt/Log_Data/yemao/yemao.dat' into table yemao_log partition (log_date=$yesterday);"
rm -rf /home/spark/opt/Log_Data/Py_logproc/log_tmpdir/yemaopythonlog
[spark@Master Py_logproc]$

由于CSDN编码问题，上面脚本的grep部分应为“grep -h "\[{.*}\]" /home/spark/opt/Log_Data/Py_logproc/log_tmpdir/*.log >> ./log_tmpdir/yemaopythonlog;”

4、手动调度的shell脚本

[spark@Master Py_logproc]$ cat Py_logproc_manual.sh
#/bin/bash
#export yesterday=`date -d last-day +%Y%m%d`

while read yesterday
do
cd /home/spark/opt/Log_Data/Py_logproc
for tar in /home/spark/opt/Log_Data/yemao/yemao*$yesterday.tar.gz;
do
tar zxvf $tar -C /home/spark/opt/Log_Data/Py_logproc/log_tmpdir;
grep  -h "\[{.*}\]" /home/spark/opt/Log_Data/Py_logproc/log_tmpdir/*.log >> ./log_tmpdir/yemaopythonlog;
rm -rf /home/spark/opt/Log_Data/Py_logproc/log_tmpdir/*.log
done
#sed -i 's/^.//' yemaolog
#sed -i 's/..$//' yemaolog
/usr/local/mysql/bin/mysql -h120.55.189.188 -udatahouse -pDTHS2016 -e "call logdata.p_ymlogpy_maintain($yesterday);"
python /home/spark/opt/Log_Data/Py_logproc/json2mysql_python_recordasarray.py $yesterday
#/home/spark/opt/hive-1.2.1/bin/hive -e "alter table yemao_log drop if exists partition (log_date=$yesterday);alter table yemao_log add if not exists partition (log_date=$yesterday);load data local inpath '/home/spark/opt/Log_Data/yemao/yemao.dat' into table yemao_log partition (log_date=$yesterday);"
rm -rf /home/spark/opt/Log_Data/Py_logproc/log_tmpdir/yemaopythonlog
done  < /home/spark/opt/Log_Data/Py_logproc/date.list

由于CSDN编码问题，上面脚本的grep部分应为“grep -h "\[{.*}\]" /home/spark/opt/Log_Data/Py_logproc/log_tmpdir/*.log >> ./log_tmpdir/yemaopythonlog;”

日期列表数据内容：

[spark@Master Py_logproc]$ cat date.list
20151109
20151110
20151111
20151112
20151113
20151114
20151115
20151116
20151117
20151118
20151119
[spark@Master Py_logproc]$

三、其他说明

1、在json2mysql_python_recordasarray.py脚本上包含参数传递的内容，数据最终通过Py_logproc.sh脚本的yesterday传递进去。

2、在json2mysql_python_recordasarray.py脚本中添加了 sys.setdefaultencoding( "utf-8" )字符集转换部分，强制成utf8。

3、自动调度的脚本放在crontab中调度，供每日数据跑批；手动调度脚本可在日期列表中定义日期，用于补跑历史日志数据。

4、手动调度的时候可以使用“nohup sh Py_logproc_manual.sh &”，退出xshell客户端不影响正在运行的程序；查看程序是否正在执行使用“ps -ef |grep Py_logproc_manual”；查看输出日志查看当前文件夹下新生成的nohup.out，或实时刷新查看使用“tail -f 100 nohup.out”。

5、目录log_tmpdir用于临时存放数据用，程序执行结束会将临时数据删除。
