1,在mongodb上导出数据,写个脚步expmongo.sh,shell脚本如下
#!/bin/sh
datestr=`date '+%Y-%m-%d'`
/usr/local/mongodb/mongodb-linux-x86_64-2.4.4/bin/mongoexport -im_user -pxxxeedd -d im -c message -f txnType,issNo,sn,merchantorder,paymentType,paymentTime,authNo,expDate,cardNo,amount,batchNo,refNo,merchantName,voucher,acqNo --csv -o /tmp/im_$datestr.txt && sz /tmp/im_$datestr.txt
导出来的im数据,/tmp/im_$datestr.txt ,大概有6000多条记录。
类似这样的数据:
txnType,issNo,sn,merchantorder,paymentType,paymentTime,authNo,expDate,cardNo,amount,batchNo,refNo,merchantName,voucher,acqNo
“0”,”“,”WP14521000000342”,”“,”银行卡”,”1440050366667”,”“,”“,”6216615625”,”10”,”2”,”891094135928”,”厚味香味馆”,”000235”,””
“1”,,”WP14521000000342”,,,,,,,”10”,,,,,
“0”,”“,”WP14521000000422”,”“,”现金”,”1440050722137”,”“,”“,”“,”0.01”,”“,”“,”老裁缝家纺”,”“,”“
2,在MySQL库里面,建一张存储mongodb的数据的表:
建表语句如下:
CREATE TABLE sap_im (
txnType varchar(8) DEFAULT NULL,
issNo varchar(128) DEFAULT NULL,
sn varchar(128) DEFAULT NULL,
merchantorder varchar(128) DEFAULT NULL,
paymentType varchar(128) DEFAULT NULL,
paymentTime varchar(128) DEFAULT NULL,
authNo varchar(128) DEFAULT NULL,
expDate varchar(128) DEFAULT NULL,
cardNo varchar(128) DEFAULT NULL,
amount varchar(128) DEFAULT NULL,
batchNo varchar(128) DEFAULT NULL,
refNo varchar(128) DEFAULT NULL,
merchantName varchar(128) DEFAULT NULL,
voucher varchar(128) DEFAULT NULL,
acqNo varchar(128) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4
3,导入到mysql里面
上传im_$datestr.txt到mysql服务器,先然后把导出文件改成表名字
mv /tmp/im_detail_2015-11-12.txt /tmp/sap_im.csv
开始导入:
mysql> LOAD DATA INFILE “/tmp/sap_im.csv” REPLACE INTO TABLE sap_im FIELDS TERMINATED BY ‘,’ OPTIONALLY ENCLOSED BY ‘”’ ESCAPED BY ‘”’ LINES TERMINATED BY ‘\r\n’;
Query OK, 1 row affected (0.02 sec)
Records: 1 Deleted: 0 Skipped: 0 Warnings: 0
mysql>
奇怪,这里只导入了第一行记录,估计是换行符的问题,去掉命令行的\r,将’\r\n’换成’\n’即可,如下所示:
mysql>
mysql>
mysql> LOAD DATA INFILE “/tmp/sap_im.csv” REPLACE INTO TABLE sap_im FIELDS TERMINATED BY ‘,’ OPTIONALLY ENCLOSED BY ‘”’ ESCAPED BY ‘”’ LINES TERMINATED BY ‘\n’;
Query OK, 6555 rows affected (1.81 sec)
Records: 6555 Deleted: 0 Skipped: 0 Warnings: 0
mysql>
最终正常导入了6000多条记录出来。
