shell中写了简单的一段
energy.sh内容：
#!/bin/bash host=127.0.0.1 user=****** passwd=****** dbname=****** tablename=device_value_300sct007p01_year MONTH=$(date +%Y-%m) sqlstr="insert into device_value_300sct007p01_year (id,year,month,device_id,device_value_id,value,type) select replace(uuid(), ‘-‘, ‘‘),substring(month,1,4),month,device_id,device_value_id,sum(value),type from device_value_300sct007p01_month where month = ${MONTH} group by month,device_id,device_value_id" mysql -h $host -u$user -p$passwd -D $dbname -e ‘select * from device_value_300sct007p01_year‘
最简单的一个查询，就是报错‘@‘localhost‘ (using password: YES)‘root ，用户名密码都正确
最后发现原因：多了\r，脚本是在windows下写的，由于windows和linux换行符不一致导致
sh -x energy.sh
+ host=$‘127.0.0.1\r‘ + user=$‘******\r‘ + passwd=$‘******\r‘ + dbname=$‘******\r‘ + tablename=$‘device_value_300sct007p01_year\r‘ ++ date +%Y-%m + MONTH=$‘2015-03\r‘ + sqlstr=‘insert into device_value_300sct007p01_year (id,year,month,device_id,device_value_id,value,type) select replace(uuid(), ‘\‘‘-‘\‘‘, ‘\‘‘‘\‘‘),substring(month,1,4),month,device_id,devi‘group by month,device_id,device_value_idalue_300sct007p01_month where month = 2015-03 ++ -h $‘127.0.0.1\r‘ $‘-uroot\r‘ $‘-pyunho201311\r‘ -D $‘xcloud\r‘ -e ‘select * from device_value_300sct007p01_year‘ energy.sh: line 9: -h: command not found + mysql $‘\r‘ ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: NO)
每个变量后都多了\r，导致用户名密码错误
解决方法：
删除文件中的\r
tr -d "\r" <energy.sh >energy1.sh
再次运行
sh energy1.sh
