Centos上通过shell脚本备份数据库

#!/bin/bash

ds=`date +%s%N|cut -c1-`
list=`date +%Y`/`date +%m`
dname="callme"
eval "mkdir -p $list"

ls_date=`date +%Y%m%d`
echo ${ls_date}
bk="mysqldump -R -E -h 127.0.0.1 -uroot -ppass ${dname} --result-file=${list}/${dname}-${ls_date}.sql"
echo $bk
eval $bk
cd $list
tar -czf callme-${ls_date}.tar.gz *.sql
rm -rf *.sql

cd ../..
mkdir -p logs/$list
cd logs/$list

de=`date +%s%N|cut -c1-`

echo -e "`date +%Y%m%d%H%M%S` 数据备份成功" >> ${dname}.${ls_date}.log
echo -e "Running time:: $((${de}-${ds}))" >> ${dname}.${ls_date}.log
echo -e "Running time:: $((${de}-${ds}))"
