从centos服务器上将数据库备份拷贝到本地

解决此问题要用到expect脚本：

写法如下，注意一定要设置timeout长一点，否则考到一半就停止了：

#!/usr/bin/expect -f

set password ********

set date [exec date "+%Y%m%d"]

#download local host

spawn scp -r root@{IP地址}:/home/{ps-name}/backup/db/production$date.sql /root/db/

set timeout 3

expect {

"yes/no" {send "yes\r";exp_continue}

}

expect "root@{IP地址}'s password:"

set timeout 30

send "$password\r"

set timeout 3000

send "exit\r"

expect eof
