通过在shell脚本中用expect实现远程scp文件:
使用expect前,需要先安装两个rpm包:
# rpm -ihv centos/expect-5.43.0-5.1.i386.rpm
# rpm -ihv centos/expect-devel-5.43.0-5.1.i386.rpm
#!/usr/bin/expect -f
set password 密码
spawn scp 用户名@目标机器ip:拷贝文件的路径 存放本地文件的路径
set timeout 300
expect "用户名@目标机器ip's password:" //注意:这里的“用户名@目标机器ip” 跟上面的一致
set timeout 300
send "$password\r"
set timeout 300 //此处设置超时时间,单位为秒,如果,拷贝文件比较大并且多时,应该将这个值调大一些。
send "exit\r"
expect eof
附:scp参数
-r:拷贝目录
-c:允许压缩
一个完整的例子
expect_scp.exp
========================================================================
- #!/usr/bin/expect -f
- #author by kevin
- #date is 2011-11-14
- set password vcdog
- #download local host
- spawn scp -r root@192.168.1.107:/root/dba_tool/test /root/dba_tool/
- set timeout 3
- expect {
- "yes/no" {send "yes\r";exp_continue}
- }
- expect "root@192.168.1.107's password:"
- set timeout 3
- send "$password\r"
- set timeout 300
- send "exit\r"
- expect eof
- #upload remote host
- spawn scp -r /root/dba_tool/t.txt root@192.168.1.107:/root/dba_tool/
- set timeout 3
- expect {
- "yes/no" {send "yes\r";exp_continue}
- }
- expect "root@192.168.1.107's password:"
- set timeout 3
- send "$password\r"
- set timeout 300
- send "exit\r"
- expect eof

测试验证:
# chmod x ./expect_scp.exp
# expect ./expect_scp.exp
spawn scp -r /root/dba_tool/
password:
test 100% 12 0.0kb/s 00:00
spawn scp -r /root/dba_tool/t.txt
password:
t.txt 100% 254 0.3kb/s 00:00
