expect 脚本同步文件，指定host和要同步的文件，构建文件分发系统，批量远程执行命令

Posted 2020-11-01

expect脚本自动同步文件

#!/usr/bin/expect
set passwd "1q2w3e"
spawn rsync -av [email protected]:/tmp/12.txt /tmp/
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof

如果尝试取消最后一行，expect eof

会出现，还没输入密码就退出的情况

/tmp目录下也没文件

指定host和要同步的文件,从本机到对方
#!/usr/bin/expect
set passwd "1q2w3e"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -av $file [email protected]$host:$file
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof

文件分发系统的实现

rsync.expect 内容
#!/usr/bin/expect
set passwd "1q2w3e"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -aRv $file [email protected]$host:$file
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof

ip.list内容
[[email protected] sbin]# cat /tmp/ip.list
192.168.67.129
192.168.67.130
127.0.0.1

file.txt内容
[[email protected] sbin]# cat /tmp/file.txt
/tmp/12.txt
/root/shell/1.sh
/root/111/222/lll.txt

rsync.sh 内容
[[email protected] sbin]# cat rsync.sh
#!/bin/bash
for ip in ‘cat /tmp/ip.list‘
do
./rsync.expect $ip /tmp/file.txt
done
出现问题，暂未解决

发现问题点，修改标点符号，即可。忘了的作用了<br/>#!/bin/bash<br/>for ip incat /tmp/ip.list` * 注意：就是这两个不是单引号的标点符号
do
./rsync.expect $ip /tmp/file.txt
done

实验结果：
[[email protected] sbin]# sh -x rsync.sh
++ cat /tmp/ip.list

• for ip in ‘cat /tmp/ip.list‘
• ./rsync.expect 192.168.67.129 /tmp/file.txt

验证之后发现 文件同步到67.130上了
再同步一次就成功了
[[email protected] sbin]# sh -x rsync.sh

可以到67.129 67.130 验证文件是否同步过去，此处图省略。

exe.expect 执行命令

#!/usr/bin/expect
set host [lindex $argv 0]
set passwd “1q2w3e"
set cm [lindex $argv 1]
spawn ssh [email protected]$host
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect "]"
send "$cm\r"
expect "]"
send "exit\r"

#!/bin/bash
#!/bin/bash
for ip in cat /tmp/ip.list
do
./exe.expect $ip "hostname"
done
