expect

自动登录expect脚本

[root@nginx sbin]# cat 1.expect

#!/usr/bin/expect

set host "192.168.211.135"

set passwd "root123"

spawn ssh root@$host

expect {

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

"assword:" { send "$passwd\r" }

}

interact

[root@nginx sbin]#

自动登录后执行命令

[root@nginx sbin]# cat 2.expect

#!/usr/bin/expect

set user "root"

set host "192.168.211.135"

set passwd "root123"

spawn ssh $user@$host

expect {

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

"assword:" { send "$passwd\r" }

}

expect "]*"

send "touch /tmp/12.ext\r"

expect "]*"

send "echo 1212 >/tmp/12.txt\r"

expect "]*"

send "exit\r"

#interact

[root@nginx sbin]#

expect脚本传递参数

[root@nginx sbin]# cat 3.expect

#!/usr/bin/expect

set user [lindex $argv 0]

set host [lindex $argv 1]

set passwd "root123"

set cm [lindex $argv 2]

spawn ssh $user@$host

expect {

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

"password:" { send "$passwd\r" }

}

expect "]*"

send "$cm\r"

expect "]*"

send "exit\r"

[root@nginx sbin]#

[root@nginx sbin]# ./3.expect root 192.168.211.135 "ls /root/"

自动同步文件脚本

[root@nginx sbin]# cat 4.expect

#!/usr/bin/expect

set passwd "root123"

spawn rsync -av root@192.168.211.135:/tmp/12.txt /tmp/

expect {

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

"password:" { send "$passwd\r" }

}

expect eof

[root@nginx sbin]#

构建简易文件分发系统

适用于有多台机器需要同时更新文件

[root@nginx sbin]# cat rsync.expect

#!/usr/bin/expect

set passwd "root123"

set host [lindex $argv 0]

set file [lindex $argv 1]

spawn rsync -av $file root@$host:/

expect {

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

"password:" { send "$passwd\r" }

}

expect eof

[root@nginx sbin]#

[root@nginx sbin]# cat ip.list

192.168.211.135

192.168.211.137

[root@nginx sbin]#

[root@nginx sbin]# cat rsync.sh

#!/bin/bash

for ip in `cat ip.list`

do

echo $ip

[ -x rsync.expect ] || chmod a+x rsync.expect

./rsync.expect $ip ip.list

done

[root@nginx sbin]#

命令批量执行脚本

适用于有多台机器需要批量执行命令

[root@nginx sbin]# cat exe.expect

#!/usr/bin/expect

set host [lindex $argv 0]

set passwd "root123"

set cm [lindex $argv 1]

spawn ssh root@$host

expect {

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

"password:" { send "$passwd\r" }

}

expect "]*"

send "$cm\r"

expect "]*"

send "exit\r"

[root@nginx sbin]#

[root@nginx sbin]# cat ip.list

192.168.211.135

192.168.211.137

[root@nginx sbin]#

[root@nginx sbin]# cat exe.sh

#!/bin/bash

for ip in `cat ip.list`

do

echo $ip

[ -x exe.expect ] || chmod a+x exe.expect

./exe.expect $ip "w;free -m;ls /tmp"

done

[root@nginx sbin]#
