一、expect脚本同步文件
1、编辑同步脚本4.expect
#! /usr/bin/expect
set passwd "root1234"
spawn rsync -av [email protected]:/tmp/hk.txt /tmp #将131 上hk.txt 考到 本地tmp下
expect {
"yes/no" { send "yes\r" }
"password:" { send "$passwd\r" }
}
expect eof
2、给予权限
chmod a+x 4.except
3、expect eof 和 interact
如果注释掉 expect eof，脚本执行不完就会退出，expect eof 和 interact 表示登录成功后停留一段时间，可以执行一些命令。
4、set timeout 的作用
#!/usr/bin/expect
set user [lindex $argv 0]
set host [lindex $argv 1]
set passwd "root1234"
set cm [lindex $argv 2]
spawn ssh $user@$host
expect {
"yes/no" { send "yes\r" }
"password:" { send "$passwd\r" }
}
expect "]*"
send "$cm\r"
set timeout 5 #set timeout 5 设置5秒超时 ，set timeout -1 永久超时
expect "]*"
send "exit\r"
set timeout 要和 expect eof 共同作用
二、指定host和要同步的文件
1、编辑脚本5.expect
#!/usr/bin/expect
set passwd "root1234"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -av $file root@$host:$file #$file 要写绝对路径，从本机考到131 机器
expect {
"yes/no" { send "yes\r" }
"password:" { send "$passwd\r" }
}
expect eof
2、给与权限
三、构建文件分发系统
1、编辑rsync.expect
#!/usr/bin/expect
set passwd "root1234"
set host [lindex $argv 0]
set file [lindex $argv 1] #此处的file 是一个文件列表文件
spawn rsync -avR --files-from=$file / root@$host:/ # 都是根目录
expect {
"yes/no" { send "yes\r" }
"password:" { send "$passwd\r" }
}
expect eof
2、创建文件列表 list.txt
/tmp/hk.txt
/opt/2.log
/root/test.txt
/root/111/ss.txt
3、创建ip.list
192.168.134.131
127.0.0.1
4、创建 rsync.sh
#!/bin/bash
for ip in `cat /opt/ip.txt` #遍历IP
do
./rsync.expect $ip /opt/file.txt
done
5、给予权限
chmod a+x rsync.expect
四、批量远程执行命令
1、创建 exe.expect脚本
#!/usr/bin/expect
set host [lindex $argv 0]
set passwd "root1234"
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"
2、创建exe.sh
#!/bin/bash
for ip in `cat /opt/ip.txt`
do
./exe.expect $ip "hostname"
done
