# **1.expect脚本同步文件** #

使用rsync工具同步文件，脚本如下：

[root@yuioplvlinux-128 sbin]# vim 4.expect
    #!/usr/bin/expect
    set passwd "xxxxxxxx"
    spawn rsync -av root@192.168.30.129:/tmp/12.txt /tmp/
    
    expect {
    "yes/no" { send "yes\r"}
    "password:" { send "$passwd\r" }
    }
    expect eof
    
    [root@yuioplvlinux-128 sbin]# chmod +x 4.expect 
    [root@yuioplvlinux-128 sbin]# ./4.expect 
    spawn rsync -av root@192.168.30.129:/tmp/12.txt /tmp/
    root@192.168.30.129's password: 
    receiving incremental file list
    
    sent 20 bytes  received 45 bytes  130.00 bytes/sec
    total size is 881  speedup is 13.55
    [root@yuioplvlinux-128 sbin]#

# **2.expect脚本指定参数同步文件** #

脚本如下：

[root@yuioplvlinux-128 sbin]# vim 5.expect
    #!/usr/bin/expect
    set passwd "linux-129"
    set host [lindex $argv 0]
    set file [lindex $argv 1]
    spawn rsync -av $file root@$host:$file
    
    expect {
    "yes/no" { send "yes\r"}
    "password:" { send "$passwd\r" }
    }
    expect eof
    [root@yuioplvlinux-128 sbin]# chmod +x 5.expect 
    [root@yuioplvlinux-128 sbin]# ./5.expect 192.168.30.129 /tmp/12.txt
    spawn rsync -av /tmp/12.txt root@192.168.30.129:/tmp/12.txt
    root@192.168.30.129's password: 
    sending incremental file list
    
    sent 45 bytes  received 12 bytes  38.00 bytes/sec
    total size is 881  speedup is 15.46
    [root@yuioplvlinux-128 sbin]#

# **3.构建文件分发系统** #

定义expect脚本和执行的shell脚本，如下：

[root@yuioplvlinux-128 sbin]# vim rsync.expect 
    #!/usr/bin/expect
    set passwd "xxxxxxxx"   #同步主机的密码要与执行脚本的主机密码一致
    set host [lindex $argv 0]
    set file [lindex $argv 1]
    spawn rsync -avR --files-from=$file / root@$host:/
    expect {
    "yes/no" { send "yes\r"}
    "password:" { send "$passwd\r" }
    }
    expect eof
    [root@yuioplvlinux-128 sbin]#vim rsync.sh 
    #!/bin/bash
    for ip in `cat /tmp/ip.list`
    do
        echo $ip
        ./rsync.expect $ip /tmp/file.list
    done

配置要传输的文件列表和要同步的主机IP地址；

[root@yuioplvlinux-128 sbin]# vim /tmp/ip.list 
    192.168.30.129
    192.168.30.130
    [root@yuioplvlinux-128 sbin]# vim /tmp/file.list 
    /root/yu/111/123.txt
    /tmp/12.txt

执行过程如下：

[root@yuioplvlinux-128 sbin]# sh -x rsync.sh 
    ++ cat /tmp/ip.list
    + for ip in '`cat /tmp/ip.list`'
    + echo 192.168.30.129
    192.168.30.129
    + ./rsync.expect 192.168.30.129 /tmp/file.list
    spawn rsync -avR --files-from=/tmp/file.list / root@192.168.30.129:/
    root@192.168.30.129's password: 
    building file list ... done
    
    sent 159 bytes  received 12 bytes  342.00 bytes/sec
    total size is 881  speedup is 1.85
    + for ip in '`cat /tmp/ip.list`'
    + echo 192.168.30.130
    192.168.30.130
    + ./rsync.expect 192.168.30.130 /tmp/file.list
    spawn rsync -avR --files-from=/tmp/file.list / root@192.168.30.130:/
    root@192.168.30.130's password: 
    building file list ... done
    root/
    root/yu/
    root/yu/111/
    root/yu/111/123.txt
    tmp/
    tmp/12.txt
    
    sent 1,134 bytes  received 66 bytes  800.00 bytes/sec
    total size is 881  speedup is 0.73

# **4.批量远程执行命令** #

定义的expect脚本如下：

[root@yuioplvlinux-128 sbin]# vim exe.expect
    #!/usr/bin/expect
    set host [lindex $argv 0]
    set passwd "xxxxxxxxxx"
    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"

shell脚本如下，定义了一条命令打印主机名；

[root@yuioplvlinux-128 sbin]# vim exe.sh
    #!/bin/bash
    for ip in `cat /tmp/ip.list`
    do
        ./exe.expect $ip "hostname"
    done

执行过程如下：

[root@yuioplvlinux-128 sbin]# sh exe.sh 
    spawn ssh root@192.168.30.129
    root@192.168.30.129's password: 
    Last login: Fri Jul 20 23:36:15 2018 from 192.168.30.1
    [root@yuioplvlinux-129 ~]# hostname
    yuioplvlinux-129
    [root@yuioplvlinux-129 ~]# spawn ssh root@192.168.30.130
    root@192.168.30.130's password: 
    Last failed login: Fri Jul 20 23:41:21 CST 2018 from 192.168.30.128 on ssh:notty
