expect 脚本同步文件
- [root@centos7-3 shell]# vi 1.expect
- #!/usr/bin/expect
- set passwd "123456"
- spawn rsync -av root@192.168.1.83:/tmp/12.txt /tmp/
- expect {
- "yes/no" { send "yes\r"}
- "password:" { send "$passwd\r" }
- }
- expect eof
- [root@centos7-3 shell]# chmod +x 1.expect
执行:
说明: expect eof 的作用是等待脚本中的命令执行完后再退出
expect 脚本指定 host 和要同步的文件
- [root@centos7-3 shell]# vi 2.expect
- #!/usr/bin/expect
- set passwd "123456"
- 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@centos7-3 shell]# chmod a+x 2.expect
- [root@centos7-3 shell]# touch /tmp/3.txt
- [root@centos7-3 shell]# ./2.expect 192.168.1.83 "/tmp/3.txt"
- spawn rsync -av /tmp/3.txt root@192.168.1.83:/tmp/3.txt
- root@192.168.1.83s password:
- sending incremental file list
- 3.txt
- sent 69 bytes received 31 bytes 66.67 bytes/sec
注: 本脚本只能同步一个文件
构建文件分发系统
首先要有一台模板机器, 把要分发的文件准备好, 然后只要使用 expect 脚本批量把需要同步的文件分发到目标机器即可 (把多个文件分发到多台机器时需要创建文件 IP 列表, 即本文中的 list.txtiplist.txt)
创建 分发系统
创建一个文件列表文件备用:
- [root@test ~]# vim /tmp/list.txt
- /tmp/12.txt
- /tmp/3.txt
- # 该文件下可以添加多个文件
注意: 此处要保证客户端有同样的目录
创建一个 IP 列表文件备用:
- [root@test ~]# vim /tmp/iplist.txt
- 192.168.1.83
- # 该文件下可以指定多个 IP
创建 rsync.expect 脚本:
- [root@test ~]# vim rsync.expect
- #!/usr/bin/expect
- set passwd "123456"
- 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@test ~]# chmod a+x rsync.expect
- [root@test ~]# vim rsync.sh
- #!/bin/bash
- for ip in `cat /tmp/iplist.txt`
- do
- ./rsync.expect $ip /tmp/list.txt
- done
执行:
- sh -x rsync.sh
- ++ cat /tmp/iplist.txt
- + for ip in `cat /tmp/iplist.txt`
- + ./rsync.expect 192.168.1.48 /tmp/list.txt
- spawn rsync -avR --files-from=/tmp/list.txt / root@192.168.1.48:/
- building file list ... done
- tmp/
- tmp/12.txt
- tmp/3.txt
- sent 163 bytes received 53 bytes 432.00 bytes/sec
- total size is 13 speedup is 0.06
批量远程执行命令
创建 exe.expect
- [root@test ~]# vim exe.expect
- #!/usr/bin/expect
- set host [lindex $argv 0]
- set passwd "123456"
- 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@test ~]# chmod a+x exe.expect
- [root@test ~]# vim exe.sh
- #!/bin/bash
- for ip in `cat /tmp/iplist.txt`
- do
- ./exe.expect $ip "hostname"
- done
执行: sh exe.sh
