Shell (build file distribution System)

1. Requirements background
For large companies, there must be a site or configuration file updates from time to time, and the use of the machine is certainly a lot of units, less than a few, more than dozens of or even hundreds of sets. Therefore, automatic synchronization of files is critical.

2. Realization of Ideas
Start with a template machine, prepare the files to be distributed, and then distribute the files that need to be synchronized to the target machine in batches using the expect script.
3. Core commands
Rsync-av--files-from=list.txt/[Email protected]:/
4. Implementation of the document distribution system
Vim Rsync.expect

#!/usr/bin/expect
Set passwd "123456"
Set host [lindex $ARGV 0]
Set file [lindex $argv 1]
Spawn Rsync-av--files-from= $file/[email protected] $host:/
Expect {
"Yes/no" {send "yes\r"}
"Password:" {send "$passwd \ r"}
}
Expect EOF

(Vim ip.list vim file.list Create IP and file list)

Vim rsync.sh

#!/bin/bash
For IP in ' cat ip.list '
Do
Echo $ip
./rsync.expect $ip List.txt
Done

5. command batch execution script
Vim Exe.expect

#!/usr/bin/expect
Set host [lindex $ARGV 0]
Set passwd "123456"
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"

Vim exe.sh

#!/bin/bash
For IP in ' cat ip.list '
Do
Echo $ip
./exe.expect $ip "W;free-m;ls/tmp"
Done
