简洁的一键SSH脚本

  这里发一个自己图省事搞的一个批量打通SSH的脚本，可能对于好多朋友也是实用的,是expect+python的一个组合实现,原理非常easy,
使用起来也不复杂,在此还是简单贴出来说说。

noscp.exp

  #!/usr/bin/expect

#noscp.exp

if {$argc<4} {
 puts stderr "Usage: $argv0 localfile  remotefile user passwd "
 exit 1
}

set localfile [ lindex $argv 0 ]
set remotefile  [ lindex $argv 1 ]
set user  [ lindex $argv 2 ]
set pwd  [ lindex $argv 3 ]

set timeout 30

spawn scp ${localfile}  ${user}@${remotefile}

expect {
 "*yes/no" { send "yes\r"; exp_continue }
 "*password:" { send "$pwd\r" }
}

expect eof  

ssh_distribute.py

#!/usr/bin/python

import subprocess
import os

file_dir='/home/hosts'

with open(file_dir) as data:
    for each_line in data.readlines():
        if each_line != '':
            (ip,passwd)=each_line.split(':',2)
            print('./noscp.exp ~/.ssh/authorized_keys '+ip+':~/.ssh '+'root '+passwd.strip('\n'))
            subprocess.Popen('./noscp.exp ~/.ssh/authorized_keys '+ip+':~/.ssh '+'root '+passwd.strip('\n'),shell=True)
          #  subprocess.Popen('./sshkey.exp '+ip+' root '+passwd+' \\| grep ssh-rsa >> ~/.ssh/authorized_keys',shell=True)
        else:
            pass
#subprocess.Popen('chmod 755 ~/.ssh/authorized_keys',shell=True)

ssh_setup.py

#!/usr/bin/python

import subprocess
import os

file_dir='/home/hosts'

with open(file_dir) as data:
    for each_line in data.readlines():
        if each_line != '':
            (ip,passwd)=each_line.split(':',2)
            print('./sshkey.exp '+ip+' root '+passwd.strip('\n')+' | grep ssh-rsa >> ~/.ssh/authorized_keys')
            subprocess.Popen('./sshkey.exp '+ip+' root '+passwd.strip('\n')+' | grep ssh-rsa >> ~/.ssh/authorized_keys',shell=True)
          #  subprocess.Popen('./sshkey.exp '+ip+' root '+passwd+' \\| grep ssh-rsa >> ~/.ssh/authorized_keys',shell=True)
        else:
            pass
subprocess.Popen('chmod 755 ~/.ssh/authorized_keys',shell=True)
#subprocess.Popen('/home/ssh_distribute.py',shell=True) 

sshkey.exp

#!/usr/bin/expect

#sshkey.exp

if {$argc<3} {
 puts stderr "Usage: $argv0 host  user  passwd "
 exit 1
}

set host [ lindex $argv 0 ]
set user  [ lindex $argv 1 ]
set pwd  [ lindex $argv 2 ]

set timeout 30

#spawn ssh  ${user}@${host} "rm -rf ~/.ssh/id_rsa*"
#
#expect {
# "*yes/no" { send "yes\r"; exp_continue }
# "*password:" { send "$pwd\r"; exp_continue  }
#}

spawn ssh  ${user}@${host} "ssh-keygen -t rsa"

expect {
 "*yes/no" { send "yes\r"; exp_continue }
 "*password:" { send "$pwd\r"; exp_continue  }
 "Enter file in which to save the key*" { send "\n\r"; exp_continue }
 "Overwrite*" { send "y\n"; exp_continue }
 "Enter passphrase (empty for no passphrase):" { send "\n\r"; exp_continue }
 "Enter same passphrase again:" { send "\n\r" }
}

spawn ssh  ${user}@${host} "cat ~/.ssh/id_rsa.pub"

expect {
 "*yes/no" { send "yes\r"; exp_continue }
 "*password:" { send "$pwd\r"  }
}

expect eof

   多看两眼代码应该能够看出,expect的功能是能够等待一些Linux反馈 通过这个的反馈做出推断并能够分类进行兴许的动作，非常黄非常暴力。

也就是利用了这个原理。过程例如以下:
   1.首先运行 ./ssh_setup.py 首先收集全部机器的公钥,然后定向到运行这个脚本的authorized_keys文件中边,自己主动赋予755权限。
   2.运行./ssh_distribute.py 分发authorized_keys文件到全部的机器上。
