ssh 用户名密码登录

ssh不允许用户名密码登录的，然后大神告诉我有个expect可以实现。

安装expect

ubuntu的安装，别的请自己百度

apt-get install expect

使用

大神当然有demo,嘿嘿，拿来直接用
传送门https://github.com/wuhp/tools/tree/master/script
粘过来一个：
./remote_bash [ip] [user] [passwd] “[cmd]”
在远程主机ip上以用户名user密码passwd登录并执行xxx命令

#!/usr/bin/expect -f

# Usage:
#   ./remote_bash [ip] [user] [passwd] "[cmd]"

# In this case, the command line beginner should like '[root@localhost node]# ', ending with ']# '

if { $argc != 4 } {
  send_user "usage: $argv0 ip user passwd cmd\n"
  exit
}

set ip [lindex $argv 0]
set user [lindex $argv 1]
set password [lindex $argv 2]
set cmd [lindex $argv 3]
set timeout -1

spawn ssh $user@$ip
expect {
  "*yes/no" { send "yes\r"; exp_continue }
  "*password:" { send "$password\r" }
}

expect "*# "
send "$cmd\r"
send  "exit\r"
expect eof

注：倒数第四行可能报错，他匹配的是登录到命令行后的前缀,不是root用户要改成’&’
