前言

sshpass是ansible密码输入的必要条件，在Linux中使用yum install sshpass或者apt-get install sshpass都可以轻松安装，但在macOS新版本中由于安全原因无法直接使用brew install sshpass，需要采用其它安全的办法绕过。

使用sshpass的场景

在macOS下使用ansible命令(inventory文件中使用了密码验证的方式)或者使用iTerm2来完成自动密码填充等场景会使用到sshpass。
比如下面的样例：Inventory文件中使用了ansible_ssh_pass选项

  1. # 编辑inventory
  2. cat hosts
  3. 10.10.66.66 ansible_port=22 ansible_user=root ansible_ssh_pass=test666
  5. # 使用ansible命令会失败，提示缺少sshpass
  6. ansible all -i test.hosts  -m ping
  7. 10.10.66.66 | FAILED! => {
  8.     "failed": true,
  9.     "msg": "to use the 'ssh' connection type with passwords, you must install the sshpass program"
  10. }

安装sshpass及各种常见小问题处理

直接brew install会提示不安全，被拒绝，brew install —force强制安装也不行

可以通过如下方法进行安装

  1. # 先将文件下载至本地，然后执行安装命令
  2. ❯ wget https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb
  4. # 执行如下命令虽然提示了一个错误，但是也顺利安装成功了
  5. ❯ brew install  sshpass.rb
  6. Error: Failed to load cask: sshpass.rb
  7. Cask 'sshpass' is unreadable: wrong constant name #<Class:0x00007fb25716b2d0>
  8. Warning: Treating sshpass.rb as a formula.

可能会由于网络问题，导致无法直接下载sshpass.rb，所以贴上脚本源码

  1. cat >> sshpass.rb <<EOF
  2. require 'formula'
  4. class Sshpass < Formula
  5.   url 'http://sourceforge.net/projects/sshpass/files/sshpass/1.06/sshpass-1.06.tar.gz'
  6.   homepage 'http://sourceforge.net/projects/sshpass'

  9.   def install
  10.     system "./configure", "--disable-debug", "--disable-dependency-tracking",
  11.                           "--prefix=#{prefix}"
  12.     system "make install"
  13.   end
  15.   def test
  16.     system "sshpass"
  17.   end
  18. end
  19. EOF
