linux - scp 无法从 vagrant box 中的 bash 脚本运行

Question

我正在使用 vagrant 1.6.3 版本和 vagrant 的默认 linux box。

我的盒子运行良好，所以我在 vagrantfile 中添加了一个外部 shell 脚本。该脚本包含此命令。

自定义.sh文件

#!/bin/bash

DEPLOY_PASSWORD="xxxxx" &&
DB_NAME="test-sync.sql.gz" &&
apt-get install sshpass &&
sshpass -p "$DEPLOY_PASSWORD" scp -P 22 -v user@test01.admin.com:"~/mysql_dumps/$DB_NAME" "./"

我尝试手动运行该命令，它运行良好，没有任何问题，但它不适用于 bash 脚本。这是我通过运行 vagrant provision 得到的错误日志:

 The following SSH command responded with a non-zero exit status.
 Vagrant assumes that this means the command failed!
 chmod +x /tmp/vagrant-shell && /tmp/vagrant-shell test-sync.sql.gz

我不使用 sshpass(在脚本中使用明文密码的想法让我感到畏缩)，但手册页似乎建议在脚本中你应该设置变量 SSHPASS 而不是使用-p 咒语……

EXAMPLES
   Run rsync over SSH using password authentication, passing the password on the command line:
   rsync --rsh='sshpass -p 12345 ssh -l test' host.example.com:path .
   To do the same from a bourne shell script in a marginally less exposed way:
   SSHPASS=12345 rsync --rsh='sshpass -e ssh -l test' host.example.com:path .
