scp 不能在 vagrant box 中使用 bash 脚本

Question

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

我的盒子运行良好，所以在 vagrantfile 中我添加了运行外部 shell 脚本。该脚本包含此命令。

custom.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，它可以正常运行，没有任何问题，但不能从 bash 脚本运行。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

Answer 1

我不使用 sshpass（在脚本中明文设置密码的想法让我感到畏缩），但手册页似乎建议在脚本中设置变量 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 .

Answer 2

sshpass 仅在提示以assword: 结尾时有效。在您的情况下，它将是 password for user@test01.admin.com，因为您指定了用户名。

见http://sourceforge.net/p/sshpass/code/HEAD/tree/trunk/main.c第362行

你为什么不改用public key autentication？
