使用Shell脚本提供密码 [英] Provide password using Shell script

问题描述

我已经设置了我的客户&用于无密码登录的服务器. 就像通过将服务器的RSA密钥复制到所有客户端的/root/.ssh/id-rsa.pub进行无密码登录一样.但这是我手动完成的.我喜欢使用Shell脚本自动执行此过程，并通过脚本为计算机提供密码. 如果这个问题解决了，那么我也想使用rsync自动将项目推送到所有服务器. 任何人都可以在这方面帮助我.

I had setup my clients & server for passwordless login. Like passwordless login by copying RSA key of server to all client's /root/.ssh/id-rsa.pub. but this, I have done manually. I like to automate this process using shell script and providing password to the machines through script. If this problem is solved then I also want to use rsync to automate push items to all servers. Can any body help me in this regard.

谢谢

推荐答案

此脚本在Debian(及其衍生产品)计算机中提供，用于分发密钥.它称为ssh-copy-id.您将像这样使用它:

This script comes in Debian (and derivatives) machines, to distribute the keys. It's called ssh-copy-id. You'd use it like this:

ssh-copy-id [-i identity_file] [user@]machine

然后输入密码，复制完成.您只需执行一次，然后可以像往常一样在ssh上使用rsync.

Then you'd enter the password and the copying would be done. You would do this one time only and then could use the rsync over ssh as usual.

#!/bin/sh

# Shell script to install your identity.pub on a remote machine
# Takes the remote machine name as an argument.
# Obviously, the remote machine must accept password authentication,
# or one of the other keys in your ssh-agent, for this to work.

ID_FILE="${HOME}/.ssh/identity.pub"

if [ "-i" = "$1" ]; then
  shift
  # check if we have 2 parameters left, if so the first is the new ID file
  if [ -n "$2" ]; then
    if expr "$1" : ".*\.pub" ; then
      ID_FILE="$1"
    else
      ID_FILE="$1.pub"
    fi
    shift         # and this should leave $1 as the target name
  fi
else
  if [ x$SSH_AUTH_SOCK != x ] ; then
    GET_ID="$GET_ID ssh-add -L"
  fi
fi

if [ -z "`eval $GET_ID`" ] && [ -r "${ID_FILE}" ] ; then
  GET_ID="cat ${ID_FILE}"
fi

if [ -z "`eval $GET_ID`" ]; then
  echo "$0: ERROR: No identities found" >&2
  exit 1
fi

if [ "$#" -lt 1 ] || [ "$1" = "-h" ] || [ "$1" = "--help" ]; then
  echo "Usage: $0 [-i [identity_file]] [user@]machine" >&2
  exit 1
fi

{ eval "$GET_ID" ; } | ssh $1 "umask 077; test -d .ssh || mkdir .ssh ; cat >> .ssh/authorized_keys" || exit 1

cat <<EOF
Now try logging into the machine, with "ssh '$1'", and check in:

  .ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

EOF
