linux 多台主机配置 ssh 互信脚本 -m6米乐安卓版下载

互信是指配置免密登录另一台主机，常用于自动化脚本！

以下分享个互信脚本：

dest_user=$1
  password=$2
  hosts_file=$3
  if [ $# -ne 3 ]; then
    echo "usage:"
    echo "$0 remoteuser remotepassword hostsfile"
    exit 1
  fi
  if [ "${dest_user}" != "root" ]; then
    cd /home/"${dest_user}"/ || return
  fi
  ssh_dir=~/.ssh
  script_prefix=./tmp
  echo ===========================
  # 1. prepare  directory .ssh
  mkdir $ssh_dir
  chmod 700 $ssh_dir
  # 2. generat ssh key
  tmp_script=$script_prefix.sh
  {
    echo "#!/usr/bin/expect"
    echo "spawn ssh-keygen -b 1024 -t rsa"
    echo "expect *key*"
    echo "send \r"
  } >>$tmp_script
  if [ -f $ssh_dir/id_rsa ]; then
    {
      echo "expect *verwrite*"
      echo "send y\r"
    } >>$tmp_script
  fi
  {
    echo "expect *passphrase*"
    echo "send \r"
    echo "expect *again:"
    echo "send \r"
    echo "interact"
  } >>$tmp_script
  chmod  x $tmp_script
  /usr/bin/expect $tmp_script
  rm -rf $tmp_script
  # 3. generat file authorized_keys
  cat $ssh_dir/id_rsa.pub >>$ssh_dir/authorized_keys
  # 4. chmod 600 for file authorized_keys
  chmod 600 $ssh_dir/authorized_keys
  echo ===========================
  # 5. copy all files to other hosts
  for ip in $(<"${hosts_file}"); do
    if [ "x$ip" != "x" ]; then
      echo -------------------------
      tmp_script=${script_prefix}.$ip.sh
      # check known_hosts
      val=$(ssh-keygen -f "${ip}")
      if [ "x$val" == "x" ]; then
        echo "$ip not in $ssh_dir/known_hosts, need to add"
        val=$(ssh-keyscan "${ip}" 2>/dev/null)
        if [ "x$val" == "x" ]; then
          echo "ssh-keyscan $ip failed!"
        else
          echo "${val}" >>$ssh_dir/known_hosts
        fi
      fi
      echo "copy $ssh_dir to $ip"
      {
        echo "#!/usr/bin/expect"
        echo "spawn scp -r  $ssh_dir $dest_user@$ip:~/"
        echo "expect *assword*"
        echo "send $password\r"
        echo "interact"
      } >"$tmp_script"
      chmod  x "$tmp_script"
      /usr/bin/expect "$tmp_script"
      rm -rf "$tmp_script"
      echo "copy done."
    fi
  done
  # 6. date ssh
  for ip in $(<"$hosts_file"); do
    if [ "x$ip" != "x" ]; then
      {
        echo "#!/usr/bin/expect"
        echo "spawn ssh $dest_user@$ip date"
        echo "expect *yes*"
        echo "send yes\r"
        echo "interact"
      } >"$tmp_script"
      chmod  x "$tmp_script"
      /usr/bin/expect "$tmp_script"
      rm -rf "$tmp_script"
      echo "copy done."
    fi
  done

创建一个脚本 sshtrust.sh，将以上内容写入脚本！

支持多台主机进行互信，创建一个 sshhostlist.cfg 文件，将需要配置互信的主机ip写入：

10.211.55.100
10.211.55.101
10.211.55.102

执行如下命令互信：

sh sshtrust.sh 互信用户 互信用户密码 sshhostlist.cfg

执行完成后，即配置互信成功！
