【新版】bandwagonhost-美国vps主机最新特价版VPS 支持支付宝

bandwagonhos（搬砖工）美国vps主机商，已经没有以前的便宜货出售了，由于目前他们拿不到低价的IPv4，或者说拿不到低价的大量IP，所以接下来都不会再卖之前3.99美元一年的VPS了

进入搬瓦工ClientArea- https://bandwagonhost.com/clientarea.php输入注册的邮箱和密码登录；
点击Services-My Services-点击你需要架设的VPS对应的KiWiVM Control Panel，这样我们就进入VPS的控制面板（在这里可以看到你的VPS的IP和SSH端口等信息）；
点击Stop（停止掉当前的系统）-停止后点击Instal New OS（这个在页面左侧）-进入选择Debian 7 x86，把红字的勾选上，确认，很快你的新系统就安装完成；
新系统安装完成后，搬瓦工会告诉你VPS 新的Root账户密码，以及新的SSH端口，这两项很重要，记下来后面会用到（VPS的root密码可以在Panel里自行设置）。
