ECS怎样安装 cloud-init

在导入镜像时，为了保证导入的镜像 hostname、NTP 和 Yum 源配置成功，建议您先在实例上安装 cloud-init。目前 cloud-init 支持的系统包括：CentOS、Debian、Fedora、FreeBSD、Gentoo、RHEL（Red Hat Enterprise Linux）、SLES（SUSE Linux Enterprise Server）和 Ubuntu。
本文介绍了如何安装 cloud-init。

前提条件


您的实例中应该已经安装了：

• 
  git：用于下载 cloud-init 源码包。

  
  安装命令：yum install git。

• 
  python2.7：是 cloud-init 运行和安装的基础。

  
  安装命令：yum install python。

• 
  pip：用于安装一些 python2.7 里缺少但是 cloud-init 依赖的库。

  
  安装命令：yum install python-pip。

1. 
   执行以下命令从 cloud-init 官网下载 cloud-init 源码包。[backcolor=transparent]git clone https[backcolor=transparent]:[backcolor=transparent]//git.launchpad.net/cloud-init

1. [backcolor=transparent]cd cloud[backcolor=transparent]-[backcolor=transparent]init

1. [backcolor=transparent]python setup[backcolor=transparent].[backcolor=transparent]py install

安装过程中，如果出现以下信息，表示 Python 缺少 six 和 oauthlib 库。您可以使用 pip 安装 six 库：pip install six。
