3. Redhat 7 如何设置DNS
   编辑文件 /etc/sysconfig/network-scripts/ifcfg-eth0
   修改其中的PEERDNS项
   PEERDNS="no"

然后增加DNS，如：
DNS1="10.184.13.14"
DNS2="10.184.13.4"

重启系统后，文件/etc/resolv.conf中会自动增加DNS配置（如只在此文件中配置DNS，重启后会丢失）

4.Install CFN script for Centos7

#!/bin/bash  
# Setup CentOS 7 host as AMI  

# Update base OS update, and install EPEL repo and Python Pip  
sudo yum -y update  
sudo yum –y install epel-release  
sudo yum -y install python-pip  

# Install Python add-ons:  
sudo pip install pystache   
sudo pip install argparse  
sudo pip install python-daemon  
sudo pip install requests  

# Install CFN-BootStrap from source  
curl -sSL https://s3.amazonaws.com/cloudformation-examples/aws-cfn-bootstrap-latest.tar.gz | sudo tar -xpf -C - /opt  
cd /opt/aws-cfn-bootstrap-1.4/  
sudo python setup.py build  
sudo python setup.py install  
# Configure CFN  
sudo ln -s /usr/init/redhat/cfn-hup /etc/init.d/cfn-hup  
sudo chmod 775 /usr/init/redhat/cfn-hup  
cd /opt  
sudo mkdir aws  
cd aws  
sudo mkdir bin  
ln -s /usr/bin/cfn-hup /opt/aws/bin/cfn-hup

用easy_install更简单：

# easy_install --script-dir /opt/aws/bin https://s3.amazonaws.com/cloudformation-examples/aws-cfn-bootstrap-latest.tar.gz

安装新版本的easy_install

# curl -O https://bootstrap.pypa.io/ez_setup.py
# python ez_setup.py
