在CentOS或者Fedora下有时候用yum安装软件的时候最后会提示： 
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID***** 
这是由于yum安装了旧版本的GPG keys造成的，解决办法就是 
rpm --import /etc/pki/rpm-gpg/RPM* 



出现这个Header V4 DSA****NOKEY。的原因是linux的发行版和linux应用软件之间的兼容性出现问题，也就是LSB。 
sudo yum install lsb























IUS（Inline with Upstream Stable）是一个社区项目，它旨在为Linux企业发行版提供可选软件的最新版RPM软件包。

ius源依赖epel源，首先安装epel源
yum install epel-release

centos6
# yum install https://dl.iuscommunity.org/pub/ius/stable/CentOS/6/x86_64/ius-release-1.0-15.ius.centos6.noarch.rpm
centos7
# yum install https://dl.iuscommunity.org/pub/ius/stable/CentOS/7/x86_64/ius-release-1.0-15.ius.centos7.noarch.rpm
使用ius源安装python2.7.x

# yum clean all
# yum install python27
pip 安装
# yum install python27-pip
