pyenv#可以实现python多版本控制与切换
ipython#更方便的编写python，可以补全命令彩色显示等功能
yum -y install gcc gcc-c++ make git patch openssl-devel zlib-devel readline-devel sqlite-devel bzip2-devel
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
echo ‘export PYENV_ROOT="$HOME/.pyenv"‘ >> ~/.bashrc
echo ‘export PATH="$PYENV_ROOT/bin:$PATH"‘ >> ~/.bashrc
echo ‘eval "$(pyenv init -)"‘ >> ~/.bashrc exec $SHELL -l
yum -y install ipython
git clone git://github.com/yyuu/pyenv.git .pyenv
3、配置环境变量：
vim /etc/profile.d/pyenv.sh
添加内容：
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
if which pyenv > /dev/null; then eval "$(pyenv init -)"; fi
source/etc/profile.d/pyenv.sh
pyenv install 2.7.1 #安装很慢，多等一会，如果想安装3.x以上则更改3.5.1即可
pip3 install ipython #可以补全，可以多彩显示
