安装Python3及ipython的完整环境，确实需要仔细配置，稍不留神就会遇到各种问题。以下是完整的安装流程记录，供后续查阅。

首先，安装Python3.5环境为了确保依赖软件的完整性，首先需要安装Development tools组件：

yum groupinstall "Development tools"yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

接下来下载并编译Python3.5源码：

wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0.tgztar xf Python-3.5.0.tgzcd Python-3.5.0./configure --prefix=/ --enable-sharedmakemake installln -s /application/python/bin/python3 /usr/bin/python3

在编译完成后，运行以下命令确保库文件可见：

echo /usr/local/lib > /etc/ld.so.conf.d/local.confldconfig

验证Python环境：

python3 --version

运行完成后清理旧环境：

yum groupremove "Development tools" --remove-leaveasyum remove zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel --remove-leaves

建议设置Python别名：

alias py=python3

接下来安装ipython3安装前需先安装setuptools：

tar xf setuptools-36.5.0.zipcd setuptools-36.5.0/application/python/bin/python3 setup.py install

安装pip：

tar xf pip-9.0.1.tar.gzcd pip-9.0.1/application/python/bin/python3 setup.py install

安装python-setuptools和python-setuptools-devel：

yum install python-setuptools python-setuptools-devel

最后安装ipython：

tar xf ipython-6.0.0.tar.gzcd ipython-6.0.0/application/python/bin/python3 setup.py install

建议将ipython3添加为系统默认命令：

ln -s /application/python/bin/python3 /usr/bin/python3ln -s /application/python/bin/ipython3 /usr/bin/ipython3ln -s /application/python/bin/ipython /usr/bin/ipython
