【Python】Linux安装新版本Python步骤

一. 安装依赖库

yum -y install python-devel openssl openssl-devel gcc sqlite sqlite-devel mysql-devel libxml2-devel libxslt-devel tkinter tk-devel

#下载Python

1. mkdir /tmp/python
2. cd /tmp/python
3. wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz

二. 解压Python

1. cd /tmp/python
2. tar -zxf Python-2.7.13.tgz

三. 编译安装

1. cd Python-2.7.13
2. ./configure
3. make
4. make install

四. 给新版本Python创建软连接

1. ln -s /usr/local/python2.7/lib/libpython2.7.so /usr/lib
2. ln -s /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib
3. ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python
4. ln -s /usr/local/python2.7/lib/libpython2.7.so /usr/lib64
5. ln -s /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib64

五. 安装pip

1. wget https://bootstrap.pypa.io/get-pip.py
2. python get-pip.py

六. 安装easy-install

1. wget https://bootstrap.pypa.io/ez_setup.py
2. python ez_setup.py

七. Python中文编码

Python默认情况使用ASCII编码来读取源码，所以中文就会出现乱码。
Python解决中文编码只需要在文件开头输入以下内容

#!/usr/bin/python
# -*- coding: utf-8 -*-
