目前大部分用户使用的CentOS6.5上默认的Python还是2.6版本。升级到Python2.7碰到很多问题。本文将介绍如何安装Python2.7。

1. 安装必要的准备包

        安装过程将用到gcc,方便起见,安装“Development Tools”

yum groupinstall "Development tools"

         另外,Python安装中需要的一些依赖包

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel

2. 下载安装Python2.7

        目前Python2.7的最新版本是2.7.11。可以在下面的网站查询:

        https://www.python.org/ftp/python/

        2.7.11的下载链接是:

        https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz

wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz
tar vxf Python-2.7.11.tgz
cd Python-2.7.11.tgz
./configure --prefix=/usr/local
make && make install

  安装完成后,通过运行python,可以看到版本

>>> import sys
>>> sys.version
2.7.11 (default, May  6 2016, 01:38:00) \n[GCC 4.4.7 20120313 (Red Hat 4.4.7-16)]

3.安装pip

  pip是python的安装工具,很多python的常用工具,都可以通过pip进行安装。

  要安装pip,首先要安装setuptools。下面的链接可以得到相关信息,最新版本是21.0.0:

  https://pypi.python.org/pypi/setuptools

  下载链接:

  https://pypi.python.org/packages/ff/d4/209f4939c49e31f5524fa0027bf1c8ec3107abaf7c61fdaad704a648c281/setuptools-21.0.0.tar.gz#md5=81964fdb89534118707742e6d1a1ddb4

  同样的,进行安装:

tar vxf setuptools-21.0.0.tar.gz 
cd setuptools-21.0.0
python setup.py  install

  安装完成后,下载pip。其信息在如下网站:

  https://pypi.python.org/pypi/pip

  最新版是8.1.1,下载链接:

  https://pypi.python.org/packages/41/27/9a8d24e1b55bd8c85e4d022da2922cb206f183e2d18fee4e320c9547e751/pip-8.1.1.tar.gz#md5=6b86f11841e89c8241d689956ba99ed7

  同样的,进行安装

histfile = os.path.join(os.environ[HOME], .pythonhistory)
try:
   readline.read_history_file(histfile)
except IOError:
   pass
atexit.register(readline.write_history_file, histfile)
del os, histfile, readline, rlcompleter
