centos5.x升级至python2.7、mysql-python

centos5.3的python版本真让人泪奔，什么时代了还2.4的。自己动手丰衣足食。

1.从官网下载

2.7版本

# wget /ftp/python/2.7.1/Python-2.7.1.tar.bz2

2.安装

# tar -jxvf Python-2.7.1.tar.bz2

# cd Python-2.7.1

# ./configure （如不指定 --prefix，默认安装在/usr/local/lib/python2.7）

# make && make install

3.升级默认版本

# mv python /usr/bin/python24

# ln -s /usr/local/bin/python2.7 /usr/bin/python

4.安装m ysql-python

(安装方法不了解可以参看包内的README)

# python setup.py build

Traceback (most recent call last):

File "setup.py", line 5, in

from setuptools import setup, Extension

ImportError: No module named setuptools

什么情况？貌似setuptools没有

5.去官网下载setuptools

官网下载地址

# bash setuptools-0.6c11-py2.7.egg

Traceback (most recent call last):

File "", line 1, in

zipimport.ZipImportError: can't decompress data; zlib not available

又是什么情况？缺少zlib?(关于安装python所需的软件环境可参看README)

这一步我花了很长时间解决它，过程实在是很让人不爽。从上面这个错误提示似乎是zlib没有，最先想到的是使用yum安装zlib*。

# rpm -qa | grep zlib

zlib-1.2.3-3

zlib-devel-1.2.3-3

重新编译python以后，依旧提示这个错误"zipimport.ZipImportError: can't decompress data; zlib not available"，到最后都有点抓狂了。快要发飙的时候浏览了zlib的官站，它的最新版本是zlib-1.2.5。我决定用 tar包安装最新版本试试。

安装过程非常简单，仍是老三步：

# cd zlib-1.2.5

# ./configure

# make && make install

在解决该问题的过程中，我发现了python安装方法中最简易的一种“easy_install”，将使用它来安装m ysql-python

# wget /dist/ez_setup.py

# python ez_setup.py

Downloading /packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg Processing setuptools-0.6c11-py2.7.egg

在上一步步骤中，它自行安装了setuptools-0.6c11-py2.7.egg，这样就可以使用 easy_install 了。

4.安装MySQL-python

# easy_install MySQL-python
