在CentOS 5.3源码安装Python 2.7及模块

      最近需要在服务器上建立一个Python环境,第一次做,故做些记录.

      服务器采用的系统为CentOS release 5.3 (Final),采用源码安装Python 2.7.3.

      1.Python

      软件包版本: Python-2.7.3

      下载地址: http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2

      安装过程:

      a.将软件包至于合适的目录解包.

      此处在/usr/local/src中操作.执行命令:

tar -xjf Python-2.7.3.tar.bz2

 

      b.配置,编译与安装

      安装过程中没有做特别的要求,所以简单执行如下的命令:

./configure
make
make install

       至此,完成Python安装.

      2.安装setuptools和easy_install

      a.获取脚本ez_setup.py.此脚本将帮助获取setuptools的最新版本,并自动安装easy_install.

      执行:

curl http://peak.telecommunity.com/dist/ez_setup.py > ez_setup.py

 

      b.运行脚本ez_setup.py.需要注意的是,运行此脚本时要确定一起工作的Python版本,必要时直接指明是哪个版本.

      执行:

python ez_setup.py

      得到类似下面的输出:

Downloading http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg
Processing setuptools-0.6c11-py2.7.egg
Copying setuptools-0.6c11-py2.7.egg to /usr/local/lib/python2.7/site-packages
Adding setuptools 0.6c11 to easy-install.pth file
Installing easy_install script to /usr/local/bin
Installing easy_install-2.7 script to /usr/local/bin

Installed /usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg
Processing dependencies for setuptools==0.6c11
Finished processing dependencies for setuptools==0.6c11

 

      此时,查看下目录/usr/local/bin,会见到下面两个文件:

       /usr/local/bin/easy_install

       /usr/local/bin/easy_install-2.7

 

      3.安装几个模块

      下面安装几个需要的模块,包括: jianfan, mysql-python.

      安装jianfan,执行:

easy_install jianfan

       得到类似输出:

      安装mysql-python,执行:

easy_install mysql-python

       得到类似输出:

      在安装mysql-python,可能会遇到系统缺少和MySQL相关的必要包;此时可以使用yum进行安装.

         执行:

yum install mysql-devel

 

      验证看看刚才的两个模块是否已安装成功,进入python,使用import试试.比如在python交互式shell中,执行:

      import MySQLdb

      如果没有报错,则说明安装已成功.
