    1. install python 2.7

    refer: http://www.cnblogs.com/minglog/archive/2011/04/20/2022479.html

    wget http://www.python.org/ftp/python/2.7.2/Python-2.7.2.tar.bz2

    ./configure

    make

    make install

    rm /usr/bin/python

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

    *******************

    发现yum不能用了，yum依赖python2.4, 处理如下：

    vim /usr/bin/yum

    将文件头部的

    #!/usr/bin/python

    改成

    #!/usr/bin/python2.4

    就可以继续使用yum了

    *******************

    2. install setuptools

    wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg#md5=fe1f997bc722265116870bc7919059ea

    sh setuptools-0.6c11-py2.7.egg

    3. install python modules

    .feedparser

    #easy_install feedparser 编码处理有些问题

    下载feedparser-5.0.1源码

    feedparser.py 3524行

    elif http_content_type.startswith('text/'):

            #true_encoding = http_encoding or 'us-ascii'

            true_encoding = http_encoding or xml_encoding or 'utf-8'

      python setup.py build

            python setup.py install

            .BeautifulSoup

    easy_install BeautifulSoup

            .chardet

    easy_install chardet

    .PIL

    yum install libjpeg-devel zlib-devel freetype-devel

    #easy_install PIL #has problems, not support jpeg, etc

    wget http://effbot.org/downloads/Imaging-1.1.7.tar.gz

    python setup.py build_ext -i

    python setup.py install

    .MySQLdb

    yum install mysql-devel

    http://ncu.dl.sourceforge.net/project/mysql-python/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz

    python setup.py build

    python setup.py install

    4. Tips

    easy_install安装后如何删除

    编辑 /usr/local/lib/python2.7/site-packages/easy-install.pth , 删除相应的行。删除相应的egg文件。

    python -u

    -u     : unbuffered binary stdout and stderr; also PYTHONUNBUFFERED=x
             see man page for details on internal buffering relating to '-u'
