云服务器的python2.7安装

2、 安装python2.7

机器自带python2.4.3版本；但是，很多新功能都是基于2.7来的；比如多进程、装饰器等；

于是，需要自己准备python环境了；

python环境准备：

wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz tar zxf Python-2.7.3.tgz cd Python-2.7.3 ./configure --prefix=/usr/local/python27 make make install ln -sf /usr/local/python27/bin/python2.7 /usr/local/bin/python2.7

ln -sf /usr/local/python27/bin/python2.7 /usr/local/bin/python

sudo vi .bash_profile

PATH=/usr/local/bin:$PATH

这样，python就可以直接使用了；

[admin@iZ28lzm2ehvZ Python-2.7.3]$ python --version

Python 2.7.3

[admin@iZ28lzm2ehvZ Python-2.7.3]$

        然后安装setuptools，即easy_install。

wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefe74e tar zxf setuptools-0.6c11.tar.gz cd setuptools-0.6c11 python2.7 setup.py install 

  File "/usr/local/python27/lib/python2.7/distutils/dist.py", line 972, in run_command

    cmd_obj.run()

  File "/home/admin/software/setuptools-0.6c11/setuptools/command/bdist_egg.py", line 236, in run

    dry_run=self.dry_run, mode=self.gen_header())

  File "/home/admin/software/setuptools-0.6c11/setuptools/command/bdist_egg.py", line 527, in make_zipfile

    z = zipfile.ZipFile(zip_filename, mode, compression=compression)

  File "/usr/local/python27/lib/python2.7/zipfile.py", line 681, in __init__

    "Compression requires the (missing) zlib module"

RuntimeError: Compression requires the (missing) zlib module

zlib官方网站：http://www.zlib.net上下载源码来安装zlib软件包。目前最新版本zlib是zlib1.2.3，安装开始；$wget http://www.zlib.net/zlib-1.2.3.tar.gz$tar -xvzf zlib-1.2.3.tar.gz$cd zlib-1.2.3.tar.gz$./configure$make$sudo make install

安装完毕后，重新来安装一次python2.7；

Python build finished, but the necessary bits to build these modules were not found:

_bsddb             _curses            _curses_panel

           _ssl               _tkinter

bsddb185           bz2                dbm

dl                 gdbm               imageop

readline           sunaudiodev

To find the necessary bits, look in setup.py in detect_modules() for the module‘s name.

ln -sf /usr/local/python27/bin/easy_install-2.7 /usr/local/bin/easy_install-2.7

ln -sf /usr/local/python27/bin/easy_install-2.7 /usr/local/bin/easy_install

easy_install

Traceback (most recent call last):

  File "/usr/local/bin/easy_install", line 5, in ?

    from pkg_resources import load_entry_point

ImportError: No module named pkg_resources

         重新python2.7安装easy_install;重新执行，找不到包：

 196  wget -c http://www.openssl.org/source/openssl-1.0.1e.tar.gz

  197  tar xzvf openssl-1.0.1e.tar.gz

  198  cd openssl-1.0.1e

  199  ./config --prefix=/usr/local/openssl

  200  make

好了，现在如果要用自带的Python，则直接运行对应的py文件即可，如果要用安装的Python2.7，则使用“python2.7 xxx.py”即可。

使用easy_install也是，自带的直接运行“easy_install xxx”，对应Python2.7的运行“easy_install2.7 xxx”。
