centos python升级及easy_install安装模块

centos6.5更新python2.7影响pip和easy_install

• 一般更新python的时候只知道会影响yum，但没注意会影响pip和easy_install，需要卸载安装

  
  

1. 安装依赖环境

   1. yum install zlib-devel zlibopenssl openssl-devel readline-devel(zlib安装setuptools的时候会用到，没有的会报“RuntimeError: Compression requires the (missing) zlib module”；openssl是pip会用到，没有会报ImportError: cannot import name HTTPSHandle，如果不提前安装会来回重新编译安装python，很浪费时间)

2. 安装python

   1. wget https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tar.xz

   2. tar -xvf Python-2.7.8.tar.xz

   3. cd Python-2.7.8 &&./configure && make && make install

   4. mv /usr/bin/python /usr/bin/python_old

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

3. 修改yum

   1. vim /usr/bin/yum（把第一行的语言环境改成python_old）

4. 安装pip

   1. wget https://pypi.python.org/packages/source/p/pip/pip-7.1.2.tar.gz#md5=3823d2343d9f3aaab21cf9c917710196

   2. tar xf pip-7.1.2.tar.gz &&cd pip-7.1.2 && python setup.py install

   3. pip install --upgrade pip

   4. pip -V

5. 安装easy_install

   1. wget https://pypi.python.org/packages/source/s/setuptools/setuptools-18.2.tar.gz#md5=52b4e48939ef311d7204f8fe940764f4

   2. tar fxz setuptools-18.2.tar.gz &&cd setuptools-18.2 &&python setup.py install

CentOS安装python的easy_install

直接安装easy_install不行，听说python-setuptools这个工具已经自带easy install这个了，所以直接下载setuptools就行了。

[root@localhost yum.repos.d]# yum -y install python-setuptools
结果：
Loaded plugins: fastestmirror, refresh-packagekit, security

Complete!

再用easy_install命令安装 simplejson：

[root@localhost yum.repos.d]# easy_install simplejson
Searching for simplejson

找不到文件，说明没有找到这个东西，安装失败。

easy_install cx_Oracle(python包)在Windows上

$sudo alien -i oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm

ORACLE_HOME=/usr/lib/oracle/<version>/client64/lib/
LD_LIBRARY_PATH=/usr/lib/oracle/<version>/client64/lib/

$sudo ln -s /usr/include/oracle/<version>/client $ORACLE_HOME/include  # for 32bits arch,OR
$sudo ln -s /usr/include/oracle/<version>/client64 $ORACLE_HOME/include  # for 64bits arch

/lib  
  /usr/lib/oracle/<version>/client/lib  ; for 32bits arch,OR
  /usr/lib/oracle/<version>/client64/lib  ; for 64bits arch

$sudo ldconfig
