1、安装python2.7.11

1.1、安装原则：
　　在不影响默认系统自带的python2.6.6的情况下安装python2.7.11

1.2、安装依赖包

shell>yum install -y gcc  zlib-devel openssl openssl-devel python-devel readline-devel
1.3、下载python2.7.11

shell>cd /usr/src
shell>wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz
1.4、安装
　　将python2.7安装到/usr/local目录下

shell>tar zxvf Python-2.7.11.tgz
shell>cd Python-2.7.11
shell>./configure  --prefix=/usr/local/python2.7
shell>make
shell>make install
1.5、安装后目录结构

[root@localhost python2.7]# pwd
/usr/local/python2.7
[root@localhost python2.7]# ll
total 16
drwxr-xr-x. 2 root root 4096 Feb 14 22:22 bin
drwxr-xr-x. 3 root root 4096 Feb 14 22:22 include
drwxr-xr-x. 4 root root 4096 Feb 14 22:22 lib
drwxr-xr-x. 3 root root 4096 Feb 14 22:22 share
2、安装setuptools

shell>cd /usr/src
shell>wget https://pypi.python.org/packages/source/s/setuptools/setuptools-20.1.1.tar.gz
https://pypi.python.org/packages/ff/d4/209f4939c49e31f5524fa0027bf1c8ec3107abaf7c61fdaad704a648c281/setuptools-21.0.0.tar.gz
shell>tar zxvf setuptools-20.1.1.tar.gz
shell>cd setuptools-20.1.1
shell>/usr/local/python2.7/bin/python2.7 setup.py install

3、安装pip

shell>cd /usr/src
shell>wget https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz
shell>tar zxvf pip-8.0.2.tar.gz
shell>cd pip-8.0.2
shell>/usr/local/python2.7/bin/python2.7 setup.py  install
4、安装python包

shell>cd /usr/local/python2.7/bin
shell>./pip2.7 install yaml ua_parser user_agents
5、测试包安装是否成功

[root@localhost bin]# pwd
/usr/local/python2.7/bin
[root@localhost bin]# /usr/local/python2.7/bin/python
Python 2.7.11 (default, Feb 14 2016, 22:19:05)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import yaml
>>> import ua_parser
>>> import user_agents
>>>
6、创建软连接
　　将python2.7\pip2.7放到环境变量目录下。例如：/usr/bin/目录，这样在调用的饿时候就不用到python的安装目录下去执行，直接调用就可以。

shell>ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python2.7
shell>ln -s /usr/local/python2.7/bin/pip2.7 /usr/bin/pip2.7
