环境为centos6.7
python3为源码编译安装的，系统自带的python2 可以直接使用paramiko模块，但是在py3的环境下加载出错，所有需要安装新的paramiko 模块；
上了paramiko官网后，发现要求用pip安装，所以centos 先安装pip；
开始情况：
[root@localhost ~]# python3.
Python 3.4. (default, Mar , ::)
[GCC 4.4. (Red Hat 4.4.-)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> import paramiko
Traceback (most recent call last):
File "<stdin>", line , in <module>
ImportError: No module named 'paramiko'
>>>
安装PIP
wget --no-check-certificate https://github.com/pypa/pip/archive/1.5.5.tar.gz
tar -zxvf 1.5..tar.gz
cd pip-1.5./
python3 setup.py install
pip3 install requests
pip install paramiko
之后结果：
python3
[root@localhost ~]# python3.
