在Windows和Linux上安装paramiko模块

一、paramiko模块有什么用？paramiko是用python语言写的一个模块，遵循SSH2协议，支持以加密和认证的方式，进行远程服务器的连接。由于使用的是python这样的能够跨平台运行的语言，所以所有python支持的平台，如Linux, Solaris, BSD, MacOS X, Windows等，paramiko都可以支持，因此，如果需要使用SSH从一个平台连接到另外一个平台，进行一系列的操作时，比如：批量执行命令，批量上传文件等操作，paramiko是最佳工具之一。
目前新的版本,官网在此：

旧版本在此：
http://www.lag.net/paramiko/legacy.html要安装新版本paramiko模块需要做以下准备：1.Python2.5+ 版本（Linux, Unix, Windows都可以）,这里就直接安装Python2.7
下载地址：http://www.python.org2.PyCrypto 2.1+ 模块（PyCrypto是使用Python编写的加密工具包）
下载地址：https://www.dlitz.net/software/pycrypto/3.easy_install 工具（是Python安装模块的一个工具，像yum，可以自动解决依赖）
下载地址： http://peak.telecommunity.com/dist/ez_setup.py如果大家感觉安装paramiko还是略有麻烦的话，当使用到paramiko提供的方便时便会觉得这是十分值得的。相关阅读：RHEL6下安装Python相关的paramiko http://www.linuxidc.com/Linux/2012-07/65353.htmPython模块paramiko的上传下载和远程执行命令方法 http://www.linuxidc.com/Linux/2012-11/74078.htmpython paramiko模块中设置执行命令超时值 http://www.linuxidc.com/Linux/2013-05/85185.htm二、Linux上安装paramiko（以CentOS 5.8 32位为例）1.查看Python的版本，是否满足要求[root@server1 ~]# python -V
Python 2.4.3
[root@server1 ~]#Windows上亦是此命令，注意是大写V
是2.4.3版本，需要升级2.下载安装python2.7源码安装Python2.7
如果没有gcc没有安装，请先安装好gcc
root@server2 ~]# wget http://www.python.org/ftp/python/2.7.5/Python-2.7.5.tar.bz2
[root@server2 ~]# tar jxf Python-2.7.5.tar.bz2
[root@server2 ~]# cd Python-2.7.5
[root@server2 Python-2.7.5]# ./configure --prefix=/usr/local/python2.7
[root@server2 Python-2.7.5]# make && make install
[root@server2 Python-2.7.5]# echo "PATH=/usr/local/python2.7/bin:$PATH" >> /etc/profile
[root@server2 Python-2.7.5]# source /etc/profile
[root@server2 Python-2.7.5]# python -V
Python 2.7.5
[root@server2 Python-2.7.5]# python
Python 2.7.5 （default, Aug 16 2013, 07:56:41）
[GCC 4.1.2 20080704 （Red Hat 4.1.2-52）] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>至此Python2.7 安装成功3.安装easy_install 工具下载该脚本
[root@server2 ~]# wget http://peak.telecommunity.com/dist/ez_setup.py
[root@server2 ~]# python ez_setup.py只需要执行以上命令，即可安装好easy_install 工具4.安装paramiko模块使用以下命令，即可安装好paramiko模块
1 [root@server2 ~]# easy_install paramiko进入Python导入paramiko一下试试
[root@server2 ~]# python
Python 2.7.5 （default, Aug 16 2013, 07:56:41）
[GCC 4.1.2 20080704 （Red Hat 4.1.2-52）] on linux2

>>> import paramiko
/usr/local/python2.7/lib/python2.7/site-packages/pycrypto-2.6-py2.7-linux-i686.egg/Crypto/Util/number.py:57: PowmInsecureWarning: Not using mpz_powm_sec. You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.
>>>导入模块时，如果遇到以上问题,可能是由于gmp版本比较低造成的，gmp是啥，看官网的解释：
GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers.
看样子是跟精度有关系
可以用以下方法解决：
先卸载低版本
root@server2 ~]# rpm -qa | grep gmp
gmp-devel-4.1.4-10.el5
gmp-4.1.4-10.el5
[root@server2 ~]# rpm -e gmp-devel-4.1.4-10.el5.i386
[root@server2 ~]# rpm -e gcc-gfortran-4.1.2-52.el5.i386
[root@server2 ~]# rpm -e gmp-4.1.4-10.el5
[root@server2 ~]# ldconfig
[root@server2 ~]#然后安装高版本的gmp[root@server2 ~]# wget http://ftp.gnu.org/gnu/gmp/gmp-5.1.2.tar.bz2
[root@server2 ~]# tar jxf gmp-5.1.2.tar.bz2
[root@server2 ~]# cd gmp-5.1.2
[root@server2 gmp-5.1.2]# ./configure && make && make install
[root@server2 gmp-5.1.2]# echo "/usr/local/lib" >> /etc/ld.so.conf
[root@server2 gmp-5.1.2]# ldconfig再次尝试导入paramiko模块：[root@server2 gmp-5.1.2]# python
