1.先下载：pycrypto-2.6.tar.gz paramiko-1.7.5.zip gmp-5.1.2.tar.bz2

2.安装pycrypto

wget http://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.6.tar.gz
tar -xf pycrypto-2.6.tar.gz
cd pycrypto-2.6/
python setup.py build && python setup.py install

3.安装 paramiko

wget https://pypi.python.org/packages/2b/27/b64860e7b208ff1dd36fe208d07bca1f9637a11fe733e2f2ceea587c3f75/paramiko-1.7.5.zip
unzip paramiko-1.7.5.zip
cd paramiko-1.7.5
python setup.py build && python setup.py install
测试：
python>> import paramiko***注意 python2.7，Centos7以上不会出现以下错误，已经测试过。***报错
/usr/lib64/python2.4/site-packages/Crypto/Util/number.py:57: PowmInsecureWarning: Not using mpz_powm_sec.  You should rebuild using libgmp >= 5 to avoid timing attack vulnerability._warn("Not using mpz_powm_sec.  You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.", PowmInsecureWarning)
/usr/lib64/python2.4/site-packages/Crypto/Util/randpool.py:40: RandomPool_DeprecationWarning: This application uses RandomPool, which is BROKEN in older releases.  See http://www.pycrypto.org/randpool-brokenRandomPool_DeprecationWarning)打开该文件，用#注释掉这两行39和40行代码：vim /usr/lib64/python2.4/site-packages/Crypto/Util/randpool.py

修改后再次运行报错：

>>> import paramiko
/usr/lib64/python2.4/site-packages/Crypto/Util/number.py:57: PowmInsecureWarning: Not using mpz_powm_sec.  You should rebuild using libgmp >= 5 to avoid timing attack vulnerability._warn("Not using mpz_powm_sec.  You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.", PowmInsecureWarning)

这个报错是gpm版本太低了，
rpm -qa|grep gmp
gmp-devel-4.1.4-10.el5
gmp-4.1.4-10.el5
gmp-devel-4.1.4-10.el5
gmp-4.1.4-10.el5

删除
yum remove gmp*

再次安装下载gmp5

wget http://ftp.gnu.org/gnu/gmp/gmp-5.1.2.tar.bz2tar jxf gmp-5.1.2.tar.bz2
cd gmp-5.1.2./configure && make && make install
echo "/usr/local/lib" >> /etc/ld.so.confldconfig

然后再次运行：

[root@tcas302 awpy]# python
Python 2.4.3 (#1, Oct 23 2012, 22:02:41)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import paramiko

会报错

Traceback (most recent call last):File "test.py", line 3, in ?import paramiko
ImportError: No module named paramiko

紧接着重新安装下paramiko即可

cd paramiko-1.7.5
python setup.py build && python setup.py install

再次执行就好了

[root@tcas302 awpy]# python
Python 2.4.3 (#1, Oct 23 2012, 22:02:41)

>>> import paramiko
