Linux7.1 離線安裝paramiko
環境：redhat7.1 系統自帶python 2.7.5 無外網
1.安裝gcc 和 python-devel
yum -y install gcc python-devel
2.安裝pip與setuptools
pip可以不限制版本，但setuptools最好用18.5
倆包解壓縮後進入目錄，執行
3.安裝pycrypto

安裝方式依然是解壓縮，執行python setup.py install(後面不再敖述)
4.安裝six-1.4.1.tar.gz，cffi-1.11.5-cp27-cp27mu-manylinux1_x86_64.whl
下載地址
https://pypi.org/project/cffi/#files
whl格式安裝方式用pip,執行
5.安裝PyNaCl

6.安裝cryptography
先安裝 openssl-devel系統自帶的有，用yum就好
然後安裝依賴包 ipaddress-1.0.22 ;enum34 ;idna>=2.1 ;asn1crypto>=0.21.0 需要先行安裝，此處就是為何要安裝setuptools 18.5了，因為最新的40.5不識別.
