This host can't access internet directly, but I built a tinyproxy server on 10.21.3.31:8888. So on this host I setup a HTTPS proxy:

# export https_proxy=http://10.21.3.31:8888
# export http_proxy=http://10.21.3.31:8888

Then pip can use this proxy to install fabric.

The following installation process is based on How to install Python 2.7 and Python 3.3 on CentOS 6

1. yum groupinstall development

2. yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

3. Download Python 2.7.6 source code tarball from http://python.org/ftp/python/2.7.6/Python-2.7.6.tar.xz

4. tar xf Python-2.7.6.tar.xz

5. cd Python-2.7.6

6. ./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"

7. make && make altinstall

8. Verify: which python2.7

9. Download setuptools-3.4.3.zip from https://pypi.python.org/pypi/setuptools

10. unzip setuptools-3.4.3.zip

11. cd setuptools-3.4.3

12. python2.7 setup.py install

13. Download pip-1.5.4.tar.gz from https://pypi.python.org/pypi/pip

14. tar zxvf pip-1.5.4.tar.gz

15. cd pip-1.5.4

16. python2.7 setup.py install

17. Verify: which pip2.7;

18. pip2.7 install fabric

If it doesn't work, download Fabric-1.8.3.tar.gz, paramiko-1.12.3.tar.gz and pycrypto-2.6.1.tar.gz on PYPI, the install them locally:

# pip2.7 install pycrypto-2.6.1.tar.gz
# pip2.7 install paramiko-1.12.3.tar.gz
# pip2.7 install Fabric-1.8.3.tar.gz

1. Verify: fab --version;

Bingo!
