Install the Python Fabric runtime environment in CentOS 6.3

Fabric is always not installed successfully when you install fabric in CentOS6.3, and an error is always thrown when you execute the fab command.
Traceback (most recent call last ):

Solution

Install Python2.7 to replace the default Python2.6, and then install the fabric package.

Centos6.3 the default Python version is 2.6.

1. Download The Python2.7 installation package
Download the 2.7 source code package on the Python official website.
Wget https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tar.xz

2. decompress, compile, and install
Xz-d Python-2.7.8.tar.xz
Tar xvf Python-2.7.8.tar
Cd Python-2.7.8
./Configure -- prefix =/usr/local/python2.7
Make
Make install

3. Create a soft connection to overwrite the default python
Ln-fs/usr/local/python2.7/bin/python2.7/usr/bin/python

The yum of the system depends on python2.6. At this time, the default python version of the system is 2. 7. *. To ensure that yum runs properly, make sure to modify/usr/bin/yum.
Vi/usr/bin/yum

Set the #! Of the first line #! /Usr/bin/python #! /Usr/bin/python2.6

4. Install pip package management tool

Pip is a tool for installing and managing python packages.
Wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py
Python get-pip.py
Ln-fs/usr/local/python2.7/bin/pip/usr/bin/pip

5. Install fabric
Pip install fabric
Ln-fs/usr/local/python2.7/bin/fab/usr/bin/fab

Here fabric has been installed and can run properly. After a long time, it has finally been completed .~~~ Installing fabric in Ubuntu saves a lot of trouble.
