optimization

Key to write a script to install the python2.7

Because Centos 6.x system default is python2.6, if need 2.7 server environment, then each had to manually upgrade, the workload is relatively large, scripting improve efficiency. (Default python Centos 7.x version is 2.7.5 version)

Create a directory for storing python script

[root@server2 software]# mkdir /script/python/ [root@server2 software]# cd /script/python/ 

As foreign python website to download the installation package python slow down can be downloaded in advance, and install_py27.sh together, directly extract a local file to install it in the script, I have uploaded to the network disk
click on my download

He began writing scripts install_py27.sh

# __author__ = 'junxi'

# This script is used by fast installed python2.7 ......
# write by 2017/04/11
