One of the Python starter series: CENTOS6 under python2.7 installation

1) Compile and install python2.7

[[email protected] ~]# python -vpython 2.6.6 View Python version information (previous yum was installed by yum) [[Email  protected] src]# wget https://www.python.org/ftp/python/2.7.9/python-2.7.9.tar.xz[[email  protected] src]# file Python-2.7.9.tar.xz Python-2.7.9.tar.xz: xz  Compressed data[[email protected] src]# xz -d python-2.7.9.tar.xz [[email  protected] src]# lsdebug  kernels  python-2.7.9.tar[[email protected]  src]# tar -xf Python-2.7.9.tar [[email protected] src]# cd  python-2.7.9[[email protected] python-2.7.9]# ./configure [[email protected]  python-2.7.9]# make && make install[[email protected] python-2.7.9]#  echo $?0[[email protected] python-2.7.9]# /usr/local/bin/python2.7 -vpython  2.7.9[[email protected] pYTHON-2.7.9]# MV /USR/BIN/PYTHON /USR/BIN/PYTHON2.6MV: Do you want to overwrite "/usr/bin/python2.6"?  yes[[email protected] python-2.7.9]# ln -s /usr/local/bin/python2.7 /usr/ bin/python[[email protected] python-2.7.9]# python -vpython 2.7.9

2) Adjust the configuration of Yum

Because Yum uses the information that calls Python, avoids reinstalling Python, yum error, edit yum file: [[email protected] python-2.7.9]# sed - i  ' [email protected]#!/usr/bin/[email protected]#!/usr/bin/[email protected] '  /usr/ bin/yum[[email protected] python-2.7.9]# cat /usr/bin/yum |head#!/usr/bin/ python2.6import systry:    import yumexcept importerror:     print >> sys.stderr,  "" "There was a problem importing one  of the python modulesrequired to run yum. the error leading  to this problem was:   %s[[email protected] Python-2.7.9]#  pythonpython 2.7.9  (default, nov 16 2016, 19:53:47)  [GCC 4.4.7  20120313  (red hat 4.4.7-16)] on linux2type  "Help",  "copyright",  " Credits " or " License " for more information.>>> print  "Hello,world" Hello,world to this, python2.7 's basic installation has also been completed.
