CentOS python2.6 Upgrade to 2.7

View Python version

#python  -V    2.6.  6  

1. Download Python-2.7.3

#wget http://python.org/ftp/python/2.7.3/python-2.7.3.tar.bz2  

2. Unzip

#tar-JXVF python-2.7. 3 . tar.bz2  #cd Python-2.7. 3  

3. Installation

#./Configure  #make all             #make install  #make clean  #make distclean  

4. View version Information

#/usr/local/bin/python2. 7

5. Establish a soft connection so that the system default Python points to python2.7

#mv/usr/bin/python/usr/bin/python2. 6.6    -s/usr/local/bin/python2. 7

6. Re-test Python version 7. Change the Yum profile header

After the system Python soft links point to the Python2.7 version, because Yum is not compatible with Python 2.7, Yum does not work properly and we need to specify the Python version of Yum

#vi/usr/bin/Yum changes the  file header's #!/usr/bin/python to #!/usr/bin/python2.  6.6

8. Input method is gone, configure the IBUs

Use VI to open the following two files, find the Exec Python line, the exec python changed to exec python2.6 save, exit. The IBUs is back to normal after a reboot!

#vi/usr/bin/ibus-setup  #vi/USR/LIBEXEC/IBUS-UI-GTK
