Detailed installation steps:
First, update python
The default installed Python in CentOS is version 2.4, because the new rails need to provide nodejs support, need to update Python, update the article can be directly to the link Http://www.tomtalk.net/wiki/Python
Copy Code code as follows:
Yum install-y bzip2* #nodejs 0.8.5 required, install this module before you install Python.
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz
Tar zvxf python-2.7.3.tgz
CD Python-2.7.3
./configure
Make && make install
/usr/local/bin/python2.7-v #查看Python版本
Establish a soft connection so that the system's default Python points to python2.7
Normally, even if the python2.7 installation is successful, the system's default pointing Python is still 2.4.3, considering that Yum is based on python2.4.3 to work properly and is not easy to uninstall.
Copy Code code as follows:
Mv/usr/bin/python/usr/bin/python.bak
Ln-s//usr/local/bin/python2.6/usr/bin/python
Python-v #检验python指向是否成功
Resolving system Python Soft links point to python2.6 version, yum not working properly
Copy Code code as follows:
$vi/usr/bin/yum
Change the #/usr/bin/python of the text edit to #/usr/bin/python2.4 and save the changes.
second, the installation of dependent packages
#yum install gcc gcc-c++ openssl* readline* ncurses* zlib* libxml* libjpeg* libpng* libxslt* libtool*
