CentOS 6.2 and 6.3 ships with Python 2.6.6. You can manually install Python 2.7 and Python 3.3 but you must be careful to leave the system version alone. Several critical utilities, for example yum, depend on Python 2.6.6 and if you replace it bad things will happen.
Below are the steps necessary to install Python 2.7.3 and Python 3.3.0 without touching the system version of Python. The procedure is exactly the same for both versions except for the filenames. People have reported that this also works for CentOS 5.8 but I haven’t tested that. Execute all the commands below as root either by logging in as root or by using sudo.
Install development tools
In order to compile Python you must first install the development tools and a few extra libs. The extra libs are not strictly needed to compile Python but without them your new Python interpreter will be quite useless.
# yum groupinstall "Development tools" # yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel
Download and install Python
It is critical that you use make altinstall below. If you use make install you will end up with two different versions of Python in the filesystem both named python. This can lead to problems that are very hard to diagnose.
Download and install Python 2.7.3
# wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2 # tar xf Python-2.7.3.tar.bz2 # cd Python-2.7.3 # ./configure --prefix=/usr/local # make && make altinstall Tiếp tục đọc "How to install Python 2.7 and 3.3 on CentOS 6"
