On Linux SUSE or RedHat, how to download Python 2.7

Question

Can someone provide the steps needed to install python version 2.7 on SUSE and RedHat? This version that is there is 2.4, and I need to have it at least 2.6 for my script to work. Therefore, after installation, I can enter Python in xTerm and get the Python 2.7 command line interface.

Answer 1

Instructions for downloading the source code and installing:

https://www.python.org/download/

NOTE. You should check the latest version of python 2.7.x, as it is updated frequently. Currently (October 2017) the latest version is version 2.7.14, although this comment will become old and new versions are likely to be released every 6 months or so.

wget https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tgz # Download tar xvfz Python-2.7.14.tgz # unzip cd Python-2.7.14 # go into directory ./configure make # build su # or 'sudo su' if there is no root user make altinstall 

(EDIT: make install -> make altinstall on Ignacio's comment).

RHEL 6.2 using (had Python 2.6, I need Python 2.7.3 ) So:

Answer 3

The accepted answer by dr jimbob (using make altinstall ) delivered me most of the way, with python2.7 in /usr/local/bin , but I also needed to install some third-party modules. The best part is that easy_install gets its installation locations from the Python version that you are running, but I found that I still need to install easy_install for Python 2.7, otherwise I would get ImportError: No module named pkg_resources . So I did this:

 wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg sudo -i export PATH=$PATH:/usr/local/bin sh setuptools-0.6c11-py2.7.egg exit 

Now I have easy_install and easy_install-2.7 in / usr / local / bin, and the first one overrides my version of 2.6 easy_install, so I deleted it:

 sudo rm /usr/local/bin/easy_install 

Now I can install the libraries for Python version 2.7 as follows:

 sudo /usr/local/bin/easy_install-2.7 numpy

To install Python 2.7.2 use this script - https://github.com/bngsudheer/bangadmin/blob/master/linux/centos/6/x86_64/build-python-27.sh

It also ensures that you get sqlite and readline support.

Answer 5

You must leave Python 2.4 installed on RHEL / Centos; otherwise the tools begin to break. However, you can do a double installation; I talk about it here:

http://thebuild.com/blog/2009/10/17/wordpress-to-djangopostgresql-part-3-installing-apache-python-2-6-psycopg2-and-mod_wsgi/

The post is about 2.6, but equally applies to 2.7.

Answer 6

Run the following commands to make yum work as well as python2.7

 yum groupinstall -y development yum groupinstall -y 'development tools' yum install -y zlib-dev openssl-devel wget sqlite-devel bzip2-devel yum -y install gcc gcc-c++ numpy python-devel scipy git boost* yum install -y *lapack* yum install -y gcc gcc-c++ make bison flex autoconf libtool memcached libevent libevent-devel uuidd libuuid-devel boost boost-devel libcurl-dev libcurl curl gperf mysql-devel cd mkdir srk cd srk wget http://www.python.org/ftp/python/2.7.6/Python-2.7.6.tar.xz yum install xz-libs xz -d Python-2.7.6.tar.xz tar -xvf Python-2.7.6.tar cd Python-2.7.6 ./configure --prefix=/usr/local make make altinstall echo "export PATH="/usr/local/bin:$PATH"" >> /etc/profile source /etc/profile mv /usr/bin/python /usr/bin/python.bak update-alternatives --install /usr/bin/python python /usr/bin/python2.6 1 update-alternatives --install /usr/bin/python python /usr/local/bin/python2.7 2 update-alternatives --config python sed -i "s/python/python2.6/g" /usr/bin/yum 

Answer 7

The great thing about Linux, you can still download the source , and most systems have all the tools to compile the version yourself.

To get the python cli from xterm simply by typing python , the python bin directory must be in your system path variable ( Red Hat example, Suse example )

Answer 8

If you can live with 2.6, EPEL has it for RHEL 5 in the python26 package, although you will need to use python2.6 to invoke it, since python for 2.4 will still be required for the system to work.

Answer 9

If you need a tool for input and configuration, please install openssl and opessl-devl before doing python2.7

  yum install openssl-devel 

Then follow the https://stackoverflow.com/a/464690/

Then https://pypi.python.org/pypi/setuptools

 wget https://bootstrap.pypa.io/ez_setup.py python2.7 ez_setup.py 

Then to install pip

 wget https://bootstrap.pypa.io/get-pip.py python2.7 get-pip.py 

Then to install other pip2.7 packages install package_name

If you want to install Python 2.7 on Oracle Linux, you can proceed as follows:

Include the software build in /etc/yum.repos.d/public-yum-ol6.repo.

 vim /etc/yum.repos.d/public-yum-ol6.repo [public_ol6_software_collections] name=Software Collection Library release 1.2 packages for Oracle Linux 6 (x86_64) baseurl=[http://yum.oracle.com/repo/OracleLinux/OL6/SoftwareCollections12/x86_64/][1] gpgkey=file:[///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle][2] gpgcheck=1 enabled=1 <==============change from 0 to 1 

After making this change to the yum repository, you can simply run the yum command to install Python:

 yum install gcc libffi libffi-devel python27 python27-python-devel openssl-devel python27-MySQL-python 

modify bash_profile with the following variables:

 vim ~/.bash_profile PATH=$PATH:$HOME/bin:/opt/rh/python27/root/usr/bin export PATH LD_LIBRARY_PATH=/opt/rh/python27/root/usr/lib64 export LD_LIBRARY_PATH PKG_CONFIG_PATH=/opt/rh/python27/root/usr/lib64/pkgconfig export PKG_CONFIG_PATH 

Now you can use python2.7 and pip to install Python modules:

 /opt/rh/python27/root/usr/bin/pip install pynacl /opt/rh/python27/root/usr/bin/python2.7 --version
