Python 3.8.1 Linux Install Without Root

For instance, if you wanted to install neofetch, here is how you might want to do this:

david@hplinux:~$ mkdir .root && .root #Create a pseudo root directory in your homedavid@hplinux:~/.root$ apt-get download neofetch #Download the neofetch package into the current directorydavid@hplinux:~/.root$ ls | grep neofetch #Show the full name of the downloaded packagedavid@hplinux:~/.root$ dpkg --extract $(ls | grep neofetch) . #Extract the package into the current directorydavid@hplinux:~/.root$ find . -name - f -executable #Find the location where the binary has been installeddavid@hplinux:~/.root$ >> ~/.bashrc
david@hplinux:~/.root$ ~/.bashrc #Source your bachrs to update the path inside the current terminaldavid@hplinux:~/.root$ neofetch #Actually run the commanddavid@hplinux:~/.root$ neofetch #Check that the command being run is actually from your pseudo root directory

I did a yum update on my Oracle Enterprise Linux 7.7 install before I started to get everything on the latest version. As root I used yum to install the Linux packages I needed to install Python 3.8.1 from source:

[bobby@pythonvm ~]$ curl -k -O https://www.python.org/ftp/python/3.8.1/Python-3.8.1.tgz % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed
100 22.8M 100 22.8M 0 0 7830k 0 0:00:02 0:00:02 --:--:-- 7828k

For some reason I had to do this twice. The first download failed. Next I gunzipped and untarred this archive under my home directory:

tar zxfv Python-3.8.1.tgz
Python-3.8.1/Objects/sliceobject.c
Python-3.8.1/Objects/listobject.c
Python-3.8.1/Objects/typeslots.inc
Python-3.8.1/Objects/weakrefobject.c
Python-3.8.1/Objects/unicodeobject.c
Python-3.8.1/Objects/complexobject.c
Python-3.8.1/Objects/picklebufobject.c
Python-3.8.1/Objects/odictobject.c
Python-3.8.1/Objects/genobject.c
[bobby@pythonvm ~]$

I created a directory called “python” under my home directory to use as the top-level directory for my Python install. This directory tree will hold the binaries and any Python packages that I install.

[bobby@pythonvm ~]$ mkdir python

After changing directory to where I untarred the source files I configured the Python make and install to use the directory I just created as a “prefix”:

[bobby@pythonvm ~]$ cd Python-3.8.1
[bobby@pythonvm Python-3.8.1]$ pwd
/home/bobby/Python-3.8.1
./configure --prefix=/home/bobby/python
config.status: creating Misc/python-embed.pc
config.status: creating Misc/python-config.sh
config.status: creating Modules/ld_so_aix
config.status: creating pyconfig.h
creating Modules/Setup.local
creating Makefile
If you want a release build with all stable optimizations active (PGO, etc),
please run ./configure --enable-optimizations

Then I did the make and make altinstall from the same directory:

So, now Python 3.8.1 is installed in /home/bobby/python but I want to put the bin directory in the path so I can run python or pip and by default have them be this version. The install created python and pip as python3.8 and pip3.8 but I created links to them so that I could access them without 3.8 at the end of their names:

[bobby@pythonvm Python-3.8.1]$ cd /home/bobby/python/bin
[bobby@pythonvm bin]$ ls -al
total 16704
drwxr-xr-x. 2 bobby bobby 4096 Feb 10 15:36 .

[bobby@pythonvm bin]$ ln -s python3.8 python
[bobby@pythonvm bin]$ ln -s pip3.8 pip

Then I added/home/bobby/python/bin to the front of the path to keep these new python and pip links ahead of the python links or binaries in the rest of the path.

[bobby@pythonvm bin]$ cd
[bobby@pythonvm ~]$ vi .bashrc
export ORACLE_HOME=/home/oracle/app/oracle/product/12.1.0/client_1
export PATH=$PATH:$ORACLE_HOME/bin

export PATH=/home/bobby/python/bin:$PATH

".bashrc" 17L, 451C written 

I logged out and in as bobby and tried python and pip to see that they were the correct version:

[bobby@pythonvm ~]$ python
Python 3.8.1 (default, Feb 10 2020, 15:33:01)

[bobby@pythonvm ~]$ 

Finally, I updated pip just to show that we can update something in this new install. Then I installed numpy to see if I could install a new package.

This is a quick and dirty post, but I want to remember these steps for myself and it might be helpful for someone who uses Redhat/Centos/OEL.
