By the way this is the result after the elixir compilation:

Stop running the tests, just compile elixir.

Clone it as a regular user, change into the folder, checkout the version you want to install via git checkout $tag, then run make and sudo make install. It should install itself in a way that you do not need to alter the PATH.

Done and it seems to be working

Now I am following
https://hexdocs.pm/phoenix/installation.html#content
to install Phoenix which will take me a while since I also have to install Postgres

NO support for MySQL ?

24

There are drivers available for MySQL, nur PostgreSQL ist the preferred database, that’s why most tutorials use it.

25

I followed the instruction on https://afreshcloud.com/programming-elixir/installing-elixir-on-centos-7 to install elixir on my Redhat 7 Linux box.

26

This is a very relevant information, that in my opinion you could have included in your initial topic.

Why?

Because it could be one of the causes of your issues in your installation, specially if this proxy intercepts https requests, due to corporate policies.

27

Just a random blog post telling you how not to do it…

You never compile outside of a users folder, especially not in the folders “owned” by the system (meaning anything not /home, /tmp, /run, or explicitely owned by an application, but then you as a user still shouldn’t fiddle around with it.

If you really want to compile from source, then follow the official guide, which explicitely says to download a tarball from the github releases page, untar it and run make and sudo make install in it (though it could be more explicit about the latter part):

Next you should download source code (.zip, .tar.gz) of the latest release, unpack it and then run make inside the unpacked directory (note: if you are running on Windows, read this page on setting up your environment for compiling Elixir).

What it does though, is to explicitely mention, that compiling from master is only for the adventourus people.

28

First of all thank you very much for the patience: I now have a stable and clear installation procedure that I could replicate without any issue.

Erlang, Elixir and Phoenix are installed

Made my first app and now dealing with PostgreSQL and MySQL since I want to be able to work with both and check how (hope) simple is to go ffrom one to another with the same Phx app!
