It has been a hell of a run, but here is the detailed procedure:
WARNING: ONLY USE THE PACKAGE INSTALLER OF POINT 1 AS LAST RESOURCE, IT CAN CAUSE MANY PROBLEMS.
For example: using it to install composer will downgrade your php binary to v5 permanently, and there is nothing you can do to fix it unless creating a new node, if you decide to use it, first clone your node to have a backup in case it destroyes everything.
Install this package installer following the instructions here: https://github.com/jelastic-jps/packages-installer :
Then use it to install gcc.
We need to install anaconda in order to update git and curl to a version recent enough to make brew at least run (src: https://stackoverflow.com/a/52561058/12181662 ) :
curl https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh > Miniconda.sh bash Miniconda.sh -b -p ~/conda
Use anaconda to install git and curl (src: https://www.reddit.com/r/linux4noobs/comments/lzdo9n/comment/gq1fhak/?utm_source=share&utm_medium=web2x&context=3 ) :
source /var/www/conda/bin/activate
conda update conda
conda install git
conda install curl
conda deactivate
echo 'export PATH="/var/www/conda/bin:$PATH"' >> ~/.bash_profile
export PATH="/var/www/conda/bin:$PATH"
install brew locally (src: https://brew.sh/ ) :
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
echo 'eval "$(/var/www/.linuxbrew/bin/brew shellenv)"' >> /var/www/.bash_profile
eval "$(/var/www/.linuxbrew/bin/brew shellenv)"
echo 'export HOMEBREW_CURL_PATH="/var/www/conda/bin/curl"' >> ~/.bash_profile
export HOMEBREW_CURL_PATH="/var/www/conda/bin/curl"
echo 'export HOMEBREW_GIT_PATH="/var/www/conda/bin/git"' >> ~/.bash_profile
export HOMEBREW_GIT_PATH="/var/www/conda/bin/git"
install the most recent version of gcc using brew (src: https://github.com/Homebrew/homebrew-core/issues/101919#issuecomment-1162740031 ) :
brew install gcc#5
brew install --force-bottle gcc
fix brew install for the non-root locations (src: https://github.com/orgs/Homebrew/discussions/3421#discussioncomment-3126807 ) :
echo 'export HOMEBREW_RELOCATE_BUILD_PREFIX=1' >> /var/www/.bash_profile
export HOMEBREW_RELOCATE_BUILD_PREFIX=1
enjoy! Example: brew install composer
Also you can try to run this is you face any errors during installation of anything:
brew link --overwrite libxcrypt
