Download the Anaconda installation binary and run through the installation. During installation ensure you specify that your Anaconda install location should be /opt/miniconda3.

curl --output anaconda.sh https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh

bash anaconda.sh

Add the Anaconda executable to your $PATH in your .bashrc file by inserting the following export line at the bottom.

vi ~/.bashrc

export PATH="/opt/miniconda3/bin:$PATH"

Log out and log back in to refresh your profile. Then, check to see if you can use the conda commands. You may also need to run conda init bash to initialize Anaconda.

If you prefer to not have (base) show up in your prompt while no conda environment is activate, simply do the following command and log out/log in:

conda config --set auto_activate_base false
