This guide will help you if, for example, you want to deploy a package like pymysql and it requires a Python version higher than the one provided by default on your hosting.

Preamble

• Anaconda is a free and open-source distribution of the programming languages Python and R. It aims to simplify package management and deployment.
• It is recommended to use Miniconda (a lightweight version of conda). It installs in your user space, avoiding any conflict with the system Python and not requiring administrator rights.
• Familiarize yourself with the official documentation.
• If necessary, local partners referenced by Infomaniak can handle these procedures: launch a free call for tenders; they take care of everything — also discover the role of the host.

1. Download the installer

For example, the 64-bit Linux version for Python 3.11.

user@server:~$ wget https://repo.anaconda.com/miniconda/Miniconda3-py311_23.10.0-1-Linux-x86_64.sh
--2024-03-10 12:00:00--  https://repo.anaconda.com/miniconda/Miniconda3-py311_23.10.0-1-Linux-x86_64.sh
Resolving repo.anaconda.com... 104.16.131.3, 104.16.130.3

2. Check the integrity (SHA256 Hash)

user@server:~$ sha256sum Miniconda3-py311_23.10.0-1-Linux-x86_64.sh
6c714a33ea348303f909194246990422e698889417d74b9714856b3e9a7e6c3a  Miniconda3-py311_23.10.0-1-Linux-x86_64.sh

3. Start the installation

The -b argument allows for a silent installation. By default, Miniconda will install in ~/miniconda3.

user@server:~$ bash Miniconda3-py311_23.10.0-1-Linux-x86_64.sh -b
PREFIX=/home/clients/your_client_hash/miniconda3

Solving environment: done
Executing transaction: done

4. Initialize and activate Conda

To use conda immediately and with each SSH connection:

user@server:~$ ~/miniconda3/bin/conda init bash
no change     /home/clients/your_client_hash/miniconda3/condabin/conda
...
modified      /home/clients/your_client_hash/.bashrc

user@server:~$ source ~/.bashrc

5. Install a package (example: pymysql)

Once activated, the (base) prefix appears before your command prompt. You can then install your tools without sudo or --user.

(base) user@server:~$ python -V
Python 3.11.5

(base) user@server:~$ pip install pymysql
