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 default version offered on your hosting.

Introduction

• Anaconda is a free and open-source distribution of the Python and R programming languages; 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 conflicts with the system Python and not requiring administrator privileges.
• Refer to the official documentation.

1. Download the installer

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

2. Verify integrity (SHA256 hash)

2. Contrôler l'intégrité (Hash SHA256)

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

3. Lancer l'installation

The -b argument enables a silent installation. By default, Miniconda will be installed 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
installation finished.

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

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

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