Deployment Overview of Anaconda on Server¶

Prerequisites and Basic Requirements¶

The following requirements must be met before deploying Anaconda on the server:

Operating System: Debian-based (e.g., Ubuntu) or RHEL-based (e.g., CentOS, Rocky Linux) distributions.
Privileges: Root access or sudo privileges are required to install system dependencies and the Anaconda distribution.
Architecture: 64-bit Linux (x86_64).
Network Access: The server must have outbound internet access to download the installer from repo.anaconda.com and to update packages.
System Dependencies:
Debian/Ubuntu: libgl1-mesa-glx, libegl1-mesa, libxrandr2, libxss1, libxcursor1, libxcomposite1, libasound2, libxi6, libxtst6, libxdamage1, curl.
RHEL/CentOS: libXcomposite, libXcursor, libXi, libXtst, libXrandr, alsa-lib, mesa-libEGL, libXdamage, mesa-libGL, libXScrnSaver.

Upon successful installation, the following directory structure is established:

Installation Root: /root/anaconda3
Binary Executables: /root/anaconda3/bin
Environment Configuration: /root/.bashrc (modified by conda init)
Installer Script Location: /root/Anaconda3-2024.06-1-Linux-x86_64.sh (removed post-installation)

The deployment involves downloading the official installer, verifying its integrity, and executing it in batch mode.

Update System Packages:
On Debian systems, update the APT cache and upgrade existing packages.
On RHEL systems, ensure the package manager is ready for dependency installation.
Install Dependencies:
Install the required graphical and audio libraries listed in the Prerequisites section.
Download the Installer:
The installer is downloaded to /root/Anaconda3-2024.06-1-Linux-x86_64.sh from the official repository.
The file permissions are set to u=rwx,g=r,o=r with root ownership.
Verify Integrity:
The SHA256 checksum of the downloaded installer is calculated to ensure file integrity.
Execute Installation:
The installer is run in batch mode (-b) with force reinstallation enabled (-f).
Command: bash /root/Anaconda3-2024.06-1-Linux-x86_64.sh -b -f
Initialize and Update:
The base environment is activated.
conda init is executed to configure the shell.
All packages within the base environment are updated using conda update --update-all -y.
Cleanup:
The installation script is removed from the /root directory.

User Context: The installation is performed as the root user.
File Permissions: The installer script is set to be executable by the owner and readable by group and others before execution.
Post-Installation: The installer script is deleted immediately after the process completes to reduce the attack surface.
Shell Configuration: The conda init command modifies the shell configuration file (typically /root/.bashrc) to automatically activate the base environment upon login.

Anaconda is not a system service managed by systemd or init. It is a user-space environment.

Activation:
To activate the base environment in a new shell session, run:
```
source /root/.bashrc
```
Alternatively, explicitly activate the base environment:
```
source /root/anaconda3/bin/activate
```
Updating Packages:
To update all packages in the current environment:
```
conda update --update-all -y
```
Updating the Distribution:
To update the conda package manager itself:
```
conda update conda
```
Deactivation:
To deactivate the current environment:
```
conda deactivate
```
