Deployment Overview of Anaconda on Server¶

Prerequisites and Basic Requirements¶

To ensure a successful installation, the server must meet the following requirements:

Operating System: Compatible with Debian-based (e.g., Ubuntu) or RHEL-based (e.g., Rocky Linux) distributions.
Privileges: Root or sudo access is required to install system dependencies and execute the installer.
Network Access: The server must have outbound internet access to download packages from APT/YUM repositories and the Anaconda distribution archives.

The following table describes the domain template used for this deployment:

Parameter	Value
Prefix	`anaconda`
Domain	`hostkey.in`
Full template	`anaconda{Server_ID_from_Invapi}.hostkey.in`

The application is installed using a dedicated shell script provided by the Anaconda distribution. The installation process follows these steps:

Dependency Installation: The system installs necessary libraries for graphical and multimedia support, including libgl1-mesa-glx, libegl1-mesa, libXrandr2, libXss1, libXcursor1, libXcomposite1, libasound2, libXi6, libXtst6, libXdammage1, and curl (on Debian/Ubuntu) or equivalent packages such as alsa-lib and mesa-libGL (on RHEL).
Installer Download: The Anaconda3 installer script is downloaded from the official repository to the /root/ directory.
Integrity Verification: A SHA256 checksum is performed on the downloaded file to ensure data integrity.
Execution: The installation is executed in batch mode (-b) with a force reinstall flag (-f) to ensure a clean environment.
Environment Initialization: The Anaconda base environment is activated, and conda init is run to configure the shell environment. All packages within the distribution are updated to their latest versions via conda update --update-all.

The installed version of Anaconda is 2024.06-1.

Installation Directory: The application is primarily managed under the /root/anaconda3/ directory.
Installer Cleanup: To maintain system hygiene, the installation script (Anaconda3-*.sh) is automatically removed from the /root/ directory after a successful deployment.

The following actions are performed during or after the main installation:

Environment Configuration: The shell environment is modified to allow direct access to conda commands through the initialization of the base environment.
Post-Installation Cleanup: A finalization script is executed to complete any necessary system configurations required for the specific server environment.

To update the Anaconda distribution, the installation process must be re-run using the latest version's installer:

Download the desired version of the Anaconda3 Linux x86_64 shell script.
Execute the script using the following command to ensure a clean update:
```
bash Anaconda3-<version>-Linux-x86_64.sh -b -f
```

Re-initialize the environment by running:

source /root/anaconda3/bin/activate
conda init
conda update --update-all -y
