As an example, you can try to start the installation with unattended mode; just specify what you want to install and what you do not want to install; to see the list of possible components for Plesk Obsidian v18.0.68 version, check
Code:
# wget https://autoinstall.plesk.com/plesk-installer
# chmod +x ./plesk-installer
# ./plesk-installer list PLESK_18_0_68 --components
[...]
advisor [install] - Advisor
xovi [install] - SEO Toolkit
imunify360 [install] - Imunify
[...]
Final example,
Code:
# ./plesk-installer install PLESK_18_0_68 --preset Recommended --without imunify360 git
It is based on
Installing Plesk for Linux in Unattended Mode.
BTW, if you install Plesk with a component you want to uninstall, it could also removed when the installation is finished:
