This document covers how to install, uninstall, and upgrade using the Scylla Unified Installer. The Unified Installer is recommended to be used when you do not have root privileges to the server. If you have root privileges, it is recommended to download the OS specific packages (RPMs and DEBs) and install them with the package manager (dnf and apt).
CentOS 7 (Only support root offline install)
Ubuntu 18.04 (developer-mode is used if NOFILE rlimit is too low)
For installation without root privileges, follow the instructions on Scylla Download Center
The unified package is based on a binary package; it’s not a RPM / DEB packages, so it doesn’t upgrade or downgrade by yum / apt. Currently, only install.sh of scylla supports the upgrade.
./install.sh --upgrade --nonroot
the installation script does not upgrade scylla-jmx and scylla-tools. You will have to do this separately.
To downgrade to your original Scylla version, use the Uninstall procedure above and then install the original Scylla packages.
