- Setup
sudo scylla_setup --disks /dev/sdb
- Start scylla-server
sudo systemctl start scylla

./install.sh --nonroot --prefix `pwd`/install_root
- Setup
Skip for lack of sudo permission. Because scylla_setup requires sudo permission, some setup rely on systemd.
Some setup you can do manually or you can ask the Administrator:
- raid setup
- mount data disk
- set /etc/fstab to mount data disk automatically
- Start scylla
cd ./install_root

Some scylla users have poor permission, they can't write system directory, they can't change system configuration.
-
install.sh of scylla has an option
--noroot -
developer mode
scylla can't be started for: NOFILE rlimit too low (recommended setting 200000, minimum setting 10000; refusing to start.
- solution: enable developer-mode by appending '-developer-mode 1' to scylla cmdline
If you don't have sudo permission, you can't change systemd configuration in scylla_setup. Then you can't manage scylla/scylla-jmx by systemd, you have to start scylla/scylla-jmx from command-line.
Other services relay on systemd:
- housekeeping (it isn't disabled by default for install.sh)
- mount data disk
- need to manually set /etc/fstab to mount the data disk
The unified package is based on binary package, it's not a RPM / DEB packages, so it doesn't to upgrade or downgrade by yum / apt. Currently only install.sh of scylla supports to upgrade
./install.sh --upgrade ....
install.sh of scylla-jmx and scylla-tools don't support to upgrade.
Downgrade isn't supported by install.sh
