A Quick Start Guide
This guide provides instructions for running the SCX schedulers as a systemd service and checking its logs.
Getting Started
At the very beginning, configure the /etc/default/scx file:
-
in the SCX_SCHEDULER variable, select the scheduler you are interested in
-
in the SCX_FLAGS variable, specify the flags you want to add. To do this, execute and read what flags you can add.
scx_SCHEDNAME --help
To start the SCX scheduler at boot, you need to run the systemd service as root. Here are the steps:
- Enable the service:
systemctl enable scx.service
- Start the service:
systemctl start scx.service
Alternatively, you can use a shortened version of these commands:
systemctl enable --now scx.service
- To check the status of the service, use the following command:
systemctl status scx.service
Override global configuration
It is possible to override the global scx settings using systemd environment
variables SCX_SCHEDULER_OVERRIDE
and SCX_FLAGS_OVERRIDE
.
Example:
systemctl set-environment SCX_SCHEDULER_OVERRIDE=scx_rustland
systemctl set-environment SCX_FLAGS_OVERRIDE="-s 10000"
systemctl restart scx
If you want to restore the default value from the /etc/default/scx
file execute:
systemctl unset-environment SCX_SCHEDULER_OVERRIDE
systemctl unset-environment SCX_FLAGS_OVERRIDE
systemctl restart scx
Checking journald Logs
- To view the logs, use the following command:
journalctl -u scx.service
- To view the logs of the current session use the command
journalctl -u scx.service -b 0
