| 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_SCHEDNAME | ||
| +systemctl enable scx.service | ||
| ``` | ||
|
|
||
| - Start the service: | ||
|
|
||
| ``` | ||
| -systemctl start scx_SCHEDNAME | ||
| +systemctl start scx.service | ||
| ``` | ||
|
|
||
| Alternatively, you can use a shortened version of these commands: | ||
|
|
||
| ``` | ||
| -systemctl enable --now scx_SCHEDNAME | ||
| +systemctl enable --now scx.service | ||
| ``` | ||
|
|
||
| - To check the status of the service, use the following command: | ||
|
|
||
| ``` | ||
| -systemctl status scx_SCHEDNAME | ||
| +systemctl status scx.service | ||
| ``` | ||
|
|
