To set up an OpenRC service to run at the "login" level in OpenRC-init based Linux distributions, you need to create a service script and define the runlevel at which it should start. Here are the steps:
1. **Create the Service Script**:
Create a script for your service in the `/etc/init.d/` directory. You can name it anything you like. For example, let's call it "my_service."
```bash
sudo nano /etc/init.d/my_service
```
Inside this script, you should define the start and stop actions for your service. Here's a simple example:
```bash
#!/sbin/openrc-run
depend() {
need net
}
start() {
ebegin "Starting my_service"
# Your start commands here
eend $?
}
stop() {
ebegin "Stopping my_service"
# Your stop commands here
eend $?
}
```
Make sure to replace `# Your start commands here` and `# Your stop commands here` with the actual commands for starting and stopping your service.
2. **Set the Runlevel**:
OpenRC uses runlevels to determine when a service should start. The "login" runlevel corresponds to runlevel `default` on many systems. To set your service to run at the "login" level, you can create a symlink in the appropriate runlevel directory:
```bash
sudo ln -s /etc/init.d/my_service /etc/runlevels/default/my_service
```
3. **Start the Service**:
To start the service immediately, run:
```bash
sudo rc-service my_service start
```
4. **Enable the Service on Boot**:
To have the service start automatically at boot, you can enable it:
```bash
sudo rc-update add my_service default
```
Now, your "my_service" should start at the "login" runlevel.
Please note that the exact steps may vary depending on your specific OpenRC-based distribution. Be sure to consult the documentation or specific guides for your distribution if you encounter any issues.
