# Running a Service at Boot
Your `.service` file should look like this:
```
[Unit]
Description=Spark service
[Service]
ExecStart=/path/to/spark/sbin/start-all.sh
[Install]
WantedBy=multi-user.target
```
Now, take a few more steps to enable and use the `.service` file:
1. Place it in `/etc/systemd/system` folder with say a name of `myfirst.service`
2. Make sure that your script executable with:
```
chmod u+x /path/to/spark/sbin/start-all.sh
```
3. Start it:
```
sudo systemctl start myfirst
```
4. Enable it to run at boot:
```
sudo systemctl enable myfirst
```
5. Stop it:
```
sudo systemctl stop myfirst
```
#### Notes
1. You don't need to launch Spark with `sudo` in your service, as the default service user is already root.
2. Look at the links below for more `systemd` options.
#### Moreover
Now what we have above is just rudimentary, here is a complete setup for spark:
```
[Unit]
Description=Apache Spark Master and Slave Servers
After=network.target
After=systemd-user-sessions.service
After=network-online.target
[Service]
User=spark
Type=forking
ExecStart=/opt/spark-1.6.1-bin-hadoop2.6/sbin/start-all.sh
ExecStop=/opt/spark-1.6.1-bin-hadoop2.6/sbin/stop-all.sh
TimeoutSec=30
Restart=on-failure
RestartSec=30
StartLimitInterval=350
StartLimitBurst=10
[Install]
WantedBy=multi-user.target
```
To setup the service:
```
sudo systemctl start spark.service
sudo systemctl stop spark.service
sudo systemctl enable spark.service
```
#### Further reading
Please read through the following links. Spark is a complex setup, so you should understand how it integrates with Ubuntu's init service.
