Running with Forever

You can use the Forever node package as well. (This assumes you've installed the app to /opt/auto-fork-sync)

forever start --minUptime 1000 \
    --spinSleepTime 1000 \
    --workingDir /opt/auto-fork-sync \
    -a -w -l /opt/auto-fork-sync/.forever/forever.log \
    -o /opt/auto-fork-sync/.forever/out.log \
    -e /opt/auto-fork-sync/.forever/err.log \
    -c "npm start" ./

Running with Systemd

You can also run this service as a daemon. This sample assumes that the app is installed in /opt/auto-fork-sync.

Create a service file in /etc/systemd/system/auto-fork-sync.service and add the following contents

[Unit]
Description=GitHub Probot - Auto Fork Sync
After=network-online.target

[Service]
PIDFile=/opt/auto-fork-sync/auto-fork-sync.pid
User=node
Group=node
Restart=on-failure
# do chdir before running the service
WorkingDirectory=/opt/auto-fork-sync/
ExecStart=/usr/bin/npm start
KillSignal=SIGQUIT
# limit CPU and RAM quota for our service
CPUAccounting=true
CPUQuota=10%
MemoryAccounting=true
MemoryLimit=250M

[Install]
WantedBy=multi-user.target

Once you've created the file you will be able to enable, disable, start, stop, restart and check the status of the application.

systemctl status auto-fork-sync.service

systemctl enable auto-fork-sync.service

systemctl start auto-fork-sync.service
