Bamboo as a Systemd Service

Make Atlassian Bamboo start as a Systemd service on Linux (CentOS).

Add a new bamboo user and group as explained in the Atlassian's tutorial.

useradd --create-home -c "Bamboo role account" bamboo

Make sure the binary and home directories are owned by the new user:

chown bamboo:bamboo /opt/atlassian/bamboo
chown bamboo:bamboo /var/atlassian/application-data/bamboo

Add the following to /etc/systemd/system/bamboo.service:

[Unit]
Description=Atlassian Bamboo Service
After=syslog.target network.target postgresql.service

[Service]
User=bamboo
Group=bamboo
Type=forking
Environment=BAMBOO_HOME=/var/atlassian/application-data/bamboo
ExecStart=/opt/atlassian/bamboo/bin/start-bamboo.sh
ExecStop=/opt/atlassian/bamboo/bin/stop-bamboo.sh

[Install]
WantedBy=multi-user.target

Reload the services via:

systemctl daemon-reload

To start/stop the service run:

systemctl start bamboo
systemctl stop bamboo

To enable the service to start after reboot:

systemctl enable bamboo
