Systemd service
Download the oCIS binary of your preferred version and for your CPU architecture and operating system from download.owncloud.com.
Rename the downloaded binary to ocis and move it to /usr/bin/. As a next step, you need to mark it as executable with chmod +x /usr/bin/ocis.
When you now run ocis help on your command line, you should see the available options for the oCIS command.
Create the Systemd service definition for oCIS in the file /etc/systemd/system/ocis.service with following content:
[Unit]
Description=OCIS server
[Service]
Type=simple
User=root
Group=root
EnvironmentFile=/etc/ocis/ocis.env
ExecStart=ocis server
Restart=always
[Install]
WantedBy=multi-user.target
For reasons of simplicity we are using the root user and group to run oCIS which is not recommended. Please use a non-root user in production environments and modify the oCIS service definition accordingly.
In the service definition we referenced /etc/ocis/ocis.env as our file containing environment variables for the oCIS process.
In order to create the file we need first to create the folder /etc/ocis/ and then we can add the actual /etc/ocis/ocis.env with following content:
OCIS_URL=https://some-hostname-or-ip:9200
PROXY_HTTP_ADDR=0.0.0.0:9200
OCIS_INSECURE=false
OCIS_LOG_LEVEL=error
OCIS_CONFIG_DIR=/etc/ocis
OCIS_BASE_DATA_PATH=/var/lib/ocis
Since we set OCIS_CONFIG_DIR to /etc/ocis you can also place configuration files in this directory.
Please change your OCIS_URL in order to reflect your actual deployment. If you are using self-signed certificates you need to set OCIS_INSECURE=true in /etc/ocis/ocis.env.
oCIS will store all data in /var/lib/ocis, because we configured it so by setting OCIS_BASE_DATA_PATH. Therefore you need to create that directory and make it accessible to the user, you use to start oCIS.
Initialize the oCIS configuration by running ocis init --config-path /etc/ocis.
You can enable oCIS now by running systemctl enable --now ocis. It will ensure that oCIS also is restarted after a reboot of the host.
If you need to restart oCIS because of configuration changes in /etc/ocis/ocis.env, run systemctl restart ocis.
You can have a look at the logs of oCIS by issuing journalctl -f -u ocis.
