Providing guidelines to configure service unit file for the systemd on Linux system for NoSQL database

This discussion provides an example for educational purposes only.

This document provides an example for starting and stopping using standard Linux commands. Use the standard Linux command to stop or start the Storage Node Agent.

systemctl start nosqlora
systemctl status nosqlora
systemctl stop nosqlora

to start automatically

systemctl enable nosqlora

You can find here an example of nosqlora.service based on the scripts in examples-nosql-cluster-deployment

[Unit]
Description=Oracle Nosql Database
After=syslog.target network.target

[Service]
Type=simple
RemainAfterExit=yes
User=opc
Group=opc
Environment=KVHOME=/home/opc/nosql/kv-24.3.9
Environment=KVROOT=/home/opc/nosql/kvroot
ExecStart=bash /home/opc/examples-nosql-cluster-deployment/script/start.sh
ExecStop=bash /home/opc/examples-nosql-cluster-deployment/script/stop.sh

[Install]
WantedBy=multi-user.target

We recommend working with your Operating System team to adapt to your administration policies/standards and your installation.

When doing the upgrade, do not forget to disable the automatic startup and activate only after modifying the script to use the new version. (KVHOME env variable in my example)

systemctl disable nosqlora

In the same way, if you want to automate the start of the HTTP Proxy, you can see an example here, which is for educational purposes only. Adapt to your administration policies

proxynosqlora.service

[Unit]
Description=Oracle Nosql Database HTTP Porxy
After=syslog.target network.target

[Service]
Type=simple
RemainAfterExit=yes
User=opc
Group=opc
Environment=KVHOME=/home/opc/nosql/kv-24.3.9
Environment=KVPROXY=/home/opc/proxy
Environment=KVSTORE=OUG
Environment=PROXYPORT=8080
ExecStart=bash /home/opc/examples-nosql-cluster-deployment/script/start-http.sh

[Install]
WantedBy=multi-user.target
