-# Installing OceanBase Database via yum and systemd
-If you want to deploy OceanBase on a Linux RPM platform, you can use yum for single-node installation and simple management with systemd.
-
-**WARNING**
-
- The installation method is just used for study or test;
- You should not deploy it with important data as it is not used in production environment.
-
-## Installation Method
-Now systemd only support RPM platform and you can install and run oceanbase service using the following command:
-```bash
-yum install oceanbase-ce
-systemctl start oceanbase
-```
-You can set the OceanBase service to start automatically on boot using the following command:
-```bash
-systemctl enable oceanbase
-```
-
-## Overview of systemd
-Systemd provides automatic oceanbase startup and shutdown. It also enables manual server management using the systemctl command. For example:
-```bash
-systemctl {start|stop|restart|status} oceanbase
-```
-
-## Oceanbase configuration by systemd
-Systemd provide `/etc/oceanbase.cnf` to config oceanbase before startup.
