+# 通过yum和systemd的方式安装OceanBase数据库
+如果你想在linux rpm平台上部署oceanbase，可以使用yum进行单节点安装，并通过systemd进行简单管理
+
+**注意**
+
+- 该方法仅能用做学习研究或测试使用；
+- 千万不要使用此方法用于带有重要数据的场景，比如生产环境。
+
+## 安装方法
+现在暂时只支持RPM平台系统，可以通过以下指令进行安装和启动：
+```bash
+yum install oceanbase-ce
+systemctl start oceanbase
+```
+
+## systemd介绍
+Systemd提供了自动化管理oceanbase的启动和停止，可以通过systemctl指令对oceanbase进行管理控制，例如：
+```bash
+systemctl {start|stop|restart|status} oceanbase
+```
+
+## 通过systemd配置oceanbase
+systemd提供了配置文件`/etc/oceanbase.cnf`,可以在启动前修改配置进行带参启动

+# 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
+```
+
+## 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.
