Centos7.9 单机安装OceanBase 社区版

news 2025/9/26 11:16:43

目录

1.环境准备

2.安装依赖和系统配置

2.1关闭防火墙

2.2关闭 SELinux

2.3 安装基础依赖

2.4  解压并安装 OceanBase All-in-One 包

2.5 一键启动单机 OceanBase 集群

2.6 连接并验证数据库

3.java程序连接OceanBase

     工作有用到OceanBase,为方便学习研究，本地虚拟机安装OceanBase 社区版，更能直接感受OceanBase的功能，同时方便平时工作中自测。

1.环境准备

项目要求
操作系统CentOS 7.9 x86_64
CPU4 核及以上
内存8 GB 以上（建议 12GB+）
磁盘50 GB 以上（建议 SSD）
网络可访问外网（用于下载依赖）

 首先到官网下载：https://www.oceanbase.com/softwarecenter

查询系统是什么CPU类型，下载对应的安装包

我的系统信息：

[root@node01 oceanbase-ce]# hostnamectlStatic hostname: node01Icon name: computer-vmChassis: vmMachine ID: cd4406118bce4895b15ce6dea6173badBoot ID: 3fe9a6841eee451095add67c4c5c7331Virtualization: vmwareOperating System: CentOS Linux 7 (Core)CPE OS Name: cpe:/o:centos:centos:7Kernel: Linux 3.10.0-1160.el7.x86_64Architecture: x86-64
[root@node01 oceanbase-ce]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
[root@node01 oceanbase-ce]#

所以下载x86，如果是 ARM 服务器选 ARM版-el7

oceanbase-all-in-one-4.3.5_bp4_20250910.el7.x86_64.tar.gz

然后上传到服务器

2.安装依赖和系统配置

2.1关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

2.2关闭 SELinux

# 临时关闭
setenforce 0# 永久关闭
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

2.3 安装基础依赖

yum install -y wget tar net-tools

2.4  解压并安装 OceanBase All-in-One 包

tar -xzf oceanbase-all-in-one-4.3.5_bp4_20250910.el7.x86_64.tar.gz# 进入目录
cd oceanbase-all-in-one/bin# 安装 OBD（OceanBase Deployer）和依赖
./install.sh
[root@node01 bin]# ./install.sh 
install obd as root

+--------------------------+------+------------------------+--------+demo running
This is a basic setup with minimal resources, good for testing and learning. For full OceanBase performance, please destroy this cluster and redeploy by using `obd pref`
Trace ID: c4e55e4a-99e4-11f0-b6c0-000c29a85316
If you want to view detailed obd logs, please run: obd display-trace c4e55e4a-99e4-11f0-b6c0-000c29a85316
[root@node01 bin]# ls
env.sh  install.sh  uninstall.sh
[root@node01 bin]#

 重点，日志输入会打印密码，一定要记下来

obclient -h127.0.0.1 -P2883 -uroot -p'ShhnyW0vcL6VycJgM4lB' -Doceanbase -A

同时有监控地址，日志输出：

Connect to Prometheus ok

+--------------------------------------+-------+--------------+--------+

实际上我的虚拟机IP地址是：192.168.180.25，但日志输入并不是这个IP，可能是缓存原因，这个10.100。51.30是我以前设置过的IP，所以用：

http://192.168.180.25:9090/alerts?search=

可以打开界面看监控

http://192.168.180.25:3000/login

输入账号密码，配置

  • 左侧菜单 → Configuration（齿轮图标）→ Data Sources

  • 找到名为 "OceanBase" 或 "Prometheus" 的数据源

  • 点击进入，检查 URL 应该是：http://192.168.180.25:9090/

可以查看OceanBase运行状态了

2.6 连接并验证数据库

  • -h：主机（本机）
  • -P：端口（2883 是 OBProxy 端口）
  • -u：用户（root@sys，格式：用户名@租户名）
  • -A：跳过权限检查

首次登录密码为空，直接回车即可。

obclient -h127.0.0.1 -P2883 -uroot -p'ShhnyW0vcL6VycJgM4lB' -Doceanbase -A

安装成功了，并成功连接：

查看数据库状态

-- 查看租户
SHOW TENANT;-- 查看数据库
SHOW DATABASES;-- 切换到 test 数据库
USE test;-- 创建测试表
CREATE TABLE t1(id INT, name VARCHAR(20));
INSERT INTO t1 VALUES (1, 'hello');
SELECT * FROM t1;

使用SQLyog客户端连接：

3.java程序连接OceanBase

引入maven坐标

		<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency>

程序代码

package com.example.ob;import java.sql.*;public class TestOB {public static void main(String[] args) throws Exception {String url = "jdbc:mysql://192.168.180.25:2883/test?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC";String user = "root";String password = "ShhnyW0vcL6VycJgM4lB";try (Connection conn = DriverManager.getConnection(url, user, password)) {Statement stmt = conn.createStatement();ResultSet rs = stmt.executeQuery("SELECT * FROM t1");while (rs.next()) {System.out.println(rs.getInt("id") + ", " + rs.getString("name"));}}}
}

至此，安装成功。
