阿里龙蜥OS 8.6离线安装单机版OceanBase 4.3（社区版）

一、下载安装包

提前或者找一台能连外网的电脑先去官网下载安装包
官方下载地址https://www.oceanbase.com/softwarecenter

推荐下载OceanBase All in One版本

二、拷贝至服务器上

下载完成后拷贝至服务器上。

三、运行安装命令

1.解压包

bash 复制代码

#提前切入到存放压缩文件的路径下，依次执行下面的命令
tar -xzf oceanbase-all-in-one-4.4.1_20251020.el7.x86_64.tar.gz
cd oceanbase-all-in-one/bin/
./install.sh
source ~/.oceanbase-all-in-one/bin/env.sh

2.修改配置文件

bash 复制代码

#进入配置文件目录下
cd ~/.oceanbase-all-in-one/obd/usr/obd/example
#查看官方提供的配置文件清单
ls

能看到大概有这些配置文件

官方对于配置文件的用途做了如下说明：

小规格开发模式，适用于个人设备（内存不低于 8 GB）

本地单机部署配置样例：mini-local-example.yaml

单机部署配置样例：mini-single-example.yaml

单机部署 + ODP 配置样例：mini-single-with-obproxy-example.yaml

分布式部署 + ODP 配置样例：mini-distributed-with-obproxy-example.yaml

分布式部署 + ODP + OCP Express 配置样例：default-components-min.yaml

分布式部署全部组件：all-components-min.yaml

专业开发模式，适用于高配置 ECS 或物理服务器（可用资源不低于 16 核 64 GB）

本地单机部署配置样例：local-example.yaml

单机部署配置样例：single-example.yaml

单机部署 + ODP 配置样例：single-with-obproxy-example.yaml

分布式部署 + ODP 配置样例：distributed-with-obproxy-example.yaml

分布式部署 + ODP + OCP Express 配置样例：default-components.yaml

分布式部署全部组件：all-components.yaml

    #***************************上面根据自己机器配置设置*********
    #***************************下面的推荐设置***************
    #修改登录密码
    root_password: a12345678. # root user password, can be empty
    #修改数据库实例名
    appname: myoceanbase
    #设置开机自启动
    enable_auto_start: true

如果后面修改过配置需要执行

bash 复制代码

obd cluster reload myoceanbase

如果数据库服务没启动可以

bash 复制代码

obd cluster start myoceanbase

PS:如果启动报错

bash 复制代码

[ERROR] OBD-1007: (127.0.0.1) The value of the ulimit parameter "open files" must not be less than 20000 (Current value: 1024), Please execute `echo -e "* soft nofile 20000\n* hard nofile 20000" >> /etc/security/limits.d/nofile.conf` as root in 127.0.0.1. if it dosen't work, please check whether UsePAM is yes in /etc/ssh/sshd_config.

执行命令

bash 复制代码

#修改配置文件
echo -e "* soft nofile 20000\n* hard nofile 20000" >> /etc/security/limits.d/nofile.conf
#重启sshd
systemctl restart sshd
#再启动oceanbase数据库
obd cluster start myoceanbase

四、链接测试

我使用的是navicat,选择mysql链接方式，测试连接通过。
