oceanbase demo版本部署

环境:
OS:Centos
oceabase:4.2

1.下载介质
https://www.oceanbase.com/softwarecenter
oceanbase-all-in-one-4.2.0.0-100120230821114201.el7.x86_64.tar.gz

2.解压安装
[root@host134 soft]# tar -xzf oceanbase-all-in-one-4.2.0.0-100120230821114201.el7.x86_64.tar.gz
[root@host134 soft]# cd oceanbase-all-in-one/bin
[root@host134 bin]# ./install.sh

Install Finished
=====================================================================
Setup Environment: source ~/.oceanbase-all-in-one/bin/env.sh
Start Web Service: obd web
Quick Start: obd demo
More Details: obd -h
====================================================================

[root@host134 bin]# source ~/.oceanbase-all-in-one/bin/env.sh

3.社区版部署
[root@host134 bin]# which obd
/root/.oceanbase-all-in-one/obd/usr/bin/obd
[root@host134 bin]# obd demo

4.连接数据库
通过 2881 端口直连数据库
[root@host134 bin]# obclient -h127.0.0.1 -P2881 -uroot@sys -Doceanbase -A

通过 ODP 代理访问数据库
[root@host134 bin]# obclient -h127.0.0.1 -P2883 -uroot@sys -Doceanbase -A

5.配置密码
使用 obd demo 命令快速部署的 OceanBase 数据库默认 root@sys 用户登录密码为空，您可参考如下命令为 demo 集群配置密码。
修改配置文件

[root@host134 oceanbase]#obd cluster edit-config demo

执行上述命令打开配置文件后，在配置文件中 oceanbase-ce（社区版）/oceanbase（企业版）组件下添加 root_password: xxxx，添加完成后保存退出。示例如下：

oceanbase-ce:
  servers:
    - 127.0.0.1
  global:
    home_path: /home/admin/oceanbase-ce
    ... # 省略部分配置项
    log_disk_size: 13G
    root_password: mysql123

保存后会有如下提升:
"/tmp/tmppgxnm6ik.yaml" 53L, 1056C written
Search param plugin and load ok
Parameter check ok
Save deploy "demo" configuration
Use `obd cluster reload demo` to make changes take effect.
Trace ID: abd00464-4581-11ee-8be2-525400c8dc1f
If you want to view detailed obd logs, please run: obd display-trace abd00464-4581-11ee-8be2-525400c8dc1f

这里需要执行obd cluster reload demo

[root@host134 oceanbase]# obd cluster reload demo

6.使用密码登录
[root@host134 oceanbase]# obclient -h 127.0.0.1 -P2881 -uroot@sys -Doceanbase -A -pmysql123

[root@host134 oceanbase]# obclient -h 127.0.0.1 -P2881 -uroot -Doceanbase -A -pmysql123

7.创建数据库(语句与mysql一样)
[root@host134 oceanbase]# obclient -h 127.0.0.1 -P2881 -uroot -A -pmysql123
obclient [(none)]>create database db_test;

建表(语句与mysql一样):
use db_test;
CREATE TABLE `tb_test02` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT COMMENT '主键id',
`name1` varchar(32) DEFAULT NULL,
`name2` varchar(32) DEFAULT NULL,
`name3` varchar(32) DEFAULT NULL,
`name4` varchar(32) DEFAULT NULL,
`name5` varchar(32) DEFAULT NULL,
`name6` varchar(32) DEFAULT NULL,
PRIMARY KEY (`id`)
);

8.创建用户
grant all privileges on *.* to 'hxl'@'%' identified by 'mysql' WITH GRANT OPTION;

9.pyhton操作oceabase
与mysql一样的操作,引入如下包即可
import pymysql
