OceanBase Docker体验

1. 实验一：OceanBase Docker体验

通过 OceanBase Docker 容器，快速的体验 OceanBase 的 自动化部署过程，以及了解 OceanBase 集群安装成功后的目录特点和使用方法。

1. 1. Docker镜像
      1. 实验环境
         1. 实验环境说明

1台OCP 5台OBSERVER

aarch64 Kylin Linux Advanced Server release V10 (Sword)

CPU 16核

内存 64G

磁盘划分(lvm、fdisk)

用途 实验环境

/docker docker安装目录 200G

/home ob的安装目录 100G

/data/1 数据盘 110G

/data/log1 日志盘（事务日志） 200G

1. 1. 1. 1. 实验环境配置
2. 设置chrony服务器

ocp：

sh -c 'echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6'

local clock

server 127.127.1.0

fudge 127.127.1.0 stratum 10

启动时钟服务器 Systemctl start chronyc

更新最新时钟 chronyc sources

1. 建立用户，挂载文件系统（略）
2. 修改limits限制、内核参数、关闭防火墙
3. 网卡配置

cd /etc/sysconfig/network-scripts

cat ifcfg-enp1s0

1. 配置ssh免密

ocp-ob-obp-odc-antman_20220506_arm/common/ssh/

vi address.txt 编辑IP、用户名、密码、hostname

./step1_init.sh

./step2_testlogin.sh

./step3_sethostname.sh

./step4_obssh.sh

1. 下载对应版本 t-oceanbase-antman和oceanbase-all-in-one
   1.
   1.
   1. 安装ocp

1、安装t-oceanbase-antman

2、创建admin用户

/root/t-oceanbase-antman/clonescripts/clone.sh -u

3、配置内核参数（/etc/sysctl.conf）

/root/t-oceanbase-antman/clonescripts/clone.sh -c -r ocp

4、安装依赖包

/root/t-oceanbase-antman/clonescripts/clone.sh -m -r ocp

5、安装docker

/root/t-oceanbase-antman/clonescripts/clone.sh -i

6、上传docker镜像

docker load -i ocp323.arm.tar.gz

7、配置obcluster.conf文件

/root/t-oceanbase-antman/init_obcluster_conf.sh 选1

8、安装部署前预检查

/root/t-oceanbase-antman/clonescripts/precheck.sh -m ocp

9、安装

sh install.sh -i 1-8

1. 1. 1. Docker环境
         1. Docker环境
2. 下载docker镜像

wget https://download.docker.com/linux/static/stable/aarch64/docker-24.0.6.tgz

1. 解压下载好的压缩包

tar xf docker-24.0.6.tgz

1. 移动解压文件到/usr/bin 目录中

mv docker/* /usr/bin/

1. 启动docker

dockerd

1. 1. 1. 1. Docker安装
2. 执行命令：docker pull oceanbase/obce-mini 下载所需镜像
3. 启动docker命令：docker run -p 2881:2881 --name obce-mini -d -e OB_HOME_PATH="/root/obce/" -e OB_TENANT_NAME="obmysql" oceanbase/obce-mini
4. 进入容器：docker exec -it obce-mini bash
   1. 使用 OBD 命令OceanBase 集群部署
      1. OBD安装

1. 检查OBD安装包

下载地址https://open.oceanbase.com/softwareCenter/community

1. 安装obd

Rpm --ivh ob-deploy-2.3.0-4.el7.aarch64.rpm

1. 将OceanBase rpm离线软件包加入本地镜像

obd mirror clone obproxy-ce-4.2.0.0-7.el7.aarch64.rpm obproxy-ce-4.2.0.0-7.el7.aarch64.rpm libobclient-2.2.2-3.el7.aarch64.rpm

1. 1. 1. 集群配置文件
