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
