基于ARM的OceanBase4.2双节点安装

软硬件环境

前提条件

oceanbase-all-in-one-4.2.1.0-100120231013145059.el7.aarch64.tar.gz安装介质一个，

在两个节点进行解压，并执行./bin/install.sh

确定两边都有OBD环境与离线安装的介质 ，运行 obd mirror list local

准备好调整集群配置文件ob.yaml

安装执行

正式配置集群，运行以下命令obd cluster deploy ob-cluster -c ./ob.yaml

过程中可能会提示when production_mode is True,你可以选择把production_mode 变成false

obd cluster edit-config ob-cluster

启动集群服务obd cluster start ob-cluster

进往集群服务obclient -h127.0.0.1 -P2881 -uroot -Doceanbase -A -p'123456'

基于ARM的OceanBase双节点安装成功！！
