系统基础环境优化—前提条件

部署前所有节点都需要进行优化:

https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000000035594

#调整OBserver的网卡MTU为9000


yum install -y yum-utils perl gcc automake autoconf libtool make git


#其它节点开始进行优化:

OBD开始部署OBserver集群

由于OceanBase的副本数量默认是根据zone的数量来分配的,所以配置文件要把5台服务器分成5个zone,2台zone放在机房1,2台zone放在机房2,2台zone放在机房3,机器和机房的数量形成2:2:1的比例。即是同一个集群,两地三中心五副本模式!也可以是同城三中心五副本模式!

#然后下载OCP,并解压修改配置文件。
