前言
在上一节docker部署oceanbase单机的实验中遇到了不少问题，初始化的oceanbase占用资源过多，导致部分命令执行失败，因此本节内容采用手动方式部署，合理分配现有资源，做到知其然知其所以然。
一、服务器环境
本次实验采用单台服务器部署，服务器信息如下：
服务器IP | 系统 | cpu | 内存 | 磁盘 | 安装目录 |
10.40.204.170 | centos 7 | 8 | 16 | 170G | /oceanbase |
内核相关参数与上一节相似，为解决镜像使用obd启动时产生的两个waning，调整了相关参数
[root@oceanbase ~]# cat /etc/sysctl.conf | grep fs.
fs.file-max = 655350
fs.aio-max-nr=1048576二、oceanbase相关角色说明
oceanbase相关角色说明
角色 | 说明 |
OBD | 自动化部署软件 |
OBSERVER | ob数据库 |
OBPROXY | ob访问反向代理 |
OBCLIENT | ob命令行客户断 |
安装包下载网址：
https://open.oceanbase.com/softwareCenter/community
三、安装oceanbase各软件包
[root@oceanbase oceanbase]# ls -lh
