安装前准备

硬件要求

CPU最少2核
磁盘最少19G
文件系统EXT4 戓 XFS

关闭透明大页

echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled

确认操作系统版本是否支持

[root@innodb-cluster01 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.9 (Maipo)

清除缓存

echo 3 > /proc/sys/vm/drop_caches

设置ssh互信(执行下面的脚本)

#!/usr/bin/bash
   
SERVERS=("root@innodb-cluster01" "root@innodb-cluster02" "root@innodb-cluster03")	#修改为自己的"用户名@主机名/ip"
PASSWORD="******"	#输入用户的密码
keygen() {
sudo yum -y install expect
expect -c "
   spawn ssh-keygen -t rsa
   expect {
      *(~/.ssh/id_rsa):* { send -- \r;exp_continue}
      *(y/n)* { send -- y\r;exp_continue}
      *Enter* { send -- \r;exp_continue}
      *(y/n)* { send -- y\r;exp_continue}
      *Enter* { send -- \r;exp_continue}
      eof {exit 0}
   }
   expect eof
"
}
copy(){
expect -c "
   set timeout -1
   spawn ssh-copy-id $1
   expect {
      *(yes/no)* { send -- yes\r; exp_continue }
      *password:* { send -- $PASSWORD\r; exp_continue}
      eof {exit 0}
   }
   expect eof
"
}
ssh_copy_id_to_all(){
keygen ;
for host in ${SERVERS[@]}
do
      copy $host
done
}
ssh_copy_id_to_all

配置ntp

配置ulimit.conf

#vi /etc/sysctl.conf

# for oceanbase

fs.aio-max-nr=1048576

# 修改进程可以拥有的虚拟内存区域数量
vm.max_map_count = 655360

# 此处为 OceanBase 数据库的 data 目录
kernel.core_pattern = /data/ob/core-%e-%p-%t

#sysctl -p

规划磁盘

mkdir -p /data/ob/{data,redo,oceanbase}
data 	#数据盘
redo	#事务日志盘
oceanbase	#数据库安装盘

部署阶段

离线部署all-in-one

tar -xzf oceanbase-all-in-one-4.2.2.0-100010012024022719.el7.x86_64.tar.gz
cd oceanbase-all-in-one/bin
./install.sh
source ~/.oceanbase-all-in-one/bin/env.sh

使用OBD网页部署

obd web
start OBD WEB in 0.0.0.0:8680
please open http://192.168.56.20:8680

打开网页

选择OceanBase及配套工具

image

配置集群名称,选择需要部署的组件.

image

配置Zone信息、组件节点信息、部署用户信息、软件目录信息.

image

配置数据库信息,安装目录和端口信息.

image

安装前检查

image

安装完成

OCP Express安装失败,不影响数据库使用.
image

安装后的操作

根据安装页面上的信息登录数据库

[root@innodb-cluster01 ob]# obclient -h192.168.56.20 -P2883 -uroot -p'YW7cqUk{HO-9-Z' -Doceanbase -A

总结

  • 安装过程中OCP报错,目前没有找到原因,OCP是使用网页管理数据库的工具,暂时不影响命令行使用数据库.
