操作系统

关闭透明大页

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

关闭防火墙

systemctl disable firewalld

关闭selinux

[root@obnode-000-071 /]# cat /etc/selinux/config # This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled

用户与ssh互信

新增用户

useradd -U admin -d /home/admin -s /bin/bash
mkdir -p /home/admin
passwd admin

给admin增加sudo

vi /etc/sudoers

vim /etc/sudoers
添加如下内容：
Same thing without a password
%wheel        ALL=(ALL)       NOPASSWD: ALL
admin       ALL=(ALL)       NOPASSWD: ALL

目录与属主

mkdir /data
chown -R admin:admin /data
chown -R admin:admin /home/admin

互信

配置告警通道

https://www.oceanbase.com/docs/common-ocp-1000000000584847

就配置一个飞书群机器人webhook

webhook 还是一如既往的好用，测试立马就收到消息了

添加主机

接管集群

先给每个主机安装 agent

https://www.oceanbase.com/docs/common-ocp-1000000000584687

• 一番折腾，原来是这个包

• 虽然已经配了sudo免密，但是还是得在添加主机时使用root用户才行，不然一直处于新提交的状态

这个连接有常用的启停操作命令

接管 metaDB 集群

发现接管不上，创建主机时新增了一个IDC，IDC的region和这个sys_region不一样

群上说不支持主机所属应用和机房的修改，这就难受了，推倒重新部署一个单节点的ocp再看看

铲了

单节点OCP

单节点ocp部署后，集群已经接管在OCP

租户正常

所在主机正常

部署ocp时已经安装proxy，这里无法为ocp的oceanbase在创建一个proxy

创建3节点的oceanbase

添加主机

创建集群

提交集群配置进行创建

成功创建集群

创建obproxy

通过obproxy可以登录登录oceanbase

几个个注意点

部署OCP时，memory_limit设置太小

memory_limit 必须大于 ocp_meta_tenant 和 ocp_monitor_tenant的内存之和

Create tenant ocp_meta ok
Create tenant ocp_monitor x
[ERROR] resource not enough: memory (Avail: 6029M, Need: 8192M)

log_disk_size 太小

https://ask.oceanbase.com/t/topic/35606467

log_disk_size 默认是 memory_limit的3倍，比如我的主机内存是16G，如果选择了自动分配内存，大概是10G左右，那么log_disk_size需要30G，按照页面的提示输入个24GB，后面安装铁定会报错

[ERROR] OBD-5000: create resource pool ocp_monitor_pool unit=‘ocp_monitor_unit’, unit_num=1, zone_list=(‘zone1’,‘zone2’,‘zone3’) execute failed
[ERROR] ocp-server-ce-py_script_start-4.2.1 RuntimeError: (4733, ‘zone ‘zone1’ resource not enough to hold 1 unit. You can check resource info by views: DBA_OB_UNITS, GV$OB_UNITS, GV$OB_SERVERS.\nserver ‘“192.168.1.165:2882”’ LOG_DISK resource not enough\n’)
[ERROR] ocp-server-ce start failed

ocp_agent

在OCP安装agent后，systemctl查看到agent状态是不正确的

[root@obnode-000-072 ~]# systemctl status ocp_agent
● ocp_agent.service - start ocp_agentLoaded: loaded (/usr/lib/systemd/system/ocp_agent.service; bad; vendor preset: disabled)Active: failed (Result: exit-code) since Mon 2024-04-22 10:11:01 CST; 8h agoProcess: 1114 ExecStart=/home/admin/ocp_agent/bin/ocp_agentctl start (code=exited, status=255)Apr 22 10:10:38 obnode-000-072 systemd[1]: Starting start ocp_agent...

重启后则正常

[root@obnode-000-072 ~]# systemctl is-enabled ocp_agent
enabled

[root@obnode-000-072 ~]# ps -ef|grep agent

服务命令行重启

https://ask.oceanbase.com/t/topic/35602977

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/admin/oceanbase/lib
cd /home/admin/oceanbase && bin/observer

如果没有lib包报错如下：

[admin@obnode-000-072 oceanbase]$ ./bin/observer 
./bin/observer: error while loading shared libraries: libmariadb.so.3: cannot open shared object file: No such file or directory
