OBAgent 部署配置文件可以跟 OceanBase 集群部署配置文件部署在一起也可以后期单独部署此处为单独部署。
vim obagent-only.yaml

obclient -h 192.168.152.30 -urootsys#obcluster-3zones -P3883 -p0EI5N08d -c -A oceanbase执行如下操作
SHOW GRANTS FOR monitor;
grant select on oceanbase.* to monitor identified by fLyaqjrp2R; #和配置文件里密码一致然后再次查看monitor用户权限结果如下
MySQL [oceanbase] SHOW GRANTS FOR monitor;
--------------------------------------------
| Grants for monitor% |
--------------------------------------------
| GRANT USAGE ON *.* TO monitor |
| GRANT SELECT ON oceanbase.* TO monitor |

wget https://mirrors.aliyun.com/oceanbase/community/stable/el/8/x86_64/obagent-1.2.0-4.el8.x86_64.rpm
su - admin
obd mirror clone /tmp/obsoft/obagent-1.2.0-4.el8.x86_64.rpm
obd cluster deploy obagent-only -c obagent-only.yaml
obd cluster start obagent-only部署完成查看和验证obagent
[adminobce01 ~]$ obd cluster list

-------------------------------------------------使用curl测试agent 密码在配置文件中提前配置了
curl --user admin:eIYf7NAZeT -L http://192.168.152.31:8088/metrics/ob/basic3obagnet重启
i.直接重启某个节点的 OBAgentkill -9 pidof monagentcd /home/admin/obagent nohup bin/monagent -c conf/monagent.yaml ii.如果是集中重启使用 OBD 命令重启obd cluster restart obagent_onlyiii.如果 OBAgent 是跟 OceanBase 一起部署的则只能重启 obagent 组件obd cluster restart obce-3zones-obagent -c obagent4部署prometheus OBAgent 启动后会自动生成 Prometheus 配置文件被放在 OBAgent 安装目录下/home/admin/obagent/conf/prometheus_config/。可供 Prometheus直接使用。 scrape_interval 1s 抓取间隔 evaluation_interval 10s 评估规则间隔 rule_files rules/*rules.yaml 报警规则 scrape_configs – 抓取配置
prometheus下载https://prometheus.io/download/
解压安装并启动
tar zxvf prometheus-xxxxxxxx.linux-amd64.tar.gz
cp /home/admin/obagent/conf/prometheus_config/promethous.yaml /home/admin/prometheus-2.37.5.linux-amd64/
./prometheus ---config.fileprometheus.yaml netstat -nltp 可以看到9090端口开着
浏览器直接访问192.168.152.30:9090/graph5grafana安装
下载安装
wget https://dl.grafana.com/enterprise/release/grafana-enterprise-9.3.6-1.x86_64.rpm
sudo yum install grafana-enterprise-9.3.6-1.x86_64.rpm 使用
sudo systemctl start grafana-server.service
