promethus+grafana监控ceph集群

1、安装grafana
1、配置yum源文件

cat >>/etc/yum.repos.d/grafana.repo <<EOF
[grafana]
name=grafana
baseurl=https://packages.grafana.com/oss/rpm
repo_gpgcheck=1
enabled=1
gpgcheck=1

2.通过yum命令安装grafana

yum -y install grafana

3.启动grafana并设为开机自启

systemctl start grafana-server.service 
systemctl enable grafana-server.service

2、安装promethus
1、下载安装包，下载地址

https://prometheus.io/download/

2、解压压缩包

tar fvxz prometheus-2.14.0.linux-amd64.tar.gz

3、将解压后的目录改名

mv prometheus-2.14.0.linux-amd64 /opt/prometheus

4、查看promethus版本

/opt/prometheus/prometheus --version

5、配置系统服务启动

cat >> /etc/systemd/system/prometheus.service <<EOF
[Unit]
Description=Prometheus Monitoring System
Documentation=Prometheus Monitoring System
[Service]
ExecStart=/opt/prometheus/prometheus \
  --config.file /opt/prometheus/prometheus.yml \
