Docker 部署 Prometheus + Grafana
资源清单#
主机 | IP |
---|---|
Prometheus + Grafana | 10.0.0.1 |
软件 | 版本 |
---|---|
docker | 20.10.12 |
docker-compose | 1.23.1 |
Prometheus | 2.18.1 |
Grafana | 7.2.1 |
Pushgateway | 1.4.2 |
Alertmanager | 0.11.0 |
node-exporter | 1.3.1 |
一、Docker
安装#
1. 使用国内 yum
源#
# yum install -y yum-utils device-mapper-persistent-data lvm2# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
2. 卸载旧版本的 docker
#
## 如果主机上已经有docker存在且不是想要安装的版本,需要先进行卸载。# yum remove -y docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate \ docker-logrotate \ docker-selinux \ docker-engine-selinux \ docker-engine \ container*
3. 安装 Docker20.10
版本#
# yum -y install docker-ce-20.10.12-3.el7 docker-ce-cli-20.10.12-3.el7
4. 设置镜像加速#
# mkdir /etc/docker# vi /etc/docker/daemon.json
{ "registry-mirrors": ["https://xxxxxxxxx.mirror.aliyuncs.com"]}
5. 启动 docker
#
# systemctl start docker# systemctl enable docker# systemctl status docker
二、Docker-compose
安装#
1. Docker-compose
安装#
## github.com 可能访问超时,可以使用下面的获取下载下来后上传服务器即可# curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# curl -k "https://dl.cactifans.com/zabbix_docker/docker-compose" -o /usr/bin/docker-compose
# chmod a+x /usr/bin/docker-compose
2. 查看 docker-compose
版本#
# docker-compose version
三、安装 prometheus + grafana + pushgateway
#
1. 获取 docker-compose.yaml
#
## 使用下面的开源项目,可以跳过这个步骤,使用下面的 docker-compose.yaml 文件# cd /opt/# git clone https://github.com/evnsio/prom-stack.git# cd prom-stack
2. 编辑 docker-compose.yml
文件#
version: "3"services:
pushgateway: #image: prom/pushgateway:v0.4.0 image: prom/pushgateway:v1.4.2 container_name: pushgateway command: --persistence.file=/pushgateway/pushgateway.data ports: - 9091:9091 volumes: - /data/pushgateway:/pushgateway

###############node-exporter############### node-exporter: image: "prom/node-exporter:v1.3.1" #hostname: node-exporter container_name: node-exporter ports: - '9100:9100' volumes: - /etc/localtime:/etc/localtime:ro - /proc:/host/proc:ro - /sys:/host/sys:ro - /:/rootfs:ro - /etc/hostname:/etc/hostname:ro restart: always network_mode: host command: - '--path.procfs=/host/proc' - '--path.sysfs=/host/sys' - '--path.rootfs=/rootfs'
3. 创建服务挂载目录#
# mkdir -pv /data/{pushgateway,prometheus,alertmanager,grafana}
# mkdir /data/prometheus/{alerts,data}
## 设置grafana持久化存储文件权限# chown 472:472 -R /data/grafana/
4. 编辑配置文件#
a | prometheus.yml
#
# vim /data/prometheus/prometheus.yml
# my global configglobal: scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute. evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute. # scrape_timeout is set to the global default (10s).
# Attach these labels to any time series or alerts when communicating with # external systems (federation, remote storage, Alertmanager). external_labels: monitor: 'edocyun-prom-stack'
# Alertmanager configurationalerting: alertmanagers: - static_configs: - targets: - alertmanager:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.rule_files: # - "first_rules.yml" # - "second_rules.yml"
scrape_configs: - job_name: 'prom-stack' static_configs: - targets: - prometheus:9090 - pushgateway:9091 - alertmanager:9093 - grafana:3000
- job_name: 'node-exporter' static_configs: - targets: - 10.0.0.1:9100 ## 需要主机部署 node-exporter 服务
b | alertmanager.yml
#
# vim /data/alertmanager/alertmanager.yml
global: smtp_smarthost: 'localhost:25' smtp_from: 'alertmanager@example.org' smtp_auth_username: 'alertmanager' smtp_auth_password: 'password'
route: group_by: ['cluster'] receiver: team-a
receivers:- name: 'team-a' email_configs: - to: 'team-a@example.org'
5. 启动服务#
# docker-compose -f docker-compose.yml pull# docker-compose -f docker-compose.yml up -d
grafana 使用默认用户名密码 admin password 登陆
a | 查看服务安装情况#
# docker-compse ps
# docker ps -a
6. 使用 curl
生成测试数据#
- 可以使用 $RANDOM 来生成随机数
# while true; do echo "mymetric $RANDOM" | curl --data-binary @- http://localhost:9091/metrics/job/my-push-job sleep 1done
“mymetric” 就是这个被监控的指标,这个监控指标推送到 pushgateway 比较简洁直观的
- 在浏览器里打开 pushgateway: “http://10.0.0.1:9091/”
可以看到测试的数据已经进入 pushgateway 了
