Prometheus容器化部署的实践方案
环境
| 主机名 | IP地址 | 服务 |
|---|---|---|
| prometheus | 192.168.237.137 | prometheus、grafana |
| node-exporter | 192.168.237.131 | node_exporter |
容器化部署prometheus
1、安装docker
[root@prometheus ~]# docker version Client: Docker Engine - Community Version: 20.10.11 API version: 1.41 Go version: go1.16.9 Git commit: dea9396 Built: Thu Nov 18 00:36:58 2021 OS/Arch: linux/amd64 Context: default Experimental: true Server: Docker Engine - Community Engine: Version: 20.10.11 API version: 1.41 (minimum version 1.12) Go version: go1.16.9 Git commit: 847da18 Built: Thu Nov 18 00:35:20 2021 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.4.12 GitCommit: 7b11cfaabd73bb80907dd23182b9347b4245eb5d runc: Version: 1.0.2 GitCommit: v1.0.2-0-g52b36a2 docker-init: Version: 0.19.0 GitCommit: de40ad0
2、运行prometheus容器
//拉取镜像 [root@prometheus ~]# docker pull prom/prometheus Using default tag: latest latest: Pulling from prom/prometheus 3cb635b06aa2: Pull complete 34f699df6fe0: Pull complete 33d6c9635e0f: Pull complete f2af7323bed8: Pull complete c16675a6a294: Pull complete 827843f6afe6: Pull complete 3d272942eeaf: Pull complete 7e785cfa34da: Pull complete 05e324559e3b: Pull complete 170620261a59: Pull complete ec35f5996032: Pull complete 5509173eb708: Pull complete Digest: sha256:cb9817249c346d6cfadebe383ed3b3cd4c540f623db40c4ca00da2ada45259bb Status: Downloaded newer image for prom/prometheus:latest docker.io/prom/prometheus:latest //在/opt目录下提供prometheus的默认配置文件 [root@prometheus ~]# ls /opt/ prometheus.yml //运行容器 ##--restart always 总是重启，开机自启 ## 将本地提供的配置文件映射到容器，ro 容器内只读 [root@prometheus ~]# docker run --name prometheus -d --restart always -p 9090:9090 -v /opt/prometheus.yml:/etc/prometheus/prometheus.yml:ro prom/prometheus:latest a0ba5535f0ea3b0f44574fd237802f2ef19f4624c3752c3bf8122a4d79a26428 [root@prometheus ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a0ba5535f0ea prom/prometheus:latest "/bin/prometheus --c…" 11 seconds ago Up 11 seconds 0.0.0.0:9090->9090/tcp, :::9090->9090/tcp prometheus //查看端口 [root@prometheus ~]# ss -anltu Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port Process tcp LISTEN 0 128 0.0.0.0:22 0.0.0.0:* tcp LISTEN 0 128 0.0.0.0:9090 0.0.0.0:* tcp LISTEN 0 128 [::]:22 [::]:* tcp LISTEN 0 128 [::]:9090 [::]:*
使用ip+9090/targets访问prometheus默认网页
部署node_exporter
//下载安装包
[root@node-exporter ~]# wget https://github.com/prometheus/node_exporter/releases/download/v1.3.0/node_exporter-1.3.0.linux-amd64.tar.gz
[root@node-exporter ~]# ls
anaconda-ks.cfg node_exporter-1.3.0.linux-amd64.tar.gz
//解压
[root@node-exporter ~]# tar xf node_exporter-1.3.0.linux-amd64.tar.gz -C /usr/local/
[root@node-exporter ~]# mv /usr/local/node_exporter-1.3.0.linux-amd64/ /usr/local/node_exporter
[root@node-exporter ~]# ls /usr/local/
bin etc games include lib lib64 libexec node_exporter sbin share src
//编写service文件，启动并开机自启
[root@node-exporter ~]# cat /usr/lib/systemd/system/node_exporter.service

## node-exporter部署成功就可以在Prometheus主机上添加节点进行监控
添加节点到prometheus中
修改本地prometheus.yml文件
//修改配置文件 [root@prometheus ~]# tail -8 /opt/prometheus.yml scrape_configs: # The job name is added as a label `job=` to any timeseries scraped from this config. - job_name: "prometheus" static_configs: - targets: ["localhost:9090"] - job_name: "centos" //指定一个工作名称 static_configs: - targets: ["192.168.237.131:9100"] //指定node-exporter节点的IP和端口号 ## 如果有多个节点 - job_name: "centos" static_configs: - targets: - "192.168.237.131:9100" - "192.168.237.132:9100" - "192.168.237.133:9100" //重启容器，重新读取配置文件 [root@prometheus ~]# docker restart prometheus prometheus [root@prometheus ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a0ba5535f0ea prom/prometheus:latest "/bin/prometheus --c…" 26 minutes ago Up 3 seconds 0.0.0.0:9090->9090/tcp, :::9090->9090/tcp prometheus
访问prometheus默认网页
成功添加节点
部署grafana画图工具
//拉取grafan/grafan官方镜像 [root@prometheus ~]# docker pull grafana/grafana Using default tag: latest latest: Pulling from grafana/grafana 97518928ae5f: Pull complete 5b58818b7f48: Pull complete d9a64d9fd162: Pull complete 4e368e1b924c: Pull complete 867f7fdd92d9: Pull complete 387c55415012: Pull complete 07f94c8f51cd: Pull complete ce8cf00ff6aa: Pull complete e44858b5f948: Pull complete 4000fdbdd2a3: Pull complete Digest: sha256:18d94ae734accd66bccf22daed7bdb20c6b99aa0f2c687eea3ce4275fe275062 Status: Downloaded newer image for grafana/grafana:latest docker.io/grafana/grafana:latest [root@prometheus ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE prom/prometheus latest a3d385fc29f9 12 days ago 201MB grafana/grafana latest 9b957e098315 2 weeks ago 275MB //使用官方grafana镜像运行容器 [root@prometheus ~]# docker run -d --name grafana -p 3000:3000 --restart always grafana/grafana 0b5986fc63442538a6fae845e5d1b8afc78caec4f4bdd81ca3623eb1329ad562 [root@prometheus ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 0b5986fc6344 grafana/grafana "/run.sh" 4 seconds ago Up 2 seconds 0.0.0.0:3000->3000/tcp, :::3000->3000/tcp grafana a0ba5535f0ea prom/prometheus:latest "/bin/prometheus --c…" 33 minutes ago Up 6 minutes 0.0.0.0:9090->9090/tcp, :::9090->9090/tcp prometheus //查看端口 [root@prometheus ~]# ss -anltu Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port Process tcp LISTEN 0 128 0.0.0.0:22 0.0.0.0:* tcp LISTEN 0 128 0.0.0.0:3000 0.0.0.0:* tcp LISTEN 0 128 0.0.0.0:9090 0.0.0.0:* tcp LISTEN 0 128 [::]:22 [::]:* tcp LISTEN 0 128 [::]:3000 [::]:* tcp LISTEN 0 128 [::]:9090 [::]:*
