Prometheus普罗米修斯之安装配置使用
Prometheus普罗米修斯之安装配置使用
一、基础环境
| 环境/组件 | 版本 | 下载地址 |
|---|---|---|
| 操作系统 | CentOS7.6 | |
| go | 1.15.7 | https://golang.org/dl/ |
| Prometheus | 2.6.0 | https://prometheus.io/download/#prometheus |
| Grafana | 5.4.2 | https://dl.grafana.com/oss/release/grafana-5.4.2-1.x86_64.rpm |
| exporter | https://prometheus.io/docs/instrumenting/exporters/ |
二、安装go
1.解压安装
1 | tar -C /usr/local/ -xvf go1.15.7.linux-amd64.tar.gz |
2.配置环境变量
1 | echo "export PATH=$PATH:/usr/local/go/bin" >> /etc/profile |
3.验证
1 | go version |
三、安装Prometheus
1.安装
1 | tar -C /usr/local/ -xvf prometheus-2.28.1.linux-amd64.tar |
2.注册服务
1 | tee /etc/systemd/system/prometheus.service <<EOF |
3.启动
1 | systemctl status prometheus |
4.登录验证
1 | 浏览器打开IP:9090端口即可打开普罗米修斯自带的监控页面 |
四、安装Grafana
普罗米修斯默认的页面可能没有那么直观，我们可以安装grafana使监控看起来更直观
1.安装
1 | yum install -y grafana-5.4.2-1.x86_64.rpm |
yum源无法使用时强制rpm安装
1 | rpm -ivh --nodeps grafana-5.4.2-1.x86_64.rpm |
2.启动
1 | systemctl daemon-reload |
3.访问grafana
浏览器访问IP:3000端口，即可打开grafana页面，默认用户名密码都是admin
初次登录会要求修改默认的登录密码
五、一些常用监控举例
1.监控linux机器（node-exporter）
被监控的机器安装node-exporter
1 | tar -zxvf node_exporter-0.17.0.linux-amd64.tar.gz -C /usr/local/ |
注册node-exporter 服务
1 | vim /lib/systemd/system/node_exporter.service |
1 | [Unit] |
启动服务
1 | systemctl status node_exporter |
普罗米修斯配置文件添加监控项
1 | vi /usr/local/Prometheus/prometheus.yml |
默认node-exporter端口为9100
添加如下配置:
1 | - job_name: 'node_exporter' |
重启普罗米修斯
1 | systemctl restart prometheus |
grafana导入画好的dashboard模板

如果没有任何显示，是grafana缺少相关显示需要用到的插件piechart，grafana的默认插件目录是/var/lib/grafana/plugins，可以将下载好的插件解压到这个目录，重启grafana即可
1 | service grafana-server restart |
再刷新grafana页面，即可看到我们刚才设置好的node监控
2.监控MySQL（mysqld-exporter）
被监控mysql机器安装mysqld-exporter
1 | tar -C /usr/local/ -xvf mysqld_exporter-0.11.0.linux-amd64.tar |
设置配置文件，user为数据库登录用户，password为这个用户的密码
1 | vi .my.cnf |
启动mysqld-exporter 也可注册服务与node-exporter同理
1 | /usr/local/mysqld_exporter-0.11.0.linux-amd64/mysqld_exporter --config.my-cnf="/usr/local/mysqld_exporter-0.11.0.linux-amd64/.my.cnf" & |
prometheus配置文件中加入mysql监控并重启
1 | vim /usr/local/Prometheus/prometheus.yml |
设置数据源
grafana界面添加mysql数据源
添加需要被监控的数据库及相关信息
导入已经画好的dashboard，数据源选择刚刚创建好的mysql数据源即可

3.监控Redis（redis_exporter）
安装redis_exporter
1 | tar -C /usr/local/ -xvf redis_exporter-v0.15.0.linux-amd64.tar |
启动redis_exporter
默认redis_exporter端口为9121
1 | /usr/local/redis_exporter redis//192.168.0.103:6379 & -web.listenaddress 192.168.0.103:9121 |
prometheus配置文件中加入redis监控并重启
1 | vim /usr/local/Prometheus/prometheus.yml |
