# 规划

IP	角色	版本
10.10.0.13	prometheus-server	2.10
10.10.0.11	node_exporter	0.18.1
10.10.0.12	node_exporter	0.18.1

# 下载

官网：https://prometheus.io/download/

[root@prometheus-server ~]# wget https://github.com/prometheus/prometheus/releases/download/v2.40.7/prometheus-2.40.7.linux-amd64.tar.gz

# 创建运行用户

[root@prometheus-server ~]# groupadd -r prometheus
[root@prometheus-server ~]# useradd -r -g prometheus -d / -s /sbin/nologin -c "prometheus user" prometheus

# 安装

安装这里介绍两种方式：

1、docker部署

2、二进制部署（本文采用）

# 二进制部署

[root@prometheus-server ~]# tar -xf prometheus-2.40.7.linux-amd64.tar.gz
[root@prometheus-server ~]# mkdir /etc/prometheus
[root@prometheus-server ~]# mkdir /var/lib/prometheus
[root@prometheus-server ~]# cp prometheus-2.40.7.linux-amd64/prometheus /usr/local/bin/
[root@prometheus-server ~]# cp prometheus-2.40.7.linux-amd64/prometheus.yml /etc/prometheus/
[root@prometheus-server ~]# chown -R prometheus:prometheus /etc/prometheus
[root@prometheus-server ~]# chown -R prometheus:prometheus /var/lib/prometheus/
[root@prometheus-server ~]# vim /usr/lib/systemd/system/prometheus.service

参数解释：

笔记

--config.file=/etc/prometheus/prometheus.yml ### prometheus配置文件

--storage.tsdb.path=/var/lib/prometheus ### prometheus 存储数据路径

--storage.tsdb.retention=15d ### prometheus采集数据保留时间

--web.read-timeout=5m ### 请求链接的最大等待时间

--web.max-connections=10 ### 最大链接数

--query.max-concurrency=20 ### 最大支持的并发查询量

--query.timeout=2m ### 单个查询超时时间

--web.enable-lifecycle ### 热加载

# docker部署

官方介绍：https://github.com/prometheus/prometheus/tree/master (opens new window)

docker方式部署需要先创建prometheus.yml文件

[root@prometheus-server ~]# mkdir /opt/prometheus/
[root@prometheus-server ~]# vim /opt/prometheus/prometheus.yml

# my global config
global:
  scrape_interval:     15s # 抓取数据的周期，默认为1min 
  evaluation_interval: 15s # 更新rules文件的周期，默认为1min
  # scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
  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"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
    static_configs:
    - targets: ['localhost:9090']

## 运行
[root@prometheus-server ~]# docker run -d -p 9090:9090 --user="root" --name prometheus -v /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml -v /opt/prometheus/data:/prometheus prom/prometheus

笔记

1、--user：指定运行用户

2、需要宿主机创建prometheus.yml配置文件

# 浏览器访问

启动后，直接浏览器访问端口9090,这样，prometheus服务就安装好了。

编辑

#Docker
