1-3 docker 安装 prometheus

#创建文件夹，父级目录也被自动创建
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'

安装 docker

bash 复制代码

#设置下载目录
export DOWNLOAD_URL="http://mirrors.163.com/docker-ce"
curl -fssL https://get.docker.com/ | sh

检查版本

bash 复制代码

docker -v 
或
systemctl status docker

安装Docker-compose

bash 复制代码

# 下载
curl -L https://get.daocloud.io/docker/compose/releases/download/1.29.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

# 设置文件具备执行权限
chmod +x /usr/local/bin/docker-compose

# 查看版本
docker-compose --version

二、Docker-compose 安装 Prometheus

1、【方式一】手动创建 docker-compose 和配置文件

创建prometheus监控的文件夹

bash 复制代码

#切换到root用户
sudo -i
mkdir /data/docker-prometheus -p
mkdir /data/docker-prometheus/{grafana,prometheus,alertmanager} -p
cd /data/docker-prometheus/

创建alertmanager的配置文件 - config.yml

bash 复制代码

global:
  #163服务器
  smtp_smarthost: 'smtp.163.com:465'
  #发邮件的邮箱
  smtp_from: 'cdring@163.com'
  #发邮件的邮箱用户名，也就是你的邮箱　　　　　
  smtp_auth_username: 'cdring@163.com'
  #发邮件的邮箱密码
  smtp_auth_password: 'your-password'
  #进行tls验证
  smtp_require_tls: false

route:
  group_by: ['alertname']
  # 当收到告警的时候，等待group_wait配置的时间，看是否还有告警，如果有就一起发出去
  group_wait: 10s
  #  如果上次告警信息发送成功，此时又来了一个新的告警数据，则需要等待group_interval配置的时间才可以发送出去
  group_interval: 10s
  # 如果上次告警信息发送成功，且问题没有解决，则等待 repeat_interval配置的时间再次发送告警数据
  repeat_interval: 10m
  # 全局报警组，这个参数是必选的
  receiver: email

receivers:
- name: 'email'
  #收邮件的邮箱
  email_configs:
  - to: 'cdring@163.com'
inhibit_rules:
 - source_match:
     severity: 'critical'
   target_match:
     severity: 'warning'
   equal: ['alertname', 'dev', 'instance']

新建grafana的配置文件 - config.monitoring

bash 复制代码

# admin登录密码为password
GF_SECURITY_ADMIN_PASSWORD=password
GF_USERS_ALLOW_SIGN_UP=false

新建prometheus的配置文件 - prometheus.yml

bash 复制代码

# 全局配置
global:
  scrape_interval:     15s # 将搜刮间隔设置为每15秒一次。默认是每1分钟一次。
  evaluation_interval: 15s # 每15秒评估一次规则。默认是每1分钟一次。

# Alertmanager 配置
alerting:
  alertmanagers:
  - static_configs:
    - targets: ['alertmanager:9093']

# 报警(触发器)配置
rule_files:
  - "alert.yml"

# 搜刮配置
scrape_configs:
  - job_name: 'prometheus'
    # 覆盖全局默认值，每15秒从该作业中刮取一次目标
    scrape_interval: 15s
    static_configs:
    - targets: ['localhost:9090']
  - job_name: 'alertmanager'
    scrape_interval: 15s
    static_configs:
    - targets: ['alertmanager:9093']
  - job_name: 'cadvisor'
    scrape_interval: 15s
    static_configs:
    - targets: ['cadvisor:8080']
      labels:
        instance: Prometheus服务器 

  - job_name: 'node-exporter'
    scrape_interval: 15s
    static_configs:
    - targets: ['node_exporter:9100']
      labels:
        instance: Prometheus服务器

创建alert报警文件 - alert.yml

bash 复制代码

groups:
- name: Prometheus alert
  rules:
  # 对任何实例超过30秒无法联系的情况发出警报
  - alert: 服务告警
    expr: up == 0
    for: 30s
    labels:
      severity: critical
    annotations:
      summary: "服务异常,实例:{{ $labels.instance }}"
      description: "{{ $labels.job }} 服务已关闭"

新建docker-compose.yaml文件

bash 复制代码

2、【方式二 - 推荐】通过克隆gitee代码安装

bash 复制代码

mkdir /mnt/docker/
cd /mnt/docker/
git clone https://gitee.com/linge365/docker-prometheus.git
cd docker-prometheus

运行命令

bash 复制代码

cd /data/docker-prometheus
docker-compose up -d

检查容器

bash 复制代码

docker ps

检查接口

bash 复制代码

ss -lntp|egrep "3000|9090|9100|9093"
