2.docker-compose安装prometheus

一、docker-compose安装

前期准备

# docker配置文件
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["http://hub-mirror.c.163.com"]
}
EOF

systemctl daemon-reload
systemctl restart docker

# 安装docker-compose
curl -L https://github.com/docker/compose/releases/download/2.26.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Last login: Wed Apr 24 12:10:08 2024 from 192.168.10.1
root@os:~# docker-compose -v
Docker Compose version v2.26.1

二、Docker-compose安装prometheus

1.创建prometheus监控的文件夹

mkdir /data/docker-prometheus -p

mkdir /data/docker-prometheus/{grafana,prometheus,alertmanager} -p

cd /data/docker-prometheus/

2.创建alertmanager的配置文件

cat > alertmanager/config.yml <<"EOF"
global:
  #163服务器
  smtp_smarthost: 'smtp.163.com:465'
  #发邮件的邮箱
  smtp_from: 'xc@163.com'
  #发邮件的邮箱用户名，也就是你的邮箱　　　　　
  smtp_auth_username: 'xc@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: 'xc@163.com'
    #当告警恢复后，是否发送邮件
    send_resolved: true
inhibit_rules:
 - source_match:
     severity: 'critical'
   target_match:
     severity: 'warning'
   equal: ['alertname', 'dev', 'instance']
EOF

3.创建grafana的配置文件

GF_SECURITY_ADMIN_PASSWORD=为grafana超级管理员admin的密码，根据实际修改

cat > grafana/config.monitoring <<EOF
GF_SECURITY_ADMIN_PASSWORD=password
GF_USERS_ALLOW_SIGN_UP=false
EOF

4.创建prometheus的配置文件

cat > prometheus/prometheus.yml << "EOF"
# 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
EOF

5.创建alter报警文件

cat > prometheus/alert.yml <<"EOF"
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"
EOF

6.创建docker-compose安装文件

docker镜像版本可以在dockerhub上查询，然后pull

#进入到prometheus目录
cd /data/docker-prometheus

#通过cat新建docker-compose.yaml文件
cat > docker-compose.yaml <<"EOF"
version: '3.3'
