下载源
https://prometheus.io/download/ https://github.com/prometheus/prometheus/releases/download/v2.28.1/prometheus-2.28.1.linux-amd64.tar.gz https://github.com/prometheus/prometheus/releases/download/v2.28.1/prometheus-2.28.1.windows-amd64.zip https://github.com/prometheus/alertmanager/releases/download/v0.22.2/alertmanager-0.22.2.linux-amd64.tar.gz https://github.com/prometheus/alertmanager/releases/download/v0.22.2/alertmanager-0.22.2.windows-amd64.zip
一、监控系统的基本概念术语
job：唯一标识每个接入的业务方，可以在每个job下面添加多个监控任务
task：表示一个具体的监控任务，包含访问数据地址，采集数据周期等
metric：表示监控项，描述要监控内容的含义，相当于map里面的key
tag：表示标签，用于给metric打标记分类，方便后期绘图和配置报警
二、数据采集方式
·insight直接采集（强烈推荐）
·推送数据到中间件，insight间接采集
·直接推送数据到insight数据库（不推荐）
1、安装rz和wget
yum -y install lrzsz wget
2、下载二进制tar包
wget https://github.com/prometheus/prometheus/releases/download/v2.28.1/prometheus-2.28.1.linux-amd64.tar.gz
3、解压到指定目录，解压改名
tar -zxvf prometheus-2.28.1.linux-amd64.tar.gz -C /usr/local/ cd /usr/local/ mv prometheus-2.28.1.linux-amd64 prometheus cd prometheus/ 查看版本 ./prometheus --version
4、编辑启动配置文件
[root@localhost ~]# cat /usr/local/prometheus/prometheus.yml | grep -Ev "^$|#" global: alerting: alertmanagers: - static_configs: - targets: rule_files: scrape_configs: - job_name: 'prometheus' static_configs: - targets: ['192.168.35.130:1919']
5、关闭防火墙或者开放对应端口
systemctl stop firewalld setenforce 0
6、启动服务，创建用户、组和存储数据地址
./prometheus groupadd prometheus useradd -g prometheus -s /sbin/nologin prometheus chown -R prometheus:prometheus /usr/local/prometheus/ mkdir -p /home/prometheus/prometheus-data chown -R prometheus:prometheus /home/prometheus/prometheus-data/
7、编辑自启动文件
[root@localhost ~]# cat /usr/lib/systemd/system/prometheus.service [Unit] Description=Prometheus Documentation=https://prometheus.io/ After=network.target [Service] # Type设置为notify时，服务会不断重启 Type=simple User=prometheus # --storage.tsdb.path是可选项，默认数据目录在运行目录的./dada目录中 #ExecStart=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml --storage.tsdb.path=/home/prometheus/prometheus-date ExecStart=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml --storage.tsdb.path=/home/prometheus/prometheus-date --web.listen-address=:1919 Restart=on-failure [Install] WantedBy=multi-user.target
设置自启动查看状态
systemctl enable prometheus systemctl start prometheus systemctl status prometheus
当前系统状态
[root@localhost system]# systemctl daemon-reload #系统重载 非必要不用 [root@localhost system]# systemctl reset-failed prometheus.service #重建失败服务 非必要不用 [root@localhost system]# systemctl restart prometheus [root@localhost system]# systemctl status prometheus ● prometheus.service - Prometheus Loaded: loaded (/usr/lib/systemd/system/prometheus.service; enabled; vendor preset: disabled) Active: active (running) since 二 2021-07-27 11:26:02 CST; 3s ago Docs: https://prometheus.io/ Main PID: 10887 (prometheus) CGroup: /system.slice/prometheus.service └─10887 /usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml --storage.... 7月 27 11:26:02 localhost.localdomain prometheus[10887]: level=info ts=2021-07-27T03:26:02.453Z caller=head.g...t=9 7月 27 11:26:02 localhost.localdomain prometheus[10887]: level=info ts=2021-07-27T03:26:02.483Z caller=head.g...t=9 7月 27 11:26:02 localhost.localdomain prometheus[10887]: level=info ts=2021-07-27T03:26:02.495Z caller=head.g...t=9 7月 27 11:26:02 localhost.localdomain prometheus[10887]: level=info ts=2021-07-27T03:26:02.495Z caller=head.g...t=9 7月 27 11:26:02 localhost.localdomain prometheus[10887]: level=info ts=2021-07-27T03:26:02.495Z caller=head.g...4ms 7月 27 11:26:02 localhost.localdomain prometheus[10887]: level=info ts=2021-07-27T03:26:02.497Z caller=main.g...GIC 7月 27 11:26:02 localhost.localdomain prometheus[10887]: level=info ts=2021-07-27T03:26:02.497Z caller=main.g...ed" 7月 27 11:26:02 localhost.localdomain prometheus[10887]: level=info ts=2021-07-27T03:26:02.498Z caller=main.g...yml 7月 27 11:26:02 localhost.localdomain prometheus[10887]: level=info ts=2021-07-27T03:26:02.499Z caller=main.go:1…?s 7月 27 11:26:02 localhost.localdomain prometheus[10887]: level=info ts=2021-07-27T03:26:02.499Z caller=main.g...s." Hint: Some lines were ellipsized, use -l to show in full.

至此，监控安装完成 prometheus_target_interval_length_seconds{quantile="0.99"}
