二进制安装Prometheus

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."

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