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
