### prometheus 安装 ###

*  1，Ubuntu 16.04安装prometheus
 *  2，测试启动
 *   *  2.1，运行前检查配置文件
     *  2.2，修改\`prometheus.yml\`获取监控数据
     *  2.3，prometheus开机启动
 *  3，node\_exporter安装
 *   *  3.1，node\_exporter开机启动
     *  3.1，监控多个主机
 *  4，prometheus查看targets
 *  5，数据可视化显示
 *   *  5.1，Grafana导入面板

# 1，Ubuntu 16.04安装prometheus #

*  `prometheus-2.18.1.darwin-amd64.tar.gz`

# tar -zxvf prometheus-2.18.1.linux-amd64.tar.gz

*  设置环境变量
 *  `vim /root/.bashrc`

#prometheus
    export PATH=$PATH:/root/prometheus-2.18.1.linux-amd64

# 2，测试启动 #

prometheus --config.file=/root/prometheus-2.18.1.linux-amd64/prometheus.yml

*  `0.0.0.0:9090`

## 2.1，运行前检查配置文件 ##

# ./promtool check config prometheus.yml
    Checking prometheus.yml
      SUCCESS: 0 rule files found

## 2.2，修改`prometheus.yml`获取监控数据 ##

*  `vim prometheus.yml`增加`job_name`

scrape_configs:
      # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
      - job_name: 'prometheus'
    
        # metrics_path defaults to '/metrics'
        # scheme defaults to 'http'.
    
        static_configs:
        - targets: ['localhost:9090']
    
    
        # node_exporter
      - job_name: 'node'
        static_configs:
        - targets: ['127.0.0.1:9100']

## 2.3，prometheus开机启动 ##

# vim /lib/systemd/system/prometheus.service

# cat /lib/systemd/system/prometheus.service
    [Unit]
    Description=prometheus service
    
    [Service]
    User=root
    ExecStart=/root/prometheus-2.18.1.linux-amd64/prometheus --config.file=/root/prometheus-2.18.1.linux-amd64/prometheus.yml
    
    TimeoutStopSec=10
    Restart=on-failure
    RestartSec=5
    
    [Install]
    WantedBy=multi-user.target

# systemctl daemon-reload
    # systemctl enable prometheus.service
    Created symlink /etc/systemd/system/multi-user.target.wants/prometheus.service → /lib/systemd/system/prometheus.service.
    # systemctl start prometheus.service
    # systemctl status prometheus.service

# 3，node\_exporter安装 #

*  `node_exporter-1.0.0.linux-amd64.tar.gz`

# tar -zxvf node_exporter-1.0.0.linux-amd64.tar.gz
    # cd node_exporter-1.0.0.linux-amd64/
    # ./node_exporter

*  访问`ip:9100`  
    ![在这里插入图片描述][20200603161941655.png]
 *  增加配置`prometheus`
 *  `vim prometheus.yml`

- job_name: 'node'
        static_configs:
        #- targets: ['localhost:9090']
        - targets: ['127.0.0.1:9100']

## 3.1，node\_exporter开机启动 ##

# cat /lib/systemd/system/node_exporter.service
    [Unit]
    Description=node_exporter service
    
    [Service]
    User=root
    ExecStart=/root/node_exporter-1.0.0.linux-amd64/node_exporter
    
    TimeoutStopSec=10
    Restart=on-failure
    RestartSec=5
    
    [Install]
    WantedBy=multi-user.target

# systemctl daemon-reload
    # systemctl enable node_exporter.service
    # systemctl start node_exporter.service
    # systemctl status node_exporter.service

## 3.1，监控多个主机 ##

*  192.168.0.3 只运行`node_exporter`
 *  192.168.0.2 运行有`prometheus`
 *  配置`prometheus.yml`
 *  `targets`配置多个IP地址

# cat prometheus.yml
        static_configs:
        - targets: ['localhost:9090']
    
    
        # node_exporter
      - job_name: 'node'
        static_configs:
        - targets: ['127.0.0.1:9100','192.168.0.3:9100']

# 4，prometheus查看targets #

# 5，数据可视化显示 #

## 5.1，Grafana导入面板 ##

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTA5NTM2OTI_size_16_color_FFFFFF_t_70 2]

*  id为`8919`
 *  数据源选择`prometheus`
