## 组件安装 ##

### node-exporter ###

#下载镜像
    docker pull prom/node-exporter
    #运行
    docker run -d \
     -p 9100:9100 \
      quay.io/prometheus/node-exporter
    #运行
    docker run -d \
      -p 9100:9100 \
      --name node-exporter \
      -v "/proc:/host/proc" \
      -v "/sys:/host/sys" \
      -v "/:/rootfs" \
      --net="host" \
      quay.io/prometheus/node-exporter \
        -collector.procfs /host/proc \
        -collector.sysfs /host/sys \
        -collector.filesystem.ignored-mount-points "^/(sys|proc|dev|host|etc)($|/)"

### mysqld\_exporter ###

#配置授权
    mysql> CREATE USER 'mysql_monitor'@'localhost' IDENTIFIED BY 'mysql_monitor' WITH MAX_USER_CONNECTIONS 3;
    mysql> GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'mysql_monitor'@'localhost';
    mysql> FLUSH PRIVILEGES;
    #运行
    docker run -d \
     -p 9104:9104 \
     -e DATA_SOURCE_NAME="mysql_monitor:mysql_monitor@(10.10.0.186:3306)/" prom/mysqld-exporter

### redis\_exporter ###

#下载镜像
    docker pull oliver006/redis_exporter
    #运行
    docker run -d \
    --name redis_exporter \
    -p 9121:9121 \
    oliver006/redis_exporter --redis.addr redis://192.168.10.208:6379

###  ###

## Prometheus ##

### 创建配置文件 ###

\#创建目录并授权  
sudo mkdir /usr/local/src/file/prometheus  
sudo chown 767 /usr/local/src/file/prometheus  
\#编写配置文件  
prometheus.yml，并存放到/usr/local/src/file/prometheus目录下

# my global config
    global:   # 全局设置，可以被覆盖
      scrape_interval:     15s # 默认值为 15s，用于设置每次数据收集的间隔
      evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
      # scrape_timeout is set to the global default (10s).
    
    # 告警管理配置
    alerting:
      alertmanagers:
      - static_configs:
        - targets:
          # - alertmanager:9093
    
    # Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
    rule_files:
      # - "first_rules.yml"
      # - "second_rules.yml"
    
    # A scrape configuration containing exactly one endpoint to scrape:
    # Here it's Prometheus itself.
    scrape_configs:
      # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
      - job_name: 'prometheus'  # 采集 Prometheus 自身的 metrics
    
        # metrics_path defaults to '/metrics'
        # scheme defaults to 'http'.
    
        static_configs:
        - targets: ['localhost:9090']  # Prometheus的endpoint
    
      - job_name: 'redis'
        static_configs:
         - targets: ['192.168.142.130:9121']  # Prometheus会定期请求这个网址，来获取你想记录的数据
           labels:
             instance: redis
    
      - job_name: 'linux'
        static_configs:
         - targets: ['192.168.142.130:9100']  # node_exporter 的 endpoint
           labels:
             instance: node
      - job_name: mysql
    	  static_configs:
    	    - targets: ['10.10.0.186:9104']
    	      labels:
    	        instance: mysql

### 安装Prometheus ###

#下载镜像
    docker pull prom/prometheus
    #运行
    sudo docker run -d \
      -p 9090:9090 \
      -v /usr/local/src/file/prometheus.yml:/usr/local/src/file/prometheus/prometheus.yml \
      quay.io/prometheus/prometheus \
      --config.file=/usr/local/src/file/prometheus/prometheus.yml
