# 监控安装文档

# 1、 `prometheus`

1. 上传`prometheus`安装包至`lab3`服务器`/opt/modules/`目录下并解压

   ```shell
   tar -zxf prometheus-2.32.1.linux-amd64.tar.gz
   ```

2. 进入`/opt/modules/prometheus-2.32.1`目录，修改`prometheus.yml`文件

   ```shell
   vi prometheus.yml
   ```

   将配置信息做如下修改

   ```shell
   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: ["lab3:9090"]
     - job_name: "node exporter"
   
       # metrics_path defaults to '/metrics'
       # scheme defaults to 'http'.
   
       static_configs:
         - targets: ['lab1:8100', 'lab2:8100', 'lab3:8100']
     - job_name: "kafka exporter"
   
       # metrics_path defaults to '/metrics'
       # scheme defaults to 'http'.
   
       static_configs:
         - targets: ['lab3:9308']
   ```

3. 在`/opt/modules/prometheus-2.32.1`目录下启动`prometheus`

   ```shell
   nohup ./prometheus --config.file=prometheus.yml > ./prometheus.log 2>&1 &
   ```

4. 查看`9090`端口状态或浏览器访问`http://lab3:9090`验证是否成功

   ```shell
   lsof -i:9090
   ```

# 2、`node_exporter`

1. 上传`node_exporter`安装包至`lab3`服务器`/opt/modules/`目录下并解压

   ```shell
   tar -zxf node_exporter-1.3.1.linux-amd64.tar.gz
   ```

2. 进入`/opt/modules/node_exporter-1.3.1`目录，启动`node_exporter`

   ```shell
   nohup ./node_exporter --web.listen-address=:8100 &
   ```

3. 查看`8100`端口状态或浏览器访问`http://lab3:8100/metrics`验证是否成功

   ```shell
   lsof -i:8100
   ```

4. 在`lab1`和`lab2`上重复上述步骤

# 3、 `kafka_exporter`

1. 上传`kafka_exporter`安装包至`lab3`服务器`/opt/modules/`目录下并解压

   ```shell
   tar -zxf kafka_exporter-1.4.2.linux-amd64.tar.gz
   ```

2. 进入`/opt/modules/kafka_exporter-1.4.2`目录，启动`kafka_exporter`

   ```shell
   nohup ./kafka_exporter --kafka.server=lab3:9092 > kafka_exporter.log  --web.listen-address=:9308 &
   ```

3. 查看`9308`端口状态或浏览器访问`http://lab3:9308/metrics`验证是否成功

   ```shell
   lsof -i:9308
   ```

# 4、`grafana`

1. 上传`grafana`至`lab3`服务器`/opt/modules/`目录

2. 进入`/opt/modules/grafana-8.3.4`目录，启动`grafana`

   ```shell
   nohup ./bin/grafana-server web > ./grafana.log 2>&1 &
   ```

3. 查看`3000`端口状态或浏览器访问`http://lab3:3000/`验证是否成功

   ```shell
   lsof -i:3000
   ```

4. 访问`http://lab3:3000`， 用户和密码均为`admin`
5. 进入左侧设置，配置`prometheus`数据源及`mysql`数据源
