**二、配置文件**

在解压后的根目录下，新建loki-local-config.yaml配置文件，内容如下：

auth_enabled: false
    
    server: 
       http_listen_port: 3100
    
    ingester: 
      lifecycler: 
        address: 127.0.0.1
        ring:
          kvstore: 
            store: inmemory
          replication_factor: 1
        final_sleep: 0s
      chunk_idle_period: 5m
      chunk_retain_period: 30s
      max_transfer_retries: 0
    
    schema_config: 
      configs: 
        - from: 2022-02-15
          store: boltdb
          object_store: filesystem
          schema: v11
          index: 
            prefix: index_
            period: 168h
    
    storage_config: 
      boltdb: 
        directory: /tmp/loki/index
    
      filesystem: 
        directory: /tmp/loki/chunks
    
    limits_config: 
      enforce_metric_name: false
      reject_old_samples: true
      reject_old_samples_max_age: 168h
    
    chunk_store_config: 
      max_look_back_period: 0s
    
    table_manager: 
      retention_deletes_enabled: false
      retention_period: 0s

新增promtail-local-config.yaml配置文件，内容如下：

server: 
      http_listen_port: 9080
      grpc_listen_port: 0
    
    positions: 
      filename: /tmp/positions.yaml
    
    clients: 
      - url: http://127.0.0.1:3100/loki/api/v1/push
    
    scrape_configs: 
    - job_name: system
      static_configs: 
      - targets:
          - 127.0.0.1
        labels: 
          job: testlogs
    #第1个监控日志目录
          __path__: C:\Users\Administrator\Desktop\fsdownload\*.log
    - job_name: system1
      static_configs: 
      - targets:
          - 127.0.0.1
        labels: 
    #第2个监控日志目录
          job: alogs
          __path__: D:\work\product\MES\windows-pro\logs\*.log

**三、创建启动脚本**

在根目录下新增loki的启动的windows命令行脚本，内容如下：

.\loki-windows-amd64.exe --config.file=loki-local-config.yaml

在根目录下新增promtail的启动的windows命令行脚本，内容如下：

.\promtail-windows-amd64.exe --config.file=promtail-local-config.yaml

**四、配置loki**

安装好Grafana后，先启动上面的loki服务，后启动promtail服务，浏览器访问grafana，地址：[http://127.0.0.1:3000/][http_127.0.0.1_3000]

点击左下角的设置图标，选择Configuration![de5ea8c5b2e04851a74a511b3bc1dcb5.png][]

Add Data source，选择loki

![9995f4bd20d34b70874da4435353f3f7.png][]

输入loki的URL，默认就是http://127.0.0.1:3100

![7ffd078be61c4740a3df12643ed28c39.png][]

点击下面的Save&test,若提示“Data source connected, but no labels received. Verify that Loki and Promtail is configured properly.”，检查上面配置的promtail-local-config.yaml中的“\_path\_”路径是否存在，若test成功，则会有如下测试：

**五、验证效果**

点击左侧工具栏，选择Explore

选择要查询的日志标签，然后输入要搜索的日志文本内容，点击回国或右上角的“Run query”，

1.64G的日志文件，秒极返回查询结果
