Loki 的安装和配置

Docker Compose 方式

1. 创建相关目录

mkdir -p /apps/loki/conf

2. 编辑 docker-compose.yml 文件

vim /apps/loki/docker-compose.yml

version: "3"
services:
  loki:
    image: grafana/loki:2.6.1
    container_name: prometheus-loki
    hostname: loki
    restart: always
    volumes:
      - /apps/loki/conf/loki-config.yaml:/etc/loki/loki-config.yaml
    ports:
      - 3100:3100
    command: "-config.file=/etc/loki/loki-config.yaml"
networks:
  default:
    external:
      name: prometheus

3. 编辑 loki-config.yaml 文件

vim /apps/loki/conf/loki-config.yaml

auth_enabled: false

server:
  http_listen_port: 3100
  grpc_listen_port: 9096

common:
  path_prefix: /tmp/loki
  storage:
    filesystem:
      chunks_directory: /tmp/loki/chunks
      rules_directory: /tmp/loki/rules
  replication_factor: 1
  ring:
    instance_addr: 127.0.0.1
    kvstore:
      store: inmemory

schema_config:
  configs:

      store: boltdb-shipper
      object_store: filesystem
      schema: v11

# By default, Loki will send anonymous, but uniquely-identifiable usage and configuration
# analytics to Grafana Labs. These statistics are sent to https://stats.grafana.org/
#
# Statistics help us better understand how Loki is used, and they show us performance
# levels for most users. This helps us prioritize features and documentation.
# For more information on what's sent, look at
# https://github.com/grafana/loki/blob/main/pkg/usagestats/stats.go
# Refer to the buildReport method to see what goes into a report.
#
# If you would like to disable reporting, uncomment the following lines:
#analytics:
#  reporting_enabled: false

4. 配置 docker 网段 prometheus
   检查是否存在 prometheus 网段：

docker network list

若不存在，则创建：

docker network create prometheus --subnet 10.21.22.0/24

5. 启动 Loki 容器

cd /apps/loki

docker-compose up -d

6. 检查 Loki 容器状态、查看 Loki 容器日志

cd /apps/loki

docker-compose ps

docker-compose logs -f
