集群配置说明

  • 集群模式- 基于nacos
  • 动态配置发布- 基于nacos
  • 存储- 基于elasticsearch7

nacos配置参照nacos部署

es配置参照ELK部署

创建配置目录

mkdir -pv /data/skywalking/{config,data}

  • 1

加载配置文件方式部署

docker-compose编排

mkdir -pv /data/docker-compose/skywalking
cat > /data/docker-compose/skywalking/docker-compose.yml << EOF
version: "3"
services:
  oap:
    container_name: sw-oap

    restart: always
    network_mode: host
    volumes:
      - /etc/localtime:/etc/localtime
      - /data/skywalking/data:/root
#      - /data/skywalking/config/application.yml:/skywalking/config/application.yml

    deploy:

        reservations:

    restart: always
    volumes:

    depends_on:
      - oap
    environment:

      SW_OAP_ADDRESS: 3.1.101.39:12800
    deploy:

先启动生成容器一次,拷贝出配置文件,进行修改

docker-compose up -d
docker cp sw-oap:/skywalking/config/application.yml /data/skywalking/config/

修改配置

修改内容如下

cluster:
  selector: ${SW_CLUSTER:nacos}
  nacos:
    serviceName: ${SW_SERVICE_NAME:"SkyWalking_OAP_Cluster"}
    hostPort: ${SW_CLUSTER_NACOS_HOST_PORT:3.1.101.45:8848}
    namespace: ${SW_CLUSTER_NACOS_NAMESPACE:"skywalking"}
    username: ${SW_CLUSTER_NACOS_USERNAME:"nacos"}
    password: ${SW_CLUSTER_NACOS_PASSWORD:"nacos"}
    
storage:
  selector: ${SW_STORAGE:elasticsearch7}
  elasticsearch7:
    clusterNodes: ${SW_STORAGE_ES_CLUSTER_NODES:3.1.101.33:9200,3.1.101.34:9200,3.1.101.35:9200}
    
core:
  selector: ${SW_CORE:default}
  default:
    restHost: ${SW_CORE_REST_HOST:3.1.101.39}
    restPort: ${SW_CORE_REST_PORT:12800}
    gRPCHost: ${SW_CORE_GRPC_HOST:3.1.101.39}
    gRPCPort: ${SW_CORE_GRPC_PORT:11800}
   
configuration:
  selector: ${SW_CONFIGURATION:nacos}
  nacos:
    serverAddr: ${SW_CONFIG_NACOS_SERVER_ADDR:3.1.101.45}
    port: ${SW_CONFIG_NACOS_SERVER_PORT:8848}
    group: ${SW_CONFIG_NACOS_SERVER_GROUP:skywalking}
    namespace: ${SW_CONFIG_NACOS_SERVER_NAMESPACE:skywalking}
    username: ${SW_CONFIG_NACOS_USERNAME:"nacos"}
    password: ${SW_CONFIG_NACOS_PASSWORD:"nacos"}

取消docker-compose.yml注销的配置文件行, 并重启生成skywalking容器

docker-compose up -d

nacos创建命名空间的ID要为skywalking

Docker变量方式部署

  • 参照application.yml配置文件, 配置中的大写值在容器中都可以作为环境变量引用到服务, 所有只需要将参数通过docker变量传入即可
mkdir -pv /data/docker-compose/skywalking
cat > /data/docker-compose/skywalking/docker-compose.yml << EOF
version: "3"

  oap:
    container_name: sw-oap

    volumes:
      - /etc/localtime:/etc/localtime
      - /data/skywalking/data:/root
