.netcore3.1使用skywalking8.1.0(docker-compose一键部署)

1、安装Skywalking环境

这里我使用的是docker-compose一键安装的方式，docker-compose有三种方式可安装：

(我选择的是第二种方式安装)

1.1>参见官网：https://docs.docker.com/compose/install/

 

1.1.1>下载docker compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

1.1.2>添加可执行权限

sudo chmod +x /usr/local/bin/docker-compose

1.1.3>将文件copy到 /usr/bin/目录下

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

1.1.4>查看版本

docker-compose –version

 

1.2>通过pip进行安装

1.2.1>安装pip

yum -y install epel-release
yum -y install python-pip

查看版本

pip –version

1.2.2>更新pip

pip install --upgrade pip

1.2.3>安装docker-compose

pip install docker-compose

1.2.4>查看docker compose的版本

docker-compose version

1.3>离线安装

访问https://github.com/docker/compose/releases，下载 docker-compose-Linux-x86_64，将docker-compose-Linux-x86_64重命名为docker-compose

通过ssh工具MobaXterm，将刚才下载的docker-compose文件上传到centos7的/usr/local/bin/目录下

输入以下命令 添加可执行权限和查看docker compose版本：

# 添加可执行权限
sudo chmod +x /usr/local/bin/docker-compose
# 查看docker-compose版本
docker-compose -v

 

2、一键部署skywalking

2.1>创建文件夹skywalking，并切换到该目录下：

mkdir skywalking
cd skywalking

2.2>创建文件docker-compose.yml，写入内容：

内容参见：https://github.com/apache/skywalking-docker/blob/master/8/8.1.0/compose-es7/docker-compose.yml，直接用即可，可视具体情况修改参数

vi docker-compose.yml

version: '3.8'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.0
    container_name: elasticsearch
    restart: always
    ports:
      - 9200:9200
    healthcheck:
      test: ["CMD-SHELL", "curl --silent --fail localhost:9200/_cluster/health || exit 1"]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 40s
    environment:
      - discovery.type=single-node
      - bootstrap.memory_lock=true

  oap:

    links:
      - elasticsearch
    restart: always
    ports:

      - 12800:12800
    healthcheck:
      test: ["CMD-SHELL", "/skywalking/bin/swctl"]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 40s
    environment:
      SW_STORAGE: elasticsearch7
      SW_STORAGE_ES_CLUSTER_NODES: elasticsearch:9200
  ui:
    image: apache/skywalking-ui:8.1.0
    container_name: ui
    depends_on:
      - oap
    links:
      - oap
    restart: always
    ports:
      - 8080:8080
    environment:
      SW_OAP_ADDRESS: oap:12800

Insert切换插入模式；按Esc，输入:wq，保存并退出vi编辑

2.3>执行docker-compose.yml

docker-compose up -d

(偶尔可能会因为网络原因失败，重新执行命令即可)

2.4>skywalking部署完成之后，可正常访问：es和ui(IP地址根据实际情况输入)

http://192.168.56.10:9200/

http://192.168.56.10:8080/

正常打开无报错信息即可

 

3、.NetCore使用SkyWalking(已创建好WebAPI工程)

3.1>引用包SkyAPM.Agent.AspNetCore，记得为1.0.0版本；

在根目录创建skyapm.json文件，并设置复制到输出目录：如果较新则复制

写入内容：

{
  "SkyWalking": {
    "ServiceInstanceName": "OpenServiceInstance",
    "ServiceName": "OpenService",
    "Logging": {
      "Level": "Information",
      "FilePath": "logs\skyapm-{Date}.log"
    },
    "Transport": {
      "Interval": 3000,
      "QueueSize": 30000,
      "BatchSize": 3000,
      "gRPC": {
        "Servers": "192.168.56.10:11800",
        "Timeout": 10000,
        "ConnectTimeout": 10000,
        "ReportTimeout": 600000
      }
    }
  }
}

ServiceName为服务名称，ServiceInstanceName为实例名称，Servers为skywalking收集器地址，只需要改动该三项即可

3.2> 配置启动环境变量

在launchSettings.json中增加环境变量配置：

"ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "SkyAPM.Agent.AspNetCore"

运行起来并任意访问一个api地址，然后在skywalking-ui中可追溯api访问记录：

(时间范围记得根据实际情况选择)

 

大功告成
