• ES安装，存储skywalking数据时用

　　1、将下载文件解压至安装磁盘，并修改配置文件

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
bootstrap.memory_lock: true

#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
network.host: 127.0.0.1

#跨域配置

http.cors.enabled: true
http.cors.allow-origin: "*"

#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
http.port: 9200

ingest.geoip.downloader.enabled: false
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
#
# ---------------------------------- Security ----------------------------------
#
#                                 *** WARNING ***
#
# Elasticsearch security features are not enabled by default.
# These features are free, but require configuration changes to enable them.
# This means that users don’t have to provide credentials and can get full access
# to the cluster. Network connections are also not encrypted.
#
# To protect your data, we strongly encourage you to enable the Elasticsearch security features. 
# Refer to the following documentation for instructions.
#
# https://www.elastic.co/guide/en/elasticsearch/reference/7.16/configuring-stack-security.html

　　

network.host: 127.0.0.12、
2、如果你希望Elasticsearch在所有可用的网络上监听，可以设置为0.0.0.0。如果你只想在localhost上监听，可以设置为127.0.0.1

如果本机监听，配置不0.0.0.0,则ES启动报错

　3、进入bin子目录进行安装，注意需要以管理员权限运行

elasticsearch-service.bat install

　4、安装完成后，可以用命令启动，也可以在服务列表手动启动

elasticsearch-service.bat start

　　

• skywalking安装

 　　1、将下载文件解压至安装磁盘，如D:

 　　2、主要改两个配置，默认为h2存储， 我用的时ES

storage:
  selector: ${SW_STORAGE:elasticsearch}
  elasticsearch:
    namespace: ${SW_NAMESPACE:"my-application"}

　　

　　3、配置完成后，先启动ES，等待ES启动成功后，再启动skywalking

 

 

• net6 中实际操作

1. 　　添加依赖包

 

　　2、生成skyapm.json文件

　　安装工具

dotnet tool install -g SkyAPM.DotNet.CLI

　　生成配置

dotnet tool install -g SkyAPM.DotNet.CLI

　　

　　注意：这个skyapm.json文件，尽量用这种方式生成，我之前是网上copy的，有个地方有细微差别，导致监控不到追踪记录

{
  "SkyWalking": {
    "ServiceName": "user-skywalking",
    "Namespace": "",
    "HeaderVersions": [
      "sw8"
    ],
    "Sampling": {
      "SamplePer3Secs": -1,
      "Percentage": -1.0
    },
    "Logging": {
      "Level": "Information",
      "FilePath": "logs\\skyapm-{Date}.log"
    },
    "Transport": {
      "Interval": 3000,
      "ProtocolVersion": "v8",
      "QueueSize": 30000,
      "BatchSize": 3000,
      "gRPC": {
        "Servers": "127.0.0.1:11800",
        "Timeout": 10000,
        "ConnectTimeout": 10000,
        "ReportTimeout": 600000,
        "Authentication": ""
      }
    }
  }
}

　　

　　3、修改环境变量launchSettings.json，添加配置

   "ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "SkyAPM.Agent.AspNetCore",
   "SKYWALKING__SERVICENAME": "user-skywalking",

　　

{
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "profiles": {
    "UserService_Skywalking": {
      "commandName": "Project",
      "dotnetRunMessages": true,
      "launchBrowser": true,
      "launchUrl": "swagger",
      "applicationUrl": "http://localhost:5001",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development",
        "ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "SkyAPM.Agent.AspNetCore",
        "SKYWALKING__SERVICENAME": "user-skywalking",
        "SKYWALKING__TRANSPORT__GRPC__SERVERS": "localhost:11800",
        "SKYWALKING__SERVICEENDPOINT": "http://localhost:12800"
      }
    }
  }
}

　　

注意：user-skywalking名称与skyapm.json中的ServiceName要一致

 

• 运行net6项目，实际测试某个接口，在skywalking中查看日志和追踪记录
