一、前言

Apache SkyWalking 是一个开源的分布式跟踪、监控和诊断系统，旨在帮助用户监控和诊断分布式应用程序、微服务架构和云原生应用的性能和健康状况。它提供了可视化的分析工具，帮助开发人员和运维团队深入了解应用程序的性能、调用链和异常情况

功能特点

分布式跟踪： SkyWalking 能够追踪分布式应用程序的请求调用链，显示每个请求从发起到结束的完整流程，包括各个组件和服务之间的调用关系。这有助于定位性能瓶颈和延迟问题

性能监控： SkyWalking 收集并展示应用程序的性能指标，如响应时间、吞吐量、错误率等，以图表和图形的形式呈现，帮助用户监控应用程序的健康状况

实时告警： SkyWalking 具备实时告警功能，可以根据用户定义的条件和阈值生成警报。当应用程序出现性能问题或异常时，系统会发送通知，让团队能够及时采取行动

多语言支持： SkyWalking 支持多种编程语言和技术栈，包括 Java、Python、Go、.NET 等。这使得它适用于各种类型的应用程序

可视化界面： SkyWalking 提供了直观的 Web 界面，用户可以通过图表、仪表盘和可视化的调用链图来查看和分析应用程序的性能数据

二、部署

部署skywalking之前需要先部署java环境，我用的是skywalking的9.4.0版本，所有需要使用jdk11本版的java环境

部署java参考：jdk1.8环境配置_Apex Predator的博客-CSDN博客

部署skywalking服务，需要先下载安装包，我这边使用的是9.4.0版本

下载路径参考：Downloads | Apache SkyWalking

创建skywalking存放目录并将安装包放到该目录下解压

mkdir /opt/skywalking && cd /opt/skywalking

tar -zxvf apache-skywalking-apm-9.4.0.tar.gz && mv apache-skywalking-apm-9.4.0 skywalking

编辑skywalking配置文件，主要是配置数据存放的选择，默认使用自带的h2存储，我们这边改成使用elasticsearch作为存储

vi skywalking/config/application.yml

配置skywalking web服务

vi skywalking/webapp/application.yml

serverPort: ${SW_SERVER_PORT:-18080}    #默认端口为8080，避免冲突改为18080# Comma seperated list of OAP addresses.
oapServices: ${SW_OAP_ADDRESS:-http://localhost:12800}  #这些配置保持默认即可zipkinServices: ${SW_ZIPKIN_ADDRESS:-http://localhost:9412}

启动skywalking服务

./skywalking/bin/startup.sh
