Getting Started with Skywalking

Pre

• JDK 1.8+
• Skywalking(v3.2.6) (All packages can be download from GitHub):
  • skywalking-web.tar.gz
  • skywalking-collector.tar.gz
  • skywalking-agent.tar.gz
• ElasticSearch (ver 5.3.0)

Install

Directly decompress above tar packages.

Settings

There is a folder, read config, under each model which contain several setting files of skywalking. The default settings can cover plenty of use cases, so you can ignore these settings file and just start up the application. If you install skywalking on a server which already running a web-server on it, the default http ports(80, 443, 8080, 8443) might been bind to another application. In this case, you should consider adjust the port of embedded jetty. The main steps are as follow:

• Switch to skywalking-web installation folder.
• Jump into config folder.
• Edit server.port property to re-target web server's port in application.properties.

Start Service

All components of skywalking run on stand-alone JVM processes, in other words, each service can be started separately without order. Though skywalking give the maximum degree of freedom to the user, I still strongly recommend you consider the following procedure:

• Start ElasticSearch;
• Start skywalking-collector;
• Start skywalking-web
• Start your application with skywalking-agent.
  • For SpringBoot application, one should laungh jar file as follow:

    java -jar -javaagent:/<Path>/skywalking-agent/skywalking-agent.jar \
    
    ./APPLICATION.jar

  • In case, application been deployed via stander webserver, Tomcat for instance, one should consider attach -javaagent:/<Path>/skywalking-agent/skywalking-agent.jar commend to the start script.
