启动skywalking

解压压缩包，进入bin目录：C:\05components\apache-skywalking-apm-6.6.0\apache-skywalking-apm-bin\bin

双击startup.bat启动

显示如上说明启动成功，也可以在logs查看日志
cd C:\05components\apache-skywalking-apm-6.6.0\apache-skywalking-apm-bin\logs\skywalking-oap-server.log
可以看到监听11800，12800，8080端口
启动成功后会启动两个服务，一个是skywalking-oap-server，一个是skywalking-web-ui：8080
skywalking-oap-server服务启动会暴露11800和12800两个端口，分别为收集监控数据的端口11800和接受前端请求的端口12800，修改端口可以修改config/application.yml

访问 127.0.0.1:8080

Tomcat接入

方法1：修改Tomcat7w.exe中java参数

加入如下参数

-javaagent:C:\05components\apache-skywalking-apm-6.6.0\apache-skywalking-apm-bin\agent\skywalking-agent.jar
-Dskywalking.agent.service_name=sgb-test
-Dskywalking.collector.backend_service=localhost:11800

方法2：修改catalina.bat

在首行加入如下信息

• Linux Tomcat 7-9

修改 tomcat/bin/catalina.sh 的第一行：

CATALINA_OPTS="$CATALINA_OPTS -javaagent:/opt/agent/skywalking-agent.jar"; export CATALINA_OPTS
1
2

• Windows Tomcat 7-9
  修改 tomcat/bin/catalina.bat 的第一行：

set "CATALINA_OPTS=-javaagent:/opt/agent/skywalking-agent.jar"
1

方法3：修改catalina.bat

添加内容：

• 单个项目：

set "CATALINA_OPTS= -javaagent:D:\Tools\apache-skywalking-apm-8.7.0\agent\skywalking-agent.jar -Dskywalking.agent.service_name=demo -Dskywalking.collector.backend_service=localhost:11800"
1

• 多个项目：

set JAVA_OPTS=-javaagent:D:\Tools\apache-skywalking-apm-8.7.0\agent\skywalking-agent.jar=agent.service_name=test1,agent.service_name=test2
1

或者

set "CATALINA_OPTS= -javaagent:D:\Tools\apache-skywalking-apm-8.7.0\agent\skywalking-agent.jar=agent.service_name=test1,agent.service_name=test2"
