Environment
Software Version:
需要注意的
- 官网：http://skywalking.apache.org/
- 如果端口8080,10800,11800,12800不被占用，你可以直接解压tar / unzip,然后启动，不需要更改冲突的端口号。
- apache-skywalking-apm 对版本要求比较严格，还有各个版本的配置变化可能比较大。
- ES服务需要设置name和cluster_name，注意监听地址
- ui界面的同步，每个人测试环境的性能和测试软件的不同，刷新数据的时间可能会有不同。
Install
前提
jdk es 安装好，配置好
jdk验证

检查日志，在根目录的logs下

Agent set
官方步骤 ：https://github.com/apache/skywalking/blob/5.x/docs/cn/Deploy-skywalking-agent-CN.md
java mvc demo
下载示例代码
$ mkdir -p /opt/mvc-demo && cd /opt/mvc-demo && wget https://github.com/lijinghuatongxue/Blog_Example/blob/master/skywalking-apm/sprintbootdemo-0.0.1-SNAPSHOT.jar
拷贝 apache-skywalking-apm-bin 目录下面的 agent目录到我们测试的代码根目录下
agent配置好的话，命令行则不需要再写
$ cp -rf apache-skywalking-apm-bin/agent /opt/mvc-demo
$ vim /opt/mvc-demo/agent/config/agent.config
···
agent.service_name=${SW_AGENT_NAME:java-test}
collector.backend_service=${SW_AGENT_COLLECTOR_BACKEND_SERVICES:192.168.0.253:11800} # 这里是我们远程server的地址
···
$ java -javaagent:/opt/mvc-demo/agent/skywalking-agent.jar -Dserver.port=9999 -jar sprintbootdemo-0.0.1-SNAPSHOT.jar

jenkins demo
按上面同样的方法把agent目录复制到 /opt/jenkins下面，但是需要更改配置
$ mkdir -p /opt/jenkins-demo && cd /opt/jenkins-demo && wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war
$ $ vim /opt/jenkins-demo/agent/config/agent.config
···
agent.service_name=${SW_AGENT_NAME:jenkins-test}
collector.backend_service=${SW_AGENT_COLLECTOR_BACKEND_SERVICES:192.168.0.253:11800} # 这里是我们远程server的地址
···
启动
$ java -javaagent:/opt/jenkins-demo/agent/skywalking-agent.jar -Dhudson.util.ProcessTree.disable=true -jar /opt/jenkins-demo/jenkins.war --httpPort=8888
然后按照以往的配置去配置完jenkins，耐心等待一会，然后去skywalking控制台去查看。
Demo
当然，可玩性很高，祝你路途愉快
