drwxr-xr-x. 2 root root       26 Oct 27 23:15 projectC
drwxr-xr-x. 2 root root       26 Oct 27 23:15 projectD

3，启动
bin/startup.sh
4，查看进程已启动

[root@localhost live-demo]# jps
2336 projectA.jar
1634 QuorumPeerMain
1956 Kafka
1957 eureka-service.jar
2742 Jps
1481 OAPServerStartUp
2282 projectB.jar
1500 skywalking-webapp.jar
2301 projectC.jar
2318 projectD.jar

六，测试访问

[root@localhost live-demo]# curl http://localhost:8764/projectA/test
{"traceId":"373cbdbaae8547339134046c5dc5f57b.45.16038859660730001"}[root@localhost live-demo]# 
[root@localhost live-demo]# curl http://localhost:8764/projectA/test
{"traceId":"373cbdbaae8547339134046c5dc5f57b.48.16038861251250001"}
