 # -----------------------------------------------------------------------------
 CATALINA_OPTS="$CATALINA_OPTS -javaagent:/data/skywalking-agent/skywalking-agent.jar"; export CATALINA_OPTS
 配置skywalking-agent参数：
 agent.service_name=${SW_AGENT_NAME:magedu}
 agent.namespace=${SW_AGENT_NAMESPACE:jenkins}
 collector.backend_service=${SW_AGENT_COLLECTOR_BACKEND_SERVICES:172.31.2.161:11800} 上传Jenkins app并启动tomcat：
 root@skywalking-agent1:/apps# ls /apps/apache-tomcat-8.5.84/webapps/
 ROOT docs examples host-manager jenkins.war manager
 root@skywalking-agent1:/apps# /apps/apache-tomcat-8.5.84/bin/catalina.sh run

 添加主机名解析，dubbo里面的zookeeper地址写在了源代码中，域名变量为ZK_SERVER1：
 root@skywalking-node1:~# vim /etc/profile
 export ZK_SERVER1=172.31.2.163
 root@skywalking-node1:~# source /etc/profile
 root@skywalking-node1:~# echo $ZK_SERVER1
