# 1、查看服务
[root@vm172-20-169-183 ~]# ps -ef |grep node
root      1473  1019  0 14:02 pts/0    00:00:00 grep --color=auto node
root     23859     1  0 13:28 ?        00:00:03 node /opt/server/node_modules/egg-scripts/lib/start-cluster "title":"chickenfarm-server","baseDir":"/opt/server","framework":"/opt/server/node_modules/egg" --title=chickenfarm-server
root     23962 23859  0 13:28 ?        00:00:02 /opt/node/bin/node /opt/server/node_modules/egg-cluster/lib/agent_worker.js 

# 2、查看端口
