AWS EC2 nginx + pm2 部署踩雷紀錄 === ###### tags: `部署` ## port 22: Connection refused 重啟 instance 後無法連線 ` ssh -i "mykey.pem" ubuntu@ec2-3-144-77-50.us-east-2.compute.amazonaws.com` => 拿掉雙引號 ` ssh -i mykey.pem ubuntu@ec2-3-144-77-50.us-east-2.compute.amazonaws.com` ## pm2 任務無法執行 ### 查看 log `sudo pm2 log` ```log ubuntu@ip-172-31-38-203:/var/www/hati8haha.tw/hati8haha.tw$ sudo pm2 log 0 [TAILING] Tailing last 15 lines for [0] process (change the value with --lines option) /root/.pm2/logs/index-out.log last 15 lines: 0|index | Example app listening on port 5001! 0|index | Example app listening on port 5001! 0|index | Example app listening on port 5001! 0|index | Example app listening on port 5001! 0|index | Example app listening on port 5001! /root/.pm2/logs/index-error.log last 15 lines: 0|index | at listenInCluster (node:net:1363:12) 0|index | at Server.listen (node:net:1450:7) 0|index | at Function.listen (/var/www/hati8haha.tw/hati8haha.tw/node_modules/express/lib/application.js:61 0|index | at Object.<anonymous> (/var/www/hati8haha.tw/hati8haha.tw/index.js:52:5) 0|index | at Module._compile (node:internal/modules/cjs/loader:1101:14) 0|index | at Object.Module._extensions..js (node:internal/modules/cjs/loader:1153:10) 0|index | at Module.load (node:internal/modules/cjs/loader:981:32) 0|index | at Function.Module._load (node:internal/modules/cjs/loader:822:12) 0|index | at Object.<anonymous> (/usr/lib/node_modules/pm2/lib/ProcessContainerFork.js:33:23) { 0|index | code: 'EADDRINUSE', 0|index | errno: -98, 0|index | syscall: 'listen', 0|index | address: '::', 0|index | port: 5001 0|index | } ``` ### 查看 port 輸入 `netstat -lntp` ```log (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.)
