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

### 查看 port 
輸入 `netstat -lntp`
```log

 will not be shown, you would have to be root to see it all.)

### 嘗試 kill pid 失敗
```log
ubuntu@ip-172-31-38-203:/var/www/hati8haha.tw/hati8haha.tw$ lsof -i :5001
COMMAND     PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
node\x20/ 17998 ubuntu   20u  IPv6  79493      0t0  TCP *:5001 (LISTEN)
ubuntu@ip-172-31-38-203:/var/www/hati8haha.tw/hati8haha.tw$ sudo kill -9 17998
ubuntu@ip-172-31-38-203:/var/www/hati8haha.tw/hati8haha.tw$ lsof -i :5001
COMMAND     PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

```

### 可能解決方法
[參考自進度報告 8/10 ](https://learning.lidemy.com/users/201)
>同學遇到的 node 佔用 port 的問題今天我也遇到了，因為寫註冊資料感覺有成功但是 iTerm 上又沒有任何訊息跑出來，所以懷疑是 port 的問題。
解決方法用 kill PID 是殺不掉的，要用 killall -9 node ，stackoverflow 又再一次順利地解決我的問題＾＾

```

### 解決方法
不要用 ` sudo apt install npm`

用 `curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -
sudo apt-get install -y nodejs` 安裝
