Server process run through command do not persist in my Amazon Lightsail Instance

Question

I created an Amazon Lightsail Instance of 512MB RAM,

I have got all my production server files installed on my Amazon Lightsail Instance. Then I connected to the instance via SSH.
Then I ran my database command in the background via the browser SSH window:

```
mongod --dbpath=data &
```

Then I ran my server command in the background:

```
next start -H  -p 
```

Then I closed the browser ssh window. Then, after some time I found that the server was not able to be reached via the url.
It was working when I had the ssh window open.

I opened the ssh window again, and did `ps` to see if the processes were still running. I found that both the database process and the server process were closed.

I want them to persist forever, i.e. the processes shouldn't close because I want to use my website at any time right.

Answer

Try this, after you start the process:
1. ctrl+ z
2. bg
3. disown -h or disown -a
Basically running the process as background.

There are options tmux, nohup, screen, byobu.
PS: I am a beginner and I got this info after a bit of googling. I hope it helps. Please ignore if it doesn't or if you know this already
