Does pm2 auto restart application after reboot by default?

I have an issue with my linux server and need to reboot, before that I run my node application with `pm2 start server.js` without any other config. Can it auto restart my app after reboot server?

Not by default, but PM2 can do so using a [startup script](

After generating your startup script (read also this [comment](

)), take a look at `pm2 save`:

You can use this script before run `pm2 save`:

pm2 startup
[PM2] You have to run this command as root. Execute the following command:
sudo su -c "env PATH=$PATH:/home/unitech/.nvm/versions/node/v14.3/bin pm2 startup <distribution> -u <user> --hp <home-path>

**First of all I run below command**

`pm2 save`

Then edit **crontab**

nano /etc/crontab

**Then Add**

* * * * * pm2 resurrect

No, if you do not add a startup command then it will close after reboot so

you can use:
```bash
pm2 startup ubuntu
```

After this, it's always run after closing the server in the terminal.

I used another alternative way on Ubuntu 20.04 and it worked!

Make sure you have saved the pm2 configuration (**pm2 save**)

**First edit the crontab file**

```
crontab -e
```
**Then paste the following command**
```
@reboot /usr/lib/node_modules/pm2/bin/pm2 resurrect && /usr/lib/node_modules/pm2/bin/pm2 start all
```
