pm2

I want to install pm2...but get a permission denied error. Any restrictions i need to be aware off? Many thanks

You can install pm2 like so:

mkdir -p ~/opt/pm2
cd ~/opt/pm2
npm install pm2
ln -s node_modules/.bin bin

When that's done you can run it like: ~/opt/pm2/bin/pm2

Hello @sean I followed these instruction and all worked fine so far. I have one problem tho:

after installing pm2 said:

  Make pm2 auto-boot at server restart:
  $ pm2 startup

When I run it it says (replaced shell user name):

[PM2] Init System found: systemd
[PM2] To setup the Startup Script, copy/paste the following command:
sudo env PATH=$PATH:/home/{SHELLUSERNAME}/.nvm/versions/node/v14.17.0/bin /home/{SHELLUSERNAME}/opt/pm2/node_modules/pm2/bin/pm2 startup systemd -u {SHELLUSERNAME}--hp /home/{SHELLUSERNAME}

So I run the command but I get the following error:

{SHELLUSERNAME}is not in the sudoers file.  This incident will be reported.

which is to be expected... but I hope there is another "hook" to attach pm2 to so it can restart when the server restarts?

could you help me with that? thanks!

yk_ you can use a cron job with @reboot as the schedule to run anything you need to run at startup, eg first run crontab -e in your shell then:

@reboot ~/opt/pm2/bin/pm2 start

sean I was able to add this to my crontab file. Hopefully it will work on restart. Thanks for the help!

sean I've been playing around with this, and I think the command to bring pm2 back along with any saved apps is actually pm2 resurrect. pm2 start wants a config file argument to start a specific app.

db122 thanks! I really need to sit down with pm2 and figure it out before I give out any more bad advice 🤣

sean You and me both, brother! PM2 is pretty unintuitive but it's the best we got, I think!
